in my sig you will see my project... its a 1990 honda 70 that i got when i was 5 years old... well i have gotten a little bord lately, and decided to try to put 2 chainsaw engines on it, strech it out, and put some jr dragster tires on it... when i was 10 i started racing jr dragsters and i have some old tires laying around, and i work at a family owned body shop and have all the resorces. i saw a classifed add in the paper for 7 cainsaws for 100 dollars. i have everything! the only thing i need to know is will it work? has anyone ever done it before or know someone who has? also i was wandering if there was a kit to put a tranny on it... might sound dumb but i thought it would be a fun little machine to ride!

 

how are you goning to get 2 engines running at the exact speed running one axle. i hope this doesnt sound mean to you but i think that wouldnt work

 

ya you would be better off puting a banshee motor into it[img]i/expressions/face-icon-small-wink.gif[/img][img]i/expressions/face-icon-small-smile.gif[/img]

 

well, if you attach both engines to the same shaft...sinchronized correctly, they will draw power off each other...effectivly working the same way as a 2 cylinder engine. as long as there both running right. dont know what you could use as a tranny....omm well, i can tell you from experience that "peerless" transmissions out of lawnmowers dont work well...maybe try to find a centrifugal clutch and put it at the end of your shaft...probly not gonna be too powerful though..

 

haha that reminds me i made a gas powered scooter out of a 32cc weed wacker engine and a centrificul clutch to drive the chain to the back wheel. it worked ok but the the clutch went.

 

stevo,

Forget the chainsaw engines. If you want something small and powerful to go in there and still remain light weight, you couldn't go wrong with a 80cc two stroke dirt bike engine.


Go with a CR80 to keep it all Honda.[img]i/expressions/face-icon-small-happy.gif[/img]

 

You might be able to make it work but it sounds very difficult. I'd go with the CR 80 motor like Knows said.[img]i/expressions/face-icon-small-wink.gif[/img]

Then again if your heart is set on it, go for it. My friend and I almost put a 550 honda 4 cylinder bike engine on a go-cart. I welded angle-iron to the frame to support the added weight but we never finished it. We always wondered how it would have ran. It would have been awesome. Probably something like 50+ hp on a 100lb frame.[img]i/expressions/face-icon-small-shocked.gif[/img]

I'm kinda glad that we didn't finish it.....we would probably have died on it.[img]i/expressions/face-icon-small-sad.gif[/img]

 

knownuttin, whats up with that staypuft icon? lmfao! that is the stupidest looking icon i have ever seen on here. he looks like a g@y guy trying to lure someone behind a dark alleyway or something. by all means leave it be. it fits you well.

 

how much for a cr 80 engine and tranny? how would i do the exaust? do you think i could get a pro circut or somthing and "make" it fit?

 

staypuft? That's not staypuft. That's the Michelin tire guy! Dumb@$$!!


stevo,

You can sometimes find complete CR80 bikes from the early '90s under a grand. They use the same engine up to 2001.
Get the whole bike and you will have the carb and wiring harness to aid in the installation.
