Yesterday I went out on the HImalayan for the first time since the lockdown, on a permitted journey to go to the Pharmacy in a nearby town (about 5 miles away) to collect a prescription. It was a very hot day by our (West Wales) standards. I parked the bike and as I was setting off to walk to the chemists's, I heard the Himalayan make a strange groaning sound in addition to the usual clicks and pings as the exhaust cooled down. When I returned about 10 minutes later, it did it again. When I got home, and put the Himalayan back to bed in his outbuilding, I waited to see if it would do it again and if so, try to work out where the sound was coming from. It did, but I couldn't precisely, all I could say is that it's sort of from the engine area. I wondered if it was the petrol tank becoming pressurised in the heat so I opened the cap, and a lot of pressure was released, but a few minutes after shutting the cap again, the bike let out another groan! It sounds like air/vapour going through a pressure valve that is sort of buzzing quickly open and shut. Each groan lasts between 1 and 2 seconds. Everything else is normal apart from the groaning. I must say it was very good to go out for a ride on it, especially with the town and roads so weirdly empty. It's like the beginning of "28 Days Later", only without the zombies.
