I'm getting too old to keep kick-starting my pan so I decided to fabricate an electric starter mount. There's a couple on the market ranging from $1800-$3000. They use special starter motors and drives. I designed a mount that uses a Sportster 1981-2014 starter and drive that cost about $110-$370. If your clutch basket doesn't have a ring gear you purchase one for $30-$60. The tin inner and outer primary need to be notched in the back. I haven't gotten to notching the primary yet, still testing the prototype mount to insure it will work properly. I will post pictures and update them as it progresses. I'm thinking about marketing this item if all goes well. The complete kit is estimated to sell for $800.00. Save a thousand dollars and replacement  starter is a stock Sportster starter

Waiting to see the final product,  Using the stock Sportster starter is handy for replacement.

Tested the starter and it cranks the engine as it should. Now that I know it's going to perform I decided to cut out the tin primary cover. All the other aftermarket products require this modification to the tin primary cover.

That looks great. Not sure it would work on my xlch. There appears to be quite a bit more room between the rear wheel and motor than on the sportster.
Also I would have to change the oil tank and make a mount for a battery. Since I only ride it a couple time a year I think something like the Doc Z bump starter would be my best option, I would just like to know how well they work.
My plan for now is to have my Grandson come over with a friend and bump start it.

I have a friend who owns a Z start and he likes it but it's designed for the track, it's big and heavy with the battery

I believe Doc Z makes a couple different models,  a smaller version for use at home, that's the model I am interested in.

The unit is small and light, it's the battery that makes it not easily portable. I have a friend in Vegas who owns a motorcycle shop specializing in older bikes and this is what his shop uses.
