Belray and Maxima FFT are traditional petroleum based oils. They require a solvent soak, followed by several soapy water baths. I use white 2.5 gallon buckets. One contains 1.5 gallons of diesel fuel, which I use for a 10 minute soak. The other I use ... more »

We are really spoiled with well watered sand/clay loam tracks here in North Texas.

Agreed. Looks kind of odd without the shrouds, and a little too much red for my tastes. Cool bike though.

Glad to help. As far as extended service intervals go, the only time I had dirt pass through a filter was with no-toil. That particular situation was with a bike that sat for about 6 weeks before riding all day on a bone dry sand track. When I took the ... more »

After servicing filters for 40 years, I've come to the conclusion that it's best to just go ahead and remove the subframe and airbox every time you service the air filter. This allows you to clean everything like the factory mechanics do it. For airbox ... more »

DID 520VT2 with Ironman sprockets. That combo will outlast the rest of the bike.
Added reply in a thread Ways to Make the '02-up CR250 Faster 7/17/2014 10:17 AM
I'd like to see those dyno curves. I really doubt that it was +7hp at peak. My guess is it was +7hp lower in the curve. Mine certainly feels that way compared to stock. The stock 05-07 CR250 puts out almost 50hp, but it has no low so it feels like a ... more »

Added reply in a thread Ways to Make the '02-up CR250 Faster 7/17/2014 6:29 AM
I know the 05-07 CR250 makes big, but manageable, power with just the base of the cylinder milled .030" and the addition of a '00-up YZ250 carb. If you leave the head stock, the cranking pressure gets bumped up to around 240psi. That means a race gas, ... more »

The 05-07 CR250 is borderline with pump gas. When mine was stock, I ran straight 100LL. It's only $1.50 more than pump gas, and you won't have to worry about detonation issues.

There is a reason I never ride other peoples' bikes.
Added reply in a thread Best Fuel to use? 7/2/2014 7:53 AM
100LL is the best bang for the buck if your bike needs leaded fuel to stay out of detonation. It's what I run in all my 2-strokes, with the exception of my modified 07 CR250, which has high enough compression to need 30% C12 added to the 100LL.
