If you plan on racing with the VRRA, and want to be competitive; get an RD400.
The class structure puts your RD350 up against TZ350s.

That's weird they would do that. I was looking for an RD400 but wasn't having any luck in my financial bracket. Maybe if I come across a basket case I'll snatch one up while I work on this one. could make the 350 a street/track bike and grab a 400 to race. We'll see what happens as time allows but I look forward to the knowledge you guys have here. pretty impressive stuff.

No Glen, that is a bummer.

I've hit a few of those walls in cars, they aren't any fun, even with a car around you. It makes a lot of sense when I think about it.

Speaking of rear shocks, Chris ^ does a few mods on RFY shocks to make them perform well.

Are these swingarms legal in vintage racing? sounds like from what I've read online, the stock RD swingers are a bit weak and flex too much. by the sounds of this VRRA rule, it needs to be of "original style". but the last sentence "Replicas of period swingarms are permitted" and that swingarm on Oilypipes website is a DG replica from the times.

If you plan on running VRRA middleweight production, the only class an RD has a chance in, the swingarm has to be steel... and no reservoirs on shocks.
