Very fast modified/built Manco go kart !!!

I have many hours of work to this renforcing frame(fabricating by hand), making it a live axle, putting on briggs flatty, and installing a mechanical disk brake. Thats the extra short version of what I did. In this video when if first takes off I'm sure that you notice the lag. That is because of the high performace camshaft that doesnt "turn on" untill bout 4000rpm. In this video you hear it kick in about halfway through the first turn (when it starts roaring) lol
Tell me whatcha think!

you should do like a walkaround vid. i really wanna see the live axle. i have the same cart just 1 seater and am thinking about going with a live axle. but i love the ol one wheel peel, gives me some excitement i dont think a live axle will?!

@hondaman07228 If you can do it right I would switch to the live axle, its worth it. and it just depends on how much power you have lol. If the grass is anything more than slightly damp I cant drive my kart because it will just sit there and spin with the slicks.

[hondaman07228]

@JensenSteamEngines ya, i think im gonna. i got a briggs fun power, which is basically the same as the raptor that i plan to beef up. the live axle will benefite me im sure. i gotta get my motor tuned in though, it cuts out in my yard

[JensenSteamEngines]

@hondaman07228 There are some differences with the Fun power block versus the raptor series, most notably is that the fun power is what they called the "cool bore" which is aluminum, versus the raptors and I/C engines which had cast iron cylinder liners, giving significantly longer engine life. I would at least run a I/C block with a cast iron liner if you plan on doing any modding.

what engine? very cool! im makin a 125cc, 4 stroke, 4 speed go kart with slicks

[JensenSteamEngines]

@Boggle122333 Briggs Raptor III which is based of a 5hp flathead briggs.

[1967GTO]

@redneck9507 well at least now you just stated you were wrong. Tests have been conducted during testing billet cranks where they went over 12,000rpms. maybe a bone stock engine might not be able to rev over 5000rpm but the engine in this video is obviously not stock.

[redneck9507]

@1967GTO yah the drag ones ill rev ALMOST 10000 RPM

[1967GTO]

@redneck9507 Try telling that to the Jr. Dragster crowd. Im sure they have billet cranks, rods, and flywheels just because they want the inside of their engine to look shiny....

[redneck9507]

@1967GTO they don't rev over 5000 rpms buddy

[1967GTO]

@redneck9507 haha you obviously know nothing about briggs racing engines

[redneck9507]

4000 rpms bull shit... it prolly tops out at 4000 rpms
