What are the advantages to getting a 38mm air stryker over the stock carb? will an air stryker help me? All i have is aftermarket pipe, K&N and Boyesen rad valve and bored 20 over. 1986 motor. THANKS!!!!

 

38 run good on 250's. i run mine on my mild port ad it seems to have smoothed the powerband out nicely. its definitely worth the money i spent on it. ill be upgrading to a 39 so my 38 will be for sell in the coming months if you're interested. its probably tasted 4-5 trips worth of gas so far and performed flawlessly.

 

The larger carb will help with your top-end performance. At 38mm it won't have too much effect on bottom-end. The larger the carb (usually, if you don't go too big) the better top-end at sacrifice of bottom-end.

 

I also don't see any benefit to going to a 38mm air stryker if the 250R is not really modified.
A bigger bore carb will usually cause you to lose some bottom end in place of gaining top end.

If I remember correctly, the air stryker was originally designed to be an anti-gravity carb (read that as for people who are airborne a lot) so that flow was not compromised, but I don't remember the specifics of it all.

Spend that 200 bucks on a port job, and compression increase and I think you will be a lot happier with the (noticeable) results.

 

i agree and disagree. youll need the bigger carb sooner or later, but yes, youll see a bigger result with porting first. 200 bucks IMO isnt that much money in this game.

 

Well i went down to duncan racing and talked to them about a carb. He said i should go with a 36mm pj instead. I went ahead and got the carb, and they took down a bunh of info for me and jetted it right there! I installed the carb and i am now thinking something was horribly wrong with the old one because the difference is night and day...Its like a whole new bike now!! He also said that the 36 would be enough carb if i decide to get porting.

 

Sweet!
