Rovan Baja FCT-05 Dual To Single Ring Conversion With Brake Tech Tips To Start!

[@eastsiderc]

NOTE!! ATTENTION DO NOT use any of the rings from the dual ring piston they are GARBAGE! Use a new piston and a new ring! I had problems that are now resolved!

[@soblessed6438]

First😀! Boy i know this video wasn’t easy to make, but you did an amazing job on it. Explained and showed how to do everything so well and great editing. Thanks also for acknowledging me. 😊 Can’t wait to see it rip!

[@eastsiderc]

Aww thanks mom. And you must be acknowledged , first you brought me into this world and lead me in the right direction and from a little kid all the way to now you and dad have supported me in everything I have wanted to do and do! I love you guys to Heaven and back!! Thank you mom! Looking forward to us brapping together when I get this car out! We are going to run this thing hard !! Hahaha! Braap Braaaap!

I dig the hammer finish Brotherman👍👍👍👍

[@eastsiderc]

Thanks bro something different ya know

[@kgm5512]

Great video brother!!! Very thorough explanation. I will say, when I do my top ends I have gotten into the practice of gapping the ring. Just something extra, probably not necessary though

[@eastsiderc]

Well its a great practice to get into. I checked the brand new ring that I had to use in this engine and the there was no gap it was fully closed! And boy what a seal inside the engine over that garbage dual top ring I used. What a mistake bro! All good now

[@bluegroovemodelsports9650]

Hammer finish looks great

[@eastsiderc]

Thank you my dear brother Robert in Christ!

[@tonymanna9160]

Great job brother.

[@eastsiderc]

Thanks bro it became a headache later 🤣🤣

[@Js_junkyard]

Great video, I’ve been wondering how this process was going to play out.

[@eastsiderc]

It runs good now very very crisp! Im going to run it hard bro lol! 😂

[@thatoneguy2756]

Yep that 222 is so nice!

[@eastsiderc]

Yessir !! Make sure it has the MS that’s important lol

[@eastsiderc]

Thanks brother Mike!! Appreciate you bro!

[@carbrc]

Such a clever idea with the double to single ring👍.. one massive problem tho .. any idea ? Also a huge difference between piston tops.. single is so much better.. it should run sweet 😊

[@kanenstuff]

That's a great tip do you ever put a bit of grease on those clutch gears. The single ring conversion is something I hear a lot of not sure why they want dual rings.

[@eastsiderc]

Hey brother , never any grease in the gears it will just fling off and attract dust. Those are hardened gears made to run in sand without a cover. They are called BlackBone gears and they are next to indestructible but sometimes I think over heated and when quinched in oil they warp slightly causing the issue I had with the 19/55 set

[@kanenstuff]

@eastsiderc for sure no grease if it's open that would be a disaster. What about if your using cheaper or stick gears and have a dust cover. Or is it still OK if it's buttery smooth.

[@eastsiderc]

@@kanenstuffyessir no grease is ever needed on those gears! Even with a cover they will still attract dust. Most of the time stock are plastic for the big gear and metal for the pinion. But they do make steel ones and there is never a need to grease them up. You will be fine brother.

[@kanenstuff]

@eastsiderc perfect I will remeber that cheers.

[@readeracingRC]

im curious?? im from the 2 stroke day racing MX. back in the day.,... On your RC cars, do you worry or doesn't matter or concerned about the ring end gap. I didnt see you doing it so maybe they don't worry about that on RC rigs. im just curious. Great video. alway like watching the detail you take on the truck's... have fun.

[@eastsiderc]

Absolutely bro , first thanks for watching secondly the ring gap location cannot be adjusted its determined by the pin in the piston as you already know so the location of that is very important it must be positioned away from the exhaust port and not up in the intake. Mainly away from the exhaust port as the heat will open that gap. But once in the cylinder the ring closed around the pin and can no longer move so it will stay put. Thats for the great question!

[@readeracingRC]

@@eastsiderc well. that's not quite what we did. they didnt put pins in the pison to stop it from moving around. we would by over sized rings 2 or 3rd over. then line it up in the cylinder with the piston to have it perfectly straight horizontally.. ands them measure the distance between the ring ends gap. been long time but 4-5 thousands gap? and if the ring gap was to big we throw out the rigs. if to tight we would very gently file off the end and keep checking until we were in spec. if that makes sense.. but with the pin in the piston could make it more difficult. but doable. sorry i had a flashback from the 80's... lol have fun

[@InTheDogHouse3DPrinting]

As he stated, there is a pin on the piston to locate the ring so it doesn't sit over a port in the head. The ring gap can be checked, but I have never checked any of the motors I have built to see what the gap actually is. I will check mine the next time I tear it down to do maintenance on it to see what it is. Over the years that I built motors I always checked the ring gap to make sure they were all the same.

[@eastsiderc]

@@InTheDogHouse3DPrinting yeah if this was an important engine I cared about Id check it but its close enough for chinese specs 🤣🤣. I just fired it off she seemed revvy but definitely needs a tune! Its terrible terrible humid out! She was not happy with all the fuel,

[@bugbashing]

Howsit eastside again asual awesome video,im having a problem with my 30.5 ported motor,on full taps it sounds like its bubbling like a splutter,ive changed coil,ive fitted a new carb checked the air gap over and over changed the ring ,made the squish smaller and still same problem ,no matter where i set the new carb makes no difference hopefully ur input will me thanx brotha

[@stuch77777]

Do you have the part numbers for the new ring and piston also the base gasket please?

[@eastsiderc]

Yessir the ring is RV670095 and the piston is RV670085 you can get that from fearless RC for about 20 bucks for both! Dont forget to use the code FIVEOFF for 5% off!

[@stuch77777]

@@eastsiderc Thankx Brother.

[@claudekim7876]

i had a question, your tune video you mention your idle needle should be all the way out and just till it starts moving the throttle butterfly. but im at stock settings on my 990 and cant get it to idle without the needle nearly all the way in. its a brand new 290rc and a 990carb (brand new)

[@eastsiderc]

Adjust your low brother and you can crank the idle in from where I say to set no more than a turn. From the sound of it your low needle needs more fuel. Im going to do a tuning vid with the car soon and make it make all the sounds of rich and to lean. I really want to help you fellas stay in the gas hobby.

[@eastsiderc]

Base setting are for starting the engine once running you can set a base tune then run the engine and get it fully warmed up before making a final tune. Once optimally tuned you can pretty much leave it there and it will only call for a slight adjustment one way or the other depending on drastic ambient temp and humidity changes. I hope you get it. Please leave me a new comment on the latest videos I post if you need more help bro. Thats what Im here for.

[@claudekim7876]

@@eastsiderc its actually far too rich. My plugs soaking wet and boggy. But thats the recommended stock. Its weird when i was first breaking it in it idled really well at stock.

[@eastsiderc]

@@claudekim7876 your diaphragm needs to be replaced in your carburetor, bro you’re flowing too much fuel if your plug is soaked and you’re at base settings you have a diaphragm issue you got fuel delivery problem happening

[@eastsiderc]

@@claudekim7876 you can also try leaning it out some man it’s hot outside the engines. Don’t want a lot of fuel right now.

[@Js_junkyard]

Also what pull start is on that Rovan motor?

[@eastsiderc]

One you dont want 🤣😂! Its the basic easy start , not heavy duty however works fine but if you want a better nice compact ratcheting pull start look at the Rovan RV85311

[@Js_junkyard]

@@eastsiderc does that clear a victory pipe on the 38cc in the 30degree truck? My Taylor 35 pull start is very close to the pipe, if the ro an is taller it may not work for me.

[@eastsiderc]

@@Js_junkyardit should as its not as thick as the Taylor pull start! Thats a fat boy!

[@Js_junkyard]

@@eastsiderc my Taylor pullstart is about the same size as the one that came with my engine. The rovan looks big in the pictures.

[@eastsiderc]

@Js_junkyard bro I will measure the one that comes with your engine and this 85311 for you. And get back to you shortly

[@InTheDogHouse3DPrinting]

How much of an actual difference in performance would this do? I think it would be negligible myself. I don't see how a second ring would make that much difference.

[@eastsiderc]

@@InTheDogHouse3DPrinting we had a dual ring 50 that TMR built it ran terribly hot we removed the second ring and it made much more power and rpms and ran way cooler. Also the 45 dual ring same thing I had one it was a turd I removed the dual ring piston it ran cooler and and made way more power its in my Maxt now. The dual ring for our rc application with the rpms we put these through created extra friction…think about it a ring drags in the cylinder wall so two rings dragging is twice the friction. Its okay for a chain saw but not our engines or my KTM 300 cc 2 stroke . Only one ring my giant bore 2 stroke!

[@warrendavidson7285]

Where can I get a single ring piston for my Rovan 45cc?

[@eastsiderc]

Fearless RC and get a new ring DO NOT USE THE RINGS FROM THE DUAL RING PISTON!

[@warrendavidson7285]

@@eastsiderc thank you.

[@InTheDogHouse3DPrinting]

Do you have a link to TMR's site? I'm looking for an engine for my new Baja build.

[@eastsiderc]

@@InTheDogHouse3DPrinting you can find him on facebook bro under Cestra Racing Engines

[@SmilinRC]

I have been a MC Mechanic for over 25 years........ Just curious why you remove a ring? What's the logic?

[@eastsiderc]

Dual ring on a 20,000 rpm engine is double the friction it’s completely not necessary was an after the fact. These engines have always been single ring the dual ring is just another bad Chinese Idea ! But its easily fixed

[@donaldmosby6931]

Good morning, EastSide RC . Can you help me. Newly retired and looking to get into the 5th scale hobby. What is a good starting point. I do have some electric rc experience ,I now the time to enjoy things . I'm starting with a $1500.00 budget. Can you help me, thanks, and have a Blessed Sunday Service .

[@kingkongrc247]

Check out fearless rc they have a great selection 👍🏼. Eastside is definitely the guy to talk to 👍🏼👌👊💪🏻💯

[@donaldmosby6931]

That's a will do, thanks.

[@eastsiderc]

First congratulations in retirement! Im 8 years away from it myself. May the good Lord bless you brother. Any way yes Fearless RC is a great place to get rigs. The bajas are nice and affordable. I would not get a dual ring engine unless you fell comfortable changing the piston and ring out. The dual ring engines are 36 and 45cc so keep that in mind when browsing the rigs. Taylor RC has nice rcs as well. Hope you have had a blessed Sunday too brother!

[@donaldmosby6931]

@eastsiderc thanks for the info. I'm looking forward to doing more research wrenching . Ill probably be asking a few more questions if you don't mind. Thanks again.

[@eastsiderc]
