I have a problem with my 2014 Viper, first I got my #*$&@ handed to me by a 600 Polaris and that is driving me nuts. I can't get more then 8460 rpm out of it and a top speed of 73 mph. It has a MBRP race can, airbox mod , clutches have been tuned and I have the EVO flash. What's the deal? Anyone got suggestions.
Retune the clutching. You are WAY off. You need between 9000-9200 rpm. What clutch kit?

What model Viper? You may not be geared either.

Thats a big track.. you need to lighten up the clutch kit.. OMG, should be able to hit mid to hight 80s all day long.
I wonder if it was clutched for trail? Deep stuff with that track will really kill it

You say clutch is tuned. What do you mean by tuned? Is the a clutch kit in it? If so what kit. Weights are too heavy. Need to pull weight from tip to get rpms up. Where is secondary wrapped? Do you know what gearing is in it? 2-1/4" track is hurting top end big time. If it is geared stock, that's a lot of track to pull.

As was stated 3 times already. Your "tuned" clutch has too much weight.
Since you did not post any further info on what is done to the clutch for tuning, all that can be advised is to remove weight. Your rpm's are too low with that evo reflash and mods.
Post specific details of your tuning and someone on here will be able to tell you exactly what you need to do.
Untill you give specifics, your help will be limited.

As was said above you clutching is way off. It doesn't sound like you have clutch tuning experience so the easiest thing to do, and the thing most likely to yield success is to buy a clutch kit. They don't cost that much, they're easy to install and this forum is full of recommendations. I went with Ulmer but there are plenty of others. The vendor you choose can give recommendations for your specific application.
