No fuel pump buzz, won't start (600+ miles)

Degreasing and replacing the relays is only part of the problem because you need to check the female part of the socket and make sure the connections are pushed up in the socket to ensure the pins on the relay make a good connection otherwise this is the reason for intermittent starting problems and the fuel pump not primming. This happens each time you push relay into the socket so it’s best to check the female side of the socket each time you remove the relays.

Yes, I've pulled the whole cluster out and removed the rubber holder so I can get my hands around it all. I've made sure all are properly seated. So now only time will tell how successful the new relay will be.

Handlebar switches dint last forever either - DAHIK .
Not weatherproof and can corrode out PDQ
Nil stock in Oz , back order , no DD .
H have them at Indian prices but charged $A60 - for DHL Express , more than switch was but total still less than Oz price, if the had any!!
Had to fire up the R80 G/S PD, warmed up 1000 motor probably makes 40 hp more than the Hima but surprisingly how little difference in normal riding.
Makes me wonder what the guys who claim a extra 2 1/2 hp from a cam swap transforms the Hima are smoking!

Thanks for the warning Roy. I'll take the switch clusters apart and see if I can smear a bit of grease in there. Fortunately I don't ride in the rain these days although 2 foot deep puddles can be common 😁

My old R1150 GS only puts out 20hp more than your R80 - or it did when new - but I do agree with you to a point about the feel not being hugely different on sweeping 40-60 mph roads. Although it is nice to know there is a lump of power spare for when I need to make a quick overtake.

Just my experience with the fuel pump relay not working properly.
Installed Toyota Nippondenso relays to replace the stock relays.
The bike would still stall.
Cut off the stock connector and crimped on new female relay terminals.
Issue gone.
The stock female relay terminals were too loose. Ideally, it should be very difficult to pull the relay out of the connector.
The stock connector can't even hold the relay in place.

That is not an issue on my 2021 bike. Those relays are damned near impossible to remove. However, you make a good point that could help some people.

I agree with both of you. I bought some new relays as back up. But realised that the pins (legs) are much thinner than those on the originals that came with the bike.
So the originals are really tight, but maybe if I put in the new ones they may be loose.
Having said that the vibration of the bike has made my original come up slightly once. 🤔
Hmm 🤔

My 21 is exactly the same, pulling those relays was an absolute pig of a job, extremely tight but i replaced anyway, prevention better than cure right.

I've not replaced them all but I have two spare Hella branded relay's stored on the bike just in case. The odds are three won't go pop at the same time 🤞
