RPM ice cube jetting

Recommended Posts

Now before someone jumps down my throat and say's to go check out the stickies, I have and didn't see anything pertaining to jetting the RPM Ice Cube 315 big bore kit for an 03 YZ250F......

I just bought the aforementioned and noticed that the header pipe glows red SOON after starting and in not particularly hot atmospheric conditions either. I figure this means it's running lean on the bottom end, huh? Maybe its something as simple as richening the air fuel mix screw an extra turn but the guy I bought it off said it was jetted for sea-level and I usually ride between 2000-4000 feet above.

Does someone else have experience in this area with this kit and can recommend jet sizes?

Thanks in advance

MM

So I just dug a little deeper and it seems the 'glowing header syndrome' is a common thing on the 250. Well, if its nothing to worry about I guess I'll just go ride!

I'd still be curious to know what other people are jetting their Ice Cube's to tho.......
