hi guys
Hope somebody can help my heads done in
ok
09 r1 17000 miles
2 bros cans
after market y pieice
K&N air filter
Flash tune
Having problems in low revs the bike seems to be wanting (best way I can explain is like riding a 2 stroke that's running out of petrol) bike hesitates a few times then picks up you can be doing 70mph in top gear at 5k revs roll the throttle off then gently back on and the bike stutters.this also happens in lower gears but same principal Strange thing is that for about 60 miles after heading off the bike feels brilliant then gradually the wanting starts
Have replaced the fuel line which had a small kink in it have even put the old plugs back in case in it was a dodgy spark plug checked all connections I have no error codes
forgot to mention
This also happened to the bike early last year before flash tune and lasted about 4 weeks but cleared itself
I have took it to Yamaha today and typically when mechanic took the bike out it never happened so he said difficult to diagnose with no error codes and not happening on test ride but they said will put it on dyno to see if fueliing is ok
worrying thing is he had never heard of flash tuning(must have been living under a rock lol
really need some ideas for when I go back to Yamaha on Friday so they don't bullshit me
cheers guys
Brian
