Yes they are in the parts diagram but they are not available through OldMiniBikes. They are 35mm x 15mm x 11mm per my mic. Through a lot of searching with the dimensions I came up with a 6202 2RSJEM bearing number. They are available on Flebay and are priced all over the place. From $9.95 with free shipping to $3.99 with $16.57 shipping to $24.99 with free shipping. Just had to dig but this is what appears to be correct. I have some on the way as of today and will post if they fit or not. Thanks
Stop and read the numbers on the the bearing.
I forget what they are but I bought a set of double lip sealed bearing for as I recall 1.99. (were they a 6002 ? )
These are a standard bearing used on all kinds of other things.
The jack shaft bearing I used were also a standard part I think a 6204 or something and the ones I used were also a double lip with a temperature grease inside ( intended to cold application like snow machines )
The engine uses a 6205 c3.
Any one will do but I prefer a FAG or SKF.
I do not care if it has seals or not, what ever is in stock and I just pop off the seals or shields ( also a 2.99 part )
