Thanks Huski. Bike has Peter Schoene motor. Nice flexible spread of power with a bit up top.My son has a Yamaha WR250 and there's nothing between them in a straight line. First time I rode it "handling" awful. No brakes, tyres too hard, rear shocks way too hard me trying too hard and to be honest I was pretty dissapointed. However next time round correct tyre pressures,taller seat,Yamaha foot pegs (stolen from my son's bike!) modern bars, softer rear shocks and lighter fork oil in conjunction with YSS fork valves made all the difference. Brakes still average at best. My riding skill still very average at best. Still to come a Mikuni, improved air box, Titanium frame and carbon fibre guards! Cheers Jerry
