Ive looked through your forum in the past as a guest and found some useful info, now im in need of more specific answers, so thought i should at least join.
Been spinning spanners for myself a few years now and Ive been given a WR450 as payment for a job that the owner couldnt afford.
Its a head scratcher for me, as I needed to split the box to find out why it was stuck in gear.
Dropped the clutch and spark plug out to trouble shoot...very very hard to turn over via kick starter. trying to get it on TDC was a mission.
Cracked the stator off and found a wadded up "shim" of thin metal that had lodged against the rotor and was causing the hard turnover. When that was cleared, the crask assy turned nicely.
Split the case and found all sorts of amazing things. firstly the oil pickup was clogged solid with bits of hard rubber and topping it all off was a three inch length of bike inner tube. The gearbox is a mess with number three pinion gear with a sheared tooth which jammed against number three primary, and number 2 welded solid to the output shaft. various bearings feeling notchy and myself wondering how far into this im willing to get.
My troubles are starting when trying to establish the age of the bike so that I can start putting a shopping list together for the gears and bearings and shaft required.
The headstock has been damaged in the past, with the VIN stamp now illegible bar the last three digits. No other stickers are anywhere to be found and Ive gone over every square inch of the frame just in case it has been restamped.
My question is, how do I accurately order quite a few hundred dollars worth of parts, when I have no idea of year model.
Ive asked my local stealership if they could work backwards from the engine number but they are as unhelpful as ever.
Any of you gents have any ideas?
