Sandking Posted September 13, 2015 Report Share Posted September 13, 2015 Can't go wrong with either one. I've used Herr a couple of times and zero complaints. Quote Link to comment Share on other sites More sharing options...
Dunatic619 Posted September 13, 2015 Report Share Posted September 13, 2015 Same as above ^^. HJR just built me a 4ml aggressive mx port. But I'm local to HJR. So I can drop off and chop it up with Kevin. Quote Link to comment Share on other sites More sharing options...
snowmobra Posted September 13, 2015 Author Report Share Posted September 13, 2015 Cool. So what carbs should used my stock carbs or get 28m carbs. Can my stock carbs handle the power. If so what jet size would I need.I live in Lancaster pa. Rite now I have 4mil crank that I'm putting in BUILT cross tube intake pump 93 gas and 40-1gas and go to run +4 TIME.

trickedcarbine Posted September 13, 2015 Report Share Posted September 13, 2015 Your stock carbs are totally fine on that set up. Ride it for a bit and take a mental note of how much you find your self needing top end charge. If it's just occasional, maybe bore the stockers or if you got cash find some 28mm PWK's. If you suddenly want way more upper end charge you may wanna consider something larger as well as possible pipe swap. Quote Link to comment Share on other sites More sharing options...
tfaith08 Posted September 14, 2015 Report Share Posted September 14, 2015 Don't forget about Redline. Quote Link to comment Share on other sites More sharing options...
mike0chek Posted September 15, 2015 Report Share Posted September 15, 2015 run the stocks until you want more power, than maybe put some real nice pipes and larger carbs Quote Link to comment Share on other sites More sharing options...
Lowroll Posted September 16, 2015 Report Share Posted September 16, 2015 Kevin ported my stock cylinders on my 4mil, they look great and he had them done in half the time he originally thought. I also went all in and got 35mm pwks on my setup and man does it get down. Hoping to get up with SurfJag for a dyno session one day and see what it puts down Quote Link to comment Share on other sites More sharing options...

donkeypuncher Posted September 17, 2015 Report Share Posted September 17, 2015 I've had two sets of cylinders ported by Kevin (HJR) with great results. His turnaround time is second to none. You can't go wrong with either performance wise. Give both a call, tell them what you're lookin for in a motor and go from there. Quote Link to comment Share on other sites More sharing options...
