adjusting powervalves!

[Vector88]

hey

i have a question about adjusting the powervalves. does i use the same allen wrench that i used to loosen the 2 bolts on the housing to put between the housing to measure the gap? it says 2.5mm but i think the wrench i used to take the housing bolts out were 4 or 4.5 mm. let me know if i uses another wrench to measure the gap between! well anyway i used the same wrench that i used to loose the 2 housing bolts to measure the gap between the housing for adjusting the pv's. let me know if i have to use a different wrench. i will adjust them over if i used the wrong wrench!

thanks

re-do it,, you used the wrong size,use 2.5mm

Yep Start Over 2.5

 

[ryanryan]

Yep you have to uses the 2.5mm wrench

so i dont use the same wrench i used to loose the bolts on the housing? ive been adjusting my pv's like this for the past year. would i get more power if i move them down to 2.5mm?

Your cables have been too loose, so the valves aren't being pulled open all the way. Do you watch your rpm's very closely? I'll bet you'll see a few more rpm's on top end now. Don't know whether you'll feel any "seat of the pants" improvement or not.

yeah she revs at 9000 would that be the cause? ill adjust it with 2.5mm now!

your over rev'en too by 500 rpms....unless your not stock.

shes at 2.5mm now and she feels much better. she has a bender 4x4 ceramic coated and boyesen reed pedals

u need some clutch work, get those rpms down to 8400

 

[Vector88]

clutching is all stock and all new parts was from cb performance parts! i was looking at a dyno for a viper and your not loosing no power from 8500-9000.

 

[redsnake3]

i dont really believe your not loosing any from over 500rpms, but either way it will be stronger if you throw more weight in the clutch and get it down to 8400

 

[Vector88]

i dont know why it would be revin at 9000 if my clutching is stock. was like it with my stock pipe and only mod i had done was boyesen reeds. and im sure that wont boost up the rpms to 9000

 

[redsnake3]

vipers tend to overrev from the factory, that plus any wear on the clutch parts will do it too.

 

[redsnake3]

also, just cause its stock doesnt mean its best.

 

[daman]

outa the box they over reved(viper,sxr,srx)

what would be a good set up for me? she revs at 9000rpm and 21-40 gearing. 8dn-10 weights, green-white-green primary spring, 15.6 mm rollers, green secondary spring.
