It's a 125cc

what is the engine number?

XS1P52QMI-3

[tvnacman]

152qmi or as stamped 1p52qmi. I would install a 835-20-30 belt.

I couldn't figure out the belts from the library. I looked in CVT.

I can not back it up with documented specs sheets, however most parts are listed as 125/150cc. The main difference is the I and J in the engine number. The I being 54mm=125cc and the J being 57.4mm=149cc.

If you answered simple questions it would help. Like how many bolts hold the cvt cover on 8?

Lol, 8 but I think I lost one so maybe 9.

I'll make sure once I get home. I think I have received the spring

[seanstr]

OK, received the new 1.5k spring. It's installed.

Wasn't even sure it would fit.

It did yeah.

Thoughts before install. Had old one in hand. Super weak. New one more firm. I realize the stock is probably .75 k or 750 m but just seemed weak.

Installed and it was very hard to compress the driven face to get belt on. Normally very easy.

When my wife gets home I'll go test drive. If it does what I think and I get to 55mph or more in done. I think my peak RPM's is about 50% throttle. Then it gets to 45 mph and just stopped before.

If it was a weak contra spring then it will just keep going. If not then the OEM spring wasn't the problem.

Oh and it's definitely 9 bolts for CVT cover.

[seanstr]

OK new spring seems to be helpful but only a little bit.

I still need a longer belt, not a shorter belt.

Comes with a 799 x 19 x 28

What is longer.

Here's the image of a different belt that is longer but it's too wide and too deep.

842, thats what I used on my 150

But it's a 125cc and the engine number doesn't that matter.

Is there a way to just measure the area?

I measured. I think it is 842. Is it a longcase 125cc?

[seanstr]

OK got a Kevlar belt coming from Amazon. 842 x 20 x 30, should be here Friday. Koso variator on the way. Already received the fan from koso.

[tvnacman]

I was going to suggest the 835 being you don't have 10 cvt cover bolts.You say you have 9 was one missing (the tenth) or did you maybe count an extra bolt some how.
