O rings

[spiderpig]

Anyone know if the o rings for the body of the starter motor are suzuki weird sizes or available from normal suppliers? Same question for the o ring joining starter motor and alternator to the cases?

If they're anything like the ones for the Blandit 12 (the large ones for the motor body) then they are square section and expensive when bought from Suzuki. I would be very surprised if there is a generic alternative. It's not impossible but in my experience rarely does a generic o'ring fit 100 % correctly or perform as well as the OEM item This holds not only for big, old Suzukis but other Jap bikes too.

Think @fatblokeonbanditfound a alternative for the alternator.

This is what you need for the alternator

the suzuki ones are 2,3  x 87 OD, almost impossible to find, i use these from simply bearings, 4 quid for 2.

Yep that does confirm my previous post 

Starter motor O rings :

on the 29.9mm shaft motor : 24.5x3 

On the 39.9mm shaft motor : 34x3

the norm for O-ring measure being the ID x thickness

it is obviously possible for this kind of fitment to use round instead of square section rings, oil leakage if any cannot be major
