Okay I’ll change The jets back to stock. and see if that helps... I’m running (uni filters pk-92) good filters and don’t interfere with the carb ports for about half the price of k&9s . It also has Vance and Hines aftermarket pipes..im pretty sure our elevation is only about 900ft. So I don’t know if that will affect it much.

Also you said earlier in a post that, you thought you heard variable valve timing? I’m not familiar with that term. what would Be the cause for that and how I would I fix it ?

I've got Uni PK92s and stock jets on mine. Runs great.

Loose, clacking, cam chain tensioners on your engine. At idle it sounds like your cam timing is changing on it's own.

In other words, sounds like you need a pair of MCCTs to replace the stock ACCTs.

Sorry I wasn't clear.

Edit: Elevation won't have much bearing at all until you get above 5000ft.

I changed the jets back to stock and it runs much better thank you! I also decided to try modding the acct into Mccts, like some others on here have done to save some money. Seems to be good so far. As for the hot wire harness....I started it up to adjust the Mcct and noticed a small amount of smoke... at first I thought I had just dropped gas onto the exhaust from pulling the carbs so many times, but then realized that the R/R and all the wires coming from it are so hot that they are beginning to melt the electrical tap wrapping the harness.... Not sure what that’s all about any suggestion on what I should check or should I just get a new R/R ?

You're welcome.

Can ohm test the r/r, the chart in the manual isn't the easiest to use, but it helps once you get how to use it.

Does sound like the r/r could be shorting out. Will take the stator with it if ridden enough in that condition.

Melting wires are firmly in the "very bad" category.
Is it the yellow wires or the white/brown/black wires that are melting?

May as well test the stator while the ohm meter is out for the R/R testing.

Tested the stator it doesn’t seem to be shorting... the wires all warm up but the yellow ones, I can continue to hold in my hand with the bike running.... the white and brown wires however, they are getting hot enough I can’t hold them without getting buafter the bike has run for 30 seconds or so... the white wire still looks good just very hot. The brown wire has definitely been doing some melting tho. i don’t believe the R/R is stock so I’m not sure how to test it. The only markings on the R/R are (MZS E-040)

I would try to use the stock testing chart and see if it shows any problem.

It still has the stock R/R plug, correct?

Did you disconnect the stator for testing?

Yea I unplugged the stator and tested from each wire and grounded the other lead on the engine.. no connection...... as for the R/R it has a six prong female block plug....the p/o relocated the RR and I think he replaced it for an eBay RR. The type That come with its own plug. and he just connected the new plug with crimp connections.... I also just discovered that my battery isn't charging.....big surprise 🙄 lol.
