gokart from scratch

[jamyers]

A kart uses jacking and chassis flex to lift the inside rear tyre off the track and help cornering. Jacking can be increased by widening the front track and adjusting the front suspension geometry.

Thanks for the links, we are gonna test the new steering tomorrow hopefully and gonna see what happens from there.

 

[DS13]

Well we got to run the kart today and learned 3 things.

1) castor has been fixed, stering is a lot better!

2) some how the toe on both wheels is messed up. About 1/4 of the wheel on both front tires isn't touching the ground.grrrr

3) clutch is better but not perfect. The problem is if I'm in neutral and shift to first my engine dies, but if I powershift to first and move around and then hold in the clutch going to second the clutch works and doesn't move the kart.... its an adjustment problem but with all the adjusting we have done it still hasn't worked correctly. Any thoughts?

If the engine's been sitting for a while, the plates may be stuck together; a bit of driving usually separates them, otherwise, you may need to pull the whole assemby apart

 

[DS13]

you may need to pull the whole assemby apart

NOT AGAIN!

As ya said running it will help and it has today we ran it and the clutch worked better tomorrow hopefull it works even better.

So a couple things more to do and she should be done

 

[Ericpach]

Cool build!

 

[DS13]

Well clutch works still have the toe problem but have a solution in the form of bushings I'm gonna make Monday.

Here is me taking the kart for a test drive.

Looking good - apparently the clutch is working better?

 

[DS13]

Yeah its work a lot better. Fabroman said to run it a lot to lossen up the plates and it worked! Clutch works great.

You have a Kart capable of doing 100 mph faster test next time?

 

[DS13]

You have a Kart capable of doing 100 mph faster test next time?

Theoretically. (Wrong spelling I know)

Wouldn't try it unless I had a death wish.

whats the gearing count? im still trying to figure out what mine should be at.

how do you feel the speed / torque is.. im trying to drift with mine but wont mind 75 mph top speed

It looks to be about 4 to 1 (48 on axle, 12 on engine) iirc. I can check tomorrow and PM ya. I haven't really opened it up yet and I haven't really even hit the powerband so as soon as the steering is completed and a couple of other things happen ill be racing around the school like its my job

im just getting anxious to just slap mine together.

Yeah when I finally got it running and drivable I had the shakes after I was done riding it.

Do you have a sprocket yet?

 

[voided]

No sprocket yet... Ordered a 40mm 26 tooth then found out i have a 1.25 axle.. So I spent 12 bucks on a part I can't use.. Still trying to situate wether I'm going with a 520 chain - 12 tooth and what ever rear or 428 chain - 17tooth and 26 rear

 

[new-guy]

please keep updating this. I am planning on building a frame almost identical to yours and putting a 92 rm125 engine on it.

 

[DJEEPER]

Gearing looks way too low by the sounds of it haha.

Cool concept though

Yeah I will. I haven't really done anything major lately but I should probably do an update soon!

Thanks. The gearing is probably a little screwy but at this point its good for tests and does get me some good speed.

UPDATE AS REQUESTED:

Some progress has been made (not as much as I would have liked due to a manufacturing project we had to do for shop).

1) found a permanant spot for the gas tank beside on the top of a piece of solid round.

2) seat and harness have nee installed (see pics below) it is a lot more comfy now!

3) the donuts have been laid down!
(I can get a pic tomorrow)

4) chain guard has been welded together using some 10 gauge stainless although I haven't attached it yet.
