bike is a 06 with lunch box. i have a cut down trs yoshi with barely any packing in to its pretty much a straight pipe. the can is about 8 inches long..also how much more effectinve is a after market petcock

20/65/147.5 seems to be a starting point with that set up.
Maybe 20 washer, 147.5 dunno no one has tried it.

I guess check faq ... but prolly take off the caps and put it at 3 turns ?

I use a 20, 65, 145 without problems

but a 20, 65, 147.5 would also be fine.
