Jetting!!! Again and again and again!
livenlife699:
Hmmm Def got me thinking! When I swapped from the 168 main to 175 it ran better both down low and up top so I was planning on trying a 178 or 180 main with more adj on air and smaller pilot? I will have to say that I officially hate jetting! lol

I didnt read your first post..
But if your motor is stock... with that jetting (178)... somthing is up.
Float hight... or air leak..
Ive seen it many times... guys Jetting their bikes... thinking their jettings wrong.. when they are only compensating for other "issues" (air leaks)
jonny500:
so do i. i wasnt saying you should go down i just thought i would add that info to the thread. if your engine is running better as you go up in jet size then go in that direction. 168 main is standard so 180 is getting high. what altitude and temp are you at, are there any air leaks
livenlife699:
Where should I check for leaks? Only place I could begin to think is the airbox to airboot..I did seal it up but maybe Its leaking air..The bike sounds good until I give it full throttle it loads up but loads up less than it did with the 168.
