ap cam gear wear

I have the bog when cracking the throttle quickly. I have done lots of searches and reading, which resulted in me switching from a 70 leak to a 50 leak jet, and also did the flex fuel screw at the same time. This made the bike very hard to start, and the bog alot worse, so i took the carb apart and started looking at it.

One thing i have noticed is that the little cam behind the throttle drum, and where the ap rides seems to have grooved into the cam, is this the way they come, or is there a problem with mine?

is this a part that can be ordered?

here is the best pics of it i could get



Haven't had mine out so can't say for sure but from the second picture it does not look right, looks like a groove is worn into the cam.

I agree.

That looks like what happens if you 'saftey wired' the apump linkage (aka o-ring mod, but more radical). They bind when you do that.

You need a new cam.
