Good day guys,

I need to know the cheapest way to get my Viper's revs down by 200rpms. I am still pondering if a clutch kit would be worth the money? Will I be happy with the stock setup with the rpms brought down to 8400 range? I need some feedback. I am ordering some parts asap. I can't decide on what to do with clutches. I do know I don't like how its shifting now.

Thanks

Troy
 
Yeah. I guess I really want to know how much weight to add to my primary and in what spot to bring the rpms down to 8400rpms ?

Thanks

Troy
 
top speed.. she revs up to 8600rpms at full shift out. It should be running at 8400rpms I understand.
 
Do as Tom said and add some tip weight to the 2nd hole in the weights. The stock viper weights have a very good profile overall, so adding a little weight to the stockers is definately your best bet.
 
If you are pulling 8400 - 8500 throughout shift, and only going up to 8600 at full shift out with the stock engine and gears, you are about as good as it gets. Your engine is making good power. You may modify your clutches to get overdrive. Might be worth 1 -3 mph.

Seriously - it will help you waste $300. You will get much better and cheaper results from the guys on this site. As others have said, try some tip weight. I believe there have been several posts in the past about replacing the stock tip rivet with a 4.5 gram rivet. Try searching the forums - there's a ton of good info. :rocks:
 
Thanks for the replys guys. I could not find that post again. So I would add 4.5 gram weight to the tip ?
 
I'm no viper expert but I know that the following setup from the tech pages has been used extensivly with good results:

53/43 Helix, Green Secondary Spring & Everything else stock.

In some cases where there is still over-rev a 4.5 gram rivit is used in the tip.

Maybe Turk will chime in on this question. He is the master.
 
53/45 makes everything fine. A lot of overrevs are caused by either an old belt being used or centre to centre being too short.
 
Now this is just me,but the 53/43 w/green spring didn't work for me. In fact I haven't found a multi helix that works for all around on the Viper. We have two in our family. We both run HH's now. Our center to centers are perfect and I've tried different belts too. One we could get the R's down(Dad's) by adding some tip weight. The other(mine) didn't matter how much we loaded the stock weights, so in went the HH's. We eventually went to HH's in the other to keep the comparisons close to the same. We both run the stock 47 helix w/ silver springs. I think we might try putting the Yammie weights back in the one that liked them and compare it again to mine w/ the HH's this winter. Overall I have been happy with the HH's because I don't have to constantly tune them once set. I think the Yammie weights may have been a tad stronger. We'll see this winter if it ever snows.
