I can answer most questions regaurding rebuilding/restoring and troubleshooting vintage two-stroke bikes from the late sixty`s up until the mid eighty`s. Current two-stroke machines and tecnology is not my forte` but I will answer those questions to the best of my ability. I am most familiar with Yamaha`s RD series as well as Kawasaki models from the same era.
I have restored many bikes and worked on countless others. I have grown to be a good troubleshooter over the years and there haven't been too many problems I haven't seen, experienced or heard of reguarding two-strokes. Though not my profession, I have become very skilled in this area.
