Went for a bit of a run on my old dog of an nsr250 mc16 yesterday, about a 100 miles with some mates, all on poncy 600's and my lady on her nc30..
In between parking up and waiting for the rest of them to catch up (seriously..) I was having a little bit of fun with the old smoker on the twisty welsh roads, as one does and aside from the horribly soggy suspension I noticed that she vibes like hell when at high revs, and is generally quite harsh especially when compared to my seized-on-the-way-back-from-the-mot
rgv. Is this right? I had heard they were a bit 'raw' but am quite suprised how much it is.
Think every thing is in order, engine aint moving around and the crank 'sounds' ok from the outside. Whats a crank rebuild cost anyhoo? Are they a costly job?
Thanks
