I am looking for info about running alcohol in my 2 stroke 400 4x4 polaris. Most race mods have been performed by HPD Inc. Carb I'm running is a 39mm Keihn, need info on converting. The track we run on is mud, 240' to 300'.

its going to depend on your compression

 

I wouldn't mess with converting the Keihn, I'd get a lectron from Dennis packard. In fact you might pm CED on here I think he has a 40mm lectron he might be looking to get rid of. I ran the lectron myself for awhile, very easy to tune. I ditched the alky though and went with hpd powermaxx setup, wanted to do more riding than just dragging and alky got to be a pain for me. Good luck!

 

yeah! what he said. [img]i/expressions/face-icon-small-happy.gif[/img]

 

Eddie (esr) actually has a very good setup for the keihins. its a stock 450r carb that is reworked on alk that runs well.

Otherwise i would run a 44 from Dpack
