Which tool to remove pilot (idle) jet?

[melville]

Bike is my 1975 R75/6 with the usual 32mm Bings. It's running (and starting) like one of the pilots is blocked. I'd fix it right now, but the bike is being stored remotely (long story) and I need to know which tool to carry the next time I get to visit it (and hopefully go for a ride).

Small flat blade screwdriver?

Wee hex socket? What size?

Allen wrench? Again, what size?

Idle jet is #5 in this pictures:

Needs a small flat blade screwdriver. The possibility exists that the o-ring (#6) will be damaged when the jet is removed. Don't know size. If it survives the removal, you should put a small amount of silicone grease on it so it doesn't rip up when reinstalling.

The O ring often gets chewed up when I remove the pilot jets even though they haven't been in long. I do it at least once very winter to clean out water condensate from the breather. I go through so many of them I'm using standard NBR O rings which may be marginal in terms of resistance to modern fuel - but they are very cheap in quantity.

I have the size down as 3 x 1.75mm.

Thanks! I'll hopefully report back on Wednesday.

Thanks especially for the o-ring size, Barry.
