86 250r build up

[aviomech]

I just bought an 86 250r frame this last weekend(excellent shape-$50) and want to slowly start building it up. I'm looking for suggestions on what type of motor I can or should put in. The cr500 looks cool(and difficult), but are there any 4-stroke motors that will fit?? Any other motor that can be put in with little hassle?? Thx Tim

hmm,, idk maybe a 350x,, i saw an 86 i think with the new 450r engine from the crf450

those 450 motors are TALL! It would be much easier to put in a CR500 and have a pipe fabbed up.

Possibly the new four-poke 250cc engines but idk. I just know all those motors are tall.

a 250R engine fits nice and makes lots of power.

a 250R engine fits nice and makes lots of power. this is the very best option...unless your looking to make something different.

Thanks for the input guys.

I was just getting ideas just in case I ran across a good deal on a motor that would fit. I sorta figured the 4-strokes are a little tall for the frame. I am leaning toward a 250r just because I could just bolt it in, and bore it out later. Just having some friends trying to talk me in to the cr500, seens how I already have an 82 250r. I just don't want to get into any major frame alterations.

Anyway, I am still in the beginning phase of getting some parts together and preping the frame. The frame looks great and I hate to mess with it, but I think I would like to paint it blue. I'm thinking a blue, silver, black trio of colors for the whole trike. Just haven't figured out the what and wheres. I will post more as I get futher into the project.
