Need Help Shee running funny

[03bansheeman126]

i just bought an 03 shee. its my first and i dont know much about these things yet. it was running fine for the first two weeks but when i rode her the other day it was acting weird. there was a power lose and a lot more blue smoke than normal. it hardly ever smoked before. i talked to the person i bought it from and they said that it may need rejetted. they said the last time it was jetted it was cold and it was done for the winter. does this make since? could that be the problem? any help would be nice since its my first and i dont know much. Thanks

That kinda makes sense. U need to rejet it for every 20 degree change.

But u could also need a new top end.

check the compression

what is the compression supposed to be on a stock 03? any other ideas?

Yea that makes sense. If it was jetted for the cold weather it is running rich now in the hot weather, therefore you are too using too much fuel and more oil is burning causing the blue smoke you see. And running rich will cause it to run crappy and most of the time will foul plugs, check to see if your plugs are fouled. You are going to have to go down on the main jets to make up for the temperature change.

changed the plugs cause they were pretty dirty. didnt make a real big difference. it seem to be fine after it get warm but still smokes more than normal. and the power lose is still there. sometimes it bogs down and sometimes it doesnt. there is also a knock in the motor. any ideas?
