Steel reinforcment ring
I am intrigued by the steel reinforcement ring that you refer to. Can you direct me to a picture that shows it and it’s part number?
I retro fitted a kick start to a 3AJ and a 1991 XT600E a few years ago, but wasn’t aware of this part. I don’t remember there being a gap between the seal that replaces the plug in the right engine case, and the case itself that this part should have located in. Can you explain how it locates? I am about to transfer the kick-start from my old 3AJ to its replacement.
I didn’t bother fitting the decompressor components on either of our bikes, and had no problem kick starting them. I would suggest that for an occasional back up it isn’t necessary, unless you are quite light.
