Yes it does matter, the side with the spring goes on the outside And the flat side inside

thanks so what your saying is i have it on wrong in the pics. i hope that is correct cause i will have to redo my plate if not.

here is my exhaust on it engine is a 10 hp kohler k241

 

[Bph30-06]

and has anyone here used or know of one of these k241 engines being put on a kart?

No it's backwards,thats why it's not alined,and nice exhaust system I kkinda want to know how it sounds

 

[Bph30-06]

thanks yeah i was hoping i had it wrong in pics . and thanks on exhaust it sounds pretty decent ill see if i can post a video of it in a min. you ever used these torque converters before. im running 23 inch tires and planning on a 6 to 1 ratio after converter.

No I haven't, had one of these before, so I don't know what a good ratio would be

ok not its no problem i have supply of sprockets at my disposal. you got any concerns with the frame or anything you see?

Nope everything looks great, and the frame looks very strong, strong than my frame Atleast and I have a engine twice as powerful as yours so I think yours should hold up very nicely

only thing ill probably end up changing is front susp. thinking of building some a arms in steap of the spindle setup i have now. it just seems to stiff now but gonna wait to see how it rides and handles.

I can tell you now, it's gonna be rough; one way to reduce that is to reduce the tyre pressure but, not too much, you don't want to be running on flats... or you can build a full dual A arm setup...

I can see a few minor problems with the frame; the frame itself looks ok (although, I would've used larger material), it's more the setup that may cause problems:

-IMO, the engine is a bit too far back; moving it forward a few inches will throw the balance to the front; at the moment, the engine appears to be directly over the axle, good for balance but, no good for handling...

-You may have a problem with routing the chain around the rear of the frame...

-Again, IMO, the steering shaft support is a bit too far forward; if possible, I'd move it back...

Other than that, looking good

 

[Bph30-06]

Yeah I agree with the front suspension I'm thinking of makin a arms for it but right now I just wanna drive it bad. Been working on it since last winter when I got the motor. And the engine is a few inches forward over center of axle. Not sure how much farther I can go with out redoing the rear swing arm frame. And yes its tight for the chain but clears with bout 3/4 inch for sprocket. How well do you think the live axle will hurt steering the way it's setup now versus a arms?? Thanks for your advice

Set up correctly, suspension will not effect the steering, what will effect the steering is... well... the steering...

What I mean by that is, if the steering geometry isn't set up correctly, it simply won't work correctly (that's the thing about mechaincals, they only do what they're designed/made to do); there's no clear shot of the steering geometry so, I can't comment on how it will work (hint hint )

Have a read through this thread & see how your steering compares...

As for drive ratio (sorry, I missed it on the previous post), IMO, 6:1 on 22s is a bit steep, especially since it's going off road... even with a TC

Is that K241 stock? That exhaust system looks heavy. I did not see any support for all that weight hanging out of the exhaust port. They have a tendancy to break out the exhaust port with out some kind of support. As all K-series Kohlers have a good amount of vibration, therefore furthing the cause of exhaust port break out without some kind of support.
