Fuel starvation or what?
« on: 22 September, 2019, 05:03:37 PM »

 Hi just returned from a short trip to Italy and Austria, my Biffer has spent its 12 year life on a small island and has only completed 20,000 Kms,  I bought in Feb of this year, only had 16k on the clock!

 Anyway, had the chance to open it up and keep the throttle at between 4500 and 6000 rpm, got the wife on the back with panniers and topbox plus twin tank bags, fully loaded. On more than a few occassions felt the need to pass  long lines of HGVs travelling between Venice and Innsbruck, only too find that the power was not there, starting to stutter and power dropping off with a BMW coming up behind with lights flashing, had this happen before, between Athens and Patras, I hit the kill switch, hit
 it again, opened it up, bingo we have ignition, flashed past the lorries and pulled back into the slow lane to let the racers go by! This must have happened at least a dozen times on the journey so  I would appreciate any comments to finding a solution as I really felt on more than a few times it was a life threatening situation.
 My local Honda dealer reckons the fuel pump is the culpruit and possibly the tank has some rust particles that cause a tempoary blockage by hitting the kill switch off and on it stops the pump and somehow clears the jam! Seems a bit too simplistic to me, wonder if anyone else has had a similar problem?

Wanted to give an update on this issue I suffered with the fueling on the bike. Apparently, due to the lack of use the fuel tank had some rust in it, it was turned into powder form and was as I thought affecting the fuel pump.

 Luckily, it was possible to clean out the pump and the micro filter, the cost of replacing the entire unit would have been ott, my local Honda dealership was able to get 98% of the crud out. I also got an epoxy resin coating  on the inside of the tank to prevent any more repeats. Have yet to test the bike on a really straight road yet but it seems to be running a whole lot better!
