What bike is this for?
if you got it open it wont hurt to add 4 windows to the piston,,deburr the edges and raise the sideskirt profile a tad,,widen the intake and exhaust 1/8" on each side and reinstall without a basegasket to raise compression..Couldnt get it to start. Had what seemed like low compression, cleaned the carb, which wasnt dirty, swapped for my other stock clean carb, disconnected every single wire, switched plugs, which has spark, but weak one. Going to clean up the coil next and try that. But wanted to pull the head to check the rings to be honest, and see how the top of the head looked. Everything checks out, so i wanted to attempt to port it, but a friend of mine who has modded a couple gopeds suggests i get the **** thing running first.
Good idea, so imma get a gasket set, clean the **** up and get all the grease off, then button her back together and attempt to start it.
sam is still working on my other one, seriously not concerned with that one. That can come back whenever he is ready because that one will be ready to run. Excited? Definitely, but good things come to those who waitI'm guessing that u didn't get the other engine back?and did ur parts come for ur x12?
for what? whatchu gotYou should send me one of ur windshield brackets or ur front fairing support bracket![]()
What do you go off of when adding windows to pistons? Try to match what yours usually look like yeah, but I don't wanna damage the integrity of the piston to a point where it send a piece of metal through the crank lolif you got it open it wont hurt to add 4 windows to the piston,,deburr the edges and raise the sideskirt profile a tad,,widen the intake and exhaust 1/8" on each side and reinstall without a basegasket to raise compression..
Your startup problem sounds like a faulty coil............
You keep the windows inside the width of the transfer ports on the sides....If you put the 7/64" holes where I put mine then youll be ok,,,,any higher and youll be in the ring lands and any lower and youll be drilling through the beefy part of the pin journal which will slow flow and render the mod pretty well useless..When pistioned properly itll drill through perfectly in the right spot.............What do you go off of when adding windows to pistons?
