Ok, my bike never came with the stock muffler. So for the past 2 months, I've been riding around with straight pipes and damn it sounds good. Sounds like a screaming f1 car at high rpms and a growling monster at idle. However, I have stock jetting, which I'm sure I will need to upgrade since I'm running with no muffler. A small note, I have an after market K&N lifetime airfilter on there if it makes any difference. Just wanted to hear from you guys what jetting I should go for. You guys don't have to worry about me getting pulled over We only live once, so whaaateverrrr. Cops never pulled me over, I'm fortunate that I have neighbors with straight piped Harley's They're sympathetic when it comes to stuff like this hehe, well at least on my block...

 

SO - > what's the help question ?

Jets sizes ?

 

i think jet sizes... i have no idea what he needs honestly... i think i'm running 141's..

 

Yes I need jet sizes. Stock jetting isn't cutting it when running with no muffler. Any suggestions towards specific jet sizes? Thanks

 

if you talk to dyno jet and tell em whats done to the bike they'll send you what you need. I did mine through another company on ebay, sent em my specs, and they got me going

 

Rumor has it that just throwing a single spacer under all of your needles does the trick just fine.
