right, mine got about 900 hrs and 4500 miles.
no handy, the cost of new ones means they'll have to last wee bit longer.
usually change ours at 2-2.5 yr old but dealer telling me couple o months ago that same bike would be about £10500 now so kinda put notion outa my head :eek:

You would like to think they would be reliable at the price of them wouldn’t be that keen on changing for another had a 350 and a 450 over the 14 years before them and hardly had to touch them except for servicing

We had one of the first 550 injected models that didn't run well. I wasn't present but some investigation found what appeared to be a dead pollen beetle in the fuel line after the filter.
 
Did you wash the tank before replacing the pump?

We had the original fail and replaced it with now one and that has been single issue with it. It is made in 2007.

Yamaha fuel pump issues are widespread. Both the 700 and 450

Some bikes run faultless and never have an issue... some have multiple issues.

Yamaha know fine there is an issue.

Another win for carburettors. I never thought I'd be saying that.

I wonder if the bikes with a high failure rate are the same bikes that have no fuel when you go to use them? You know, the ones that get driven until they stop, then flicked to reserve and keep getting driven some more until they get refilled. It's as if the owners don't know there's a fuel gauge right in front of them.

Car fuel pump failures are definitely more common in cars that are constantly running on "E". Some people say it's because the pump draws in the sh!t sloshing around at the bottom of the tank, others say the pumps overheat because they're not surrounded by fresh cold fuel.

Grizzly 700 costs 12500€ here, Kodiak 700 costs 11500€ and Polaris Sportsman 570 Hunter edition costs 11500€. Final price for Yamaha is the one that reads on the note and final price for Polaris is 9500€. Basically makes no sense to buy barebones Polaris and add winch to it, as you'll pay the same for the fully kitted Hunter Edition as you'd pay for the base Eps version with winch added. :unsure:

New bikes don't have reserves on them.
What you're saying/describing would apply to all bikes, whereas the issue is Yamaha only.

Shows how many new bikes I've owned and driven.

Out of curiosity, what brand of fuel pump do Yamaha fit to their bikes?
