To Speed Spring or Not

[Rotozip]

Hi guys. I am new to this forum but have been lurking for awhile. Really good info here. I recently got my first cart. A 2009 Yamaha Drive, 6 inch jakes lift with 23" tires. I ordered the speed spring but after reading the forums some more I am not sure I should install it. Do we have anyone that has used it for an extended amount of time and has reported it causing any issues?

Wow that's a nice cart.

Thanks!

I'm assuming you're talking about the stiffer secondary clutch spring? Not sure, but I wouldn't call that a "speed spring", more like a "torque spring". The secondary clutch springs typically are stiffer than stock, some more than others, which puts pressure on the sheaves and makes them more difficult to open/spread and shift. This effectively keeps the cart in "lower gear" and makes it easier to climb steep hills and pull heavier loads.

No long term negative effects.

The Drive "Team" transaxles have had some problems with the collar that the govenor fork rides on and can lose the "govenor effect" when it wears. I'm with gctech on this one, I don't install a speed spring on "The Drive's" anymore. Just my 2 cents.

Thanks for the reply guys. Yeah slonomo it is actually a stiffer spring you replace on the governor that I was wondering about. Smallblock right now I just have the 10 mm bolt cranked in some and it is faster. I think I will just keep it as is.

Usually a shorter or stronger spring. The issue is the spring pulls against the governor, your pedal pulls on the spring. The more pressure from a stronger spring and/or it is adjusted to a higher speed the more pressure is on every part from the pedal cable to the governor parts themselves. The governor just pulls the throttle off more the faster you go. A G9 or G1 will wear out the pedal cable much faster if you have the governor all the way up or modified to go faster, even though on a G9 there is not much difference from max to no governor. So if you take the governor off and put a throttle return spring on it takes a lot of strain off the cables. Some say take the governor out of the trans but few have any issues on older carts, the drive I don't know.

Thanks sho305 for that info. It's making more since now how all this governor stuff works on these carts. Since I did crank that 10mm nut in some I have noticed the accelerator is stiffer and I can see where that is putting more stress on the cable. I read I should adjust it to provide some slack where the cable connects to the pedal under the floor board.

Got it. I was thinking about the secondary spring. LOL.

Me too!

We change springs & helixes all the time on this little setup:
