Apparent leanness but idles perfect!

[love2ride1111]

I just finished up pulling the exhaust , cleaning it all up and remove some gunk on the flange and exhaust port. Got the new crush O ring gasket , put it up on the port ( held it in place with 2 drops crazy glue ) and then I covered the pipe flange with the high temp gasket maker you suggested. Waited a bit and bolted it all back slowly . Tightening all bolts a little bit and rotating until everything snug.
Im hoping that FIXES  the cause of it being lean. I will post a picture of the last pic of spark plug color and what the inside of the variator now looks like .

said variator is toast and that plug is lean like 0-100 beef lean. the old girl needs some fuel bad and that exhaust could deff be contributing to that. the hook for the electrode wasnt reddened so atleast it wasnt running hot but you may need to up the main jet a few sizes even if the exhaust fixes your air leak. ive never ran a motor that lean before. if micheal jackson was still around hed be asking your secret to how you got it so white...
jokes aside i hope we can get this thing dialed in and if you need any of my old variators i will never use again and they may get you back on the road. one is a malossi multivar which is a decent one.

That was quite an hilarious comparison. I hope my secret fades away. Yes I PM ed you about the parts. I guess I could also turn the Air/Fuel screw all the way in for more richness ,I think it has a turn or so remaining in it. Do you think it is harmful if I rode it up to grocery store about 4 miles away with these issues ? I also was going to drop in different rollers( at my storage same distance ) because Im now pretty sure the wobble is the torn up rollers unbalanced because those new ones ( did not take close up pic) the metal was actually torn on the sides of a couple till I get new parts.

keep the rpms low to keep the imbalance down and youll have better luck and i would deff turn the screw in to help as much as possible. it may suck going slow but if it saves you from headaches in the future its worth it to me. i personally wouldnt ride mine if that happened but have driven under some pretty bad conditions in the past so i know how that goes. take your time and go slow and youll have a better chance of not breaking anything else. but i would keep riding to a minimum for obvious reasons. and yes sometimes i use some pretty weird references/analogies but sometimes lightening the mood a little can go a long way.

If you look at this OLD manual,you'll see that the mixture screw only works to 1/4 throttle;

Thats why I posted early in your thread about the jet needle may be the wrong type(4 stroke)and trying to adjust it richer..Putting in a richer main jet will help a lot also,but the jet needle plays a huge part 1/4-3/4 throttle..Looking at that plug says that the piston may not last much longer if run that way...

[chehystpewpur]

listen to mech on this one as he is one of the people that really helped me out in the past. hes a smart guy and his change is always good in my store.

[love2ride1111]

Its a 2 stroke and the plug was looking much darker till something changed. The jet is a 95 which came extra with the carb .I can change the needle pretty easy , but my point is I don't want to overlook the real leak.

[chehystpewpur]

i think he was saying the needle may be for a 4 stroke and not a 2 stroke but i could be wrong.

[love2ride1111]

What is the consensus of this plug color ? I redid the exhaust gasket thought I tightened it up but its still super loud , I think its helped some with my lean issue. Take a look .

[190mech]

Looks a lot better,,try raising the needle a notch(lower the clip) and see how it acts then..

[love2ride1111]

I just put in this Molossi variator yesterday ( Multivar ) and its acting all kinds weird , and sounds. For one the faceplate clips going in putting it together completely stuck snug to rails so not allowing it to Variate , it did not move and it came with 9 gram weights. I am a little concerned of super high revs but I understand it should loosen up with some miles under her belt and shift but right now its reving super high and not really shifting . SO its hitting 10k immediately and hard pressed to get over 30 . My top speed has been 68.

[chehystpewpur]

you could always do the work for it and try working it back and forth for a little bit. i cant say i would recommend adding some lube as it could saturate the belt but i have tried a few diff things on my variators in the past and residue ends up being a problem. use the drive boss to push the backing plate out and push the plate back in with your other hand and keep going back and forth until it loosens some. its frustrating having to sometimes but its the price you have to pay for tighter tolorance and long term reliability sadly.

when i got my overrange it was almost as tight but would stick all the way closed if i pushed it closed so i was lazy as i had to go to work the next morning and had to do alot of electric start removal so i hit it with a touch of sand paper and ordered some new clips as i knew it was going to wear them alot faster that way. just enough to loosen it up to not stick. and a little while later after it got some wear on the surface the clips ride on i swapped clips and all was well and still is today. these clips take forever to wear as they are much larger and stronger than factory style.

I just took a trip in to town to the Walmart , it was actually really fun being able take turns low and accelerate out so you wont fall over , lol . Yes those clips were really nice and beefy and I was like thank god these ain't gonna break....heck they aint gonna work either ,lol. But that is a good idea I could work them with some sand paper. So what you finally did was just put in new guides and then it worked. I seem to have had the problem that they seem to fall off for some reasons . I think If I switch Ill super glue them in place ! I will go over to storage in morning ,open her up and see whats going on. It ran pretty nice , just no top speed and there is a one small tink tink sound that hadme concerned , almost like one of the bolts on the exhaust is loose , and that would be awesome easy fix !

[chehystpewpur]

dont super glue them. they need to be able to move around a little when they want to. if you lock something in place thats not supposed to be bad things happen with centrifugal force. let em wiggle and wobble malossi knows what they are doing. yeah after many many miles and they wore down some. i think on my overrange now i have over 10k miles on it and 1 set of replacement clips somewhere in that time. but dont sand them much just a couple quick swiped to free it up some and let it do the rest so it can wear in the way it needs to if your going o use the sand paper. or even a square file if you have one. round would work if it fits too. always do the bare minimum when removing material on a wear item as you cant put it back in the future. when i send some pieces over to you there will be some slightly worn clips that should fit and maybe you could just save your new ones till the somewhat worn ones get loose. i replaced them too often as i thought the rattle was a bad thing since that was all new to me but it was a waste of time and money its normal with those things. as the motor speeds up and slows down it makes some noise seeing as how it is much stronger and has more mass than the stock parts.

if youve ever done a valve adjustment on a motor before its kind of like that. old school lifters and cams made noise gear drive timing components make noise dual mass flywheels and clutches sound like crap but it works. the stronger something is the louder it usually is in many cases unless it was designed to be quiet and powerful and its gonna cost alot more than 100 bux. some of the aftermarket variators have splines on the backing plate and it helps keep the noise down some but those ones also have their drawbacks so it is what it is.
