[size=1em]The fuel pump behaviour has changed, clicks loudly for longer [/size] :rolleyes , filler open or closed it does the same. I switch the ignition on and the pump runs (great, if loud), if I turn off and back on several times it repeats the process for the same length of time roughly every time. My understanding of the operation is that it works on pressure and shouldn't lose it that quickly. When I first got the bike it would click a couple of times each time turned the ignition on (shorter when warm or had not long before primed) as I would expect, not sure why it's doing this now. It is quite loud, video: https://youtu.be/vI0JQTH54Bk. Bike runs fine but don't want to get stranded with a dead pump. Any ideas?
It's sounds to me as if your pump has had it's day and is indeed not holding pressure.
Quote:[size=1em] As far as engine is concerned, took it to a mechanic for a listen today, said it was likely the cam chain (https://youtu.be/l4SvuQYGRm4), Suggested loosening the two mounting bolts on the tensioner until clicks on the auto rachet, then wind the mounts back in. Not heard of this method before but would be easier than removing everything to get to it! Any thoughts on this? [/size]
Don't do this, you run a high risk of over tensioning and that will bugger the chain and the blades. Now I'm saying this chap is trying a fast one and he could be right but it's very common practice, they tell you it's your cam chain and it's not. They know it charge you for the work and all the do is take the cam cover off, reset the tensioner, reset the air mixture screws and balance the carbs. Job done and you're a good few £100 light.
How many miles as the bike done? Cam chains on Fazers are good for 70k easy I look after one with 85k still on original cam chain. Fazer's do make cam chain noises when the carbs and mixture screws are out and they can the tensioner can get stuck between teeth. Get the crabs balanced first (not be this chap) then take it out an and reset it as per the manual, or put it in second gear and turn the rear wheel backwards by hand.
If none of that works it's very likely it's the cam chain.
