My buddy has a 95 XLT 600 Tripple that was bored 60 over. It has not been rejetted. He took the carbs off and he cleaned everything and adjusted the floats. Put the carbs back on and sense then it has a bog from idel till about 1/4 throttle. He said he moved the needle clips down one notch wich brought the needle up and seem to help a little but the bog is still there. This is with the belt off and even with it on it still does it. I have been racking my brain on this and all I can think it would be is the pilot jet is plugged again. Carb's are synced and air/fuel 1 turn out from seat. What do you all think?
I think you are right in thinking it is in the pilot jet circuit. I would try adjusting the air screw although at only 1 turn out you can't go too much richer. Because it got marginally better by raising the needle I suspect it is running lean. You could try going to #40 pilots to see what that does for you. Also check the belt deflection to make sure it is 1.25 inch. These sleds are pretty fussy in that regard and if you have too loose of a belt you get a wicked bog. Make sure the belt side clearance in the primary clutch is in spec. It should be somewhere around .020" to .035".
Idle speed should be around 1800 rpm.
Is this sled piped?
The older I get the better I was; In fact now that I think about it I am a legend.
