Brute Force Problems
2006 Brute Force 650. The bike ran pretty good when I first brought it home. Since it's gotten colder it really runs like crap. It wants the choke on all the time.. Seems pretty cut and dry.. It's lean, change the jets. Well I did. I went from a 139 front and 142 rear to 142.5 front and 145 rear. It seem to run a little better at idle however now it runs like crap up top, the only place it seems to run better is in the middle. It's still pretty much unacceptable at idle. I'm not sure where to do from here.
Modified stock exhaust
Modified air box
CDI
Other than that the bike is dead stock. I fooled with the pilots too but it did not seem to really do much.
Any suggestions.

i would doubt the dealer would fix this under warranty if you have modified it. try to put your air box back to stock as i think they run lean from the factory. my bud has an 06 650 and hasnt mentioned any problems w/ his but other friend had an 05 750 and it ran lean to the point of back fireing some times and they put differnt jets in them.

My bf750 was doing almost the same thing. I put it in the shop 3 times and it never got better. This last week they installed a moose ignition module and a jet kit. Now it runs great and starts up right away with very little warm up time. The throttle response is even better and seems faster.
