250r Performance

[The Nut]

ok I hav a few questions regarding the 250r

Has anyone ever removed the counterbalancer shaft or lightened it to reduce reciporacting weight?


and has anyone ever tried Nitrous and how long would a bottle last and how much HP boost?

I know of people removing them. My 300ex I had to remove the counter balancer, because something on the crankshaft gear was knocking when he had the counter balancer installed. It seems to rev fast, but vibrates alot more then my dads stocker 300ex.
