The sleds are a torque monster. So it’s what you want. Out of the box, (you might know if you had it before the turbo ) pulled hard to 75mph then seem to run out, then the other 10 to 15 mph was a slower climb. You now have added hp and clutching to have the hard pull to 105 mph. For my...

Big difference in original and updated. Should have been a recall. But nope I changed the primary weights to 60 gram. I did that before the gear change because I was bumping the rev limiter at WOT on rail beds. So the weight change and 24t top gear change is spot on. Do yours up! U...

P Pro, I have exact same sled and same year. Just did mine this fall and love it. Just changed top gear to the 24 T and left bottom gear and installed the new 92p chain. I see no different in low end and gained 5 mph on top. Another 1. 5 miles per gallon when cruising. I had same...

At the end of the day its a gear box. So when turning the out put with the 21/49 sprockets it takes 2.333 turns on the in to make the out turn one time. With the 24/49 it takes 2.04 turns on the in to make the out turn one time. So with rpms the same it gives me the extra track revolutions...

Stock viper and xf 7000 are a 21/49 that is a 2.33 ratio to 1. If you are running a 24/50 that is a 2.08 to 1. If you go to a 21/41 that will put you at 1.95 to 1. That will help your top end. I am not 2.04 to one and its where I want to be for what I do.

I have a xf 7000 with the Yamaha motor. I had to replace my actuator. When I got if from cat he said new part number, meaning they have been upgraded since mine was put in at the factory. My sled is a 2014. I see no physical difference. Installed it last week, so early to tell, but it works...

Yammitrip1. Both come stock with 21 top 49 bottom. I am now 24 top and left the 49 on the bottom.

Ok, I said when I got my gear changes I would give you all a update. I did change just the top gear. Went to a 24 top gear and left the 49 tooth on the bottom and had to change the chain also. I can say it is spot on for what I do. I was looking for more top end. Tried it on the dragged...

Connondale27, Thanks for the reply. You have been a big help posting some information on end results. Not the smallest of jobs to change gears and would like to only do it once. LOLOL Of course I had to do the cover because of broken tabs on the 2014 chain cover. I am like you I ride...

So are you running the 25/45 set up? If so you are now at 1.8 to 1 ratio. You were at 2.33 to 1 stock? (21/49) That's a bigger change then I am making. I am going from the 2.33 to one factory to the 24/49 with a ratio of 2.04 to 1. You are saying you are ok on the bottom end?(that was...

So, Lots of people have asked about gearing including myself on this thread. So gearing to 21/ 41 or 24/49 has anyone got any results? We all agree we are gear low at 21/49 factory and agree the sleds pull great until 85 MPH. I just did mine and left the bottom gear and did a 24T on the top...

So you feel not much binding if the belt is that old? ( I know the clunk u talk about). Also I have never blown a belt. As I said I was hitting the rev limiter until I put in the 60’s weights. But back to my original issue, it seems like I am running out of gear for the riding I do. I ride...

Savage man! I will go in that direction for sure to start. Thx so much.

Stock is 21 top gear and 49 bottom gear. 2.33 to 1 ratio. So geared for low end pull. If I do gearing I think I will leave the top gear, the 21 and go to a 41 in the bottom. That would put me to 1.95 to 1 ratio. But will do the torsional conversion first as the guys have recommended first...

Ok, I may want to start there before purchasing a clutch kit?

Cannondale27, Thx for the reply and the info. So I understand what u are saying about the vector and I agree. But in my issue u feel there is some secondary clutch binding? ( I know they are noted for that) and I should go there first? If I go that direction I assume I will need a clutch kit...

I am new to the site an just want to say this is a awesome forum. One of the best I have been on for information. I am a xf 7000 owner and have been reading about the gearing guestion. I also experience all the things you guys are talking with my 2014 xf 7000 and was going to the in the gear...
