Keystone19 Race Report PMCC 7 May 2006

[Keystone19]

Cheers guys.

The bike came with the slicks on so we thought we'd give them a go this weekend in the dry even though we ran pilots last week. Both me and Motobob had the same lack of confidence on the slicks and he's never run tyre warmers either.

We took the pilot rear off my road bike which was fine as a one off last week but I'll get a new set before the KB track day for the race bike (credit card limit not withstanding). With a bit of luck that should solve a few problems and be a good tyre to run through winter.

I'm not planning to do the Vic club winter series - maybe one race - but Motobob will probably do F3 on the SV.

Cracked me up a bit at the weekend on the slicks though, takes 3 laps to warm them up of a 5 lap race, kind of amusing really...

Oh, and Frosty, that's 1.12's at Pukekohe on my street SV...

Im just a little worried that as your riding skill and speed increases, you might outdo the pilot powers as they arent a track based tyre... I highly recommend Supercorsas as they are a shit load better in the wet than racetechs...

[motobob]

The reason for the use of slicks is advice from Shaun. As you guys know the sweeper tears up your tyres, Shaun felt the slicks would be a better option but do need warmers.

The rear slick has a similar wear pattern to my Super Corsa's so the tyre is being worked. But the slick was still slipping on the grid markings entering the last turn yet the SC's didn't strange!

Cleve Brown is running PP's and these show little wear at all, He is pushing the R6 along at a similar pace to my CBR yet our tyres look completely different at the end of the race.

Frosty, K19 will be kicking your butt shortly so watch out.

racetechs and rain......not cool....not cool at all....!!!!!! agree totally bro...

tearing up a tyre can be the tyre.....can be too light spring rate.....can be not enuff rebound....and can be the surface.....but if others arn't tearing up there tyres on the same track....on the same tyres.....my guess would be rebound....and may be spring rate to soft....although if the tyres not hot enough that could also be the problem....

[Cleve]

My understanding is that if the tyre isn't tearing up too much (and you are NOT falling off through lack of grip) then you have your suspension pretty much sorted...?
Still I would like to see a bit more wear on my PP, it kind of worries me that they don't rough up much at all.

I don't really know jack shit about suspension on bikes however... I did have a Supercorser on at Taupo, the left hand side was tearing up and leaving big strange patterns on it the same as many others are getting. Then on Sunday I ran slicks, the slicks have no sign of tearing up or any wear on them at all, pretty much just smooth all the way around. ... for what that info is worth or tells you about suspension setup I have no idea!

Hmmm but you were getting damn low on the slicks and you didn't fall off...
Also I noticed Sam Smith's Dunlop road tyres looked smooth as well...
hmmm no still don't have a fucking clue myself. Maybe some master like Shaun will read this and spread light...

[vtec]

I found that I was ripping up my tyres because I didn't have enough air pressure in them. That could have something to do with it, but it could also be suspension.

cool wight up keystone. good to see ya out there & sticking with it

[Keystone19]

Great photos BabyB! Thanks!

[FROSTY:Me]

Dunno if it'll help cos every bike is a bit different. I had my first crash at turn 1 of the old track.There is no question as to what happened. Even running 26 pounds in the front my tyres were still stone cold and smooth as a babys bum -no balling up at all. There is no feel for what the tyre is doing. -I pushed too hard and the tyre just said--BYE BYE
Dougal noticed that even the F2 guys were running wets --Ie a very soft tyre in the dry.
I think the weird wear pattern is partially caused by the tyres being too cold and literally ripping away from the tread grooves.
I'm thinking a soft compound PP ROAD might help in that the tyre has heaps more grooving so the treads can flex and heat up better/quicker.

[Keystone19]

Have decided to go with the Pilot Power for now but will also be looking at suspension settings with Shaun at the KB track day. His feeling is that it may be too stiff in the rear for my weight which is contributing to the lack of heat in the tyres as well.

Looks like you may have to visit Burger King more often to help the tyre situation
