Do you always run a slick on the dyno?

The figures would read higher with road tyres, as I understnad it.

I do realise it's an arbitrary number, used for tuning purposes only....but bragging rights is bragging rights man!

Yes. but only because that is what is on the bike.

I know that pumping the tyre up hard makes a little more power. Well actually looses less power climbing the hill. Road Tyre = more power, how does that work? less sticktion and/or deflection on the drum? any ideas.

Just less drag I think.

I was told about Chris Ozbourne (I think it was Chris, my memory sucks) tuning a supersport/F2 bike some time ago. It had been track ridden with a slick, or the rear rim had one already, but he fucked around for ages trying to get power he had previously gotten from similar bikes. Only changed the hoop because it got canvas showing from the number of runs he'd done, and BOOM, numbers stacked up.

Atleast, something similar to those events....I've made memory disclaimers many times.

recall reading way back about AMA roadracing in the 70's, Gene Romero qualified fastest at Daytona by having two front tyres on his Triumph. The reduction in rolling resistance/drag was enough to make the difference. Racing was of course done with proper tyres front and rear

How come everyone's 50's
have horsepowers in double figures

**F5 Dave** · 4th March 2014, 20:42

That's pretty solid, there'll be a bunch of fast 50s this year. Just put mine back together bar final adding water, fettling foot pegs etc. new ring, can see some light down the side so it won't be pulling the 14.3hp it has done in the past

. (I can spot a pattern). Well 10 years ago in 2004. It's only had rings, the odd piston and a bunch of wear since then. Oh and 10 GPs, a hand full of BoBs and a million club miles.

**TZ350** · 4th March 2014, 21:18

You have had good value, mine is a borrowed bike so I hope I don't break it.

**mr bucketracer** · 5th March 2014, 07:22

was told by Chris Ozbourne that he has seen 600s losing up to 3 hp with wets .. think its the stick of he tire when releasing from the tire . i did run my 50 up on a wet but some how dont think it heated the tire up .....but .3 hp bugger have i time

I'm still way behind with what's happening and of course I don't know just when the Tokoroa race day is.(this weekend?)
Seems that there is 50cc racing on there, - wouldn't mind seeing that! - I have never seen 50cc racing here in NZ, maybe I'll be able to make it there, with a bit of luck.

Thanks,
Will.
