My dear old Sport is now my trackday bike and sometime road bike.
And it is a hoot on the track, barring 16" rims of course.
And finally the 39mm FCR Keihins with no choke circuit
have come into their own.Have been trawling the site and have had some interesting reading about tyre and rim sizes, am in the process of converting mine and using Monster 620 wheels which will run 120/60 Front & 160/60 rear and they are a 4.5" rear, it curently has the oversized Bridgestones 130/70 & 170/70 (which runs very, very close to the chain indeed can barely get the tyre warmer fitted) on the 16" rims, which are fine for road but useless on track.
They are plain and simple just too big and wont let the bike turn in properly at serious speeds, I use to run a '07 Honda 600RR as my trackday bike and could just shut the throttle off tip it in then wind it back on for Turn 1 at Eastern Creek here in Sydney, which on that one is fairly fast motoring, once made the mistake of looking at the speedo and nearly ran off the track in the time it took to look,
with the current tyres on the Sport, actually have to drop a gear and brake doing at least 80 km/h less too even attempt the corner, 'pose you would call it oversteer, so will be interesting to feel the difference.The point of that ramble is it is very easy to overtyre bikes thinking more is better, it is not really the case, long ago (1980's) I use to race a 125 GP bike with incredibly skinny wheels and tryes and it was amazing how far over that thing could be cranked over, as well as a BMW cough, cough, 650 with a very worked motor running a 120 rear, same story.
As original Fairings are unobtainimium if it gets chucked down the road, have had a old school bevel SS fairing made without the huge round headlight hole in it for it for track use and am still hunting for a solo seat to suit it, got a bit carried away with the fairing, will now have to get yet another for track use hence the attached photo's.
Andrew2 is to blame for the idea by posting photo's of an SS fairing sitting on his Sport when he got it, looked at the SS seats, frame is to wide to make it look right.
I love it, looks old school, but without the Bevel Drive heartache, yes I owned a "Drama"
Anyways enough long rambling from me, will post some more pic's when it is finished.
