    I have 2000 Yamaha blaster 200cc. When I ride it the throttle is really not their. Sometime when its warm up a little sometimes it starts to rips but, It doesn’t really rip in any gear. I check the compression And I had low compression, so I put a new top end on it and I still have the same problem. I really don’t know what it can be. It was running good before the tors is still on but the wires for its removed any help.

    Check your plug to see what color it is.your jetting could be off. What kind of rebuild kit did you use? What carb is on it?what mods like exhaust ect. The more information you provide the better.

    The color of the plug is like a oil brownish color. I rebuild it with a wiseco piston. The carb is a miulki carb. I don’t have any mods everything is stock.

    You have. A picture of plug? What size main jet is in the carb.? Needle in the middle position. Are you getting full throttle? What oil ratio are you running if you are not using the factory oil injection? 32:1 is what is ussualy rin in these. Are the reeds sealing tight.you can shine a light in intake boot when carb is off to see

    Everything is on the blaster is stock. So the Jett should be a 230. The ratio should be 32:1. I have not did no upgrades on it. It was running good before. But I have not did nothing it’s all factory, but the tors wires are cut, but still ran fine like that.

    Did you check the reeds?float hieght.carb squeaky clean.air filter clean.fresh fuel. New plug. You have to start checking things. If you are going to solve your issues:rolleyes:.if it's all factory is the oil injection still hooked up?you. Can't premix and run oil injection. Has to be one or the other.

    If you put a new piston in a worn bore you wasted money.
