When used in anger the bottle screws itself up as it pulls a vacuum inside, also WD40 leaks out while in use and so almost as much goes on your hands as the target.
I tried using a different spray bottle - bathroom cleaner type one, that worked fine for a few squirts but then coated me worst than the WD40 one..
Has anyone else found this and/or found a pump spray type that works reliably with WD40?

Totally agree Rich. I sent two back and got replacements from WD40.
They were just as bad so I buy cheapy ones from Kennies to use instead.
Something I saw recently was a rechargeable arerosol. Fill it with fluid and use a Schrader valve to pressurise it. Must ask Olly Cooke where he got it - or did he make it
WD leaves a lovely greasy coating that makes the engine, frame & plastic look good. From what I hear Pro-care dries out after few days.
I also use WD40 for under the tank area, to give the electrics extra wet protection.
Mainly I use it as part of a quick clean process for the chain following the jet wash, that is if the chain isn't going to be taken off for a thorough clean, then I oil it properly before use.
All these uses from one product, not to mention it is also a penetrating fluid etc..
The only ones I have had any success with in the garage trade are the pump up ones like the hoselock one above. However I would buy one meant for brake cleaner as the seals withstand the solvents used.
I think I bought one from autoquip for about £17 but that was years ago, such has been the quality of it. Its withstands brake cleaner which is quite aggressive, also engine cleaner and WD40.

That's why it's called WD40 - 40 uses
If you can remember back to the early 70's It was actually called Rocket WD 40 the originial cans were orange and had a mil spec number on the side WD War Department . The original civillian retailers were general motors and you got it from your local vauxhall dealer. it was late 70's before someone bought the rights and made it well known. before that all we had was PLus Gas, 3 in 1 or Parafin
As for the bottles that come with it, they are shyte always have been, what do expect with something that is given away,local garden centre spray bottles at about 50p are best

Riding with enthusiasm upon the ragged precipice of disaster
I finally figured out why all the cheaper pump sprays fail after a very short time (no excuse for WD40's one though - they should know better).
The cheaper ones use some sort of grease to make the seal between the rubber plunger (of the pump piston) & the plastic wall (the chamber) water tight. It's nothing to do with WD40 being aggressive, it's because it is a solvent to grease. Once that's gone the spray will start leaking WD on each trigger pull.
So it seems the only answer is to buy one of those pump things that can withstand brake cleaner, or one of those refillable aerosols as neither of them will be reliant of grease to make up for the poor fit..
Just about to change my chain sprocket set this weekend. It has been recommended to me to only use WD40 on the O ring chain.
I usuaully use a chain lube, but the stuff is so sticky that it always gets caked in sand and mud and then eats your chain. The guy at the shop said forget chain lube just a bit of WD40 on it after washing to stop rust and let the O rings do the rest.
What do you think, sounds logical?

From what Rich says it would be as well not to go overboard with the WD40 on the chain as it may wash out the grease on the O rings
After power washing, I try to take the TTR out for a run to dry off the exhaust and chain. I go to the petrol station and top up ready for the next run so there is a purpose to the ride. When I get back the chain is usually dry and warm and ready for oiling with Wacky's low-fling chainsaw bar oil
