What primary and secondary clutch kits would be best for my 03 Viper SXV?


There are a lot of clutching set ups in the tech section you can access from the home page. Great wealth of knowledge there. While not a clutching pro by any means, what I can suggest is an alternative. If you want to run faster in the trails and such, you will gain far more by suspension mods than clutch mods. Trails around Port are typically crapped out . Better shocks and skids will get you going alot faster than clutching will ... and your back will thank you for it .

Why not do both? Clutching isn't too hard, nor expensive, if using the clutch setups on the tech page. Clutching is not only good going faster, but keeps the motor in it's zone. so It's better for the motor.
 
I'll definately have to check that out tonight. I'm from port Perry area but the wife's father lives up in Maynooth just north of Bancroft. So I'm going to be up there a lot of the time as long as they have snow lol. I'm defiantely curious about the suspension end of it as well. My buddy has an 04 and put a Polaris skid in his. Says he loves it.

"Clutch kits" are a generic setup to sell to the masses. Find a used rx1 helix and add some weight to the primary with stock Yamaha rivets to get the rpm's around 8400.
 
You can't go wrong with heelclicker clutching. It's a little pricey up front but is well worth it when you want to fine tune your setup. It sure beats drilling and grinding rivers when you can change screws and washers.If all your looking for is a harder pull corner to corner you may be better off gearing down in the chain case. Yamaha clutching is pretty good from the factory. If you want a little harder back shift you can add a hole of preload in your secondary. In fact if your couch has never been serviced and the spring took a set increasing the spring wrap my bring back lost performance. Not that you can go test now, but once you have snow on the ground a good baseline is to go and do the magic marker test. You take a black sharpie and make a line radially on the primary clutch from the center out to the lip. Go ride the sled then come back and look at the clutch. If the magic marker isn't wiped off by the belt you are never reaching full upshift and you can reduce the number of teeth in your chain case. It's standard to reduce the top tooth count by 1. If you have the room on an open field or lake make some wot passes too see if your shifting out at full tilt boogie. Most sleds in general and yamahas in particular are over geared and will never shift out. In the ideal world you would reach full shift out at your shift rpm and then motor your way to peak rpm. Oem's over gear the sled so they never fully shift out as a way of preventing over revving and blown motors. In short study clutching theory now, do some testing when there is snow and make adjustments with what you have before changing parts. You might be surprised what you can achieve before throwing money in parts at it. And remember no "clutch kit" will be perfect. You will still have to dial it in and might find yourself frustrated by money spent and naught gained.

Heel clickers are the choice if you plan future mods you can simply add weight. They are $230 and then you need a helix dalton is what I went with they are $130.
 
Be wary of that RX-1 helix it may not produce the results you want. It didn't for me on a stretched mountain max. It's a progressive helix not a dual angle and thus the angle is always changing. Don't forget to follow the rule of change 1 thing at a time so if it doesn't work you won't be chasing your tail. It's tempting to make multiple changes at once but if it didn't work your guessing what the culprit is.
 
So glad I joined this forum, I have a feeling I'm going to learn a shit ton from you guys on here lol. Thanks for the info. Very helpful
