Does it matter what engine i use?

this might be the wrong thread, if so i apologize in advance

i just recently got a killer deal on a small go kart, it has like a 4 hp briggs on it currently but i want to put a blaster motor on it , I'm very mechanically inclined but i figured people on here would know more about which specific year blaster motor i should shoot for, which would be the best for my project and have the least amount of electrical issues?

thanks for your input

they are all the same, and u dont get much simpler than blaster electrical

unless you go for a dirt bike motor, like a cr500 I:I

A blaster motor will make that thing fly, but you may be better off running a Briggs and Stratton Raptor (flathead) or Animal (OHV) racing engine. You can find good used ones pretty reasonably priced and it will bolt right on. Less fabbing required and you'll still be pushing 15hp + with the right fuel and tuning. Plus these engines have forced air cooling systems, so keeping one from overheating is a whole lot easier than facing the same problem with a Blaster engine stuffed behind the seat. Just food for thought...

The kickstarter can also be a pain from the hybrids i've seen on here... Seems like something with an electric start would be much better for a go-cart...

is this an offroad go cart or a racing style?

Id stay awake from the lawn mower engines no matter how hopped up they are.The clutches suck and are expensive.Id stay with your blaster engine idea.I dont personally think you will have an issue on a go cart any more than you would on a blaster.And if you do fab up a couple scoops.


As for electrical all you need is ignityion unless its an offroad cart then id put head lights on it.

Make sure you post pix this would be awesome!!!!

You can find electric starter kits for the 5hp Briggs engines (13000 model series) no problem. While its very true that the traditional centrifigual ("direct drive") clutches burn up in a hurry and would surely fry when run on a race engine, all you'd need would be a torque converter drive.

Sure, you might lose a little top end speed with a CV drive, but it would allow the engine to put out plenty of low end power to get the kart rolling (even on hills) and still scream up top. Plus, that way you're not trying to engineer a remote shift system for a Blaster engine and there is no clutch lever or pedal for a novice rider to learn how to operate. How are you going to re-start a Blaster engine when the kart stalls out nose-up on a hill? You have to get out and kick it, of course. Is that really a good idea in that situation?

I'm not against swapping a Blaster engine into a go-kart; I just like throwing out other ideas and staying practical. Sure its a great idea on paper, but everything else aside, how fast do you really want to be going when one little jab to the steering wheel sends both front wheels hard over to one side or the other? (as the case may be on most go-karts w/o gear-reduced steering).
