Gates ltx g-force belt

Not for sure but I'd assume both gates belts have the same grippy feeling to them, I've noticed with mine is it doesn't wind up as quickly as with the stock belt but rather it grips hard and really grunts the engine.

8dn slips hence the quick wind up. If the other belt grabs with less slip the motor should grunt and lug more. I am new to yamaha and 4 stroke clutching. I have a nytro. Is that what you are running as well?

I loved the first 30 miles or so with new scrubbed belt and clutch sheeves. No slip all grip!!! Have you guys done any secondary clutch machining?

I turned a 8dn into cat tail dust! Worst shredded belt I have seen in 30 years of riding. Left me stranded on trail with only belt wires left. Clutch alignment was just done.

Belt wires were all in and around clutch sheeves, helix, spring and anywhere else you can think of. Man that was a bitch!!!

Had to take secondary all apart on the trail or there was no hope. I have a ultimax belt now as well brand new and 8dn as well. I want to try these and other being a top notch belt is key with good clutching.

I had gates make a limited run for me on Kevlar water pump belts in the past. So curious to learn more about the drive belts.
I plan to do more testing with this over winter. I honestly don't think these clutches allow you to shift into overdrive like they should hence the machining. Lots to look at in my eyes.

More grip less heat and less left wet foot syndrome hence clutch heat melting snow dust only on clutch side leaving you with ONLY a left wet foot.

It would certainly make sense, I'll try to remember to grab my old mans heat gun when I go out tomorrow, that will be some other good numbers to know.

Why the heat gun? I assume to warm clutches and belt before testing like tire warmers at the track?

Sorry I meant a heat temp gun to check sheave and belt temps after a few runs, I just assuming that the 8dn belt is slipping because of the quick wind up, if I changed some clutching I'm sure it would do it as bad, but simply putting it on with the clutch setup for the gates belt it did not work. Even just putting around the yard the grippy gates belt didn't make it harder at all to ride as my clutching is set to engage right at 3000 rpm so it's very smooth at low speeds. Snow is still on the ground and the wife is shopping all day so I know where I'll be:)
 
Have you tried clutch machining or 14.5 rollers?
 
No I haven't, I wanna get what I can out of stock clutches and then possibly do some stuff in the future. Was out playing all morning, had the gates belt, 8dn and 8jp, all ran very similar rpm at top speed so speeds wouldn't vary much if any with the clutching I was using. One thing I do know is the gates belt grips so much harder than the 8dn or 8jp. I need to swap my aggressive helix out for the stock one if I'm gonna use the gates. So, running 1000' the fastest I got with 8jp was 101, 8dn got 103 and gates got 108 so a very noticeable difference. Running on dirt still but there is some snow of top to help some. Will continue to play more with it with the stock helix and see how that acts.
 
Do you have a part number for the gates belt? Ever tried the ultimatx belt?

Did you do another run after the day with the 8jp belt to see if it still run 101,just curious if the track got Faster or there is really that much difference in the belt

I actually started with the gates belt on, just ran back and forth a bunch in the field just making sure numbers were all good, didn't do any radaring at first. After that I switched to the yamaha belts and went from there. Very little snow, ground wasn't frozen and the more we ran the more it got tore up. The 8jp and 8dn would've actually been run at the fastest time of the day. Once I started focusing on the gates belt we ran it more and more and it just turned up all the dirt, by the end of the day we were running on sticky mud/dirt.

So no real definite answer then.
It could be the same or the gates belt could be a lot faster
 
Had I switched back to the 8dn the speeds may have changed, but I already gave that the benefit of the doubt and did the radaring at the 1/4 mile mark (1320 feet). When I radared it with the gates belt I was only running 1000'. Yes I did run it the full 1/4 mile with the gates but after 1000 feet it did not gain as it hits rev limiter, it took the full 1/4 mile to run the 8dn up to 103. These aren't good true top speeds as I need to change the helix out as the one in now is too much, but as for clutch settings the only change made was removing primary weight to get the gates to rev properly, the secondary wasn't touched so it's a good true comparison
