Any Interest in sled engines?

opsled

Just wondering if there is much interest in sled engine swaps. It seems as though there isn't but I'm not sure.

The reason I ask is that is a large part of what I do for a living (sleds and engines) and could easily put together complete running engine packages of many different sizes, makes and configurations if there was a market for them. Fan or liquid cooled in HP ranges from 25ish to over 100.

What I consider to be a complete package would be an E-start engine with all the fuel/oil, exhaust, mounting and electrical components to run the engine and the CVT (clutch) system it was run with. Usually the electricals would be complete with harness and guages. Liquid cooled would require a radiator. Adapting (fabricating) the components to fit would be up to you.

Pricing would range from around $400 up depending on the engine. I've done many in the past but I'm not sure if it's worth my time to do them in today's market.

Here are a few examples of some of my past engine packages.

Any Thoughts??

Those look like some nice set ups!!

Are you knowledgable with clutching on these motors? I could use some help tuning mine

I bought my whole sled used for 250- 503 fan skidoo voyager . I like where you re going with this . tuning clutches and exhaust . would be beneficial.I think people are not as interested because of the noise and smoke. If you could offer some 4 stroke sled motors i think you might have more interest

4 Stroke sled motors are pricey.... would love to run the newer phazer 500 twin 4 stroke.. it's 2 YZ250F motors fused together and makes 80hp

I would be interested in that 485 phazer e-start motor if it's still available tho

Yes I can clutch but there are so many variables and many mismatch clutches on applications like this because of fitment issues. It can be a daunting task without actually seeing the parts/install.

Buying the whole sled is usually cheaper. If you have them near enough and know what you are buying that is a good way to go. The 503 is a good engine and a Voyager should have E-start. $250 is a good price if the engine is good. I don't sell junk engines but have bought many sleds with them in it. I check out everything I sell and many don't make the grade. You can get lucky and/or run into a good deal but often you get what you pay for and overhauls can be expensive.

4 stroke CVT engines start at 80hp and go up. You can't touch one for under $2000 with all the components needed to make them run.

The Phazer 485 is an awesome powerplant. 70 hp is easy to get and they run forever.

Here's your Phazer 4 stroke. Sold 3 of them to this guy for identical cars. He's the blue car on the left at the start. The only 4 stroke out there. It ran away from everything. Hauls a$$. It would be overkill in a golf cart.


Here's the guys site and the build of the 1st Phazer 4 stroke powered car. Some cool vids in there.

Bad ***!!

Here is what I am running:

1980 Yami Exciter 440 - AAEN Pipe (cut and turned by me) - Boyseen Reeds - little clean up porting - Wiesco Pro Lite pistons - stock compression - stock butterfly carb

Primary Clutch -- Comet 102-C - Unknown Weights - Pink Spring

Secondary -- Team Industries off of a Polaris Sportsman 800

EZGO Rear End -- 10.5 : 1 w/Limited Slip kit

This set up works pretty good and pulls REALLY hard out of the hole... I changed the primary spring from Silver to Pink (getting hard to find these) to soften up the hit on encagement. It was brutal and I felt I needed to soften it up to prolong the life of my rear end. It now engages around 3000 and takes off plenty quick for me.. its hard to launch on hardpack because wheelspin is crazy.....

What I would like to tune is the backshift to increase acceleration from 30-50mph if possible... Getting to 30 happens superfast then kind of backs off after going to full shift.

Is a spring change in the secondary something that could?


Thanks for your help!

Those EX 440 engines are bullet proof. Stock were rated at about 48 hp. With the Aaen and reeds, properly tuned you should be in the mid 50's and just as reliable.

That engine should make it's peak at about 7500 ish rpm. It's going to fall off after that and drop quickly after 8000 or so. That Team secondary should be adjustable. A spring change is probably not needed but the amount of twist on the one in there may.

From what you describe it sounds like the primary is close but the secondary may need some tweaking. The "Getting to 30 happens superfast then kind of backs off after going to full shift." statement leads me to believe it might be overreving. If that's the case you need to take some twist out of the secondary spring. This will load the engine harder and keep RPMs down.

It could also not be reving high enough and the first 30mph going quickly could be because of lower gearing. Without knowing more info or seeing it it is hard to say (to many variables).

Anywho, Try adjusting the secondary. More twist will raise shift RPM, less twist will lower shift RPM. You should be able to google the procedure for these adjustments on Team secondary.
