Alternator oil seal

[Wellsy]

Am replacing the alternator oil seal as it  is weeping oil.
On the Simply Bearing websites they offer several at different specs and prices.
R21 ,R23, garter spring ,single or double lipped.
Which one do you guys recommend?

i'd go for the leak-proof seal. 

i'm guessing it's a 180 triple series 1 your asking about?
& i recommend Piet's earlier advice and use a thinner seal,  5 mm thick.
standard is 35 x 47 x7 mm,  but the 5 mm sits in just nice, with a bit more clearance to the spinning 36 mm hex.
i've been using the common garden variety local bearing shop seal.  haven't tested the last seal i just replaced the other week.
no,,  don't ask me how many seals i've replaced.  i found the alloy cover had a hair-line fucking crack!  :
cheers,  Mark

Thanks Mark for your advice. The bike is a 10003cl
Before putting all alternator and starter covers back on ,  I noticed a small shim on end of starter cog shaft which is supported by the cover. I put a straight edge across the shim to the crankcase either side. It was not flush , it was proud. This surely is not correct. Is there a specific clearance?

There should/must be a shim either side of the intermediate starter gear.  The shims prevent the alloy of the cases being eaten by the gear, does little in regard to spacing.  The gear has quite liberal axial clearance, ie, is rather sloppy, you can check before you re-fit the starter motor, just stick a finger in the hole... :
