I bought someone else's unfinished project from Ohio. It's an 84 ATC 250R with an 82 CR480 engine. This was the original build thread from who I can only assume was the person I bought the project from. http://www.3wheelerworld.com/showthr...highlight=480r
For those not familiar with the CR480 engine, it is a four speed in 81 and 82 trim, with the 83 engine being a five speed. They are all left side kick start with the counter shaft on the right side. The right side counter shaft makes the first and second gen 250R's a good choice as a home for this engine as they are right side drive as well. This engine is 55hp from the factory which is good, I can have fun with that, however it is not going to be enough. I bought this trike over the winter with the greatly appreciated help of Kiser, who was my boots on the ground. He drove quite a ways to go look at this bike for me and yay or neigh it. If it weren't for him this may not be happening right now. Also big thanks to Specht for storing it. My sister and her husband were able to pick it up from Kiser and Specht on their way up from Arkansas, so I just had to drive 45 minutes away to pick it up. The original plan was to have it ready for Trikefest. I was going to build it all myself. Then I got wrapped up in my Mustang which consumed gobs of my spare time until work picked up for the season and there was no hope for this bike this year. I jokingly asked Dan if he felt like building it and much to my surprise he said sure! I was only kidding when I asked! So I picked it up a few weeks ago and dropped it off to Dan. When we went through everything it was a bit disheartening at first. It literally needed everything aside from the engine. The engine appears to have been completely rebuilt and every gasket is brand new as well as the top end. It doesn't even look like it's been fired. The bike needed literally everything else. Very little progress had been made, next to nothing really, as far as engine fitment and mounting. The 480 pipe is useless, the ATC pipe is useless, and all braking and control systems need to be made pretty much beginning to end. Ironically enough the drag pipe from the Tecate 500 fits this 480R like a glove! I was tempted to use that pipe on this project, however having read up on the 480 I found that they do not respond well to pipe alterations and everything I read says nothing is better than the factory pipe on that engine. So we have a trick coming possibly. I don't want to say much yet because time is of the essence and sometimes things happen, sometimes they don't. If this happens 55hp will be a number we can all get out of our heads and then some.
The build is happening at Dan's house and once again he's taken the bull by the horns. He's able to go out there after work on weeknights on his own and has made a lot of progress on this by himself. I spent the day there today and we killed it. We got a lot done today. Up to this point it's been mostly motor mount work and building the main rear mount that both mounts the back of the engine and the top of the rear shock. It's the one the swing arm bolt goes through. Basically a lot of cutting, grinding, and welding thus far. The kick starter needs to be extended out in order to clear the frame. In order to accomplish this we will be welding two kicker bases together. I got the idea from some kid on Facebook.
