Re: pic: Kit Transmission Upgrade kit
 

Thanks for the advice.

It's true that we listed a plastic spacer on our instructions, while sending washers as a replacement. We have changed our documentation being sent with these upgrade kits to reflect this change, as we have received 1 email about this issue also. I apologize that our documentation had this error.

The one thing I would like to have better with this kit is the tightness of the "D" holed, 28-tooth gear. These gears are being broached to be a very snug fit on the D shaft of the Mini-Bike motor. If the motor's shaft is marred slightly (by beating on the shaft to get the manufacturers' gear off... or by the manufacturer's gear set screw), then our 28-tooth gear needs to be pressed on firmly.

I suggest 2 things to help this situation:

1. Use a scotch-brite pad or a very light sandpaper piece to clean up the Mini-Bike motor shaft before adding on the 28-tooth gear.

2. Heat up the gear to expand its hole before putting it onto the motor shaft.

These two steps should help facilitate this installation. I will add these to our documentation also.

ahh..this might be random. but nonetheless important.

for the large cim motor, aka: bike motor, are we allowed to take out the gears and the springs that are already attached? b/c we are planning on using the output shaft directly connected to a coupling...and so on...

so again...are we allowed to take out the springs and the black gear thing..??
if so..HOW CAN I? i tried to pull it out..it's pretty much impossible.

Yes, you can remove them. If you look at the rule about modifying the motors, it allows you to modify the output shaft/mounting points.

Do a search for the thread about removing the pulley. The short answer is you need some sort of gear pulling device, and a heat gun/blowtorch with which to heat up the gear (due to the adhesive used on the shaft).
