Question Help...Pinging

Yes, I read jetting 101

I just put a Mikuni HSR 42 on. I was running WAY too rich with my CV. I changed the plugs and ran about 120 miles Sunday and here's what I found. Plugs are clean as a whistle...no marks or colorization at all. The metal still looks like metal, porcellin, too.

The bike really runs great with no backfiring or carbfarting. The only thing is a very slight ping when I do a WOT roll-on from about 3,000 rpm. It doesn't lug at all. It starts going strong for about 500 rpm and then just a few scattered pings the rest of the way up. It really hauls ass, though.

I haven't touched the out of the box settings except the idle. Does this sound like I should raise the needle or...?

If so, how the hell do you do that? I have bigger main jets that came with it and they're easier to change.

Thoughts?

Sounds like the timing is a tad to advanced.

If the timing doesn't help and the pinging is only at wide open throttle you might try increasing the main jet one size.

I'd agree, might be just a tad lean at WOT.

I just did same mod ...my end settings are 1 size bigger on main jet.. needle, moved clip to raise 1 needle 1 notch ...runs great plugs look perfect but its only been in the 50's here I'm thinking I might have to lean it out once summer gets here . You might be spot on with your settings once it warms up ..hope this helps


p.s. they made a really good " mikuni sticky " I must have read it 20 times

Read that sticky alot, too. Basically, I'm waiting for my NRHS top end to get here. I'm worried that if I'm a bit lean now, with 94 octane gas and cold weather, when I go to 10.5:1, cams, and stage 2 heads, I'll be way too lean. Can't dyno it for 500 miles so I don't want to blow the whole thing up while I wait.

I figure I'll just richen up the main jet now (easy fix) and see. Looks like raising the needle is more work so I'll skip that until after my build.

I don't know SQUAT about Mikunis, and even LESS about the new ignitions, but I'd check your ignition settings with someone who knows first...that's what this sounds like...and ignition advance adjustment....

It's possible my timing isn't spot on, but I still don't want to be lean no matter what so I think I'll do the jet. I'll check the static timing, too, but don't have a way to do the dynamic timing.
