If you aint done it before then i would get it done by a garage . Iv done the valves and re shimmed my crossers but i don't fancy doing the blade being an inline 4 compared the CRF's single lol
If your decent enough with the spanners then give it a go. There's plenty of time through the winter months to get the info u need.
I've got the full workshop manual that my mate got for me. It might b the same 1 as Dan's talking about. It's on cd so it's ideal to take the laptop into the garage to look things up if need b.
I was meant to have mine done about 4000 miles ago. I'm decent with a spanner too, but I'm giving mine to Holeshot Racing (Jack Frost if anyone knows him) and getting a custom map done at the same time. Last thing you'll want is to drop a shim or set the timing off a tooth.
In that case scrap that manual .. They are easy to find on line thou . I agree with Viper thou . Get the timing wrong and you could put a piston through the head
Checking valves clearences is not a daunting task to any serious DIY mechanic accessing is the problem. The carb blades are a peice of cake, the injector blades are compacted and cam retainers are located in radial fashion unlike across on the carbed version making the task more difficult. However have only come across one blade that needed all 16 valves shimmed which I beleive to be a factory cock up.
Might be wrong here but how many bikes shims would actually be out (a lot) after 16k? My guess is not many at all.
ive never known any modern bike need 16 shims doing, most i ever did was 2 on a high mileage sp1 & 5 on a doggy R1
Ive checked around 30 rr8+ at both main service int's none needed any shims.. Posted on my HTC Sensation with Tapatalk
No problem.. Get this: around me I have three or four main bike dealers I keep three full shim sets all cost around 300.00 each for the sets of shims, sometimes my stocks of say one shim run out so often I have to call around to get said shim, the dealers round me do not keep any shims in the workshops? Odd hey.. Sometimes I wonder if they even bother to look at them... Posted on my HTC Sensation with Tapatalk
It's not a difficult job and following the instructions is easy, gaining access was my biggest problem. Best advice is take loads if photos whilst stripping down, tag anything you remove and put your own proof marks on for lining all the cams and sprockets back up. If you take your time do things methodically and follow the instructions its really quite a straight forward job.
