custom exhaust i made..

[vandancouver]

ok im building this go kart for my 2 kids..something for them to play with. we bought it complete with a engine, stripped it all down to nothing except the frame and started over. the proper throttle cables, brake lines, etc.."souped" up the engine a little, port and polished the heads..about it..
did a tune on the carb..and now i made this exhaust. is this ok?
it sounds TERIFFIC..seems like i gained a little torque..not sure.
here are the pictures.

the exhaust was smoking after i turned it off. is that normal? i kinda thought it was..not sure though.

also i think it looks kinda ****ty, but the kids love the "dual" exhaust type thing. they are 6 and 8..

The only thing i would worry about is the extra weight/stress on the exhaust port, make a brace for it and you would be fine.

looks aren't as important as function, doesn't look bad. should work fine

 

[vandancouver]

i dont have a welder and dont have access to one..what do you suggest for a brace?

also the thing seems like its so rigid it wont stress it out, but im sure when im driving the bumping does wear on it..so what should i do for a brace?

..so what should i do for a brace?

1/2" x 1/8" flat stock chasis/hose clamped closest to the end of the header.

Where do you hook the brace after you make it?

Where do you hook the brace after you make it?

On the flat heads we use 2 of the head bolts.

 

[EagleTalons]

Oh ok, what about with a 22 VM mikuni, do you add a brace there too?

 

[jr dragster T]

Lol, You dont realy need to brace your carb.

 

[EagleTalons]

It feels heavy though...

 

[jr dragster T]

Brace it if you wish. Measure the weight in grams on your mothers kitchen scale and let me know.

 

[EagleTalons]

I don't have a scale, I'll just let it hang out there...

 

[vandancouver]

i havent made the brace yet...
ok so i know this is the worst video ever..but i made one so you can see what it looks like.

your sure i need to brace it? it feels pretty rigid though..
but i will, id rather it be safe

also the video dosent give it justice..the thing sounds like a beast lol

if you park it anywhere but inside, make sure you put something over those, in case it rains. we always had to do this with the big V8's when we did the though the hood intake systems (we just used old bean cans, which work great.)

 

[EagleTalons]

We had a CAT that you had to place an old can over the exhaust, it was fun to start up with the can on it. Pop! Woosh!!!

Maybe you could build some cool flapper covers like some big diesel engines use...

I was thinking that pipe looks like convenient grab handles to push the kart with if it ever broke down. Unless you build a super strong support bracket, (and with all that leverage) you might wanna warn them kids that it could possibly damage the motor if they put too much strain on it.

 

[vandancouver]

i never built a support for it. i just left it as is..and pointed it down. i warned the kids. they dont touch it. i was hauling *** yesterday..the engine is almost stock..port and polish and a lapped valves is all ive done. i havent even removed the govenor because then ill need new valve rings to support the rpm gain
