Grand Daddy build

[coyotebait]

Motor mount works nicely. Tight clearances with sprocket but I think I can get a big enough sprocket in there once all is said and done. Additional 5 inch stretch on the swing arm seems to fit the bill with clearance on the seats on big bumps.

Mount steering column, throttle cable, brake line, and install proper hardware and she'll be ready for a test drive.

Then to finish up:
Roll cage
Seat belts
Install battery box
Install head lights
Install winch
Run electrical
Paint


Let me know if you have any questions/comments!

Thanks,
Matthew

got sore neck checking out that photo.

Working on shortening the rear bottom shock mounts. Thought I'd give you a picture of progress

This pic shows modified shock mount and caliper mounted.

Keep goin'

The easiest solution is to cut the tabs off the brackets, bolt them to the shock with a thin washer between the shock & one of the tabs (to provide a small gap to make fitting easier) & reweld them to the base plate. Tack them first then remove the shock, you don't want to melt the rubber bush...

Another note on brakes - I initially put the MCP master cylinder behind the pedal so that the pedal pushes on the lever.. it doesn't work well, as in, you'll bend the pedal before you put on enough pressure to lock up the wheels when you're moving. I called MCP to ask them if I should put front brakes on but they told me the hydraulic caliper is rated to stop a 700lbs racing kart so it should be enough if I mounted it correctly.

I moved the master cylinder to by the driver seat and used a rod - connected low on pedal to high on lever for maximum leverage - and now it easily locks up the wheels.

My speedo wasn't working but I was probably doing 30-40mph and the caliper was fine. Pretty hot after burning around the forest for a while, but fine.

Thanks for the info! I did mount the master cylinder next to driver seat with a connecting rod to pedal. Seems to work well. Haven't bled brakes yet. Glad mcp told you 700 lbs. I am sure with 2 adults and the weight of the cart I should be below that. But not by much!

I have run into 2 issues that are delaying me.

1. Mounted steering wheel too low.
2. Seats are too close together so I will have to redo mounts for passenger seat.

Should run tomorrow. I will put up pics tonight.

Oh and wouldn't you know, I was one link short on my chain. Figures! No worries though replacement is headed to my house tonight.

First 2 pictures show the winch mount.

3rd picture shows winch mounted.

4th and 5th pictures show the rear of the go kart with master cylinder mounted, seats mounted, seat belts mounted, and rear shocks resting in the modified brackets.

Thanks and let me know if you have any questions or comments.

Love the shocks! I used the ones that were specified in the plans and they work ok but bottom out easily - where did you get them from?

Lol. I used the shocks the plans called for and they bottomed out with my son and me sitting on it! I got these from an atv. I think if you read back in my thread I said which atv, right now i dont remember. Either way I just started reading atv specs to find some that would be close in dimensions.

polaris sportsman rear shocks are a good heavy duty one if you've got a heavy kart/buggy. that's what i use.

 

[Mballen13]

Will be out of town. Back on the project when I return. Idler sprocket will be here when I get back so the chain tensioner can be fabricated and then test drive. Wanted to test drive before leaving but parts didn't arrive in time

Cheers,
Matthew

Well it's been a few weeks have you got to test it yet.

 

[Mballen13]

Tested it. 9:1 gear ratio seems about right. Have a few things to trouble shoot and then need to weld on roll cage and paint and final assembly. May be a bit before I get the final product but I will post pics when it's done. Maybe a video too.

Thanks!
Matthew

Sweet, on the home stretch then...

So, what, no pics?

Yeah, we like pics of the build as well as the finished product
