Fuel Tank Filler Cap

I want one of these for my bonnie, out of stock now[/QUOTE]

 

Try a bit of penetrating oil on the seal allowing it to soak in. It wont damage the seal or the paintwork and might just free things up so you can remove the whole lot. Then deal with the lock when it's free from the tank and you can see what's stopping it from working.

 

lol. Barn find? If the rest of the bike is in similar condition you’ve got a big project ahead of you.

 

Before you bin the tank, or try expensive cleaning treatments try ordinary cheap vinegar.
Almost fill the tank with vinegar, add a few large nuts shake the tank and then leave it for a few hours, shaking to rattle the nuts about, drain out the tank, separate the sediment and then put the vinegar back and repeat for several times. It might take several days but you will be surprised at the difference.
When finished with the vinegar neutralise the tank with a solution of bicarbonate of soda.

I did this on an old moped tank and the inside of the tank ended up looking like new - Best of luck!!!

Go for the K&N’s








if you want to spend a lot of time and money buying jets, air screws and the like to get it to run half decent.
That was my experience with them anyway, oh and don’t park it in the rain and expect it to run right if water gets on them.
Kind of a long winded way of saying stick with the original air filter arrangement.

 

Wow, that really is bad

 

Wow seconded.
Replace the air box and get everything running, if you want upgrade later then fine.
At least, that way you know whats to blame if you have problems.

 

It's certainly non vented now!!!
