Not sure but it might be worth draining it anyway.

If the the outer air screws be removed in situ that is great as I'll unscrew one to compare without having to dismantle the bike.

I didn't have any correspondence with the seller directly in China, I just ordered the screws though AliExpress here:

The description reckons they fit CBR + CB-1, but it could be wrong. I found a few other kits however on ebay (aftermarket from China) and compared the measurements which all matched, so I took a risk and bought some.

I've no idea about the 2 screws that are a different size though, mine might be the same but it was a few years ago I had mine apart so can't remember.

Silly question but do you know if I'd need to drain the fuel from the carb before removing the air screw?

JamesM check out my post in the much neglected Good, Bad etc section. It's the one on 90 that will be of most interest, but the Morgan carb balancer might come in handy too.

I haven't used either of tools, but the industry swears by them both. I look upon such items as one time buys that save many hours worth of dead money in mechanic fees, so they're on my Christmas list.
