banshyeeha Posted September 18, 2004 Report Share Posted September 18, 2004 Hi guys I am based in the UK and new to your great forum. Just had my FMF Fattys and Power Core 2 silencers delivered from the USA - second hand but great condition. My question is that I would like to fit these tommorow and ride but getting hold of jets in the UK is near impossible, I have some 270's ordered but they haven't arrived yet. Temperature tommorow will be approx 15 degrees and I have a completely standard 2000 banshee. Will I be OK to ride my bike tommorow with the standard jets and my new exhaust system or will I blow her up ! When I ride tommorow it would be for say 15 mins and then a break of 15 mins on and off throughout the day, mainly high revving in 2nd and 3rd gears around a small MX track. Any help would be greatly appreciated. Thank you in advance. Quote Link to comment Share on other sites More sharing options...
txblueshee Posted September 18, 2004 Report Share Posted September 18, 2004 It's bad to ride without jetting to start with then... much less pinning it around a mx track. The 270's might be ok for warmer weather (depending on your elevation) assuming you don't have any intake mods. I'm at 800ft., with pro-design intake, reeds and fatty's. I run 310's.

banshyeeha Posted September 18, 2004 Author Report Share Posted September 18, 2004 I dont have the 270's yet, I was going to ride with the standard ones (not sure what standard is) Will it do any damage or will it just not ride well?

Ducman Posted September 19, 2004 Report Share Posted September 19, 2004 I wouldn't run it with the Fatties and stock jetting and it wont hit the band and rev well under a load anyway. (starting and adjusting the air screws is ok) The typical main size that come on a stock banshee are #200s. If you put the pipes on, install the 270 mains, remove the airbox snorkel but leave the air box lid on it should be fine. The stock pilot jets #25's may be a bit small but should work. You will probably want to turn the air screws to within 1 or 1/2 turn of seated (all the way in) to richen up the pilot circut. With small pilots that are running a litle on the lean side, richening the needle (move the clip one or 2 slots away from the blunt end) will help compensate.

00BANSHEE Posted September 19, 2004 Report Share Posted September 19, 2004 Ducman is right on. The Fattys usually ship with a 260 main from FMF. When I put them on and installed the 260 mains I had to remove the snorkle but leave the airbox lid on. It ran perfect. This is at ~1400 elevation.
