Talking of cranks.. i am just in the process of removing mine for a rebuild following a suspected crank siezure.... I'm thinking of buying the bearings and having the crank rebuilt by a local guy who has built plenty of cranks although not NSR's. However I have also looked on the Tyga website and they sell a replacement bottom end kit which includes a new crank. Its a bit pricy at £550 but by the time you have bought all the seals bearings, new rods and paid for the rebuild there might not be much in it.... the question I have is... the part number for the new crank is 13000-KV3-950 but this number doesn't show up on the parts list on this forum..... the number against my model (NSR250R9N) is 13000-KV3-900, can anybody shed any light ?...thanks.
