Nyteknik
Bannad
Kände mig tvungen att delge er denna dråpliga berättelse om killen som lägger ner ett enormt arbete på att modifiera en CR 500 crossmotor att passa i hans NSR 250 gathoj och som slutar i totalt fiasko. Länken längst ner innehåller alla detaljer men omdömet nedan räcker egentligen.
Some quotes from Chris "I got it out for a good ride today and it just does not seem very rideable. It vibrates extremely, extremely bad, and it just did not feel right in the turns. Even when going straight, it will not hold a steady speed, it wants to jerk and kick. It just does not run like it is supposed to be in there. The vibration is just unreal. It feels like I am holding the dang engine in my arms when it is running. Then all of that mass in the crank spinning must be affecting the handling, because it did not feel like it wanted to lean as easily. I think mostly the vibration is scaring me more than anything. I just hate to ride it very fast when it feels like every bolt in it will vibrate out in less than 2 minutes."
So there you go, would Chris recommend this conversion? No!! Sure it can get the front wheel up in third gear, even fourth, but the bike is unrideable. Future plans for this NSR will see Chris rebuild his stock MC21 engine and go with that. New bodywork will eventually be ordered and painted in the same colors plus a few other things that need to be done. The engine, pipe and the parts are all for sale, but he does not believe anybody would want them.
