hole

Doesn't sound right. Any chance of a picture

There should be NO hole there. The TTR250 does not have a coast enrichener and there is no need for a hole there.

Are you sure the hole is in part 1 on the fiche above or is it in part 14?

If it's in part 1 then it may be that someone had a vacuum line there such as for a Scottoiler. They then removed the accessory and didn't blank the hole

Thanks again Brian for your help, The hole is in part 14, on mine it looks as though someone has cut off the upstanding flange and thrown away item 21, what should I do,?

Oh no, somebody cut off your YEIS. The carb manifold joint is part N1. above.

I would suggest to find another airbox or at least cover the hole with some RTV silicone.

Thanks for the info Jarrah, what I have done is cut a short length of plastic central heating pipe with a stop end on it and pushed it in the hole, its a good tight fit so should be waterproof, now the serch begins for the replacement parts,

No problems, glad to help.

Hope you find the parts cheap.
