I just bought a restored 1974 Honda CR250M Elsinore. Now I need to buy a
new right foot. The kick starter on this thing has reared up and bit me
so many times in the last couple hours, I may never walk the same again.
Is there a trick to starting these things?
I've been told the timing may be off a bit, but don't have a spark plug
hole dial indicator to correctly set the timing. Could it be the timing,
or is it something else?
Point gap is correct at .012 and look to be new. Spark plug is fine. All
electrical connections look sound.
It does have a high compression Wiseco piston, so maybe I just have to
learn to live with this? Damn, I need to get some boots with a steel
shank in them.

I'm not a guru, but two out of three isn't bad.
I had a '67 or '68 two-cylinder TC200 Suzuki back in the early 70s. It
had an oil injection system so I didn't have to mix oil. With my bike,
removing the points cover also exposed the static timing mark. The
rotating mark would appear through a little hole when it got close to the
static mark. I'd place a 12 volt test light across the points, line up
the timing marks, adjust the points plate till the points just opened,
then I'd check it by rotating the engine to see that the points opened
(test light lit up) just as the marks met.
It sounds like it must be firing if it's kicking back on you. Since it's
a two stroke, each compression is one that will fire, so as you probably
know you should relatively gently use the kickstart to get the piston up
against the compression, then give it a strong kick that follows through
the entire range of the kick start stroke. Similar to swinging an axe or
a bat, you follow through. That should help keep the kick start from
kicking back.
If yours is a single cylinder, then your piston is quite a bit bigger than
mine was. Perhaps you might want to retard the timing just a bit so it
doesn't kick back so hard? You might want to pull the plug to make sure
you've got spark, too.
For fuel, I pretty much always had to use the choke unless it was up to
temp.
Best of luck.
