I installed my toomey's and put in 280's put the stock needle on the 4th clip. T-5's and snorkel removed are my only mod. It's about 30-40 degrees out here. Should I just buy some bigger jets or not. I really wanna ride BAD.

You need to run a plug check to find out. At those temps, a 290 or 300 might be more suited, but I'd at least give it a try, see how she's running. I don't jet with the bike off, I jet with it running, to see the plugs and feel how shee's running.

You should be just fine, especially with the airbox lid on there. At absolute worst you may be a tad lean depending on what your elevation is...but not too lean to where you'd mess anything up. I ran 280 mains with my Toomey's at sea level and the jetting was dead on. Do check your plugs though..... Smart choice on keeping the stock needles! :cheers:

Werd...I ran 280's with my toomeys & still am with my PC's. But it's always best to be safe than sorry if you're really not sure. :cheers:

You should be pretty close to where you need to be, I am running 280's with the clip on the 4th notch. Just do a plug check after wot.

If you're right at sea level, go do a couple WOT passes and check your plugs with the 280's. I wouldn't go up to a 290 before checking your plugs with the 280's first. If the 280's are a little lean, go ahead and slap the 290's in there. My Toomey's didn't like the 290's in the higher RPM's, shee spit and sputtered, ran like shit. I also have the same airbox setup as you do at sea level.

I'd run it. Check the plugs, but I bet your right where you want to be at those temps with the stock filter and lid on. I ran 260 mains down to 50 degrees, sealevel, with FMF's stock filter, lid on, snorkel off and it was just a tad lean, but nowhere near piston melting lean.
