first kart!

The ground strap would probably vibrate and break because of the rubber spacers allowing flex.

 

[Buick455]

Your thinking solid strap. No I'm talking braided copper, like under the hood of your car. Engine block to firewall...

 

[jr dragster T]

Yeah I know braided strap. Still can break over time. Not as likely a real strap like on a car would break though.

lookin good so far man, mines almost done, just have to re do all the welds on it so its nice and strong and then mount the engine and brake disc n caliper.

sweet! i am just going to keep the wire how it is, and i have rubber mounts anyway.

Dont use rubber mounts, A solidly mounted motor will rev higher. Also a engine that is allowed to vibrate can do weird things!

Weren't those Russ's exact words?

 

[Kaptain Krunch]

Does someone want to explain why a solid mounted engine will rev higher? that makes no sense to me.

 

[r_chez_08]

same. on the engine mounting section on this website it says that rubber is not a necessity, but can be used? mine are just little blocks of hard rubber i found lying around.

 

[jr dragster T]

Its all about how the crank counter weights throw. For example if you have a video game at home with vibrating controllers allow it to vibrate loosly in your hand and then hold in firmly. You will hear and feel the difference. I dont know Kibble where those his exact words?

 

[Kaptain Krunch]

That makes sense, I've made tons of small rc cars and gadgets with little electric motors, and i have noticed that the off balance motors spin faster when they are held tightly, i guess i just never linked that with a large engine. Luckily i was too lazy to put rubber on my motor mounts

 

[brendonv]

yeh dont put rubber under it, u dont want the engine to move at all and with the rubber is will be able to move a lot. NOT GOOD! Especially when u got the chain hooked up, u dont want the engine going back and forth, might screw with ur chain.

 

[r_chez_08]

i will experiment with and without rubber blocks on the mount, not as a condom(kaptain krunch).
today i linked up the throttle and brake pedal. i am now thinking about a seat, helmet and harness. would this or this harness work with a tillet bucket seat? also does this helmet look suitable?

 

[Kaptain Krunch]

i will experiment with and without rubber.

don't get her pregnant.

couldn't resist

 

[r_chez_08]

shudup!!!

 

[r_chez_08]

so would the harness work? and what do you think of the helmet???

 

[brendonv]

don't get her pregnant.

couldn't resist

ROFL!!!

 

[r_chez_08]

to be done:
attach throttle outer cable to kart
buy a tillet bucket seat, or similar
drill holes for mounting.
remove everything.
paint
mount everything, including a harness. does this harness look ok???
buy helmet (do you think this one look suitable???)
go have a test run!!!

 

[r_chez_08]

i sent the guy a message, the harness should work. is there any way of lowering the rpm that the clutch engages at, as i think it will slip too mutch. i have also ordered the above helmet.

 

[Buick455]

I have been told if its a centrifugal you can change the springs, I haven't tried it before though.
