Thanks,after the mock up photos I dropped in a 55 pilot,air screwed 1/1/4 with fresh fuel 40.1,added some grips the old ones disintegrated in my hands,even with the rear roached tire the front end does its dance with a roll of the throttle,id like to find a 89kx 250 tank but if i don't ill make the yam dry ice tank work,plan on racing it at mammoth once a year. I currently ride a rotation dirt bikes out of my back yard every other day. Have a great one.
