I would get you to help me, but I'm poor. I don't even have enough money to fill up the petrol tank. I do however have shitloads of vodka.

New battery for winter is the best start, maybe get your carbs balanced and tuned again and new sparkies at the same time.

Hope it pans out good for ya!

Can't afford any of that!

Push it down a big hill.

Have you tried push starting it?

Yup, it won't start.

Hmmmmm did you make sure you charged your new battery overnight before putting it in the bike...? When my old battery died, it wouldn't start at all even with push starting. I was told that the new battery I bought HAD to be charged for at least 8 hours to ensure it reached full capacity before I installed it...

Put new sparkplugs in it

That's going to be too much of a mission.

Sounds like it, I'll have to find that workshop manual I downloaded and I'll strip it apart and have a look. I might as well replace the fuel filter and air filter while I've got it all apart.

I cant believe its not already suggested , but here goes anyway.
Does it have spark ? ,
Is it poss you left a wire of when re-connecting the new battery ? ,

A bike that wont start after fitting a new part is normally associated to that work , i know you stated it was hard to start before the new battery but it did at least start so if anything it should do exactly the same now it has a new battery fitted.

It only has one positive lead and one negative lead for the battery.

I still think it's your carbs...

Hmm, another one to check is the fuel pump, they have a habit of dying, though I doubt this is your problem if you can smell fuel.

To check this, just pull the fuel hose out after the pump and turn the bike over, you should see fuel being pumped out of the line.

I can smell fuel when trying to start it, and I have already had the fuel pump replaced with one for an old Mini. I bought the pump new.
