Track day at Circuito de Cartagena

First time at Circuito de Cartagena on 78 Z650 lot of fun!!. Next year want to do some races if money allows me. (This year put a lot on my 77 Z1000)
I need loss weight, racing seat, cams, and 18x2.15 front wheel to cacth 110/80/18 Avon AM22. Probably Z1R wheel.

Looks like a lot of fun.
The 650 sounds good too.

Hola Leitz

good on ya, about time you hit the track

dont know what classes you have in spanish classic racing, but here in italy a 650 would fall a bit short as the class is 750.

all you need a block and pistons from a 750.

Some teams are starting to run kz750 also in classic endurance, getting good results.

go for it, you will not regret. track days are nice but real racing is a different story

Hola TG!! i know and my sights are set on racing. New regulations for 2106 so i´ll wait a bit.
750 Block and piston is better than 700 Wiseco?
750 offers you 810 in the future...

well, if you are going to run in the 750 class anyway, you might as well go full 750......

my racer was built around a gpz750 with a 810 wiseco kit, but even if this season has been my best (finished second) it wasnt really a match to the better open class bikes (up to 1100)

you have indeed to check your regulations. if the 750 class has a cut-off of 1979 (before 16 valve CB750F/GSX750 ) then a 650/750 will be very competitive. it's a much better bike than sohc750 GS750 . IMHO

here the 16 valve 750 have to run in open class as 750 max.
