hoppedupandcutdown Posted January 27, 2017 Report Share Posted January 27, 2017 What jets are in it now? What makes you say it isn't running right? Quote Link to comment Share on other sites More sharing options...
Zachaweia17 Posted January 27, 2017 Author Report Share Posted January 27, 2017 What jets are in it now? What makes you say it isn't running right? I don't know what jets are in it now. I have never heard it run before but the SuperStock pistons say it needs to be rejetted. Quote Link to comment Share on other sites More sharing options...
Ducman Posted January 27, 2017 Report Share Posted January 27, 2017 I don't know what jets are in it now. I have never heard it run before but the SuperStock pistons say it needs to be rejetted. I cant remember what the stock jetting is, but the only thing you listed that would require a larger main jet is the K&N filter, probably one or 2 sizes larger. You can probably use the stock pilot jets, you may need to make the idle mixture a little richer with the air fuel screws, try one turn out from seated. Pistons wont change the jetting. Your oil mix ratio sounds a little on the rich side too, I would mix about 40:1. Quote Link to comment Share on other sites More sharing options...
bigweav81 Posted January 27, 2017 Report Share Posted January 27, 2017 Vito says that because the piston has been cut to somewhat mimic the exhaust port being raised. I ran those once, and rode a trail ported banshee from a guy that was riding in the area......went home, and broke it down, and sold them cheap.

I'm not saying they are junk. I'm saying if your really looking for more power then go with an actual port job Ronnie Dobbs Sent from my SM-S820L using Tapatalk Quote Link to comment Share on other sites More sharing options...
sleeper06 Posted January 28, 2017 Report Share Posted January 28, 2017 For some reason every time I've jetted a motor with those pistons they wanted more fuel than I would think but being you have stock pipes is kinda different I would start high n work down 260-280 and work down Quote Link to comment Share on other sites More sharing options...

bigweav81 Posted January 29, 2017 Report Share Posted January 29, 2017 To be honest....I've never ran, or dealt with a stock exhaust set up. I'd look into a cheap set of fmf, or t5s. I'm not sure what you're after, but a pipe change would be a bigger improvement then those pistons. I'd say pilot is probably ok at 25. Main maybe start at 260, and work down until you find the sweet spot.....again I'm just guessing.
