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.
Clutch pad shape
- Thread starter HT2005
- Start date
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.
stickers no, both mine and all the one's ive seen have it stamped into the caseing (exhaust side) above the mount
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!
