Hey guys,
my problem right now is that when i'm riding, the bike starts to studder in 4th gear at about 5500 rpms...i have replaced the battery, fuel filter, and also the oil. i am completely baffeled about this and was hoping that you guys, being much wiser could help me.

 

i have a similar problem, mines stutters around the 7000rpm in all gears, i know of someone else that had this problem and he got his carbs balanced and it solved it, first it look at the air filter and plugs

 

Hey! i just solved the same problem in my bike!!!!!!!!!!!!!!!!!!!!!!!
you know what it whas????

AIR FILTER!!!!!! NOT ENAF AIR!!!!!!

i thinking that my air filter if pretty clean and it looks like it klean but it was not!!!
i remove it and just for a moment put sponge filter...
my bike runs like a hell after this!
before i comeplitly clean my carb... and start thinking about sincronization!

so let's chek your air filter and eaven try to run without it (dont forget to put some filter marerials in air duckt)
and i belive your bike will feel much better!

 

Thanks guy's...i cleaned my k&n filter and put it in...man what a difference. Thanks again!
