Hillclimber...whats with the FTR pipe??? Cmon man HPD all the way!!

 

amsoil on the pump in both quads. i just converted the new tb over.

 

I wish I had but I have no complaints with the FTR, however if I could get the money out of it I would sell and buy the HPD.

 

Amsoil synthetic. 50:1

 

From my experiance the blue works ok for liquid cooled 400s but with the air cooled 250s the synthetic oil from Polaris works much better. The blue cant handle the heat and will cook to the piston. I think the blue was really designed for watercraft because that was when it first came out was when they first made them in the early 90s. I have heard of several people who were fouling plugs alot and switched to synthetic Polaris from the blue oil and never had any more problems.
