setting timing on 250?

[amartina75]

The problem is, with the dial gauge probe in the cylinder, the piston comes up, hits the probe, and locks the engine solid. Reasonably large amounts of force, thru the kick-starter, won't move it. So I don't know if it's at TDC.

you will find it very difficult to get to exactly TDC by using the kick starter. put the bike in high gear, rotate the rear wheel or depending on how you have your degree wheel bolted to the crank use a wrench on the bolt and rotate the crank directly.

____ Indeed so ! _ Next to impossible even.



" put the bike in high gear, rotate the rear wheel "

____ There's certainly a better chance that way, but the trans has too much slop to make that method very easy to adjust for dialing-in to TDC !

____ That's still better yet, however an ordinary "wrench" doesn't hold the bolt-head tightly enough, so rather use a 'vice-grip' to grab & hold the bolt. _ Or best-of-all, if ya have the degree-wheel secured adequately, then simply use IT to turn & adjust the crankshaft & TDC.position !
