I wonder if your running a little lean in the jetting now. That could raise the temp.

 

what should I do to adjust this?

 

no disrespect intended merlyn, but you need to provide more information. Is there someone who can help you with this? drilling a couple holes is not likely going to cause "running hot" unless you drilled them in the radiators.

 

after I ve drilled the holes I ve observed that when I run my bike in the city traffic conditions the temperature is always after the middle a bit

 

Hell, that's normal> don't worry about it if you checked all the other stuff i cited previously. grow some *****! Take the whole rear baffle out, that is, cut the whole center out. The sound is glorious and it won't hurt a dam thing. then you'll find out for sure that you're not going to overheat. If you run good synthetic oil, heat is not a problem. you can run well over 200 degrees and never hurt anything.

 

thanks! I run motul 300 v racing line double ester 10w40
