Default raptor crab, runs great now, need a little jetting help

ok, i got my fuel level down to the line of the carbs/bowl. using the clear tube method. all i can say is wow! it will wheelie till i want to set it down now. Only thing is this, teh overall jetting still seems rich. Can anyone with similar mods give me some DynoJET jetting specs they run? :Mods Full Yoshi tri-oval pipe system, dynojet kit. I now can run with lid on or off, so what are you guys running. Right now i have 148/150 dynojets, but it seems a bit rich, although it seemed lean with 146/148 setup. this is driving me crazy, cause with the smaller jets it had a big midrange bog that would dissaper when i used the choke. Oh yeah im at sea level.Text thanks uys

148/150 is common with a stock motor, no lid, and an aftermarket exhaust. With motor mods, you're too lean.

If it got better when you put the choke on it was running lean.By putting the choke on you gave it more fuel.That is why it got better with the bigger main jet.I live in new york and the kit ran lean for me.Iended up having to purchase bigger jets then came with the kit.I also run with yhe lid off.You should check your plug .

damn, this is my problem, it seems to have less power at full throttle now, however it bogged hardcore midrange,now its like its to rich, cause it has less power top end. Is it common to run 146/148 with what i have, a full pipe? tahts is what they reccomend with the kit. remember this is a dynojet kit. what are yo guys running for jetting?

Are you going to run with the lid off? If so you might want to go up a size on your mains. When lowering the float level it can require you to go up on the mains. As far as mid range that will be a needle adjustment.

BTW Where can I get a crab for my raptor? I really want one bad![img]i/expressions/face-icon-small-smile.gif[/img]
