Default The Frankenbike project

     

Some have seen my previous bike projects and I would say they turned out pretty sweet. The other day I saw an article about Chad Reed starting up his own team and was going to piece parts from different brand bikes together. This kinda sparked my interest................not that I need another project, but I had a bike pretty much fall into my lap and it got me thinking. I have always wanted to take my wife's XR200 engine and put it in a MX chassis. Well she won't let me touch her bike other than change the oil and ride it. A buddy offered me his 85 XR200 (the one with four valves and dual carbs) He had an issue where he lost a rocker arm and it did some damage to the head cover. Well I was thinking the thing was toast. He showed me the cover the other day and it wasn't anything like what I was expecting. So I hoped on ebay and started surfing. Was wanting to go with a CR/CRF frame, but then got to thinking steel would be much easier for me to work with. Today an 01 YZ125 frame, swing arm and plastic showed up. I picked up hubs for a YZ with plans to build some wheels and am looking for suspension. Then I got to thinking since I got a honda engine and yamaha frame, how could I manage to get parts from suzuki, KTM and Kawasaki on there to really make it Frankenstein bike. I should be picking up the 200 here with in the next couple of weeks and will hopefully get some time to modify the frame for the new power plant. Planning on making this project as long as my XR450 project, but it should be just as sweet when it is finished..........also thinking about getting a second set of suspension and having it internally lowered so my wife can ride it as well............since she is a little vertically challenged

You have too much free time my friend! And if you don't get some pics up soon, I'm afraid I'll have to ban you...

Thumper, that 4 valve/dual carb 200 was an 84 model. I bought one new, but it didn't hang around very long. Be carefull hopping it up. My valves wouldn't stay adjusted and those carbs are a pia. Couldn't keep the chain on (won't be an issue in the YZ chassis- I traded it before I learned of an updated chain guide). The 2 valve motors might be better for a project. But I am looking forward to seeing how you Thumper-ize it!

I was hoping to use my wifes 99 XR200 engine, but she wont let me touch it. would have preferred to use the two valve set up since it is a little narrower on top, but you cant argue with free. Plus the 4 valve can produce more power. As for thecarb, I am going to outfit it with a single. I would like to stroke it and bore it and find a beefed up cam for it. Maybe even lighten the fly wheel a little. If it all goes according to plan it is going to be one bad @$$ little woods bike. Just gotta figure out how to add an oil cooler to keep the thing cool since I heat this model has a heat issue.
