I just completed my first valve inspection,
I'm pretty sure I did everything correctly...
I noticed when I aligned the timming marks up for the #1 piston, the cams were pointed in towards each other, and pressure was still on the lifter.
So I turned the crank over until they pointed away from each other as directed in the service manual. the # 2 piston was right on with the timming mark, both cams were pointed away from each other.
Has anybody had this issue ?
It is normal for the cams to be in proper position for valve clearance measurement at every 2 rotations of the crankshaft because it's a four stroke engine. Valve train rotates at half the speed of the camshafts.
#2 is in desired position at one revolution (clockwise as seen from right/timing chain side) of the crankshaft after measuring clearances on #1.
I just thinned and switched some shims around, to set all my inlet valves' clearances at 0.18mm, and exhausts at 0.26mm near middle of spec range. I used wet fine emery cloth on a flat wooden table to thin some of my original shims.
You can get 7.48 mm diameter shims (as on Versys) in 0.025 mm increments (instead of only 0.050 mm increments) in 2.50 mm to 3.50 mm thicknesses.
Suzuki 2004-2005 RM-Z250 shims $8.47
Kawasaki 2006-2011 KX-250F shims $8.96
(Versys shims 0.050 mm increments $11.78)
