Edit: How much work do you have to do to squeeze just under 75RWHP out of an NSR!?

Erm, quite a lot. That's 3 bhp more than a stock 1992 NF5 RS makes!

A more realistic figure for an NSR running stock crank, modded cases, ported barrels and optimal compression might be very high 60's bhp.

Other questions;

I've never heard of an NSR gearbox problem, it's very similar to an RS box, the crank is good too but needs someone who really knows what they're doing to rebuild it and the bearings are hard to get.

You can get pressurised airboxes for the NSR, Gecko Racing (on this forum) has made some very good replica's of ther JHA ones made.

The NSR in F3 type form is heaven to work on next to an RGV, no airbox, no oil pump, no carb solenoid plumbing etc. and of course all NSR's have their carbs attched to each other to the rear of the top barrel like this and they come off togeather.
A main jet change is about a 15 minute job in total. Top barrel (the awkward one) takes an hour at the most.
