definatly got me thinking, i had been reluctant to go too low on the pilot with the new motor, but the air screw probably should be a little more effective. i have the next pilot down i'll give that a run but sounds like i may need lower. The emulsion tube doesn't appear to be to worn but no doubt has some wear given its age, a new one was the plan but couldn't find one.

JohnnyO, Ta for info (re round slide). Do they have a conventional idle mixture adjustment?

Modern fuels are significantly 'lighter' (though they still have higher specific gravities) than old leaded fuel.
The PWK has a major advantage over the PJ and it's not throttle position or the fuel curve. ;)

The non-retarded idle/off idle circuit.

That's still a big pilot, i've gone down from a 58 to a 48 in my '89 250. Try about a 55 and drop the needle another clip position and see how that is.

Right you were, tried your advice before going the gearing option and it worked a treat!
Ended up with a 58 pilot and leaned the needle and the difference is HUGE i knew it should have more but was starting to wonder if thats just the way older 125's were. Now it pulls well off bottom(for a 125) and i'm sure the clutch will last a bit longer as well.

Thanks

also got me thinking about my 84 cr500 which has standard jetting. If the 125 was that far out, how far out is the the 500 which for obvious reasons i haven't had too many concerns about lack of bottom end. do i really want to liven this one up
