KDX220 update + question

[JZ05220r]

Some of you might remember all the trial and error I went through trying to get my 220 running how I wanted. I ended up redoing the top end again, and it’s back to a full 220 setup: stock internals, carbon reeds, and an FMF desert pipe. Since spring, I’ve actually been able to enjoy the bike, and it’s been running great with just some minor tweaks here and there.

One recent change was dropping the pilot jet from a 42 to a 40. That seemed to clean up the low-end throttle response I used to get these little hiccups during part-throttle acceleration that felt like it was running a bit rich. The 42 also tended to load up more at idle and would dip faster if I let it sit too long. The 40 definitely seemed to have helped (not completely) in both areas to the point where I am fully satisfied.

With the airbox snorkel removed and still using the stock 33mm carb, does this jetting still sound like I’m in a safe range? Thanks

I would say you're good. What truly matters is how it runs. Also, if your air screw is between 1 and 2 full turns out then you're spot on.

For comparison, I run a 38pj and my lowest altitude is 1600ft asl up to about 2500ft.

Thanks, just needed some reassurance
