Re: Anyone know the stock secondary springs?
If you have the new team clutches I don't know what you get, they are different. But for the older yamaha (except the G1) it works well to toss a umax spring in the secondary. I would recommend it to any lifted cart or towing with a stock cart. They are a little bit of a pain to get apart and back together but not terrible, its posted on here how to. The spring really helps lifted carts a lot and should not affect top speed. At lower speeds it revs more and has more zip. It would still hit 31 on the pavement. And they don't cost much either. With a BB you don't really need it, but it can make it more fun. With a clone maybe its nicer because they like to rev more than a twin, I put a clone in and it worked great with it too. But with a different primary clutch now the setup is much different. Some people with twin BB engines take them back out, they have so much torque they don't need any help.

Re: Anyone know the stock secondary springs?
I see plowmans sells a spring for the g29 so maybe it'll make a little difference

Re: Anyone know the stock secondary springs?
The plowmans stuff is good stuff no doubt about that, guy really researches or creates everything he does. Just saying for many yamaha if you don't have a big budget the umax is the ticket for some improvement and its a quality stock yami part.
The team clutches had some issues, if you have them you should read up on them. |

Re: Anyone know the stock secondary springs?
Yeah the stock clutch is stikn shut already, it usually won't restart the engine after the cart has completely stopped as it's trying to move the cart while it's trying to restart it. I have to tap it back open to restart the engine. I need to remove it and then try to get it to move freely again. Hopefully it'll last long enough after I try to fix it so I can think on what to do next drivetrain wise as I have a list of other things to do first like lights, paint etc before I decide BB or plowmans stuff

Re: Anyone know the stock secondary springs?
Some of them had recalls or updates but I don't know much about them, other than they had problems. Not sure why yamaha did that I know people with yami sleds from the 70s that still run and drive with stock clutches on them, yami knows all about clutches.

Re: Anyone know the stock secondary springs?
Not sure if this is 100% conclusive but today I had the umax spring I ran for about 2yr, the G9 (G2-G9) spring I ran for less than a summer and the tang broke off it, and the new G22 (G11-G22) spring I just bought. The G22 spring is about 1/4" longer than the G9 spring, of course the umax is significantly longer. But I was trying to see and difference from the G9 to G22 and sure looks like a minor difference, it would rev a little more a low speeds but not much. Will try to post a pic later. I don't think the springs would weaken in a couple years use but I know the old original '92 G9 spring in my cart now is a little shorter than the new one that broke.

Re: Anyone know the stock secondary springs?
Maybe the difference in the G9 and G22 springs has something to do with the old style and the upgraded spring seat??

Re: Anyone know the stock secondary springs?
Possible, I have the upgraded one but it looked the same size to me....didn't measure it. I put new cut sheave, spring, spring seat, and spacer on mine. But the umax is like over an inch longer so I am thinking 1/4" is barely going to be noticeable. Umax is thicker wire while the other two appear to be the same, I didn't have anything to measure the wire. That was about time the newer motor came out too.
I actually rather have the shorter one because my 94c revs enough on its own, but I don't think this will change it much. You also have like 10% variance in springs allowed (in the manufacturing specs). |

Re: Anyone know the stock secondary springs?
Have a photo of the umax, the G22, and the broken tang G9 spring. All been used less than 3yr or something the G22 is brand new. You can see the G22 spring is slightly longer but same revolutions of wire. I was thinking the umax was little larger wire too but I didn't measure here.
