The Kaster KAS3085 set looks like a good one. Eleven angled blades in a nice assortment from 0.004 to 0.014 inch in 0.001 inch increments. We need feelers from about 0.004 to 0.009 inch for the KLX250 valve adjustment. Many of the sets I have looked at have a limited number of blades in this range.

Amazon price about $22.



Motion Pro also makes a set with 0.002, 0.003, 0.004, 0.005, 0.006 and 0.008 that would work nicely for about the same price.

 

In a side note, when working in the shop doing set up work I learned something that may be of value too.

It is best to do clearance measurement on both valves at the same time, especially on a bike with forked rocker arms. It is possible to tilt the rocker or cam in the direction of the valve without shim stock in it. This is critical if one clearances the valves close to the tight side. Honda found on the forked rocker (early V-4 and numerous other engines) that it was possible to have a few thousandths pinch if adjusted one at a time, the rocker arm would tilt that far based on shaft clearance. In other words a valve clearanced at .006 alone might drop to .003 when the other valve is checked at the same time. So you end up with both valves too tight when doing one at a time.

The guys bought shim strip material from the Mac tool guy, cutting it down into pieces so they could check and adjust both valves at the same time, holding the shim stock in a Y between their fingers to try to get the same feel when checking.

Is this true with 4 valve OHC bucket set ups? I don't know for sure, but the cam could actually tilt a bit side to side based on journal clearance. So I check my valves with shim stock in both sides. Of course I clearance to the middle value to avoid tight or loose valves and I try to shim to the same value.

 

Thanks for that, Mark. With the set of feelers listed above, it could very well be possible to check both at the same time, or at the least get a feel for if there is a difference as you describe. With my current set, there is no way to do this.

 

Like I said, not positive it is a necessity on the bucket set up, but definitely should be done on any forked rocker set up.
