front fender and sidepannels yes.
just one thing, the side pannels ure superceeded to 14L colour. im not sure what colour this is. that is from
www.alpha-sports.comtry an australian suzuki dealer first as things could be differerent here and they may still have some of the 163 colour sidepanels in melbourne warehouse. also try Mick Hone Suzuki. they could have some side covers. and also ask suzi parts in adelaide. if he hasnt got any in stock ask him to do a 'worldwide search' for you which he does.
soem stuff alpha sports are saying are NLA or superceeded but recently i have found out to not alwayts go by this as when you try to order the same part in australia, you often discover that there are still stocks in Japan and the part is not superceeded.
what do you mean by polish the head and barrel? do you mean as in a port job or for external cosmetics?
if its internal polishing your looking at then yes you could smooth out the ports. i would get the bike going first and then see how it goes and decide on the type of power you want and then speak to a reputable 2 stroke tuner to discuss port jobs etc. if its cosmetic polishing your talking about, i personally wouldnt do it. i would rather bead blast and paint black for better head dissapation.
