Hello,

My son has a 2004 4 stroke mongoose 90. I am looing to do some clutch work but I have found nothing for his bike. I found some rollers from EPI but that is it. In changing the rollers, the lower the weight , the more stall you have? I was also looking to get an idea of the weight of the stock weights to have a base line in ordering some new ones.

He doesn't race MX or flat track. He just rides and races the youth mud bogs at various events I race. He needs to go from point A to point B in a straight line as efficiently as possible. When he leaves the line now, the clutch just slowly engages. I am looking for a higher stall that will grab harder and will grip the belt tighter. I run a Kawie and understand those clutches but I have no clue when it comes to his. Are there any kits out there with rollers and springs or am I just limited to the rollers?

Thank you in advance for all insight and input!

I just picked up a '04 mongoose last night. It came with a extra set of weights. maybe I can get some info off of the parts bag later tonight. I'll see what I can do.

Don't qoute me on this, but I'm willing to bet the rollers are 16x13 which is standard to any GY6 50cc based engine. You can buy them all day off ebay.

Ok, not sure if the original weights are the same, but the replacement weights that I have say 7gr. They are Kymco weights, and if you need it, I can post the part number that is on the bag.
on edit- mine is a 90cc if that makes a difference

6.5 grams for the 50cc. 39 grams total. At least for the 2007-2009 Kawasaki KFX50 thats made by Kymco.

How about you send me a pic or post a pic of a roller against a tape measure, that will give me an idea what you got.
