Well, first off, our £25 assessment fee covers dismantling the crankshaft down to its individual components, and measuring everything with a micrometer to ensure it's serviceable. I am not prepared to give away the numbers on a public forum. In my opinion, our service is unequalled, and we've never had a rebuilt crankshaft fail. We have rebuilt cranks that circulate the Isle of Man every year. Giving away certain information of ours, gathered over around 20 years of working with NSRs would give away our edge. The diagram in Tech section is straight out of the official Japanese Honda Workshop Manual. I'm afraid you would need to have your crank builder interpret it best he can, if you do not wish to use our services.

If the crank is considered rebuildable, then we will quote for the parts necessary. Main bearings are now £200, not £150, and a "basic" crank rebuild is £275 + bearings + return shipping. A "basic" rebuild is still less than half the cost of a new crank from Honda. (Approx £1150) If the crank is not rebuildable, it will be either returned (in component form) at your own cost, or disposed of. We can supply OEM Honda big-end bearing cages and rollers, and thrust washers. Again, the big-ends and cages are not cheap, but in fairness, almost every crank we have done has not needed big-end bearings doing. Generally the big-end crank pins wear or are damaged before the rollers/cages go out of spec.

Our cranks are trued beyond HRC specifications once rebuilt.

I'm sorry. That is all the information I am prepared to share.
