As for the grips, one guy uses any kind of spray paint around to get them on
and glued, another guy uses the type of air needle you would fill a volley
ball with and some air which makes the grips slide on. Of course you would
have to use this technique before cutting the end of the grip off for the
bark buster or like handguard. I like to use the existing grips and have yet
to wear through to the bar, the rectangular raised portions need trimming
after some of them start coming loose.
Aren't you supposed to try and stay away from those 12,000 rpm bursts on a
new piston and ring like on the brand new break in? For what it is worth, I
bought a new husqvarna wr 125 in 1999 and It smoked a lot when I revved it
out at the beginning. I thought it was ruined but it seemed to heal itself
by and by. Eventually I got a new piston from husky (not aftermarket) for
it basically because one of the power valves broke and contacted the piston
but I don't recall it smoking after installing the new piston. But I didn't
hone or re plate. I kind of think the 125 has all the types of power you
would want buts just a little slice or rev band for each kind. Well of
course it doesn't have killer torque down low but my 125 will not cough and
stall it just goes slower with less power. And if you do stall it and have
any kind of forward motion in any gear including first gear just pulling in
the clutch and then releasing re starts the engine. At least with the rear
sprocket I have probably with the original one as well.
