im positive i put the key in right, i had the identical engine on my cag and it wheelied due to the shear power! has me stumped, i did pull it apart to install a full circle crank though so ill take it apart tomorrow.Hate to ask but are you sure when you put the rocket key in that you put the step towards the exhaust?
I only lighten my flywheels on most of my cags to 12 fins for my wickedly modded engines that run a tight squish which makes engines run hot but cooling isnt too affected when you add an all aluminum pullstarter that becomes a heatsink to draw heat away....Another thing that makes them run hot is airleaks,,weak anemic fuel flow,,improperly jetted carb.....i took it apart and everything was dead on. i think its the cheap dellorto clone. and the old age. actually alot of things. i need to rebuild it badly. i was goofing around in the mud and it got alot hotter then what i would of liked and died, im pretty sure i cooked the piston and rings. and probably the wrist pin bearing. i mean the engine was smoking! and not out the exhaust. i let it cool down and when i shot some WD-40 in the carb it started and ran like nothing ever happened. i think the carb and clutch combo is drowning the gains of the modded pipe. the clutch is seriously working against me. if i had a good stocker id "cam2" it but i know its done. she slips on dry pavement. im not a big fan of lightened flywheels because of less cooling but im considering it....
im running a stock head. i think my carb is shot. cant wait till my manifold gets here. i havent pulled it apart yet. i was too tired from painting my camaro. im actually amazed it started back up!I only lighten my flywheels on most of my cags to 12 fins for my wickedly modded engines that run a tight squish which makes engines run hot but cooling isnt too affected when you add an all aluminum pullstarter that becomes a heatsink to draw heat away....Another thing that makes them run hot is airleaks,,weak anemic fuel flow,,improperly jetted carb.....
Check the rings in the piston to see if theyre loose....
How did the copper ring look when you seperated the headcap?...Any black marks from compression loss?
When you reassemble it do a squish test and compression test on it...

Yes but theres a tolerable amount..Too much and youll get harsh harmonic distortion at high revs........I use anerobic sealer to set the bearings in the case so theres .009" of side play on both sides of the crank...riddle me this, is it normal to get any endplay on the crank(in and out movement)
I just ordered a whole bunch of parts Im gonna be trying the 44mm 2 pc 3 port head. I'll let you know how it stacks up against the 1 pce head with similar mods done. I REALLY like the 1 pc 3 port though, there is absolutely nothing wrong with it.i honestly dont think im doing a twin carb on my quad. im looking at a nice 3 port 2 piece head for it, it pains me that its in the shape its in because its suppost to snow for 4 days and i wanna play some mountian madness =( i got a nuked piston with clutches to match....
