Just about to purchase an 89 100GS quite cheaply but it does have issues but againg this is quite cheap!(£1300). However the exhaust seems to be off a road bike RT maybe? as it has 2 exhausts and are low down, are these hard to get second hand for the GS? what type of cost is it. I would like a sports bike aftermarket one as they do look good on the GS.expensive to do- new bits or easy modification?

Also I have heard of people putting honda forks and wheels on the front for better breaking and suspension, anyone know which one fits or is at least the easiest to fit with fewest modification?.

I was thinking transalp or simular with front wheel yokes and breaks etc..

Ive not tried a GS before and it seems to whine slightly like a landrover does while moving along the road, is that normal? again I'm not used to bikes like this. It also knocks a little on tickover but soon as you rev it the knocking stops, it's not coming from the barrels more engine, many 2 strokes Ive had do this especially warming up and have always been fine, is this normal for a GS?.

All previous bikes have been Jap made, non twin or even air cooled so i could be just hearing what the engine noise makes as normal as they are noisier Ive been told but any tips would be appreciated. Mileage says 23K but i know it had a recon engine fitted in 1999 so that milage must be on he new engine.It drives well and I'm prepaired to spend a bit on it to get it the way I want it- perfect as I'd like to keep it for a while and travel to SAfrica next year.
