Anybody recommend a set of feeler gauges for the valve check. Looking for a set with very small increments. All the sets I own or see locally make some big jumps and want to really get a near perfect measurement.
Bike is at 54k and hopefully it will be my last time unless I keep it to 100k. I plan to skip the next one unless the bike seems off.Koinz said:You must be good at getting to the valves given your past troubleshooting experience though.
Exactly. This is why you seldom have any flexibility to decide whether you want to be on the loose side or tight side of spec - if a valve is out of spec, there is only one shim that will bring it back to spec and you won't have any ability to put it on the loose side or the tight side.becoyote said:Seems that with the possible error in the reading and having to make .05 jumps it would be pretty difficult to get them all right where you would want them when there is only .06mm difference between tight and loose.
I agree. And I have the same approach for torque wrench. Not that precision is as critical as feeler gauge, but to avoid mistakes or bad conversion (that you find also in Clymer and Haynes BTW).markjenn said:If you're really trying to be precise, I'd get a metric set. There are some significant round-off errors when you take clearances spec'ed in metric, convert them to english (thousands), use english feeler gauges for measurement, then start trying to convert back to metric to spec which metric-based shim to use.

You can use Honda TRX 450R shims(9.48mm) they come in .025 increments. Hot Cams shows the Yamaha and Honda shims to be th same.markjenn said:Exactly.

From the factory, you'll find that installed shims may be in finer than .05mm increments (e.g. a "178" for a 1.78mm shim), but all you can get from Yamaha are .05 increment (e.g., 175 or 180) shims. Perhaps after-market shim kits have smaller increments. Some folks hand sand shims to a desired thickness measured with a micrometer, but I wouldn't be comfortable doing this.
