Jetting a 38mm airstriker

[swindog]

Hi guys, going to try run a 38mm airstriker just to try something new. I know alot of guys run them but I cant seem to find a thread about jetting them. Will the jetting be much different to a 39mm?

I usually run 55 pilot and 170 main, 3rd clip on needle at sea level. Any recommendations for a similar starting point on the 38mm??

Thanks

Depends on what needle you intended to run. I have played around with one for a short time, but never got it quite where I would like it. Maybe in the near future I will get back to it. A few people talk highly of this carb but I have yet to see any jets/needle that would get me close. Extremely rich down low. If you are running a new one from sudco, don’t bother with the DDJ needle. You are better off using the stock needle out of your stock carb. (Still not ideal, in my opinion).

Mmmm most interesting.. I've heard someone say one of the benefits of the 38 airstriker is they are easier to jet. Doesn't sound that way!

Thanks for the reply lads, I'll get my hands on a N8RW needle and have a crack with that. Will also start with the 48 pilot. Real keen to see how it goes

I don’t think you will have to much trouble jetting it, once you find a good baseline. I know some people like the Yamaha dual tapers and others like the Suzuki triple tapers. I guess it depends on what you have or feel more comfortable with.
