Vintage MX Consumer Alert - Buyers Beware

Be careful before purchasing any bikes from Mark Harris of Bullhead City, AZ. I recently bought a 1979 Honda CR250 that was supposed to be 'Fully Restored'. Not quite.
When I took delivery, I have to admit, the bike LOOKED beautiful. Mark told me he had taken taken it on a test ride prior to delivery, and then admitted that it had the wrong throttle cable that would have to be either fixed or replaced.
At first, I thought the throttle issue was going to be only a minor inconvenience. That turned into a $40 new (Custom made) cable. After installing the cable, I brought the bike to a local MX Vet track in order to break it in. I didn't make it a full lap. The cable was only part of the problem, the throttle assembly was shot as well. There was not a stop, it simply went from full throttle in one direction to full throttle rotating the other direction. (I literally had to ride with one hand on the clutch and one on the kill switch in order to make it back to the truck!)
At this point, I decided to cut my losses for the day and bring it to my personal mechanic who builds my race bikes. I asked him to replace the throttle cable and assembly, as well as the handle bars (which were bent, incidentally)
When I went back to the shop to pick up the bike and kicked it over, we realized it wasn't idling anywhere close to normal. My mechanic then pulled the carb and discovered a considerable amount of DIRT IN THE FLOAT BOWL. After some furthur adjustment to the carb,we re-fired the bike. My mechanic then said that the main bearing in the lower end sounded strange. He pulled the timing cover off and saw that the MAIN BEARING IN THE LOWER END WAS COMPLETELY WORN OUT. (Had I managed to ride the bike for any time at all, there is no doubt we would have lost the entire lower end!) Luckily, this was discovered while in the shop, rather than on the track. (His 'test ride' should have revealed this.) I now have to pay my mechanic to fix the problems that, frankly shouldn't exist.
So at this point, I have a bike that Mr. Harris claimed was ready to ride, that's spent more time in my mechanic's garage than in mine.
Again, the bike looks great, but I bought it to ride, not to look at.
Incidentally, I e-mailed Mark, with these same details, expressing my displeasure with the bike he sold me, and requested a partial refund. He never returned my message. (This from someone who claims to stand behind his work.)
I would think twice before purchasing a bike from this guy. (Or make sure you CLOSELY inspect any bike prior to purchasing.

BUYER BEWARE!
