IrideA250R Posted February 22, 2008 Report Share Posted February 22, 2008 I would run 35mm Keihin PWK's Quote Link to comment Share on other sites More sharing options...
jbooker82 Posted February 22, 2008 Report Share Posted February 22, 2008 What type of porting? drag PWK 35's. Dune PWK 33's. Play / Trail PWK 28's or stock carbs. Drag or Dune port will run 10x better with CPI Pipes. Quote Link to comment Share on other sites More sharing options...

I dont think you're reading that back right. I dont see how a boring would effect transfer ports that you are going to change anyway when porting. To the OP. You should try some 30m OKO's. Its a kehien(sp?) knock off. Very good carb IMO. I would also go with DMC 916's in stead of the Aliens. Just my opinion. I think the 916 setup looks better and sounds better.

He read it right. 66.5 is the biggest you can go on STOCK cylinders, if this guy is running 68mm big bore, he is getting the cylinders resleeved. And he's right...on stock cylinders, that really cramps the transfers..... He's not just boring, it's new (bigger) sleeves as well! Quote Link to comment Share on other sites More sharing options...
