Hi, I'm Paul and I've just purchased a non running mvx250. Chasing a wiring diagram to help sort out some bugs. I've restored many bikes over the years especially honda cbr250rr (mc22) and I still have many parts lurking. Just finished a cool looking rebel 250 made to look like a 1940's army bike. I'll try and post some pics.
Neither have I until that garage door went up. He wanted a carton for it. I couldn't give less than $100 for it. Even if it doesn't ever run or get on the road. Very interesting bike to have in my collection.
Paul.One of my mates bought a new MVX 250 back in the days , went pretty well but it did have a strange note though.
Welcome @DMC Those MVX250's are a rare bird. I've only ever seen 2 in my life... one for sale and one at Broadford a few years back (see pics). They share many parts with the 1983 VT250F. It was like Honda decided to hedge their bets and release a 2-stroke and a 4-stroke in basically the same frame and with common running gear. I'll be following your build with great interest. best of luck.
You can always get this model from Tamiya http://www.tamiya.com/english/products/14023/index.htm Although, I think there was 2 versions of the MVX250. The Tamiya model is the one with more plastics. Their spiel suggests 40hp, but I was under the impression it was closer to 49hp and the engine was more torquey than your normal 2-stroke.
I hear you. "Time Poor" is a pretty common sentiment on this forum. It's unusual for a mass model maker like Tamiya to produce a model for a bike that had just one run. The MVX250F must have been very popular in Japan. They certainly made plenty of VT250F models (see below). I have some experience with the VT250F, so might be able to help you on non-engine related issues. Good to see Grey has provided a wiring diagram for you. Good luck.
Thanks grey for wiring diagram. This will help heaps. Yeah frankster I've been told heaps of parts are the same. Trying to engine to start first and go from there.
There were quite a few sold here in NZ. There's a thread on Kiwibiker about them with some good info. In my limited experience with them, the ignition for the center cylinder seems to die as a common thing. Piston problems in that pot too are common as to solve balance problems, in some versions I believe they have a much larger OD gudgeon pin in that pot... They're an oddity - but a running one is actually quite nice. Good find.
