there were heaps of these in SA through the 80's, very propular bikes. no doubt Andy Haydons win helped boost sales of these bikes in SA.
so the early jap models had power valve? the first couple australain models didnt have this. how did you get a jap model? the sales brochures/suzuki australia ads i have of the 84 model never showed a disc cover fitted. i almost bought one of these a few years ago for about $800 but once i arrived at sellers place he said he just sold it to someone else. you used to be able to get a fair bit of stuff to make these bikes better. WP shocks/shock spring, fork springs, HPF mufflers, Twin air filter, Boyesens etc. Trevor Flood specialized in selling aftermarket parts for these, and even sold them set up with this gear fitted and ready to go. Good knobbly tyres were also a must needed change.
there was even a watercooled TS 125 but not every states got them.
