I know there was a few guys talking about doing a CR 480 swap into a '81- '82. Did anyone ever do one?

Well I thought I would ask before I showed my project that I was working on.
I bought an '82 250R 6 months ago, from a guy in Las Vegas for $225, with the intent on turning it into a 480R. It's been sitting up on the top shelf of " The Rack" for a while now waiting for a '83 480 to come along.

Well I bought a 480 on e-bay a month ago. It showed up last week. As soon as it did I got the '82 R down and yanked the motor. Set in the 480 and went to work engineering the motor mounts. The motor fits in perfectly. The 480 is a little taller but the cases have a smaller foot print than the 250 motor and has more room in the frame than the 250 does because it doesn't have a counter-balancer.
My assistant: This is my "just turned" 6 year old. He thinks we're working on this for him. He makes time go by fast and asks a million questions.

Took a couple days to get the mounts exactly the way I wanted them. I made 8 different sets of rears and 12 different sets of fronts before everything fell together. The nice thing is having a CNC plasma cutter. I couldn't imagine making these by hand!
The spark plug will come out with a plug scocket. The oil drain plug is set perfect to get to and the motor sits .150" above the frame rail.

I machined the aluminum spacers for all three mounts. I used a Sprocket Laser to align the sprockets so the dimensions for the spacers would come out perfect. The front motor mount bolt won’t pass through because of the frame rails so I had to make a double-ended bolt for the front mount ( threaded on both ends / smooth in the middle).
I've got another set of shelves coming that same size. I have a few more machines to put up. Right now their on the roof of the office and on benches around the shop.
Anyway here's more on the build....

Once the mounts were right it only takes 20 minutes to put the 480 in and bolt everything together.
Now its time to tear it down. The frame and other stuff to powder coating. The motor gets torn down and rebuilt. I pipe is also in the works. In a week or so I'll post more phot's on the progress.
If anyone is intrested in doing a 480 conversion on a '81 or '82 250R let me know. I'm putting together a conversion kit with all of the hardware (motor mounts, bolts and spacers). The kit will be $180 and should save someone a lot of time and fustration.

Nothing take negitive. I like junk and turning it into something. My Cagiva was a basket case and according to my wife " I shouldn't have wasted the money on that pice of crap". Glad I didn't listen to her.
I'll have $2,300 into to this ride when it's done, including the West Coast swinger, paint, plastic, rims & tires, shocks etc. Thats less than a '85 R is in less than OK shape. Alot faster too. When it's done it'll be another "bad ass trike". Let me know what you think when its done.
Best of all I love doing it.
