fastbanshee8 Posted June 27, 2010 Report Share Posted June 27, 2010 I'm running the same carbs, on a stock stroke 4 mil, with CPI's, porting, and pods. I'm running a 300 main, and I can't remember what size pilot. I think the 34's are going to be too much carb for your setup. Try some 28mm, or 30mm carbs.

robert0762 Posted June 28, 2010 Report Share Posted June 28, 2010 You don't need plus 4 timing but its a great mod for cheap. Really wakes up the mid range Quote Link to comment Share on other sites More sharing options...

fastbanshee8 Posted June 28, 2010 Report Share Posted June 28, 2010 Pods, are K&N clamp on filters. You use them when you ditch the air box. You really won't need the 34's, until you go to a stroker crank, and in frame drag pipes. Quote Link to comment Share on other sites More sharing options...

fastbanshee8 Posted June 28, 2010 Report Share Posted June 28, 2010 They will probably be tough to get dialed in, since they are really more than you need, but they'll work. I'm not sure where you'll want to start jetting wise. Quote Link to comment Share on other sites More sharing options...

fastbanshee8 Posted June 28, 2010 Report Share Posted June 28, 2010 You'll be over carbed with the 34's, and the 28's, or 30's will work much better, for your mods. Quote Link to comment Share on other sites More sharing options...

pr0blumz Posted June 28, 2010 Report Share Posted June 28, 2010 34s will be fine for your setup. Try 340 mains and do a plug chop. Should do just fine. Quote Link to comment Share on other sites More sharing options...

fastbanshee8 Posted June 28, 2010 Report Share Posted June 28, 2010 The 340 will be way rich for your setup. I'm running a 300, and I've got more motor, CPIs, and porting. Try starting with a 300, and jet down. Quote Link to comment Share on other sites More sharing options...
