Had my bike dyno'd the other week.

Here are the results:



I've got to say I'm pleased, at least that it wasn't down on power.

Nice one, I heard doing topspeed runs on a dyno whilst stationary can really bugger your tyres up though because of the lack of cooling?

Is that RWHP or at the crank? It doesn't say on the chart ...

I can't see the chart (work) what are the figures?

Possibly true, I know that carbon fibre cans can suffer from lack of cooling and melt! I would insist upon a fan being directed at my can if I put the bike on a dyno (sure to happen eventually).

What happened at Lydden then?

I was warned about that by PheonixNW the uk yoshi supplier.

Even more so you have a baffle in.

About the cans? Yeah - I have a Yoshi (CF) and in the literature it says dyno runs invalidate the warranty :S

Mind you it's from the US, don't know if I really have a warranty anyway...

I would be very very careful and speak to the dyno operator to check they realise the risk...and what they recommend. After all the can is a 'race' can, surely it's going to be ragged/tuned at some point!

TBH The idea of 'Race can' is a bit of a gimmick. The power gains to be had from a can alone are pretty tiny and not really worth the dyno costs unlike setting up a full system, which bang-for-buck would see bigger returns.

Ok let me correct that - 'race system' - happy?

It's the same can on the slip-on & full system so it's still the case that it's silly for them to think it's not going to be used hard...

In actual fact I am buying the rest of the system, should pick it up at christmas as it's in the States.
