no fuel coming out of overflow , plug is carbon soot black. dont get me wrong some jets with screw adjustment had better results than others,but all still bog in mid throttel and stall bike out at wide open throttle. bike just rev's up quicker with some jet set up than others.

 

What is the stock jet size and what sizes have you tried?

 

stock is # 55 . I have tryed #65, 67.5, 70, 75,80 every body with aprox.the same build is running #75 or #80

 

OK, Please explain canister (pipe). Are you refering to the silencer or the expansion chamber?

 

the lta 50's have no expansion chamber,[stock] so when i say i cut the pipe i'm reff, to the silencer.
