Very cool. The bikes, the stories and the racing. I got to visit Europe a few times for work in the early 00s and was always in awe of the motocross magazines with the different products you have over what we had in the states. Needless to say I would ... more »

Added reply in a thread 2007 RM250 PC Platinum vs. Bill's pipe any actual experience? 4/28/2021 9:41 AM

You want an FMF Gnarly pipe to improve low/mid. Both those are more mid/top pipes.

Just wanted to bring this topic back up as I just dropped 2 bikes worth of Cagiva WMX hardware off at the post office to have ROP plate in yellow zinc. Most of the Cagiva hardware is yellow zinc so I'm just going to get it all done. I thought to add ... more »

That's a bummer on the shock seal head. That looks like a All Balls/Tusk/MSR generic seal head. I tend to look at RaceTech site as they have a downloadable spreadsheet with all the dimensions of various fork/shock components. The 84 RM500 seal head they ... more »

One trick to get more bottom and top performance out of those drum powervalve motors is to raise the port at full open by removing material and then remove some of the closed stopper position on the valve and stop drum to get it back to stock or lower. ... more »

IMO no history, no fancy parts, maybe it is a $3000-$3500 bike to most folks or $4K to someone who wants one bad. Prices are crazy and it is definitely a sellers market but that still seems pretty high.

1983 YZ490, 83/84 IT490, 83-86 TT600 top clamps are all rubber mounted and the right width. It has to be a drum brake bike to get the width correct. The disk brake clamps would need an upper and lower clamp and the wheel won't be on center due to the ... more »

The case reed motor of the 89-95 RM motors left a lot on the table that didn't take much porting to improve everything. My buddy had a 93 RM250 that was reworked by Moto Tassinari and it was a rocket ship! Pipes help a lot and Dynoport makes a great

Sandman did you do any prep to these before send them out and is there limit on what a "small batch" is. Have a bikes worth of hardware I'd like to get done.

Yes that is how a leading shoe drum brake works. The force vector generated by the friction pulls the shoe into the drum for a harder bit. That said shoe contact patch actually is less relevant in braking force and is more relevant to heat dissipation,

One thing nice about building old Suzukis is they still sell a lot of parts and there is a lot of used nice aftermarket parts still available. Looks like someone put a profab chain tensioner on it too.

They are definitely on the smaller size for a full size bike which should be good for smaller riders. At 6' 3" and over 230 lbs it was like racing an 85/100 sized bike and lots of clutch work to keep it on the pipe but quite a hoot to ride! Looking forward ... more »

You should have access to the stacker program as part of the GV purchase. Or a sheet in the paperwork that talks about selecting what stack to build. That said I've found most Novice riders like the dual stage setup over a single stage. Gives some plushness ... more »

New DG pipes are crap. I've torn through 3 over the last 4 years racing. They are a pita to jet too. Shop queen or not ridden much is really all they are good for. IMO

Dynoport in PA will build you a pipe.
