transmission not disengaging when letting off throttle.

[scooterted]

Transmission doesnt disengage until the engine drops below a certain rpm, it will stay engaged until then regardless of throttle use.

The certain rpm is dependent on a few things, like the 3 clutch springs, and the weight of your clutch shoes.

Cool. So that's one thing I don't have to worry about.

[pinkscoot]

Its possible your rollers are sticking.

[scootnewb]

That's something I want to change but I have no idea what weight to change it to.

Im kinda hooked on sliders vs rollers , seem to last longer & transition better. In 4t's im good aroung 5-5 1/2 gram. (6-6 1/2 in roller) but thats just my preference.for my setups.

[scootnewb]

I'll try sliders. My transmission/clutch is stock. You think 5-5 1/2 gram sliders would be good for the setup in my sig?

[scooterted]

I used 5.5 sliders while 50cc. At 72cc im currently at 6.75. But ill be dropping down a little eventually. I currently accel at 7500rpm until the variator maxes out.

Edit: this is all with a 1000rpm contra spring.

In my 49cc I have used everything from 4 grams sliders up to 6.5 gram sliders. You will have to tune to your set-up. It depends on what variator you have and what kind of clutch you are running and how the springs are right at the moment of tuning. Oh, and your belt also make a big difference as well. In my entire range of sliders I have been using, my goal was, and still is, to maintain as close to 8,000 rpm from start to top end. Now with the 6.5's I am at 7300 take-off and 8,300 top end. I still need to bring it down a little. There are too many variables to try to copy someone else's slider weights even if your set-up is close. Of course, you sort of need to do that to find a starting point but, do not be surprised how many times it takes to get it right. I am so good at pulling my cvt cover off and changing sliders that my last change, I did at work and it took 14 minutes from start to finish...that was doing it by hand...no power tools at all. I am thinking I really need to be running 6.75 gram sliders now so, we will see.

The thing I detest the most is that when you finally get it perfect, and it runs right where you want to be...then...after a month or so...it begins to drift away...either higher...or lower rpms. Or, you slap on a new belt and boom...time to tune all over again. Maybe you will get lucky and nail it after only 2 or 3 tries. Best of luck to you.

The clutch engagement is based on the driven pulley being turned by the engine. The disengagement is based on the driven pulley being turned by the engine or the rear wheel. As long as it is spinning faster then the disengagement RPM it will not disengage.

I'm using 5.5 gr sliders with a stock metro and it seems to be working very well for me, even at my 200 lbs and have actually gained a few mph before the limiter kicks in.

If you want to lube the slider or rollers mark up the weight's path with a nice fat old time #2 pencil. Or try one of those flat carpenter pencils. 

If you think your rollers are hanging up be sure to check that their paths are still very smooth. If they're gunky or anything like that clean it up with your favorite solvent but don't use solvent on the weights. You never know what solvents will do to those man made materials and it could get ugly fast.

And there's a possibility something in the clutch has gone bad?

I took off the CVT cover and things looked good. I haven't done any moe checking than that. The scoot has 500km on it almost.

I guess what I was experiencing was normal. I just never noticed it before.

The drive drop out was not was that noticeable With my TaoTao but when approaching a stop with the Metro it is a very noticeable drop out at maybe 2 or 3 mph but you really know when it cuts free.  I hope I'm not comparing apples to oranges here but I'm guessing you don't have a problem with the drop out.
