With a drag port, your gonna need a 35-40mm carb. Call K&T and see what they suggest for your setup. They'll beable to get you close on your intial jetting with carbs their familiar with. Quote

I would contact K&T and see what they say. I'm sure they'll say you'd be better off running 35's or so. Quote
bansheemandan Posted February 4, 2011 Author Report Posted February 4, 2011 what kind of horse power do you think this setup will make Quote
jbooker82 Posted February 4, 2011 Report Posted February 4, 2011 Yea probably 35's if your running a drag ported 4mill down the track. If your just doing general riding then I would go pwk33's but I also wouldnt run a drag ported stock cylinder 4mill. A drag ported 4mill isnt a whole lot of fun for any thing but wide open duning and drag racing. I tried a drag ported 4mill and in the trails it wasn't much fun. Quote

I love drag ported cylinders. it teaches you to ride a banshee the way they were ment to be ridden. WFO! lol I have a set of 34 pjs with brand spankin' new K&Ns and outerwears. pm me and I'll give you a price! Edited February 5, 2011 by Josh Z Quote
jbooker82 Posted February 5, 2011 Report Posted February 5, 2011 That maybe the case for guys who have wide open areas. Get in the trees on some trails and see how you like a drag ported stock cylinder. I am just saying don't get all caught up in hp numbers. I would go pwk 35's at the minimum. Quote
