'03 RM250 Woods set-up

[2-Strokes 4-ever]

Hey, hey. First time on this sight, very cool!
Thru the years I have owned all brands of Japanese bikes. But found a home with Suzuki...just love the way they handle! Thought I'd let some of you know my experience with motor mods. only, since suspension is a personal preference. Don't race much anymore, but my old crusty enduro buddies and I still get together to find the tightest, ugliest woods riding we can. After playing with the powervalve adjuster and adding flywheel to my RM, the "hit" was still too much. Varner Motorsports knows what they're talking about. They told me that even the Suzuki GNCC hot dogs have to have the power broadened out. With their cylinder, head work the V-Force reed valve...she's a whole different animal. (Varner does Suzuki GNCC's work.) I also added Yamaha's YZ250 reed spacer. (bolts right on and does more to lengthen the power.) Now, in situations where I need to ride a gear high, it lugs right along with great torque. And a downshift or slip of the clutch brings on the all-mighty roost...when needed. No loss of power at all, maybe even MORE...just WAY more friendly!! Oh, let's not forget the FMF "Q" muffler...if we don't quiet 'em down we'll be walking...

Any idea what your jetting specs are?......I have an '02 and can't seem to quite jet out the spooge. Currently, I'm 165main 45slow and 2nd clip position.

Does the FMF Q silencer really quiet it down?Power still good?Did you use an FMF pipe or just the silencer?

Thanks

Guys,
The '02 is a totally different cylinder, try FMF's site for jetting specs...I wouldn't know how to guess.
The FMF Q is a little quieter and a spark arrester. It may have taken a little top end away, but it's hard to tell. I had an FMF Gnarly pipe, but it made the bike ping. Most aftermarket pipes increse compression. I've heard from more than one source to keep the stock pipe, it runs best that way...and it does. Enjoy!

The reed spacer--Yamaha parts has a reed spacer that fits inside the cage and a 5mm plate that spaces the cage out from the cylinder.Which did you use?

Thanks

The 5mm one. Get 5mm longer bolts too. You WILL feel a diference.

I have an 01 and I haven't been able to eliminate my spooge problems either.
