250-500cc Gearing for single track on WR300

Hey guys i hope im not hijacking the thread to bad but im at 15/48 and i can just about hit 45mph! does that sound right? i thought id get a little more out of her when i changed the front sprocket. btw those trails do look badass

Something is seriously wrong if you can only go 45 with a 15T front sprocket.

Thats what I was thinking. I know my lectron is running rich and I'm having trouble finding the sweet spot

What Eagle free said. You should be able to do 80 or 90 mph with that gearing on a 300. I've pulled over 70 mph with 13:50 on my 300 (and had smoke coming out of the silencer afterward from burning off all the spooge in it). Hee hee.

I also run 13:50 most of the time for tight single track. 14-50 is also great all around. The motor has plenty of pull to still lug and not stall down low and requires less shifting as it spreads out the gearing a little. I used to run 14-50 or 14-48 in the desert without any issues at all.

I should add that I run a Rekluse Z-Start Pro, high comp head, gnarly pipe and the kehin PWK ASII, so plenty of bottom to mid for the 13:50 and 14:50 gearing w/no fear of stalling. It lugs like a tractor (or one of the 4 strokes bikes I've heard about ) when I want it to.

24Valve I just replied to your other thread. Maybe it will be helpful.

The 12 front and 50 rear sprockets arrived the other day from Supersprox. Work's been busy, so no time to try them out yet. I'll start with the 12/48 combo first, then try 13/50, and finally 12/50. I'll have little time to ride before my trip to West Virginia, but I'll eventually post back with my impression with the different cogs on the WR.

Thanks again for all your input.
