not sure what the cart had for returning the brake and throttle before, but there was nothing there. so we added some return springs, and some pull limiters and stoppers on the rods. so you can't just press the throttle so far it breaks lol...

also had to to make a new rod for the throttle, it broke while i was trying to modify it

used a kill switch off one of the mini bikes original engines

not sure why i took this picture i guess you can see the stock muffler lol

gotta take the thing apart and hit the frame with some gloss black.

also this mini bike is the most fun of the two i have assembled, its weird how it has pretty good suspension on it

i found out that these springs are basically mountain bike springs, i bought one for $17 that is supposed to have 1500lbs of resistance or some shit. the difference is massive from the one that came with the bike

Got motor mounted, needed a bigger pattern but barely had room on existing plate

Can swap motors still

random-strike · « **Reply #38 on:** March 27, 2025, 04:34:50 PM »

Yeah it's fun I sold the little mini bikes and bought a new roller from gopowersports

The go kart is insanely fast prob 60mph lol

The clutch won't hold the power so you have to take off kinda easy once it catches you take off like crazy

It's faster than a lot of cars lol

It needs a "torque converter" cvt thing

60 on a go-kart is crazy fast!

The go kart is awesome

random-strike · « **Reply #43 on:** April 04, 2025, 02:07:29 AM »

Better throttle is really nice now

random-strike · « **Reply #44 on:** April 05, 2025, 02:28:30 PM »

Go kart is awesome lmao

I put a 54 tooth sprocket on and it lowered the top speed to about 40 just guessing but it doesn't slip the clutch at all anymore and just takes off like crazy spins the wheels when turning going fast around corners

I think something in-between the 42 and 54 I have. I bought a 48 tooth which I think will be pretty good. I think it does need a little more speed without revving out the motor. The governor is off but they arent made to rev extremely high lol

Also had to get a jet kit it lean bogs / hesitates on the hit and barely does it once really heated up fully after some rips

Needs some Allen head bolts cause of the tight space hope it sounds cool and not too loud lol

random-strike · « **Reply #47 on:** **Yesterday** at 12:52:39 AM »

Exhausts is cool, sounds good pretty quiet sounds like a stock 250 dirt bike

I also rejetted it and it's pretty dialed. I had a lot of problems with the bowl o ring gasket, I finally had to just silly cone it.

I went from a 104 jet to a 115. I think it needs a 120 or 125 but it runs a lot better

It hesitated a tiny bit on the hit a couple times where it was Everytime and would basically stop unless you eased in it

I'll probably put in the 125 I just don't want to take the bowl off again lol

This is the baddest go kart I've seen in person by far

It's going to look amazing when we disassemble it and paint the frame

random-strike · « **Reply #49 on:** **Yesterday** at 12:55:59 AM »

Also painting mini bike frame tonight

I got some primer on it, I was going to paint it red, but my dad joking suggested Chevy orange, so it's getting it

random-strike · « **Reply #50 on:** **Yesterday** at 01:23:33 AM »

It looks awesome!

Are you running a flag on the rear high enough to give full visibility for drivers of much larger vehicles to not run you over?
