doug Posted May 23, 2009 Author Report Posted May 23, 2009 Yes, running a lid, with no snorkel. +15 to +30 degrees. thanks! bump - anyone? Looking to get this thing running right now. Quote
doug Posted May 23, 2009 Author Report Posted May 23, 2009 bump - anyone? Looking to get this thing running right now. Going to try 240s... Everything else stock. Quote
AKheathen Posted May 23, 2009 Report Posted May 23, 2009 if that's ferinheight, then i would start with 260 and 27.5, celcius, would be 250. how far north is ottowa? i'm @ red dog mine right now, above the arctic circle, and it's 40-60 ferinheight Quote

Switched to 260s and shee's running great! Thanks! Quote
doug Posted May 27, 2009 Author Report Posted May 27, 2009 Somehow, I've got a small bog, opened the air screws up to 2.5 turns - is this bad? Should I be dropping to 250s? Thanks. tried 240's, seemed a little lean. Switched to 260s and shee's running great! Thanks! Quote
mopar1rules Posted May 27, 2009 Report Posted May 27, 2009 is the bog on the bottom, coming off of idle, or on take off? is the bog @ midrange or top end? what? Quote
AKheathen Posted May 28, 2009 Report Posted May 28, 2009 like i said earlier, you probably need 27.5 pilots, but your airscrews are out kind of far. is that where it idles the highest when warmed up? what clip is the needle? also, same q's as mopar1 Quote
doug Posted May 30, 2009 Author Report Posted May 30, 2009 (edited) The bog is at an idle, when I give the bike a quick shot of gas. Took the air box lid off and same problem. If I hold it at around 2000rpm and then crack it, it backfires. Seems as though it's getting too much fuel. Needle is at stock position. Runs fine through the gears. Would moving up to 27.5 pilots not give it more fuel? Might take the boost bottle of, but I would think that would be giving it more air, not taking away from. Have read mixed reviews on these things though. Thanks. Edited May 30, 2009 by doug Quote
mopar1rules Posted May 30, 2009 Report Posted May 30, 2009 turn your air screws in to like 1 turn from closed. i think you stated that you were @ 2-1/2 turns out? try the air screws @ 1 turn out, but i think you will end up needing 27.5 pilots and 1-1/2 turns out on air screws. Quote
AKheathen Posted May 30, 2009 Report Posted May 30, 2009 x2, those pipes usually like bigger pilots, and the boost bottle likes a little more on the pilots, too. not gonna say a lick on boost bottle function, but they are notorious for not being spaced right, and tearing the intakes, causing an airleak. a backfire like you described could be caused by that verry airleak. i would check for that first thing, so you can tune it without an airleak.

doug Posted May 30, 2009 Author Report Posted May 30, 2009 OK guys, I did the follow as per your instruction: 1) Turn the air screw out 1 turn from being all the way in. (this really confused me as I had thought it would cause a greater bog, instead it help take it away - not completely, but definitely helped. Weird. What am I missing?) 2) Took the boost bottle off and carefully inspected the rubber. Everything appears fine. I replaced the boost bottle with the original cross-over pipe. Also, the backfire appears to be gone, but the bike does seem to be running a little lean when revving. Sound right? Hence the instruction to install 27.5 pilots? Thank you!!!!!!!!!!!!!!!!! Quote

Update - no damn 27.5 pilots, will order on Monday. I have 30's, but this is prolly too big? Quote
