Yamaha Banshee Engine Break-in How to

[@acemaster1001]

I agree 100% with this. MOre oil makes a colder burning FLuid. Oil is a very slow burning liquid. When i first bought my Cr 250 way back a few years ago. I went from 32:1 -50:1. The bike leaned out and worked awesome. NO jetting needed. The more oil you have the colder the burn. That is a fact.

[@SparkysGarage]

I get a solid 4 years of HARD riding when I do my rebuilds like this. I haven't found a better way to break in a 2 stroke. Just make sure your jetting is on and you have no intake or exhaust leaks. Check out my vids on that too.

[@SparkysGarage]

@ChevroletBoy3 I bought my pipes used, I believe they were bare metal or pewter coated then painted black. My recommendation is wood burning stove paint. It is ceramic I believe,

[@SparkysGarage]

@2StrokeSmokes No I spoke correctly. When you have less oil it means there is more gas entering the cylinder on each stroke. Therefor it makes a rich condition. So if you run 40:1 with the same jet(s) as 32:1 then the 40:1 engine would be running richer.

[@SparkysGarage]

The engine is broken in after a few heat cycles. I would say after a couple hours of riding and letting it cool down then you should be go. Don't forget to check for intake and exhaust leaks a lot while breaking in the engine

[@2StrokeSmokes]

@bozillakilla know that too much oil can be a bad thing. It can cause the plug to fowl, carbon built up, and because the oil coats the cylinder walls, cause the engine to get hot. Lean will simply starve the engine of the oil it needs.

[@SparkysGarage]

@codyraab1 It is always important to let the quad warm up to operating temps before you ride. I would use this same process for breaking in a 4 stroke, however breaking in a 4 stroke is much less critical then a 2 stroke.

[@SparkysGarage]

Well there is no cam so you don't have to worry about that :) If it rides fine then keep riding it. Do a compression check though and if it comes back low then do a rebuild

[@SparkysGarage]

@DaMonsterMonster I realized that. For the most part in the 2 stroke quad world when we refer to lean or rich is gas/air. Not fuel/gas. Sorry for the confusion.

[@SparkysGarage]

I explain this all in my oil mix video. It makes it richer in a sense of oil/gas but leaner in the sense that matters more, which is gas/air. If you watch that video you will understand.

[@2StrokeSmokes]

thanks for the reply man. Your videos are a inspiration to get my shee done out

[@agnosticfrontliner]

the variation in the RPM's is for when you're riding and breaking it in so that you can't get a "dead point" in you cilinder/piston because its worn out by staying at the same RPM's for too long and it's kind of hard never to let it idle I only ride my (2 stroke) bike in the weekends and I'll always let it idle for like a minute or two , just to make sure everything is well lubricated then I ride out but keep it in low rpm's till the engine is warmed up and after that its just plain fun

[@acemaster1001]

I dont know if i agree with this theory. Oil is SLow burning. When you have a slow/cold burn, you run rich. ITs not the same as running different jets, Because your Gas:oil ratio is now slower and colder when it ignites. I get how the oil and fuel runs slower through the jets and that would make it run leaner when more oil is added. But, If you have alot of smoke from your exhaust, YOu are running rich/colder because the oil doesnt burn up 100%. And thats why you get smoke.

[@troyberry2797]

Hey man great job I did the same thing you did and I’ll do it again thanks

[@SparkysGarage]

@DaMonsterMonster We are talking rich in a sense of fuel/air mixture. Not in a sense of fuel/oil mixture.

[@SparkysGarage]

@Sandeep9201 Unfortunately it is an opinion thing. By lettering my banshee warm up before riding the top end lasted 4 years... So thats what I do.

[@acemaster1001]

That theory only applies with jet changing. Once you start to fuck around with oil/fuel mixtures. YOur fuel burn slower and colder when you add more oil. Which makes is rich. Its not the same as doing a jet change.

[@SparkysGarage]

I would recommend either not using the res or mount it in a different location.

[@Monkeypumper420]

Wrong. Engines(2 stroke) do not seat with "heat cycling". That's a myth. New engine parts are precision and already treated when built. Once built, you warm the engine fully at idle , then ride it hard. This seats the rings against the cylinder wall perfectly, and you have a very short opportunity to do this. Within a 20 min period or so. Motors run in this way last longer, run harder and make more power. I've done it this way since I was told to do so against my will. I am a believer, and follow this guideline strictly.

[@chadwems]

that's what my co worker did with his wr200. he said he rebuilt it. let it warm up. then rode the hell out of it. not wide open. but she didn't blow up. or seize up

[@jrrivers4140]

Monkeypumper420. all engines need break in dont fool yourself.

[@2StrokeSmokes]

When its too much oil, its rich. Too little oil its lean. I think you meant to say rich at 3:16. But other than that I have to agree 100% what you said. I do it the same way with great results. By the way I have to say your one of few that would agree with me that running more oil in the gas on break-in is a shitty idea. Run the same 32:1 mix with 2R, always.

[@SparkysGarage]

It's a guess. There is no way to tell how dense the metal is or how fast the piston rings are seating. Usually after a few heat up/cool down periods then you are good.

[@SparkysGarage]

Right around a 280 should be good after you get an exhaust. Also switch to a 27.5 pilot when you get an exhaust. As for now, what are the symptoms to where you think the jetting needs to be changed? A 240 sounds rich to me with just a filter and reeds. Maybe try a 220?

[@bobby6631]

same break-in procedure as with my rc nitro cars!! great ridin skills btw!!!!

[@SparkysGarage]

@MultiFordpower If you are running conventional oil like yamalube or something along those line si would run 32:1. If you are running a high quality fully synthetic oil I would recommend 40:1 due to the extra wear protection. Correct, I dont go past 3rd until the break in is done. The powerband really depends on the individual machine and setup but most banshee's will hit the powerband before 3/4 throttle, so usually yes. Thanks for commenting! Let me know if you have anymore questions.

[@marcusfrancart]

i always ran 32 1 when i first fire up after rebuild i ran a lil heavy on oil on break in but thanks now i know not to do that although ive never had a prob on lasting motors

[@SparkysGarage]

@DaMonsterMonster No mechanic anywhere in the world can tell you exactly what jets you need, that can only make starting reccomendations. All engines, air temps, humidity, altitude, air density, compression, mods, ect cannot be taken in account for unless you do plug chops or something similar....

[@ImFromDadeCounty]

Just put a new set of wiseco pistons, ran about 3 full gas tanks threw it. It runs like it did in '06.

[@SparkysGarage]

Armando Acosta Awesome!

[@SparkysGarage]

I didn't cut them. I bought them like this, and yes they are cut about 3-4 inches shorter.

[@SparkysGarage]

Yes, stock carbs. 290 mains K&N air filter with lid. 40:1 gas/oil. 1000ft elevation 60-70 degree temps.

[@SparkysGarage]

@DaMonsterMonster From what ive read the stove paint works better... I haven't tried either.

[@supertruckerrolling]

Anytime you rebuild a two stroke you should run your fuel mix a bit richer and or adjust the jetting. Don't go real long hi rps get the engine good and warm let it cool then repeat. Use a lot of up and down speeds from the throttle which you do dirt riding.

[@SparkysGarage]

I did a video on fuel oil mix ratio. You should watch it.

[@supertruckerrolling]

I'll have to check it out I raced motocross for 10yrs I remember when mono shock first came out and was it ever the best thing

[@SparkysGarage]

10 years ago oil technology wasn't nearly as good as it is today. With a quality synthetic oil there is no reason to douse the engine with more oil. It does more harm than good. Thanks for the comment.

[@supertruckerrolling]

SparkysGarage You got that right on the technology. Yeah we never ran it so rich that the plug was real wet just a bit past coco brown. But like you said with synthetics today its much different.

[@RACEMAN669]

supertruckerrolling I have been rebuilding my two strokes since 1978 and never change the oil ratio . If you richen the fuel oil ratio , you have leaned the air fuel ratio . Pre-lube your parts , run your proper fuel oil mix , do an easy breakin . I have had great results with this . In my opinion bore and parts life are improved with consistent tuning , and not letting rings and pistons go till their last leg . An example is my 85cr500 , Still standard bore , MC1 at 40:1 it's whole life . Changed rings often and piston every other time . Yes this bike was raced when new and has seen plenty of use , just got back from pismo . Just my 2cents .

[@caseyniedermeyer5516]

oil does not combust like gas, sir. so there fore, you will run in a "lean" air fuel mixture. i couldnt really see it as being "bad" for the motor, i just think it would screw you up on your jetting. making you think your jets too big or not big enough and you constantly go back and fourth, witch then you could think your good, then drop your ratio of oil/gas and run lean and screw things up.. but idk hah.

[@SparkysGarage]

Do it! Ill help you every step of that way that you need it! Place an order!

[@2StrokeSmokes]

@bozillakilla Yea, ok. But with that mentality the bike will be lubed better with less oil... And my point was not about what ratio is best. For your case I'm willing to bet that it was the fact that you ran the bike for two years rather than the different mixture that blew it up. If you mix lets say 20 parts gas to 1 part oil, its on the rich side. If you mix 50 parts gas to one part oil is going to be on the lean side. More oil makes it smoke more and called a rich condition. And I do

[@2StrokeSmokes]

@DaMonsterMonster thank you finally someone who knows what the fuck there talking about

[@SparkysGarage]

Hard to say, are you sure it was metal and not a reed pedal? Id do a compression check for sure.

[@kevinway1995]

I have a ? I did a whole rebuild on my topend on my banshee and both cylinders has compression of 120psi so I start the banshee up and the right side is backfiring and when I give it a Lil gas the whole bike rumbles and shakes real bad do u kno what that can be sp I need help asap I took the motor completely apart and it was nothing internal put it back together and did the same thing smh do u kno what that could b sparky thanks

[@SparkysGarage]

Sounds like a misfire. Try switching the spark plug wire left to right and right to left and see if the backfire changes from one side to the other. Also throw new plugs in after that.

[@ImFromDadeCounty]

Check ur reeds too

[@Alex_R6]

Check your spark plugs, same thing happend to me turned out to be my spark plug was bad.

[@darryllopez2845]

I just rebuilt my 87 and I started it up first time first kick.. leak leaking on one stud.. pulled apart fixed stud and new head gasket put back together.. hasn't leaked and I've rode it about 3 times up and down my street total maybe 5 mins if that and around my yard in circles a dozen times.. check my compression it's 110 to 112 on left and 115 maybe 117 on right.. new bore new pistons and rings.. is it not broken in yet cause I barely got past 2nd gear or something is up with the build?

[@SparkysGarage]

Its not supposed to be pretty, its supposed to go fast ;)

[@briancanane3924]

Just my to cents, don’t let 2 strokes idle especially on a rebuild , burp the throttle . That’s how they cool off and lubricate

[@SparkysGarage]

You've been lied to. Idling wont hurt if its not super super hot out. If it's really hot any quad without a fan needs to be moving.

[@SparkysGarage]

Anything below 100 and you should be looking into a rebuild on a stock motor.

[@kevinway1995]

Well I tried that to it still didn't work, okay maybe this will be a little better when I first got the bike it was running fine I let my friend ride it and when he came back on it that's when it started back firing and the motor start shaking real bad so I don't know how that could have occurred just by riding the bike thank you Sparky's garage

[@dr.evil2535]

Maybe one cylinder is blown? Dunno but you said you did a rebuild on it again so that's weird

[@kevinway1995]

Yea come 2 find out it was the crank know how its a gold or silver washer on both sides of the rod 1 of them went

[@dr.evil2535]

Wow you don't hear that everyday :) haha at least you found out what it was :)

[@kevinway1995]

Lol I know, and how I found out it was gone I was looking at a rebuild kit for the crank and I seen it had 2 washers 1 on each side of the rod so I looked at my crank and I only had 1, so I put a new crank in her she been running strong ever sense

[@dr.evil2535]

Haha that's funny

[@TheXiledsoul]

nice bike looks really clean

[@Shawi7]

yeah thats what i was thinking how about i switch to the 2 k&n's the mount directly do you think a 240 will be good maybe slightly lean right. Hey thanks for all your help bro God bless you :p really helpful dude

[@SparkysGarage]

@racer9mittler Any good brand name full synthetic oil should make an engine last a long time :) Thanks for the comment!

[@ChevroletBoy3]

Did your expansion chambers come black like that or did u paint them? Im looking to paint mine and was wondering what kinda paint, if u painted them, u used. obviously they would have to be a high heat paint

[@codyraab1]

now on 4 strokes. if you rebuild the top end you can just go out and ride at full throttle and stuff right?? cuz i rebuilt my 185s atc top end and did that and nothing happened

[@alexsbikesandmotors]

you've got it right, bro! These people who rev their brand new top-end to 12k rpm to "seat the rings" or whatever are total yobbos.

[@BrittanyHunter2012]

Hey sparky so I took a 87 an I took a 01 an I wired the harness together I finally got spark but now it's not starting there's fuel shouldn't I get something with starting fluid or something.

[@SparkysGarage]

Brittany Hunter Harness's are cheap, just buy a used one on ebay.

[@MrTunerboy11]

Are you using the stock carbs? So yes, what size of jets are you using? What fuel/oil mixture do you use? Thanks!

[@melbailey83]

my banshee is blowing heaps of smoke from 1 side but it dosnt smell lke 2stroke any imput you can help me wit .. and its not the plug..

[@tegdarkblade]

hey just got a 98 banshee and it has no air box but has pod filters and my coolant overflow tank was zip tied to the fenders how can i make it functional and look cleaner thanks bro

[@Sandeep9201]

I was watching another vid on a blaster and this guy says never to let it idle and always vary the rpm... is that true?? i just want to make things clear so i can break in properly.

[@SparkysGarage]

Yes sir.

[@SparkysGarage]

@alexsuchapimp I completely agree.

[@BrittanyHunter2012]

I need help please I was wondering is the wiring on a banshee color coded

[@SparkysGarage]

Brittany Hunter It is color coded and labeled in the manual

[@SparkysGarage]

Thanks a ton man!

[@SparkysGarage]

@cummins92bankspower Its all an opinion thing....

[@christinamerrell7974]

hi sparky i just got a 421 cheetah cub built an it runs on race gas got it built in PA east coast atv an i live in VA the guy dave is trying to help me get it tuned in so i can ride it but i cant ever get him on the phone real busy is this a gud way to do a 421 cheetah cub or not really need help not that great wit motors any help much appreciated bro thanks

[@2StrokeSmokes]

I got the same exhaust but my silencers are longer. Did you cut them off?

[@MikeSmith-ve2qu]

Don't you let it warm up and rev it up and down a little and not let it idle ?

[@SparkysGarage]

+Mike Smith People do that because they don't want to wait for it to idle on its own. Small revs won't matter, however wrenching on the throttle on a cold engine is never a good idea

[@MikeSmith-ve2qu]

Oh I see thank you.

[@SparkysGarage]

+Mike Smith No problem :)

[@anonymousname1735]

I guess people just dream up ways to "properly break in a new 2 cycle racing engine" just because them and their buddies did it a certain way and it STILL RUNS...?? There is a correct way... (this is close).. varying RPM's.. NEVER-NEVER LET IT IDLE AT A CONSTANT RPM..THIS ALLOWS THE ENGINE TO LOAD UP WITH UNBURNT GAS/OIL MIX. trying to burn this clogging mixture makes the engine run hotter - idling without airflow makes the engine run hotter... even for a few minutes!!! Always ride the bike/atv for break-in ... SHIFT through ALL the gears (don't miss a shift!) then shift back to first and repeat for about 10-15 minutes. Keep the RPM's low and varying!..NO FULL THROTTLE ! ( NO extra oil except what was used as assembly lube!) . Let the engine cool until you can lay your hand on the head and keep it there. Retorque head/cyl. nuts. NO MORE then 10% above factory specs!! Then repeat the going through the gears, going a little higher (and varying) ( NO FULL THROTTLE YET!) in the RPM range this time for about 20-30 minutes. Let the bike cool completely again (see above message)..::>> REPEAT THE ABOVE STEPDO NOT WRING OUT THE ENGINE ONLY SMALLER JETS make the engine run LEAN! The extra oil only makes break-in take a lot longer and foul spark plugs. The oil/fuel mixture is richer... NOT THE FUEL/AIR MIXTURE > DO NOT USE EXTRA OIL! DO NOT use HOTTER spark plugs!!!!!!!!IF YOU WANT A BAD-ASS BANSHEE ENGINE.. YOUR MECHANIC SHOULD KNOW HOW TO MODIFY THE ENGINE CASES AND MATCH-PORT THEM. (THIS WILL BE REQUIRED AFTER CASE MODS.) , , MODIFY THE COMBUSTION CHAMBERS, AND MILL THE HEAD AFTERWARD. If HE HAS NO IDEA WHAT I AM TALKING ABOUT... GET Another ENGINE BUILDER!!

[@anonymousname1735]

+Mike Smith YES!

[@YZ80FAN]

Hey again, I just rebuilt my yz80, and it's smoking a lot, is that cause of the rings wearing in? :)

[@2StrokeSmokes]

I'm going to have to disagree with that, BUT, I'm not about to go into a argument about it. If that's what works for you, stick to it. Your ratio you mix at all depends on the jetting and that's the end of the story, no more to it than that. I have had a yz 125, banshee, and a yz 250 and I have never blown a engine. I mix 32:1 with 2r and my bikes are jetting accordingly.

[@Shawi7]

Ok so my bike's completely stock its an 06 i now have a K&N like yours and took of the snorkel went from a 200 to 240 on the mains and added a v-force 3 reed, went one size bigger on the front tooth so im running a 15/41 now. My fuel mixing ratio is 36:1 to be safe im pretty happy with my bike but want to get more power now im looking for an exhaust but until i do or even if i do what size jets should i run i was thinking somewhere like 270-280 for a T5 or Pro circuit.

[@blakebernardo9513]

how does adding more oil, make the quad run leaner??? We just got our 98 banshee, 4 mil stroker rebuilt, and he said to run more oil for just the first tank of gas???

[@SparkysGarage]

Watch my jetting vid series. Explained it all in there.

[@Shane.C]

So that the engine is lubed real well so that the engine doesn't cease

[@Shane.C]

So that the engine is lubed real well so that the engine doesn't cease

[@notsedsnoyl]

wrong the best thing to do is let it idle up to temp then give her seats the rings much better

[@aliisathug]

how do u do a compretion on a banshee and what a new engen copretion at can u do a vid

[@SparkysGarage]

a 125 is a 4 stroke so its a little different

[@BigJonOnDeck]

what is the correct mixture? how many ounces per gallon?

[@jc18904]

Can u do a video on how to mix the fuel for a banshee or do u have a video already?

[@SparkysGarage]

***** I just use a ratio right cup. All you need to do without one is convert the gallons into ounces.

[@jc18904]

SparkysGarage thanks SparkysGarage!

[@chrisreal4753]

For every once of gas it’s 4 ounce of oil I mix mine 32.1

[@SparkysGarage]

Amsoil 0w40 atv oil or 10w40 motorcycle oil

Thanks for the information

[@SparkysGarage]

No worries

[@bmjca123]

ThNks for the video!(:

[@rickyelementsk8er]

LMFAO at 3:04 It actually makes it richer because its going to burn more oil than gas, It wont be running leaner lol

[@kevinway1995]

I did that to and it was still doing it I didn't change the plugs imma change the plugs and c what happens then and I'll let u kno thanks SparkysGarage

[@YZ80FAN]

How do you know when it's broken in?

[@MainTracks]

what fluid do you put in bottom end

[@acemaster1001]

What r u talking about?? i am saying 50:1 runs leaner then 40:1

[@juheard_joe29]

how do u change coolent do u fill halfway under the seat..and radiator fuild when and how do I change ...(srry first project bike hands on)

[@SparkysGarage]

Take off the radiator hose where it attaches to the water pump. Let the coolant drain. The reconnect it and fill from the top of the radiator.

[@juheard_joe29]
