sticky starter?

Took the R-75 ISDT replica for a ride yesterday, ran great, while coming up the driveway, the starter seemed to want to engage a couple of times. bike is a 75 R-75 /6. all new harness but old relay any ideas? Thanks

I would have pointed at the harness, that being new, I doubt it has rubbed through anywhere. I would toss in a new relay, they are pretty cheap, can improve your starter performance a surprising amount, I recently found.
Not really sure how that would cause the starter to randomly engage, but sure cant hurt.

Randomly engaging when the engine is running will damage the ring gear on the flywheel. That is not a good thing

Had you just washed the bike?
Water in the switch gear can cause the starter to engage, ime.

This happened to me the other day. Also while in the driveway, as I was maneuvering my bike back in the garage. I was stumped for about a minute, till I noticed that as I turned hard right the starter button was grazing the tank and engaging it

I am replacing the relay, this bike was a wreck that spent some time in the weather without a tank or tarp. The valve covers were off it and the springs were so pitted that I tossed them and replaced all the needle bearings and pushrods. I'll check the starter button also. Since this was the first ride on it I'm not too concerned and will deal with the teething problems.
