94SER Posted March 5, 2016 Report Posted March 5, 2016 I'm going to be running vitos super stock 65mm,fmf fatty gold series with powercore2 and stock airbox k&n w/outerwear and NO lid. I'll be riding in the 500'-900'. What should I start my mains at? What should I set needle at? And i got 27.5 pilots. When I got it last year it had the pipes and filter with lid and vent holes in lid with 25 pilots and 200 mains ran good I thought but only rode it a week before rod bearings went. It would idle last year but tors were broke. One screw missing in one and other screw didn't do anything when turned. Slides were open I enough to make it idle I guess. They will be removed when I put motor back on. Just installed idle screws in carb. Quote

With the mods listed, I would say toss a 30 pilot, needle second from the bottom clip, and a 300ish main. Those Pistons simulate porting to a degree so it will certainly eat a bit more with them.

oldskool Posted March 6, 2016 Report Posted March 6, 2016 I think FMF recommends 30 pilot for their pipes, like trick said start with 300 main. I believe you will end up with less(280/290) so order a few different sizes Quote
Shee_fast Posted March 6, 2016 Report Posted March 6, 2016 What reeds are you using..I would put the clip in the middle..start at 300 main id keep the 27.5 unless your running vforce reeds...I'm at a 290 at 1200asl but I have a lid without the snorkel with fmf fatties only .20 over Sent from my VS810PP using Tapatalk Quote
sleeper06 Posted March 6, 2016 Report Posted March 6, 2016 Better learn how to read plugs I've seen that exAct set up run 68 pilots 162 mains on 34 pj so be careful 2 Quote
94SER Posted March 6, 2016 Author Report Posted March 6, 2016 Stock reeds for now. Is there really any increase in power with lid off vs snorkel removed? I will be trail riding is the only reason I think about keeping it. Quote

I will be trail riding is the only reason I think about keeping it.You letting more air in with the lid off that's why you will need a bigger main...as in power wise I'm not sure you might gain a little but I trail ride myself that's why I just took the snokle off cuz I hit mud and water here and there Sent from my VS810PP using Tapatalk Quote
bluebanshee98 Posted March 7, 2016 Report Posted March 7, 2016 You don't need the lid on the air box. Just have a good filter. Buddy of mine used to fly into deep ass water with no lid on. 1 Quote
