Interesting-about CrankWorks. Since I had the bike running for a minute or two I know my crank it's not especially damaged but I would love it to be at it's best.
PE said they would like pictures of my crank before they would commit to working on it- I think it's because two kinds of cranks were installed in the MC18 and they need to know which one, but I haven't got to splitting the cases yet. Paul @ Tyga said that the earlier later MC18 cranks share bearings with the MC21 and MC28 which they sell.
I contacted PJME of Wolverhampton today. I purchased a crank from them for my RD350LC, it's the smoothest running bike I have right now, but they won't do it because they are sure the parts are unavailable.
Not sure which crank I have but if it's an early one PJME recommended Chris Applebee Engineering who can recondition the parts already in the crank....hmm. http://www.applebee.co.uk/
I'm basically looking for anyone familiar with the NSR crankshaft...but might reach out to CrankWorks as you are clearly happy the their work.
On the shock PE came back with replating the shock body and fixings is £75.00, recoating the main spring in a flexi proof paint is £45.00, so with the rebuild of £106 and a guessimate of shipping of £50 for both ways brings it to £276/$380 and into the realms of what a new Hagon would cost.
