83 upgrades

[thekid]

Can anyone list for me the differences between the 82 and 83 bikes? I've run out of things to fix on my Vision (for the time being anyway!) and would like to do a conversion on it. also , a parts list for the dual disc brake conversion would be great. and, I think I heard someone say that I could fit a 120 rear tire on her, is that as big as I can go? thanks all, the kid.

different on 83
fuel tank: sending unit, petcock.
carbs: different inside & out, different fuel pump, matches petcock.
Guages: fuel meter & speedometer
Risers: shorter
ft forks: air caps & progressive style springs
Fairing: upper, lowers with vents, windshield, oil filler extention, dashboard, extention wire harness. relocates turnsignals & headlight slightly. reflectors on rad shroud moved to fairing. 4 piece frame (including lowers, fairing mounted mirrors.
Ft brakes: different master cylinder, smaller diameter rotors (so tubes are different) plus duals of course.
Rear shock: added dampening (82 shock is a pogo stick by comparison)
rearset pegs, extended shifter linkage & brake pedal.
top of tail section smoothed out.
stock exhaust has narrower I.D. head pipes.
color scheme: black with gold accents (rims, pinstripe, etc)
engine: different crankshaft, lower compression rings, reportedly different cams, but not shown in parts fiche.

i think that's everything...

TIRES:
A 120 will "fit" but it is NOT CORRECT!
a 110 is the widest tire that can be properly mounted on the narrow vision rims.  When a 120 is mounted on the v's rim the contour of the tire changes, thus the contact patch shape is altered, and thus traction suffers.  Plus, the tire will be taller and narower in profile due to the sides being pushed in, thus less strait line traction.

go with 100/90/18 front 110/90/18 rear No exception!
Avon Super Venom's seem to be the favorite, though I will most likely go with pirelli sport demon's

Does anyone know if the Seca Turbo Rims are any larger?

if i remember right (memory's fading fast!) they are shorter & a little narrower & need shimming to fit, but the axel dia is the same.  if i remember right...
