When you're wot and you run into the bog,,,back off the throttle a bit ,,,if it picks back up and gets strong again this indicates a lean condition

I try to look for this but I only feels this way, but won't go faster.

OK, got the 13 gram sliders installed. Cleaned CVT.

CANNOT wait to test it out.

Good luck!

So I got it up to 50 MPH. Not sure if this was a good test as it's cold and windy.

I'll retest to make sure. No bogging though. Yeah

When I opened the CVT cover it was dirty, cleaned. But I noted that the driven and drive pulleys definitely are not using all of the range for the belt. Both only went to just shy of the top by 1/4 inch or so. Might have to get a different belt.

The contra spring must be messed up. It's the correct belt.

I have still got a problem. I like the way the 13 gram sliders are feeling. However, I cannot get past 45mph. If my contra spring is bad this would cause this correct?

I say this as I've read the library about the rollers, variators and clutch/driven pulley. That's something I got from this. Also noticed the drive pulley (variator) isn't showing belt markings on the last upper/outer part of it. About a 1/4 inch.

Could be the contra spring ,,,but what is the width of the belt would be my first look

I always used a longer belt on my 150 and had a prodigy variator. The belt rose to top on both pulleys and had quite a bit lighter weights.

21 mm, my OEM is 799x19x28

I replaced it with a new one. The old was width 18.5 mm. Don't have any idea if that makes a difference. Doesn't appear to.

I have different sliders. 14 gram rollers, 13 gram sliders, 11 gram sliders.

Did different types of combinations. None would get past 46 to 47 mph. None would get the belt to ride all the way up.

The scooter seems to love getting to 45 mph and seems like it could just go right on past, but since the belt won't travel to the entire front pulley outer edge I won't get past 45mph.

I personally like the combination of 14 gram rollers and 11 gram sliders, also the 13 gram sliders, and I like a mixture of the 13 and 11 gram sliders. Just the 11 gram sliders is to much RPM's too early, and doesn't sustain past 40. Actually wouldn't go past 40mph.

I don't know which would give best gas mileage. I don't know which will before better at top speed as I cannot get there.

I have ordered a koso 115mm variator and the fan. I also have a clutch spring 1.5 k coming.

What do you all think?

[tvnacman]

what size wheels and what size belt?

What is your peak RPM at the speeds you are indicating?

Belt is 799x19x28

Wheels 12 inch in getting, 10 inch in back. Cannot fit anything else. But that didn't matter before. The scooter did hit 55 mph with stock everything and I was heavier.

Shop did stuff and it won't go over 45

I have an RPM Tach but it's not very good. I don't trust it. I also did this when the sun was coming down and it was blinding so I couldn't watcha tachometer
