Reading suzuki engine numbers.

[_Iain_]

Trying to work out what year engine is actually in my bike now. Found road grime in the cracked front mount, so am assuming it's seen road use after being removed.

So far as i can work out;

M = 400-499cc
5 = 4 Stroke twin
01 = Engine phase. - However this is the same on both engines, although one is the low power silver version?

The rest of it is what im struggling to work out.

I.e M501 - XXXXXX (not posting engine numbers for obvious reasons..)

I've used the above site, but it's unclear as to engine identification.

M501 would mean its 400-499cc in a 4 stroke motor and the 01 designates that its first generation, ie ut cold well be from an 89.

from the website you listed
m = 400 -499cc
5 = 4 stroke twin
01 = first sequence

Both engines are M501, ones a silver low power engine with some sort of blanked off ports on the barrels, the other a black high power which matches my V5 (i.e 1992)

I belive the 01 doesnt count for shit in this case

Need to translate the other 6 numbers.

my silver engine didnt have blanked off port from what i remember, where are these ports, and before tweaking give 42 hp at the wheel.

also dont forget that those number may give you the place and time of munfacture but it maybe out of a different year machine. it no usual for for poeple like suzuki to keep stuff laying around - that why the original bandit 600 came into exsistance, they where trying to use parts they had lying around

also chech this out

https://www.suzukicycles.org/GS-series/GS500E.shtml

it appears that colour of the engine is no way to tell the power, here tehy quote an early rad machine with a silver engine as having 52 (which i doubt they ever produced no matter year or colour), a slightly later on with a silver engine with 47hp, the chances of noticing that smaller difference is unlikely.

with that in mind the later engines would most likely have m502 number of or 03 etc. the 01 give the design version, if the first design than you have the 52hp variation.

have you actaully riden it yet. if so does it feel as tho it has less grunt
