can anyone tell me anything about this motor i know its a POLARIS 300/295 CC 2 STROKE MOTOR THE ENGINE # IS EC29P any idea on power output or how well they hold up it seems to be in pretty good shape i think if i can get my carb problem fixed it would fire right up got good spark and good compression i tring to decide if i sould stick with this motor and get new carbs or should i swap out for a honda 400cc ohc motor putting out about 48hp ive researched parts needed (axel,sprockets,chain,hubs,ect) for the swap to be around 200 bucks do you guys think the 2-stroke 300cc or the 4- stroke 400cc any help would be great

That looks like my Polaris 295; and you're right- they're not too easy to find specs on. I've been haunting the numerous vintage snowmobile forums for info. I'm guessing they put out in the neighborhood of 30 hp and on my clutch, it says max rpm is 7500. One thing I have found in common about the motor is that everyone agrees that they are almost bullet-proof. If I were you, I'd just give the carbs a good cleaning (there are rebuild kits for pretty cheap in you have to go that route). Also- hopefully you have the other parts from the sled it came from also (clutches, etc.) If not- all is not lost- just a bit more expensive. See that shroud above the exhaust manifold? That HAS to be in place, or you will have overheating.

Well i can tell you it is an oil injected 2 stroke.

How much is it going to cost you for the 400 honda? I would go with the honda.

I Already Have The Honda If You Look In The Backround Of The Pic Youll See It

If all the honda engine is there, then use it.

I Have The Whole Bike The Honda Came Off So I Have Everything As Far As The Electronics Go Its Just Hookin Up The Motor To The Axel And Mounting The Motor I Dont Have A Welder Or Know How To Weld So Thats The Dilemma I Do Plan On Using The 400 Down The Road But I Want To Be Able To Ride While I Save Up Or All The Parts That I Need



**** I Just Want To Start Riding This Thing Already

 

[JUST8420]

Jerry Assburger I Was Wondering If You Send Me Some Pics Of How The Fuel Lines Are Hooked Up And Also Is There A Seperate Tank For Oil Or Mixed In The Gas Tank There Seems To Be Vac Ports On The Carb But Then Again Maybe Be For Oil Any Pics Would Be Great

Without welding, the sled engine would be easier to attack since you can make some bolt on brackets easier. Overall the bike engine will be better in my opinion, Dont get me wrong, i love sled engines but its going to cost a decent amount for new carbs, and bike engines are just as fun as sled engines (shifting is sick).

What size carbs are you looking for? i got 3 42mm (i think, there somewhere around there) that i'd be willing to sell.

 

[JUST8420]

How Much?? Send Pics
The Carbs I Have Have The Were Cast With The Mounting Flange On It Already So It Are They The Same Set Up Mukunis Ill Post More Pics Tonight When I Get Home

The Kart That I Have Had The 300 On It All Ready So Its As Simple As Bolting Some Carbs On And Firing IT UP... Hopfully
AND PLUS THE WHOLE DRIVE CHAIN SET UP AND GETTING SOME ONE TO WELD EVERY THING UP WOULD END UP COSTING ALOT MORE THEN A SET OF CARBS

just looked at the pictures of your engine and mine would not work at all, they are very different from yours. They mount differently, and those look a bit smaller.

 

[JUST8420]

Yeah Ive Found A Ton Of Mukunis For Cheap But Dont Think Any Will Really Work Without Fabing Some Flanges For Them And Praying They Seal
I Cant Really Rebuild Cuz Some One Drilled Out The Jets And One Float Bowl Is Cracked

 

[Kaptain Krunch]

i cant even find the same carbs

do you know if most mikunis use the same style jets

ill pull them apart and take pics of the damage done

 

[Jerryburger]

I take a picture tomorrow for you. It's pre-mix. There's a fuel pump on the back of the block, that splits gas to the 2 carbs. I'll take a picture and post it ASAP.

 

[Kaptain Krunch]

if you measure your flange, you may be able to find one meant for another engine that adapts to the common mikuni carb.

heres one for a harley, doubt its the same but thats what i'd look for.

make sure you either bring one of your carbs or at least get measurements.
