Where do you uk riders get your shim kits?
not sure bud, first time I have actually had to change them, however when a garage takes in bikes as trade-ins they will need to service them so would imagine that they will possibly have shim sizes for all different sorts of manufacturers and models.Makes sense - especially if only 1 is outside range for instance. They're readily available as a rule?
Got into it today and checked the clearances. All within spec, but one inlet is 0.08mm and one exhaust 0.13, so right on the bottom limit. The others are smack in the middle of their range.
As I've gone this far, it makes sense to adjust those that are getting tight, but as I'm going to have to lift the cams and get a pair of fresh shims anyway, does a sensible person take them all back to max permissible clearance while they're about it?
For your information. It has a official position of KTM R&D.But before I go too far with this, I'm gonna plant something right out front. The 2016 and 2017 rep manuals call out .08 - .12mm on the intake and .13 - .17mm on the exhaust; whereas, the 2018 rep manual calls out .10 - .15mm on the intake and .15 - .20mm on the exhaust. Hmmm... it'd been 8-12 and 13-17 all the way from 2013, according to documentation... then they finally widened it on the 18 and 19 models... Ok, enuffa that.
Believe or not the clearance will become tighter with time. There is a wear but it's easily compensate by metal expansion.My question is should I go over by 0.02 and let it wear in over the next 4000 miles? Or stay with what I've got and check it again in say 1000 miles?
I'd rather not have to check it again so soon as I'm sure you can understand!
