powervalve has gone to spend the weekend with Dave

[sparx]

So the powervalve is having a weekend away at Dave’s for him to dial in the brand new pwk 28 carbs.
Spec as follows
Untuned 31k barrels
New powervalves and seals
Power dynamo mini flywheel and stator
Ignitech ignition
And the second set of Daves pipes ever made
Asked Dave to fit the RD500 kickstart that I’ve had over two years too
Just Don’t embarrass your self or me this weekend

Post the resulting graph up mate, interested to see at what rpm your power and torque peak.

[sparx]

Am sure Muttsnuts will post the results when it’s done

[sparx]

Never a good sign when daves sends you a text saying what you done to this bike it f**ked :-0

[shaunthe2nd]

Oh dear hope he sorts for you. Keep us posted.

[0h5h1t]

did he say whats foobarred mate

[sparx]

No says it did 35 bhp and wouldn’t rev. It has just had top end off for new powervalves and barrels repainted so powervalves might not be in right position. He will sort it

[0h5h1t]

hopefully just valve position then, they werent 180 out were they you think?

[sparx]

Dave didn’t say on phone but the bike made 66bhp same as it did before the new powervalves/seals and the new pwk carbs. Dave does say that it has a better power curve and accelerates quicker so I’m happy with that

[muttsnuts]

it was doing 62bhp before the PV's where fitted, its now doing 66bhp, and pulls better from 7k onwards

[sparx]

Oh I thought it did 66bhp before

[sparx]

This is the dynograph of when I first got the bike with some Nikon pipes. Standard carbs. Standard reeds. Standard ignition

[muttsnuts]

heres your graph (b4 aft the PV's changed)

[sparx]

Cheers Dave. You got one with rpm along bottom instead of mph
