which after market air filter should I change to. Ialso want to do nyrocs muffler mod.So I need some info on jetting.I ride in wisconsin so we get the big temp change. winter /summer THANKS

 

I run a K&N filter and i have the nyroc exhaust mod , i did no jetting and it runs great .Try to stay as close to nyroc's directions to drilling i myself drilled 9 1/2" holes in mine sounds alot better and seems to give it a little in the bottom , not much if any at all in the top end. another mod you will like is the snorkle mod ,you can either buy the dg snorkle for 50 $ or you caqn go to a napa store and order part# 7335 hose you will have to do a little cutting but with this mod and the K&N filter i have no problem getting my front end in the air even at 15-25 mph before there wasnt a chance. try these mods they are cheap and they help alot.02 650warn 2500napa #7335K&N filterEPI black secondarynyroc exhaust mod

 

You will only have to rejet, if you open up the bottleneck in the air flow through you engine...TRAILRIDE... have you read your plugs ??? I'm suprised that you don't need to rejet with the K&N & the muffler mod... by the way, if you don't have to rejet, you are not making any more power... If your jetting is truely OK, I'll bet if you put the DG snorkle on ( it's huge compared to the stock one ), I'm sure you'd then need to rejet, & would be making much more power ... WAM

 

Well to tell ya the truth jetting kinda scares me . Id hate to get into it and mess it up .ive been to nyrocs site and most everyone says jetting mostly helps starting . ok a question, is it really that hard to rejett or am i just all bumfisseld over nuthing (bumfisseld ha ha ).

 

quite honestly, my intake system is totally custom, & I took mine to a competent shop... but if you can find someone else with similar mods, you'll be amaised at the difference it makes...WAM
