So I see Goodwin is offering some ramp options and I believe they are Doo ramp profiles but does anyone have a profile comparison or pictures of the different options?
Thanks!

I have a set of 951's and 967's. No difference in profile between the two. 951 has more material (weight) on the underside towards the tip.

From what I've seen, just like Illinoispowder said the profiles are the same just more or less weight.

Complete different positions on the adjustable clicker.

Print, cut out, and lay them on top of each other. Eyeball only, says it looks different.

Something is a tad different with that 968 ramp look at the gaps of how it sets in the box
I have the 967 and 951 ramp and I thought it looked like the 51 ramp rolled out a tiny bit different on the top but I could be wrong.
I have the 960 ramp as well. It has much more angle to build more rpm through the shift for the 600rs I can't see if having any use in the mountains on big engines.
What about the 964 ramp? Any pictures of it?
Thanks guys!

So let assume the 967 and 968 are the same profile. How would the 7 with enough pin weight to be the same as the 8 compare?
Could the 968 be an alternative for those of us with over revving problems? How about running the 951?
Perhaps combining the heavier ramp with a shorter bolt to achieve something in between.

the 951 is a lazy ramp IMHO...
the 968 is a better ramp IMHO-BJ

I agree with the 51 being lazy...engine is LOADED all the time.
968 Looks to be similar to the 67 profile but possible roll out harder on top plus it's heavier.
Only issue i see with using any of the heavier ramp versions in the 850 is you will no doubt have to unload the bottom of the ramp (take bolt length out) and I'm pretty sure most of the slip is happening initially during the first 25 percent of the shift.
No 964 ramp info? I ordered a set but won't be back from Mexico for a few days to check them out

How are the adjustable spi ramps working out John? Any other adjustable ramps available?
Do you have any ramps we should be playing with?
Thanks!

Is a 968 going to work above 8k?

No way to know till you try it.
But looking at the 968 I think it's going to act similar to the 967 just heavier but then push harder on the top. So I think it would be a little much for stock sled at 8k feet.
I could be off on that though

Witch Ramp would you choose between the 951 and a 967 with added pinweight for doing tree riding/technical riding at 0-2500ft?
I'm seeing a lot of guys saying the 951 is a bit lazy, how is the 967 in comparison?

Most of the slip in this clutch is happening at high trail out speeds. My better halves clutches had blackmarck from a 10 mile trail out at high speed bewtween 3/4 and 7/8 on the primary, black as coal from ruber build up. She likes to go fast but runns more of a constant rpm and speed. I go wide open from corner to corner and mine was clean as a wisle.
I have a sealevel primarry spring in mine now, that is about the same RPM difference as 3 clickers. It got me down to 7900 to 8000 with much improved shift in and drivability.
With the heavier ramp one can probably also go to the heavier secondary spring and get more belt grip all around.
Ultimately I believe the heavier secondary spring will be needed to maintin backshift with all the extra weight that everyone is using.

Stock ramp 38 mm stock bolt.
Weather is warming up and support to dump a couple feet of heavy stuff for the weekend will do some heavy snow testing a bit higher to see if I could run more weight.

Ran it with stock pin + 1,1 grams and lighter primary spring.
Secondary all stock loading the engine hard.
7800 to 7900 went up an other 100 RPM as I got out of brake in. Snow condition was heavy coastal pow.
It out climbed the stock setup feels more responsive its not huge , but has a slight edge.
The lower engagement is nice but you have to watch it it is easier to smoke the belt getting unstuck it comes on real soft.

What spring are you using?
