Ok this is so cool...ever since I found how nice the power characteristics were, added to the fact they retain center & side stands, I've wanted another set of J&R Expansion Chambers of my nearly stock RD350B. After searching for nearly a decade, I found a used set in decent shape for $250 on evilBay through Moto Carerra. In the past Doug (owner) had problems with spotty customer service and it was difficult for him, being in poor health in a wheelchair, etc., so I always wanted to give him the benefit of the doubt...well he came through & today I got my J&R's. Like any used 30+ year old set of pipes they have some dings (as described) but no major dents to impede performance. Just have to re-weld and gusset the mounting tabs a bit and they'll be ready to go on...tax time can't get here soon enough, because concurrent to finishing my blue Cafe Racer I'll be working on this bike too..I hope to get a nice GFTP cafe seat cowl for it also. Oh man, this bike is gonna be an absolute blast this summer!
