Default PSI 3 Slide Carb for EVO applications

Has anybody seen one of these or heard how they work? Could this new carb work on a Sportster? The external adjustment and three slide technology sounds like something from general aviation - imagine a fuel mixture lever on your ride ...

Sorry, I'm too new to be allowed to post a link. Google PSI carbs ...

Very interesting. Buy two, send one to me, and I'll give you my opinion about it for free.

It may run better than the stock carb, but you still have to know how to tune a carb. You will still have the problem of the short Y intake manifold and fuel/air charge bouncing back and forth in the intake.

My other question is will it compensate for altitude changes as well as the CV carb does? I frequently ride from sea level to over 6,000 feet on the same day.

I just saw you had an 883. My guess would be to spend your money on a 1250 kit first, if they have the overheating and oil burning problem fixed.

I'd give more info right now, but I gotta get ready for work.

I'm quite content with the 883 as it is. This carb appealed to me more as a gadget. Aviation and motorcycle technology have been cross-breeding for 100 years. It's interesting to see this latest spin-off ...

Lenster, when you have more time, tell us a tale about your PSI.

Interesting... Can you give us an example of of this unholy cross-breeding of aviation and motorcycle technology that happened later than the introduction of the radial aircraft engine???
