Yes, stock tank with remote petcock attached to the frame where the stock airbox normally connects.
You could probably change this one over to an 'H' 4 spd. standard clutch and w/ the mods you do could probably get it running 65+
No 4 speed for this bike, next build will be a H bike.
This present K1 w/ it's auto-clutch would be perfect for taking the MC license road test.
What fuel tank and fuel valve do you have on it now ? Stock tank w/ remote fuel valve ?
