**vartiak15** · 01-31-2005, 11:38 PM

well i got a piston kit for an 84r and its the 200r psiton. is there anywhere to get a sleave so i can make the motor a 200r? im planning on getting an 84 r in about 4 monts or so. (save up some cash) and im going to make it the "old school racer" style. let me no can i make this piston work in a 84 250r?

here is the link http://cgi.ebay.com/ebaymotors/ws/eB...e=STRK:MEWN:IT

Thats sweet but what about when you wear out the rings or accidentally melt the piston or rings?

**vartiak15** · 01-31-2005, 11:48 PM

well than im screwed and bore it out for a big piston lol.

OR, you could take that 200r piston to a machine shop and get multiples made!

**vartiak15** · 02-01-2005, 12:03 AM

yes i could do that. where would i get rings made tho. same place?

Even if he spent the crap load of money to get the pistons reproduced what would he use for rings Pistonhead?

Why not see if 4-stroke 200cc rings would fit it? What difference would there be between piston ring sizes?

**Pistonhead** · 02-01-2005, 12:18 AM

I wonder if a set of rings for a blaster would fit?

I must be missing something? Why would you want to sleeve it down to a 200cc? That was originally done to make it legal in a 200cc class. Since 200cc trike classes no longer exist, I dont understand the purpose. Its going to be a lot less expensive buying the right piston kit for your cylinder, as opposed to making your cylinder fit the piston you have.

i would have to agree with timsr...... completely pointless, unless you were making a vintage racer for a museum.....but it would be cool to say you have a 200cc 250r that has parts you cant get anymore in it....idk my opinion....

If your that hardcore about doing this, there might be a possible way to get the air cooled R cylinder fitted with a blaster sleeve and piston, but would probably be cheaper to just put the blaster motor in the frame.

He has everything he needs to make it a 200cc oldschool racer except for the sleeve. Finding the sleeve may prove to undo your project. Contact Wesico and L.A. Sleeve and start asking questions about any old sleeves or about how they can help you.

did they even down sleeve the air cooled R's? i thought they only did that with the water-cooled ones?

I always thought that they destroked the crank to make a 250r a 200r. Or did they resleeve and re-bore it? Or both?

Biggreenmachine you said he has everything but the sleeve. You forgot he doesn't have a bike either.
