Alright I went out to Northern Tool and picked up another set of feelers to see if I can find one thin enough.
ARGHHH!
Why is it that Yama decided that the valve clearance spec is .11 to .15mm when the smallest feeler I can find is .152mm thick.
So what do you guys (and you few gals) use? and where can I get one?
I know some of you like to use Inches, but that conversion stuff hurts my brain. The manual has the chart/formula in mm, the shims are in mm and my gauges also read in mm. That makes it simple for me.
I know I need to reshim, but without having somewhat accurate initial readings, I have no idea how many sizes to go down.
For example, on 3 of 4 of my intakes I know I'm <.15mm and have 265's in there, so, should I put 260's in there and see where I'm at?
I haven't researched the local dealers to see if they'll swap out shims yet and don't want to spend a whole lot on shims that might not be the right thickness. Plus I don't want the bike down for more than a weekend.
Any ideas on why the 78/79 intake specs are bigger?
Could it be because of the different valve sizes?
Or is it just a noise issue?
Could I open my 80s' intakes up to 0.16-0.2mm?
Duh, I just had an idea. Ask TC if he's got some small feelers. I could swing by his house on a friday, do the shims over the weekend and drop the feelers back off on monday.
Any of you have ideas on how to get shims out of the buckets?
Last time I had the cams out to check which shims I have, one of them wouldn't come out of the bucket. It would spin just fine in the bucket, but I couldn't even get a knife blade under it to pry it out. The magnet I had didn't help either. Maybe use some carb cleaner to break up the oil suction that sucker has?
I know this is a long post, but this is about the only thing on my bike that has sort of been postponed the longest. I've been putting it off too long now (haven't ever reshimmed since I got the bike 8 yrs ago) and I need to get 'er done before it's too late.

), the same as the 'step' in the feelers and the allowable adjustment range. So if you check for .008-.010" and that size feeler won't fit, try the .006-.008" feeler; if the .006" part won't go, go down again, but if it does fit you know your clearance is more than .006" so changing one shim size thinner will increase the clearance to over .008", back in 'range'.
No conversion involved and once I have my clearances numbers I can chose the closest shim (in increments of 0.05mm) that get be back into the optimum range.
