Be gentle with me, I’m a metric man! .....

The mirrors on my 2002/03 350 Bullet stick out wayyy past my bar ends and when filtering, it can be a pain.

Now, I may go for shorter mirrors later, but initially, I may remove my mirrors.

When I removed one to look at fitting blanking plugs, I checked the Mirror thread on my thread gauge and got what I think was G 20 1/4.

Now this is alien to me and I’m trying to find a plug to fit. Can someone shed some light on this size. Even Googling, I’m struggling.

Thanks.

Use blind grommets?

I did think of that, but you’re meant to teach me, oh master

Google harder.....Mr H has some that may fit your bike. I have them on mine.

10 mm I believe

Hey, I'm all for an easy life.

I'm surprised they use an imperial thread there. Do you have magura levers?

Our hosts sell blanking plugs for Minda levers which an '02 bike ought to have.

It does occurr to me that maybe they are just that classic enfield staple of "badly cut metric".

If they are Minda levers, they will be threaded in opposite directions anyway so it's going to need a specialist part to blank at least one of them.

Thanks Haggis and Stinkwheel, didn’t think of checking the site for a blanking plug!

My controls look like the ones in the shot on the link you sent; left hand thread.

I have to say that I printed off imperial, Whitworth sizing years ago. There are soooo many options! And all the British Gas sizes too!

Ahhh metric.. M6, M8, M10, with the occasional fine or coarse thread; simples Serge.

I assume you're aware that the mirror stems on a Bullet are handed, i.e. one has a "normal" right hand thread, the other one is left hand. I discovered this when buying the anti-vibration mounts from our host's catalogue and presumably the blanking plugs also have one of each.

Just to add, a lot of... but not all... Left hand thread nuts have small nicks? notches? filed on their corners for easier identification.

Yamaha used to use a left hand thread on the left mirrors back in the 80s they may still do, think that was a 10mm thread
