what kind of studs and how many for 121's and 136's

[jtssrx]

Still a little undecided whether to go 96 or 120 in the apex.

Go with 96 and if you don't like it you can always add more.

Matt is right that's not enough. Your going to screw up your track.

i was leaning to the 120, and now i have made up my mind. Thanks guys.

It's nice to have reliable and knowledgeable resources.

hey BBY i was thinking about going with 2 place backers and the BIG NUTS with a 144 in the center pattern? whats ya think? should i just go 192, in just nervous about the ripped track problem last year.

Rule of thumb, 1 stud per HP...BBY

If he didn't sell studs I might believe him

Seriously, one of the rags tested (one of the good one's) studs a few years back and used a zr900 as the test mule. They put it thru all the paces, thru all types of conditions and were very surprised at their own findings that 96 worked the best. The 96 studs were worn about the same as the higher numbered studded tracks. There were no pull outs and they achieved as good and some times better hook up with 96. They theorized that 96 hooked up better becuase they could penetrate better. Kinda like laying on a bed of thousands of nails.
Your top end will suffer less too with the less rotating mass :ORC

I agree with Mighty 96 down the middle @1.325 is all you need for typical trail riding, which will give you good handling and good acceleration. Now if you are going to snow drags, then put in 1.375 stud @144 to 168studs and stud the outside belt and if you can afford it change it to a 1" track and go with 144 to 168 with 1.175 in stud. I had a 120 in my REV 800 down the center and it was actually too much. You don't want to have too much bite on the track, because it will throw the balance out on the sled.

The bottom line is do what your most comfortable with. I work on ALOT of sleds every year and see tons more pull throughs with less studs. Just going by experience...BBY

 

[BlueByYou2000]

It should also be noted that the less studs, the faster they will wear out...BBY

We had another thread almost exactly like this one (2 months ago?) where people claimed that 96 was enough. Then srxspec posted and said that even 120 was not enough for the apex. Allen works on sleds everyday and races and rides the trails. So now we have 2 heavy hitters Matt and Allen saying the same thing, and these guys know more than me (more than 90% of us actually)
I plan on studding mine in a couple of weeks and I know I will likely go more than 120

I also know that most drag racers like alot of studs.

Hello, Tork, Hello, srxspec is a drag racer :ORC

Got ya Dan, I forgot for a moment that you know everything and are so open to differing opinions :ORC

Just commenting on what I have learned in my 25 years of snowmobiling Tork

I think 144 up the centre is the magical number for the apex 150.
