I didn't do stuff all either. First thing I did was put duct tape on the tank and guards to protect them  ::), Boyesen reeds, better set of bars to replace the standard licorice and change the fork oil. My bikes would look very plain. Shit actually with the red duct tape on it.

Simplicity was part of the attraction back in the day. Maintain it well, keep it mostly standard, ride it all weekend and do it all again in a weeks time. Little fuss or bother and no major rebuilds on the side of the track just so you can say that your bike is usually very reliable. Oh for those good old days.    :'( :'(

Fox Shox. Quite simply, a set of Fox Air Shox not only transformed the handling of my 79CR250RZ to be ultra adjustable & predictable but they gave it that unmistakable Factory look!!

Waaah ! My DT360  :'(

Fork damping kit, Mulholland shocks, mild port cleanup, Bassani pipe and up 2 on the mainjet, TY speedo on the back of the fork leg, junked the clocks and indicators...

The morning I ran it in the oil pipe screw to the carb manifold came out and it seized. Let it cool down, got it going again and within the hour had a head-on with a farmer in a Morris 1100 on a blind gravel corner.

While pulled down for rebuild, it got stolen...waaah... :'(

Hey Guy's,

I was just interested in what were your favourite mods were back in the day, mine were ......

Suzuki TM125L

Filtron airfilter.
Bassani exhaust or Terry Bryant modded (shortened) stocker.
Skunkworks rear suspension linkages.Koni finned, alloy bodied rear shocks.
Preston Petty front guard.
TS100 kickstart lever.
ATF fork oil.
ATF gearbox oil.
B9EN spark plug.
Castrol R30 two-stroke oil.




Were those skunk kits rising rate or falling rate? From what I've read they were supposed to be rising rate which would have been a pretty good mod back in the day (with the right shocks), but I reckon they were reducing rate given that the angle of the shocks increased as they are compressed.

After just studying a tech drawing of the linkage, I have come to the conclusion that it is still 'straight rate' as per the original set-up, but the leverage ratio was nearly 2:1 making the stock spring way too soft.
