yeah all two stroke are suppose to have a radiator but its a cool bike

LOTS of 2 stroke engines don't have a radiator and are "fan cooled", Obviously string trimmers and chainsaws don't have a radiator, but high performance 2 cycles used to commonly lack a water cooling system. I've grown up around snowmobiles, two of which were fan cooled. We had a Skidoo mxz 440, zx chassis, went like a bat out of hell, it was fan cooled but it overheated when it was above 35ish degrees and ran on 1 cylinder. I bomb around on a Yamaha Bravo 250 these days because its light and fuel efficient. At 18 hp I wouldn't call it high performance, but come on its only 250cc, from 1983 and was kind of meant to be a "work truck" not a speed demon. Its not too fast (around 50 mph on ice), rides like a dump truck with leafs and shocks upfront, bogey wheels with maybe 2 inches of travel out back. But damn it's fun, and for only having 18 ponies and a track that is worn down to like .5 inch lugs it pulls like a freight train. The little guy almost never gets stuck. They were made from 1982 to 2012, because of their drop dead reliability, give me some gas, oil and some Vicodin (for the back pain) and I'd ride the thing to Washington state and back; it wouldn't give me a lick of trouble. Its gonna be a sad day when the track ***** the bed because nobody makes a 94" track anymore. TIME TO LONG TRACK IT. Lol.

oh yeh but i meant alot of 2 stroke dirt bikes and yeh we got a snomoble its fast 75 mph on the high way on a 55 got pulled but yeh hate to know they dont make a track for it how about you make a thread for it here in the off topic

Id rather have a long track anyway, I can get a 121 skid on eBay out of a Polaris or something for about $150, or I could do a factory long track swap. The sled was available with a 136 track. Fastest I've ever been on a sled was 97 mph, it was kinda crazy. I could have pushed it to 100 but the straight away was ending soon so I had to nail the brakes. I might make a thread on it some day, idk though.

what do you guys think i should do boar it to a 90 or a 85cc

so yesterday i got some things done on it i finished painting and clear coating the rims and all i need to finish the rims is spoke skins red and white ones and i also painted half of the frame silver because all the new dirt bikes have silver or chrome frames and in 1987-1999 honda made there 80cc dirt bikes with white frames witch look to old for me so half of the frame is painted i need to finish the rest and while i was board i made my own graphics just to see what graphics would look like on it lol pics comeing asap

Here is the pics but I finished the rims and  in this pic I took the back off the bike to paint it silver

Here it is painted silver

The silver is so light you can barley tell it's painted but all the frame is going to be silver
And this is what my bike is going to look like when done but mine is going to have a black motor

Here's a little update I took the piston off the bike a week or to ago to just get things ready for when I get a new one but it's all groves up and scard but I should be ordering parts for the motor soon can't wait to buy them I'm ordering all this

Weisco top end rebuild kit
Pro taper handle bar pad
Pro taper grips
New front and rear brake pads
Unbrakable brake levers
A new shift lever
Spoke skins
A full 2003 cr85 plastic kit
A 2003 cr85 gas tank
A 2003 cr85 seat
A full custom graphics kit from decal works
New clutch cable

And many other parts I'm forgetting but it's should all total out to be
450$ but I can get the money easily because I'm selling my 1987 suzuki lt230e quadrunner it's a nice quad so more update comeing when I get some

well guys im stil on this build, im in nc and I sent the cylinder to pa to get board and ported and I bought the piston and rings, bought new grips and a handle bar pad that goes in the middle, I also got the frame painted, cleaned out and bleded the brakes, re greased the bearings and axles, so over all ive got a lot done and its looking pretty good but I still got a lot more to do

About how much is it to get something like this engine rebored? Just curious, I don't know anywhere local that would do small stuff. I could look it up I guess. Who are you using?

well it all depends on the brand bike, how old it is, because my 1993 cr80 cant be board it has to be drilled out and re sleeved but like a 2008 cr250 can be board so it kinda depends on the bike and with this bike I can boar it to a 110cc but im only going to a 85cc and there charging 250$ for building the cylinder race ready and giving me piston,rings,bearings for those, gaskets everything I need

WELL HERES A BIG UPDATE I guess I need to find some old pics but heres it is since the old pics ive got the plastic cleaned the frame painted black and the motor back in the bike with a new topend that's been ported and board with race performance stiston rings and pin and I bought oil for the bottme end and radiator fluid and gas so hopefully ill have it running in a week
