Thank you for your kind words!....for the header I just make them for the engines I build, They are really not that hard to make.

Nice!

Thank you!
Thanks to all that likes this little Tecumseh, I enjoy building them.

Rocco,what are you going to put it on? needs a home...….

Yep, that is cool. Nice job on the header- serious bend. I need one of those exhaust flanges for an intake.

Yeah they have a cool look all their own.

Don't have anything to put it on...Its on a shelf in my basement.

I think this header will have a very nice sound to it.

I did a header on a Tecumseh h35 motor. you really have to make it close to the motor, or you'll burn your leg. Looking at Rosco's motor, i don't think the header is close enough to the motor. Typically you put 3.5hp motors on smaller bikes that don't have a lot of side room. here's the one i did, you can see it's pretty tight to the motor, and bends back to the center position of the back motor side. I'm using 7/8" stainless steel and a custom flange to make it work.

I like the smooth transition in that bend Rocco. Nice and short, those Tecumseh really thrive with less exhaust, and you didn't reduce the exhaust diameter by trying to get the pipe so tight.

I like it too, but if you burn your leg while riding, it doesn't matter how fast you go, you still have a bike that is less than ride-able. Also on a 3.5hp motor, i'm not really sure how much can be gained from an open exhaust with or without tight bends. it's probably less than noticeable.

This motor is not on a mini bike to even worry about that....My builds are not for everybody an there are front peg mini bikes out there that you would have to be trying hard to burn your leg on my header. I have made other headers for these types of motors too, yours looks to fit real nice in that frame.

are you saying this motor goes on a go kart? because then that exhaust would be really perfect.

As I stated earlier this motor is sitting on a shelf in my basement but could be put on a mini bike and rode by someone. if you dont like the pipe thats fine but keep your comments to yourself. Ive had plenty of mini bikes in the past with pipes just like this and never burned my leg, maybe your just one of those kind of poeple.

I love that header ! Also I would run that Tec engine on a mini bike in a heartbeat .

Rocco, I like to here what it would sound like with a full built 6000-7000 rpm motor.
just wish we had someone here that could build one....lol..
if we had enough people comment to racing a flathead this year at symco we could have a modified flathead class....
