New to the forum, but not to go karts!

[2SlickNick]

Okay, rims are shipped. I will p.m. you the tracking code.

Hey Nick, do you know what your go kart's gear ratio was when you got it? I was thinking 12/72 but not sure. Thanks!

The clutch was not the original, but it was a 12 and the axle sprocket is 60 something.

 

[OzFab]

12:72 is perfect...

 

[Doug L.]

Yeah, according to BMI's speed chart, it's exactly what I need!

 

[Doug L.]

Hey Nick, I got the rims and they're fantastic! Just need a little sand blasting and bearings and they'll look great! Thanks man!

Good to hear. Make sure you start a build thread so we can see your progress.

 

[Doug L.]

Hey everyone, sorry it's been awhile. Had a lot going on. I finally got a chance to work on my murray again.

Here's where the original axle bolt broke off.

Sawed off

And welded on a new one

The fine mount plate had been badly cut into by the former owner

Filled em in with weld

Grind smooth then paint

Using Nick's rims I pressed in new bearings and removed the blue paint

I was wondering if someone could tell what that thing is for in the picture below? Part of a chain tensioner?

Thanks!
Doug

Pure conjecture here. ....but....with the location. ...and the corresponding rust on the brake rod.....I'd say it was part of the brake system.....

 

[Doug L.]

Oh that's not rust on the brake rod. It's dirt.

 

[2SlickNick]

Great job re-welding! Glad it is working out for you. I do believe it has a rubber idler wheel or something similar on that one mount.

here is a link to our exact model.....

That's what I thought! Do I have to have that? If so, where can I find one?
Thx

I have mine but it is dry rotted some. you could use an old skate board wheel and cut and chisel out the center or use one from a baja doodle bug.


or maybe one like this...http://www.ebay.com/itm/RED-Motoriz...Parts_Accessories&hash=item589d34baed&vxp=mtr

Hey, it appears there's more to the assembly than just the roller.

Do you have any of these other parts? Are they simple? Maybe something I could make?

I found a site who sells the roller: http://www.quickieparts.com/go-kart---mini-bike-parts/1001187-murray-go-kart-idler-pulley.html

Thanks Nick!

[2SlickNick]

I looked but couldn't find it. You could easily make that.

 

[Doug L.]

Thanks! I believe I will fabricate one.

 

[Doug L.]

Well, BMIKarts has a replacement for $90. Think that's the way I might go and reinforce it.

I decided to just get two replacement arms from BMI. These are noticeably better made. The materials are heavier gauge. Can't wait to get these painted!

 

[Doug L.]

After looking a bit closer I noticed on one of my swing arms the brackets to the chassis were only welded on one side. The other was welded on both so guess it must've been a Monday mornin mistake. I simply welded it myself.

Now painted

Here's where they'll hang for the next five days while the paint cures.
