Loss of power

Hi
I’m trying to figure out why my 350 loses power. It’s a 1996, just last week I replaced the (original) battery and also the rubber tube from the carb, which had split magnificently. Starts like a dream, ticks over and then when I put it in gear and set off it just dies. I take it over fields to go pigeon shooting and today it was about double the weight in mud, and it died on me when I got back on the tarmac and I had to push it most of the way home.

Done 6,500 Miles, it was a former “blood bike” running from medic station to helicopters with a Red Cross on the tank (I know this as an old RLC colleague of mine was the one that “demobbed” it), somit probably never got out of 2nd gear until I got it.

I’m sad and confused about this. Any help?

Thanks all. I’ve a new carb rubber so I can rule that out, I hope. I do have a tendency to screw the fuel cap really tightly, my other bike is a Fatboy and they leak if it’s not screwed massively tight, so I’ll check that first. I’m a fan of trying the simple things first.

Cheers for the advice. Happy and safe riding all.

Have you checked the carb diaphragm rubber, under the carb top plate, as suggested by Minter?
