Better engine alternative.. 2.5hp OHV

Post by 929rog » Fri Nov 04, 2011 4:14 pm

Had many of these kittys and 1 left for my youngest daughter. I never really liked the 2 stroke, its ok but only after buying the $140 mikuni 18mm carb. I was going to do the 6.5 hp conversion but It is very tight and a little overkill for a 3 year old. So I bought a harbor freight 2.5hp OHV "greyhound" engine for around $80 shipped (with coupon). With a pipe and turn the governor up some I have heard of 4+hp. Guys run these on motorized bikes. I ran it all summer ion a go kart and cant believe how strong it is. Pulled me on the Kart excellent geared for 20mph. Best parts of this conversion. 5/8 shaft, use the kitty cat clutch. The Whole motor fits under the hood, tank and all. Very east to install. Here are some pics. I am making the pipe this weekend. here are some pics

Been working on the brakes. Order a z120 brake mount that bolts to the motor and will work perfect. I'll have more pics whenever the mount comes in. I have a short video or it running but have not figured out how to get it on here yet.

You could put the vid on youtube and post a link here. Have any pics of the pipe before you put the wrap on it? Make any jet changes?

I dint have a pic of the pipe. Bought a flange from affordablekarts.com I think and has 1 inch pipe bent as tight as I could. Then just used a hardware store muffler. It will need to be re jetted. Its pretty lean now. Used to start 1st pull everytime now it starts hard. I'll get a video of it around the yard as soon as we get a little snow or the ground freezes.

I'm glad to see that you can do a motor swap because I have a 72 Kitty cat thats been in the family since new. The only problem is my oldest brother tore it apart after the orignal kawi motor blew up. Then he decided to loose half of the engine parts. Please post more pic's so I can get some more ideas.

You said your working on the brakes are you putting on completely new brakes? Cause my 1999 kitty cat just has a piece of metal around the clutch that tightens when you pull the clutch. The brakes did nothing when I bought it but I adjusted them to work in case I need them but being 14 I can handle driving a sled at 8mph

you can do the whole thing for under $200 with all new parts including the engine. I'm posting a video in a couple minutes. Got the brakes fixed. Bought a z120 brake mount, bolts to side of the motor and worked perfectly.

i had a really junk clutch on it. I just ordered the Hilliard extreme duty. It has adjustable engagement, it needs more. That cluch engages right above idle. Impressed with the motor and I had a stop on the throttle. So far.. Harbor freight 2.5 ohv motor $80 z 120 brake mount $24 Asuza brake band and cable $28 throttle cable $12 and now the $50 clutch.

Nice job, great info too!

I just bought a 73 kitty for my grand daughter and it ran for about 20 minutes. I took the thing apart and the list of parts I need are: crank seals, ign coil, lighting coil, clutch, and the reduction gear shaft is worn where the seal rides. Just some TLC ya know. We'll since the ignition parts are not available I was happy to see that there was an alternative that would put things in new condition. I am pretty sure that I am going to get the Harbor Freight engine and go that way. Thanks for the great info!

Snow fell and so did the Kitty Cats

Post by zerko » Tue Jan 17, 2012 3:58 am

I picked up a 1980 and 1996 Kitty cat, at are first good snow the 80 ran 5 minutes and clutch and track sprocket when out. changed it out ran it for a day and down again. I saw sparks down at the coil, looks like bad coil wire.
The 96 runs 20 minutes and die's . Well to rebuild these your looking at $50.00 to $100.00 each. So I think a 2.5hp OHV motor sounds good.
