500 Two-Stroke Tech

well slowly putting my early 53g (aussie red / white) bike back together, getting onto my bikes fairings, plastics had my first go at plastic welding eg side panels (black abs) and fairing (black abs) all welded and repaired then moved onto the front mudguard (all original 5/1984 parts) and its made...

Zing our bikes must of been on the production line together
I have 53G-000260 in NZ for 25 odd years and a motor 53G 000234 and another under 53g <500 frame (aus) all 5/84 L model or Mk 1 all prob from the same production run maybe ?

now that would explain all the early Aussie / NZ bikes mine included I think you will find they are all the 5/84 53g < 500 were released as RZ 500" L " models . the "N" models came later 1985 or Mk 2's as some people call them and then "RN" models (jap rzv) were made at...

jackson nice article Interesting dates, I wonder how many pre 5/84 aussie rz's are out there? also makes you wonder when the first ones arrived in Aus, and also are they accounted for in the production numbers?

side topic the numbers etched by hand to the cases eg on the 51x motor the 57 / ? behind the cables any idea what they relate to. Every time I have seen them no two engines seem to have the same numbers. eg are there good numbers to be had?

are you sure on this as my bike in 1984 came with 220 main jets then upon reading the 500L model manual (early 1985) found the manual said #195 jets so we order a set which yamaha sent along with a Jap 51x model manual . the jap model had #165 jets so we ordered a set as well. My bike ran very well ...

is that 2 copies eg page 1 rz500L last page rz500N or one generic? but thanks for the great post very quick helpful info

side topic again hopefully I can post a link to my pic re 3xv reeds and what I asume fits on it eg plastic container (I'm not a mechanic just puting the pieces in places they seem to fit) but was wondering 1st how they work? do they just add volume or do they maybe have a effect on airflow?eg pressu...

side topic not long ago a 3xv 250 motor and running gear arrived with some other RZ parts I brought and have since roughly put the bits together but the reed blocks have holes on them that plastic tank/bottles plug into them (I think as theres no where else for them to go) like expansion or overflow...

for jackson40 http://www.castrol6hour.com.au/1984.html was 1984 and was won by a kiwi /aussie combo R Scott / M Dowson and the weather at the NZ 6 hour (very strong winds and tight track) let the gpz900 out grunt it........ was a very sad day :sad: humble pie for years to come(mate had the GPZ) I wi...

I thinks Wikipedia has it wrong but even sept / oct 1984 there were at least a dozen teams eg 7 RZ500 starters in Aussie 6 hour and about the same number of NZ teams with RZ's some quite well sorted eg good enough to win the 6 hour so some of them must have RZ's that arrived quite early in 1984. How...

hmmm thats a low number lower than my manual says they start at, 53g 000101 :smile: Is it a 5/84 (aust) plate on her? just wondering if it was not one of the early 6 hour race bikes?, I can remember them racing on the track before I got mine eg aussie and NZ 6 hour and proddy races and that year,( w...

just a little info on production numbers page 1 of my manual (rz500L 1984 ist edition) says " the engine serial number is stamped into the elevated part of the left rear section of the engine. Note: the first three digits are the model identifications;the remaing digits are the production numbe...

not sure if this will work but one 4 sale here wish I'd kept her now but would like to say thanks for the rz photo line up especially the 4 dif colored front wheels (food for thought) 4 me http://www.trademe.co.nz/Trade-Me-Motor ... 674697.htm

hmm if I remember right mine was a rd 400G but my mate had One as well for proddy racing he said his was a 1980/81 Rd400H his was identical but 1or 2 years newer than mine but I don't remember any emmission equip. (was the first yamaha 2 stroke I had ,was a suzuki fan tm's /rm's etc and a swag of t/...
