It would be similar to a CRF conversion, however with the ease of a forward kickstart, and the pivot bolt would fit easier.

do you have any fabrication skills? you have to make collors to fit the swingarm bolt that also align the chain as well as getting the right motor angle. theres alot involved i worked on my yz conversion for about 2 hours every day for three weeks.
