If I move my engine mount down about 2" and over 1/2" I could move the seat back some more and have a lower center of gravity. I would have to move the clutch gear(needs replacing) closer to the clutch housing or move the axle gear over. Except for the cutting/welding/grinding, I see no downside. What do you think?

Phil, there's absolutely no reason to move your engine unless its to line the clutch up with the bottom sprocket. It'll make zero difference in the handling, and will be a great deal more trouble than its worth. There are hundreds of great handling karts out there with their engines much higher than yours. If you need more legroom, buy some Fox pedals. they move the feet forward over an inch due to their design. You could also add a "front porch" to the front end of the kart. Ted

im with tj., if your lucky motor prolly weighs 15-20 lbs with about or less than that  many ft. lbs of torque .......averg driver 175 ???    ill bet it dont matter where its at or witch way its pointing you might notice tiny difference if it were handing two feet off the rear bumper .. watch your sprocket clearance if you insist on movong motor ..i might have 11- 68 one week and 10-76 the next need lotta room sometimes ..

Phil,
basic math here.
kart about 100#
engine about 20#
driver about 200#
biggest mass is driver.
driver center of gravity is already pretty low the old time racers knew what they were doing.
if you put the driver any lower friction with you butt draggin on the track will become a big problem.:shock:

you wanna go faster add an engine.
you wanna get better handlng move up in the era year of the karts.

your kart is design fine as is and is what it is.
finally changing the frame radically will destroy any value it might have if that helps.

The general feel is to have more leg room. these karts were never meant to have leg room. I have one with a small front porch added but not enough to totally destroy the cosmetics of a classic kart. You may want to put it in the living room for a couple weeks and practice sitting in it to watch TV. That way your joints will learn to bend more. LOL

or take up yoga classes.
after about ten years of steady yoga practice you should be flexible enough to hop in and out of the kart with little trouble!!:cool:

Hey Steve W.,

LOL I did that when I was single. I would have my whole kart in the living room, sit in it to watch F1 races and tv shows. I did not have much furniture any ways and being single I did not care what anybody thought if they did not have a place to sit. Here are a few pillows to sit on the floor! LOL

Sometimes I grab one of my padded Tillett seats to sit in to watch tv. The wife does not want a whole kart in the house. She gives me a hard time just having a few kart parts scattered around my desk in the living room.

Get a rear engine or sidewinder Blackhawk kart. They have plenty of leg room. Dave L. is right, with plenty of practice and limber legs, you will be hopping in and out like a bunny.

Kind Regards, Joe

Hey Phil,

What brand kart is that? There were several brands with the axle running through a tube. The Caretta does it, I had a Hoffco Hurricane and a Traci\'mstupidhackerster that way.

To answer your question, I echo what Dave L. said. Personally, I would not alter the originality of the kart. I would leave the seat in its original position. You might try different positions of the engine without altering the original frame. How about mounting the engine UNDER the rear axle tube?

I see your clamps that hold the rear engine mount to the tube. Loosen the bolts. Try pivoting the engine back and down just above the road surface and see how it looks. That would lower the C of G. Then you might want a clamp on rear bumper to protect the engine.

Kind Regards, Joe

I am limber enough to put my feet behind my head with a little stretching. I would not alter the frame, just one of the engine mounts. The seat is held in place by set-screws, so it is adjustable, could move back a couple more inches if it didn't hit the starter assy. The current mount has been repaired rather sloppily and should be fixed anyway. The lower center of gravity is an excuse kinda like headers give you better gas mileage, true, but not the real reason you get them! I have NO IDEA what frame it is, wish someone could identify it for me! Oh, I thought of another excuse,err reason to lower the engine. Better aerodynamics!!

Phil

Phil, can you post a picture of the whole kart or have you already done that in another post?

But like Dave said, the biggest mass of the setup is the driver. Maybe a little more "lean" in the corners as was the norm back in it's day could help more than any actual modification to the kart. Just a thought.... :) -Alan-

It's not a Bug unless it's much modified. Once again, the CG is already lower than many karts that handle great. It is your kart, but if it were mine, I wouldn't be altering it for so little reason, and possibly destroying whatever value it has. I once had a dead axle Bug to which I added a Reed Engineering live axle kit. I thought it would be great to lower the rear end as much as I could, so I welded the new bearing hangers on top of the main rails. I ended up with 5/8" of ground clearance at the back of the floor pan. My friend welded his bearing hangers below the rails, and his kart looked like a jack rabbit. I still have a pic of his kart from 1961. After driving both Bugs, we couldn't really tell any difference in the handling. My friend, Lanny, won A Junior that points season with the jack rabbit against some stiff competition. TJ

Ted, your bud's kart mod transfered more weight to the front axle and made it stick better in the turns, I'd bet.

I dig that raked look myself.

If you could get a clutch with an inside sprocket and do something with the header, you could move the engine over and down by building a different mount.
I don't think it would be a noticable change, though.
Bug did not make an axle like that , Steve. I don't know what it is. You prolly have one like it some where in your barn behind all the tractors and snowmobiles and 55 chevys. Did you get your Apache running?
