Might be getting somewhere with this now at last.
Popped round my mates house for a second opinion, and with a tiny bit of load on the throttle to stop the chain jumping about we both had a listen with the bike on the centre stand.
I noticed that there were a few drips of coolant coming out from the water pump area.
So now as well as a dodgy O ring i’m wondering if there’s an issue with the impeller, which could well be the cause of the noise i’m hearing?
I had one go on me before on my old bike, although i don’t know if they are metal fins or plastic on these bikes?
That could explain the noise from around the front sprocket area as well as it’s right next to it.
Plus the fan came on yesterday, and today as well, when trying to listen for the noise so that’s another sign something’s wrong. Bloody thing made me jump, i can’t remember the last time i heard how loud it was.
I took tomorrow off to do an oil change and carb balance as i’m working this weekend, but now i can’t do that as the bike will overheat.
I’ve ordered another pump and seal though.
But not to worry, my day won’t be wasted as i now have a leak somwhere in my new rear tyre as well
It’s not a puncture, it’s either the valve again or the rims leaking, but i put 40psi in this morning and it was 30psi this evening, so it has to be sorted asap.
