Dunlap 208 GP separation question

[GSXR RACER MIKE]

This was happening in 1987 when I started racing with Dunlop K591's.  It isn't a problem.

If you want, change to Michelin's.  That's what I use.  Thank you, Tom Mason...

     Man there's a blast from the past - K591's - I had those on my '86 Ninja 900R!

     (Shameless Michelin tire sponser plug to boot - sign of a true veteran of the sport! ;) ;D LOL)

In 1987, I started racing on a GSXR750, my first bike.  When I went to my first race, I had a K391 front and a prototype K591 rear... ;D

never had an out of round or hopping tire from michelin. hell, some of them don't require weights. fantastick tires.

p.s. the fronts are amazing.

[Super Dave]

Actually, they seldom require weights.

Unfortunately it is not as simple as just switching to another brand of tire or else I would have already done so.  In any event, I need to do something.  I'm running low on wheel weights.

I saw one that came back from a track day and the guy road on it even though you could see down through the crack to the cords.  He didn't seem to notice it while riding and said the bike didn't feel any different so I guess it is "ok".  My personal feeling is that the Dunlop dealer would be walking kinda funny with a 208GP shoved up his butt after telling me it was normal for them to do that.  Luckily for me and him I don't (never have and never will) run Dunlops on anything.

I understand.  The separation shouldn't be an issue.  

What's the date code on the tire?  Did you get it from Sport Tire, Jim Allen, or what?

I finally got off my butt and went and looked at the rear 208 on my bike at the moment.  Badda bing.  Lovely split right accross the center.  :'(

Got them out East.  1701 1801.  Not fresh but both wear and traction are up to typical Dunlop standards.  Roughly 10% have done this and it is hit or miss.  I am unable to tell any difference between those that do verse those that do not.  :-/

PS The FUSA at Heartland will be interesting.  Got suspension? ;D

[Super Dave]

Kevin Elliott told me about his visit to the track...

It's a whole lot different than the last time we were there.

Thanks Ray Irwin...

The good news is that Ray and Nancy are dedicated to bringing Heartland back as well as being extremely motorcycle friendly.  

The bigger cracks with the infamous sealer have been cut out and repaved.  There are still some sealer strips that are dicey as well as the white paint line that is 6-8 inches from the track edge and is slick, particularly at the apex of T-8.  Which really hampers going through T-9.  As always the drag strip sealer is ice in the morning.  Overall the track is extremely bumpy.  In fact ther is a nice little ramp at the end of pit out that when hit right can give some air.  Can't wait until repave.
