Have we got dyno bench experts on here?

This is what my Kat pressed onto the roll today:



135,8 hp with 110 Nm

Specs:
1230cc EFE engine
ported head
Stage 1 web camshafts
RS 38 carbs
K&N oval pods

When I shut the throttle the engine always needs half a second to get back to idle.


Comments welcome.

Thats good hp, you must be happy with that

Hi Pedda, weldone on the big power, you must be happy with that, with regards to the RS38" carbs I ran them for a few years on my trick efe,. I loved the noise and the look, you have to get used to shutting the throttle quickly with your hand. In the end I changed mine a month back for Bandit 1200 carbs. To be fair I think as a road going carb the CV ones are better, more friendly, IMHO.

Yep decent power is that...

if that is just a power run in 4th it might be worth just seeing what the fuelling is like at very low throttle opening RS flatties as with any carb need a lot more setting up than injected stuff. Running over on shut off usually means it's running lean or the throttles are sticking (weak springs/one spring used instead of 2 to try and lighten them). Looks pretty good though.

Thanks guys,

The dyno runs have been made in 5th gear. The carbs are run with a push-pull-assy to make sure they always shut securely. I already did some tweaking on the mixture screws butt no joy. I think I'll check for air leaks once again and start from zero.

Hi Pedda,

I forgot to ask you if you are using the V&H 5 degree advancer ?

Yes, I do.

Pedda,

If you can't find an air leak and you have adjusted the air screws (max 2.5 turns - out ) and there is no significant change then you might have to increase the size of the pilot jet. I believe that a 17.5 jet is installed in your carbs.
