A ZTR250 from Hungary

My name is Zoli, an old age pensioner, but young forever
I've a ZTR250 for a years, I've worked continuosly on it, but now work well.
It has a Bashan 250 ccm (quad) engine, not too fast, about 70 Km/h what it likes, max. speed is 90 Km/h.
Next year I try to reduce vibration, because it distubes me.
I thinking about some car's motor stay gum, which suit to frame and engine. Perhaps somebody can help with advice, or somebody has experience in this theme . Now I begining the reading in this great forum
Wide way for everybody!
