I'd avoid riding on 15 year old tyres ....................................
leaving everything else behind in a blue haze
the howl of a 2T coming on song
the 'respect' just owning a kwaka gained, in any group
the thrill every corner held, and the smile after 'safely' negotiating it
the joy of crossing cat's eyes at speed, and not being able to cross back again
and the final thrill some years later, watching some dumbass spotty young tosser who had bought an old 500 as they were cheap, give it a handful at Boxhill (UK) to show off to the crowd, and flip the fucker over![]()

Fired the old girl up today. The two outside cylinders fired up nicely but the centre proved uncooperative. A few issues namely persished seals in the petcock and carb float bowls suggested that testing for a spark may be unwise so we left the electrical possibilities alone. We found that the bike ran fairly well for about 10-20 seconds at a resonable idle but then it just 'took off' ie the revs shot up for no apparent reason.
Each restart experienced the same result - initial stable idle but then a uncontrolled increase in revs.
Tinkered with the card slides, idle settings etc but in the end called it a day.
Anyone with ideas as to why this is occuring?
Could be anywhere obviously. Get a can of CRC engine start...spray it round various ares. When the thing goes mental you've found your leak! Maybe base gsk surfaces...inlet rubbers etc. Could be why the centre cyl is having issues...cntr crank seal. Can't remember what type they are...labyrinth seals or what.
...do yourself a favour and one of the most beautiful jappy classics ever, a break...strip the carbs, and you know without questioning that the crank seals are fucked...for fuck all money , if you cant be fucked doing it yourself, someone else will, change the seals, fix the air leaks in the intakes and make the poor unfortunates that cant have one of these , breathe easy...
Came to the same conclusion. I have rebuilt a ton of these back in the '80's but my heart is no longer in it so the bike will be put up for sale as is where is for someone to do exactly what you suggest. As a matter of interest, the carbs were the first thing I stripped and cleaned hence the relatively simple startup after 20+ years.
You can now breathe easy.
