I had the bike idling and it was idling high, then as soon as i touched the gas it sounded like a plane taking off, the rpms kept increasing till it sounded like it was maxed and i couldnt turn it off. Tried the switch, and yanking both plug wires, it kept going. As soon as i pulled the choke it turned right off. Then i started it back up a minute later and it was fine, still idling a little high though but not like before. Then a little later it did it again! This time i again tried the switch and nothing but i knew the choke would kill it and sure enough it did. The bike is really sluggish in the midrange aswell. The weather today was also very cold, it was maybe 20 degrees. Can that cause any of this? Normally i wouldent even ride on a day like this but a few friends managed to talk me into it.

It only does it once in a while? then after i shut it off its fine again?

My bike gradually keeps going up in rpms to the point it wont go any higher and it wont shut off except by choking it. The switch wont shut it off nor will pulling both plug wires?

I constantly check the bike over anyway and im trying to clean up the bike and simplify things, so is the coolant tank really needed?

anyone? this is the only thing keeping me from riding

I need the little adjuster that goes on top of the carburetor to tension the cable on a bike with a tors eliminator kit. Mine cracked off and i cant find one anywhere.

im running yamalube, i wanted to give it a little extra oil to break it in but i guess i went a little overboard.

Im mixing 24:1 and i cant get the bike to stop backfiring, despite getting lots of fuel. could it be im running too much oil?

I rode it for 2 hours today so im sure its fine, i think the connector burned off very shortly after starting it

the carbs are mikuni round slides that measure 1.25in id, and for now its just stock porting but the guy who did my cylinders raised the ports 1mm

btw my elevation is 190 feet and it has fmf pipes

I have a 4 mill with 65.5 pistons, 20cc domes, and carbs measure 1.25in. It has power but pops every so often and the plugs are soaked. Im gonna check what jets in it tomorrow but about what jet should i need?

On my bike some dumbass used all the same color wire for the whole harness and i actually ended up riding with the yellow and black hooked together for a little bit till the connector melted off :ohmy: . I thought i had it right since i put it back exactly like the old one came off but it mustve been switched somewhere along the line of troubleshooting. Anyway with the wires conneced right everything works fine but do you think i did any kind of damage to the stator in that little time?

Does anybody sell a coil that has terminals on it so the wires can be changed? Higher output is also a must

mine like to fall off also, i think the problem is that they make them to fit different size carbs so the fit isnt going to be that great unless your using the biggest carb the filter will accept. Btw you will be really happy with your engine, it sounds like the same one i got and im really impressed with mine
