helped a ton, brand new predator 212 non hemi, removed governor, air filter, arc billet flywheel, 22lb valve springs, just fired it up ran good for 10mins or so, shut her off changed oil i let it sit for awhile then when i cranked it up again it backfired (thought it was a carb problem thought i flooded her) and the pull cord slapped against the motor like how u described in the end of vid, tried the lash tighter than it was and its running again👍🏽👍🏽

[@Guido19]

Oh yeah bro that’s awesome! Glad it helped!

[@rideough]

Thanks dude…the explanation at the end helped me. I couldn’t figure out why it was kicking back. I’ll be good to go now.

[@Guido19]

Awesome! Glad it helped!

[@thepapertygeryt]

Very helpful video I used to install my pair! Engine runs better than ever!!!

[@mozzde4675]

Hey when this motor was fully built in the video what did you have inside I’m trying to build your motor seept by step

[@MikeBeatzcom]

So before you install the springs, what else have you installed on that motor?

[@Guido19]

I have everything done to it. If you see the other videos i have I have done pushrod, rod, cam, flat top piston all sorts of stuff.

[@sausyhd3006]

Great video, just wanted to know what length your pushrods are ? And if they are chromemoly, maybe if you could send a link that would be great.

[@Guido19]

Hey thank you! I don’t have a link unfortunately but they are just the stock length but chromemoly. I made a whole video on them! kzbin.info/www/bejne/emW1qoCQmpydec0

[@ThisTall]

Great job! I got a 212 clone and noticed I only had a valve cap on the exhaust side. 99% sure I didn’t drop the intake side into the motor but don’t know why there would only be on 1 side. So I’m worried I have to crack the motor in case I dropped it.

[@Guido19]

Actually you should be good! Some different clone motors only have 1

[@ThisTall]

Turns out I didn’t drop it. Only the exhaust side has a valve cap, and the intake side does not.

[@Guido19]

@@ThisTall yeah. Sometimes they can be the other way around on a lot of the Chinese motors

[@ThisTall]

@@Guido19 unfortunately I was wearing headphones when taking the rocker arms off, so I couldn’t hear if it dropped out lol So I was stuck trying to confirm online for 2 hours wether I had to split the motor to find it. Happy ending though.

[@Guido19]

@@ThisTall oh man that’s what happens lmaoo. I always just wanna listen to music but can’t hear anything

[@Pen2Reel]

how would you put the piston “top dead center” like you said ? and what tool did you use

[@Guido19]

You gotta slowly pull start the motor over and remove the spark plug till the piston is all the way at the top. Also take off the valve cover so you can see the rockers are lose and there’s no tension on them

[@kaleayahstrayhorn3683]

Yo bro i have a hot265 cam and 26lb springs what lash should i set it to the .003?? Or .002 because its not starting and its kicking back i have billet flywheel timmed and billet rod plus a mikuni jetted

[@Guido19]

I would make sure everything is all good and legit with timing and your coil gap and if so I would probably do .002. That’s what I personally run. The reason it kicks back is the advanced timing and also along with the lash. It won’t be fully eliminated but it won’t do it as often

[@MrLopez-lm4jk]

Ay bro when u put ur 26lb vave springs did u put that lil copper valve seal und r ther the intake valve spring or u dont need it ?

[@Guido19]

No I didn’t! I took it out when I installed my stainless steel valves as mine are 5.5mm and the stock ones are 5mm so the stock valve stem seal wouldn’t fit. It’s not really necessary.

[@mateorodarte1814]

Did you do anything to get the locknut off so easily? I tried but my wrench slipped and I cut myself. Had to get stitches lol

[@Guido19]

Oh wow that’s crazy bro. Hope your hand is alright lol. I cut my finger open too when installing them cause my hand slipped and hit the machined part of the head lol. No I didn’t! It just busted right off for me lol

[@mateorodarte1814]

@@Guido19 Alright thanks! I’ll probably try using oil to try and make removing the nuts easier once my hand recovers. Take care man!

[@Guido19]

@@mateorodarte1814 cool man! Good luck!

[@paulvalge7169]

What was the tool you used to get the 26lb spring back in?

[@Guido19]

A valve spring compressor

[@asphaltcowboy7868]

I'm currently running 22lb valve springs with a 265 cam...it runs great a low and mid rpm range but once I'm wot, it will fall on its face and start cutting out.. I believe I'm still valve floating, so I'm about to upgrade from 22lb to 26lb springs..do you think this upgrade will solve my wot issues??..I'm currently running a stage 4 kit..with the billet arc flywheel which is already advanced..plus a 24mm mukuni carb...so I don't think it's a fuel issue...

[@Guido19]

Hmmm personally I would consider going just a bit bigger. Going to a 26lb will be better but if you get 32lb or 36lb you will definitely notice a difference for sure and you will get more performance for sure!

[@ayodevin4017]

If u dont got a pulse pump it may be your engine running ur bowl dry

[@ShafferBrah]

Can we get a link for springs. Thanks for the video

[@jeffruiz6291]

What tool did you use to install the new springs?5:30 thanks

[@Guido19]

I originally actually used my thumbs which is a massive pain but now I use a valve spring compressor which I got from harbor freight for like $25

[@Ramons_10r80]

Can you use 22lb springs on a stock mini bike?

[@Guido19]

Yes you can!! I would recommend doing a different cam, and rockers for increased performance and durability!

[@Ramons_10r80]

@@Guido19 do i need to buy a billet flywheel?

[@Guido19]

@@Ramons_10r80 no you don’t! Valve springs won’t affect the flywheel at all but again it’s a great mod to pick up some performance gains and also it’s stronger so more reliable. If your motor has the governor bypassed or removed the flywheel is a must because the stock one will explode

[@Guido19]

@@Guido19 ok thank you

[@cuh_2023]

The Manual says intake 0.004 and exhaust 0.006

[@Guido19]

Correct but different cams will have different requirements as well.

[@cuh_2023]

@@Guido19 I have the stock cam 0.005 intake and exhaust seems to work well for me

[@Guido19]

@@cuh_2023 yeah that works pretty well stock. If you run a upgraded cam though depending which one you get it might be a tighter tolerance. My hot 265 calls for 0.0003 on both but you could also do 0.0002

[@mjk4378]

I have a 196cc clone motor that I’m putting 18lb springs in it. What number should I lash the valves out too?

[@Guido19]

Man unfortunately I can’t give you a exact number because it may be different but I believe it’s something like 2.5-3 thousandths

[@mjk4378]

@@Guido19 okay. That helps some I’ll call Go Power Sports in the morning just to double check since I got springs from them. I saw on red beard garage, he said between .06 and .08. And somekne I know said he tried .05 and .07 and the motor shut down or something and he said to just set them at 0. Basically just tightens them up when they just barely touch. So I’m gonna try .03 for exhaust and .02 for intake.

[@Guido19]

@@mjk4378 yeah I would recommend doing .02 for both actually. Don’t do anything to lose cause then your pullstart will wip back and hit you. Ask me how I know lol. You also don’t want to have it at 0 either. My motor is fully built and I’m running.01 I’m pretty sure and it runs pretty well!

[@mjk4378]

@@Guido19 lool. That has actually happens a couple times b4. Not very often thou. And I did .002 on intake and .003 on exhaust. Haven’t started it yet. Still waiting on other parts s b4 I put all back tighter. But thanks a lot thou 👌
