Mike's '82 250R build

[M.Pargiello]

Alright, I have gone through the parts. Engine will be no good like I figured, also need a gas tank and wiring harness. I haven't dug around much yet on engine prices, but what are some available swaps or good engine sources? I think I am definitely wanting more than 250cc's for this build. Haven't found any good first gen swap threads yet to know what I can do. Or would it be better to just do a big bore on a 250? Thanks for the suggestions and comments so far

cr480 will swap in. look up threads by bigbore

I did end up finding that one last night. Looks like a seriously easy option! The hunt begins... Who wants a first gen 250R bottom end and an '86 fat cat engine? Both need work, I need 480

i think thats the best one I have seen on the 480 conversion. Your best bet is going to be finding a cr480R bike around and buying it whole; you will save money and be able to yank the electronics, carb, motor, and small related parts needed. I keep pushing my sisters bf to swap his 83/84 R to a 480, looks like an awesome conversion! I am in for updates, esp if this pans out as a 480!!! Good luck man, and congrats on the family!

Hey Mike...I don't know if you checked out that thread that Jason just posted but holy crap! I would contact that guy in france to see if he can get you another set of those mounts made! All you need to do then is find the powerplant and stayed tuned to how that guy realigns the kicker and you are good to go my man. Thanks for sharing Jason! I don't know how I missed that conversion thread.

Edit....check that comment on the engine mounts.....he used a second gen frame I don't know how different the mounts are, but I would imagine there is quite a bit of difference.

[M.Pargiello]

Mounts will be easy to make at the shop. I don't have big machines, but I have learned some tricks over the years not sure if I want to extend the kicker out or just remove rear plastics to start it.. If that is even possible.. But I think it will since the swinger will be longer as well. Don't really think I want to crack the throttle open on a 480 with a stock first gen swinger haha

[M.Pargiello]

Well I jumped on it sooner than expected, got the frame and forks back. It was spray painted some nasty brownish red. All fixed now. Still gotta fix the nut on the stem, looks ned also



My wife is not thrilled about it in the living room Now for little things, I am getting all new hardware for it (not the eBay kits, piecing it together myself), polishing some bits, and finishing the swinger, axle, and rear shock. Unless I get a good deal on an extended swing arm, then stock it will be.

And now that I look at it, I see I put the forks on the wrong sides and backwards

The mounts should be in the same location between 1st and 2nd gens. My 82 has an 84 power plant and nothing looks "hacked together.

The 81-84 engines are the same with the shifter shaft on the 83-84 being shorter.The 81-82 engine mounts and cradle is totally different than on the 83-84.Its alot harder to put a 480 in a 83-84 frame than 81-82.Bigbore has the 82 frame with the 480 in it. He used to sell the kit he designed and modified pipes.

i happen to have a narrow wheel tire hub combo specifically made to put a narrow front tire on the 81/82 250r using the OEM triple clamps and forks. i dont plan on letting it go.

Is it an aluminum adapter plate from the 4-130 OEM hub to the larger 83-84 rim size? My 300R Ice Racer came with one. Pretty simple plate if someone wanted to CNC...
