could be a vacuum being created in the fuel tank, try opening the cap when it next cuts out and see if you can hear a whoosh noise. if it is that its an easy fix just needs the breather cleaned its normally part of the petrol cap itself.


The other thing it could be and id say is more likely is that your battery is low/f***ed, wack it on charge over night and see if that improves anything, if it does carry on check the battery with a volt meter it should be around 13v when the bike is turned off i cant remember the rest of the voltages when running etc but i'm sure someone who does know will be along although thinking about it it could be 12.6v..

fuel pump , buy brand new after checking for blocked drainage and breather hoses should be checked during service.


fuel pumps were recalled on 2010-11 models but my 2012 failed too. it cut out once last year then refused to start this year. tapping the pump with a screw driver unstuck the relay. they replaced under warranty due to end this month. so get it in ASAP unless it was new jan,feb in which case you might have a battle on your hands.

I bought it new from the dealer and tonight its cut out about 4 times in a row and it felt really sluggish with no power and to top it of there seems alot of play on the clutch lever before it engages gear and revs like mad as if its in netural when its in gear

That's what I meant, at the end of the day it's not the op's fault so why should they have to arrange alternative transport. The dealer is more than likely to agree unless they want a bad reputation..
