Clutch pad shape

HT2005 · #1 07-05-2009, 06:03 PM

Some people here have been posting about circle-shaped clutch pads that are on newer engines. I have seen these posts on threads over a year old. However, recently in early June, I ordered and received an engine from Gasbike.net (66cc) that had the polygon shaped old-style pads. According to the EPA sticker from the engine, it was produced in February 2009. So, apparently the "good" pads are still in production. I bought the Jet 80cc by-the-way.

I have an old 48cc (Gen 1 A1037) with round pads.
and a 2009 slant head 48cc (Gen 3 C437) with Trapezoid pads?

What numbers are stamped on it?

If you are referring to the numbers on the sticker, then I can't tell you. The sticker was peeling off so I removed it and put it with the garbage. What I have concluded was that not all of the newer engines have cheapened clutch pads with small surface area.

That's odd. My 48cc bought in August 2005 has trapezoid-shaped pads. They are the same shape, size, and color as the ones on my new 66cc.

here's a good question, where do i get new pads? and do any of you have any pictures of an teardown and rebuild?

I believe this site has the old-style pads: Bicycle Engines, Motorized Bicycles, Bicycle Motors, Motored Bikes: 2-Stroke & 4-Stroke Kits!

There are other threads around this site that show teardowns that others could link to.
