83 250r making 60 hp?!

[monster 84r]

hey guys, i decieded to post this for the air cooled 'r guys, and anyone else who cares. i was skimming through ebay, and saw an air cooled 'drag 250r' that cranked out 60 hp! the description says its been ported and polished, turbo rod, and reed spacer, but i dont think that would give you more than 6-7 horses. is it possible to make a 250r crank out that much horsepower? what about small mods such as reed spacers, reeds, filters, and other do it yourself stuff to push it a little farther? whats the best you could do for under 200$? oh heres the link to this crazy 250r.

[Dammit!]

I know 60hp is possible with a water pumper. Never heard of an air cooler getting anywhere near that though.

Just so you know, thats a 300 Kit on that motor also.

[nouseforaname90]

It says "Fresh 60HP Engine".. that kind of makes me think that they put a new engine in it that is 60HP.. but thats just what it sounds like to me..

It says turbo CRANK, that blows past your $200 budget right there.

That is a nice air fooler.

[sandpuppi101]

Very much possible,porting with 310 kit ,crank,redd cage,I am guessing without seeing the motor close it is stroked she's probably got 60Hp!

[Billy Golightly]

Hmmm... I dunno guys. This is an aircooler we're talking about. THey made like what, 28-30hp stock? Thats double the original horsepower without alcohol. I guess its possible but it seems highly unlikely.

[Blown 331]

I don't think that one has 60 hp. I think with the water cooled R's with a stroker and big bore from ESR or CT they claim like 70.

[TeamGeek6]

60 figured how? "Feels like 60" or did someone test it at 60? Does the word "dyno" show up anywhere? Sure it could make 60, thats not much horsepower. Just putting pieces on it doesnt make power though, it takes tuning.

Hey if all else fails al least it looks cool!

From my August 83 issue of 3wheeling they did a test of the stock 83R motor and then installed a 300kit. The stock motor made 23.5 hp and the 300 kit made allmost 28. They then put a Kerker pipe on and got 29.5 hp out of the 300. That is with a stock carb rejetted with the jet that comes in the kit. My 81 300R probably puts out 31-32hp based on that since I have a Kerker pipe, 35mm carb, no airbox,a K&N and a bigger intake with a boost bottle. Another 28 horses would be hard to find. I think about 45 hp would be the limit.

[TeamGeek6]

Agreed, but the "mags" arent gonna give anyone that serious of a horsepower boost. so they can go out and kill themselves. The mags are out to help parts sellers sell parts that the average mechanic / rider can install. They are not going to give out professional tuning advice.

Its a matter of hp per cc (or CID). Look at the top fuel mechs, 10,000 hp + out of 600 inches (?)

You should actually read some of the old mags before you open your mouth. They tell how to build a full race 200x, 600cc snowmobile engine conversions for Odysseys, homebuilt 2 strokes etc. Remember, this was before all the CSPC stuff but maybe you're not old enough to remember.

And yes, 10,000hp from 600 cubic inches but with forced induction and methanol for fuel. I don't see a blower or turbo in any of the auction pictures.

Just so you know, thats a 300 Kit on that motor also.I e-mailed him asking if it had a 300 big bore kit and this is what he told me.

(This bike is still a 250 bore. This motor makes awesome power. You have to spend big money to make a banshee out run it. The big cc four stroke drag bikes it has ran don't want any either.) I think he needs to wake up!! :crazy:

[Semo Tri Z]

Hey guys! Trust me! This bike pushes every bit of 60hp!!! He lives 3 houses down from me, I have seen it run. It has wicked power. The reason it says fresh is because he hasn't got to race it but a few times. Nobody in our area is drag racing this year so he said he was gonna sell it. If i had the money i would buy it for sure. Tell ya what!! My Z has wicked power, I will try to get him to line up with me in the next few days and i will get back to ya!!!

[monster 84r]

sounds awesome semo, i want to see the outcome asap, even better, a video :). i want to see this thing run. i would love to see all he did to get it that high, it must be insane with that much power, and on the standard bore?! crazy!

HUH??????????????????

UPDATE FOR YA!!!!!!! I lined up with this R last Wednesday night at the Butler Country Fair Dirt drags!!! Guess what the outcome was?????? My Z walked all over him. After i beat him the first to times he went and geared it up, then i beat him 2 more times. WOOOOOHOOOOOO!!!!!!!!!!!!!!!!

[monster 84r]

jeez, that sucks for him, mabe he lost because of rider error or ? how bad did you beat him? goot job on the victory though!

[Semo Tri Z]

I didn't beat him real bad. Couple bike links or so!!!

[firefirefire90]

that motor could be bored from 300cc to like 330cc plus an aftermarket crank adds like 10hp right? I mean many things he didnt list that he should have.
