yamahurry!

This build is going to be my racing mower build. I'm going to be mixing a yamaha 200 3 wheeler and a murray. Heres just a pic of the murray rigjt now.

That's gunna be awesome!

well like craigslist fashion the guy fizzled out. so my question is what motor/ driver terrain should I run? maybe make it a peoples build.

Anyone have a suggestion as to what power plant I should use? I'm interested in doing a high performance onan build to using a crotch rocket engine.

To me the crotch rocket motor would be really awesome, I'm putting one in my golf cart, the 3 wheeler motor would be good for torque

prolly end up trying to find a 600 to a 1200 cc bike engine and go stupid fast haha

Yeah I'm putting the cbr1000 in my golf cart

sweet! I'd like to see that when ur done.

Yep will do

Please remember to upgrade the steering and front axle when you are going to be going fast. Death sucks.

lol trust me ill be making sure its capable and safe at higher speeds

and brakes... It's MUCH more important to be able to stop when the speed increases

I've transplanted a lot of motors into a lot of different toys. I do think that I'm happiest with the built 12.5hp flatty that's close to the original motor that came on my tractor.

I like the electric start and that it functions as or better than stock. More power, more speed, but still a lawn tractor. I guess it depends on your purpose of your build.

If I want to ride something with a 500cc 2-stroke motor, I hop on my dirt bike.... If I want to ride something with a 1575cc v-twin I ride the harley. But sometimes I just want to ride a flathead Lawn tractor.    

ya im thinkin a vertical twin cylinder engine modified to run on methanol or alcohol.

Look for a kawasaki CSR 750. Great motors!   

that I shall ty for the tips

look for a Honda magna you can find them very cheap i owned a V45 750cc and it would get up and go later on a dropped in a police engine from a V65 honda magna and was just a crazy bike after that so all in all for speed i would go with a honda magna V65 there not so cheap but reliable

So can I get as much power and speed from a vertical shaft engine as a horizontal shaft? Which is better for speed application

both produce the same power. however, if youre doing a race mower, it depends. if you want to do a chain drive and engineer your own axle, use a horizontal. if you want to use a transaxle with a vertical input, then youre gonna want a vertical shaft engine. it all depends how much work you want

and those would be horizontal shaft? Also would a live axle from say a go cart stand up to the power of that engine?

Sorry I replied to first page lol. Work doesnt bother me but I'd prolly use a live axle from bmi would it explode using say a bike engine? Or should I just try and soop up a twin? I saw this one shops build of a john deere doin crazy burn outs and it had ridiculous speed. I messaged him and they said it was a modified 23 hp briggs!

Ive been searching but cant find the right words lol. Anyone have info on dropping the seat to where the fenders are higher?

hello?

The axle wouldn't explode from the power. AS with everything, more power means you use larger chains, axles, etc. Solid axle is stronger than most geared differentials. the hey is starting from the motor, and work the power back to the wheels.

ok. But do u know how several ppl have dropped their seats in between the fenders? Looks slick im just trying to figure out how its done and how I should begin doing it.
