Help needed, my bike a GSA 07 was just serviced (18000 mile) at AJ and I felt it had more vibration after the service than before.
Then on Saturday I fitted a K&N air filter (the paper one I removed was dirty. Should this of been changed at service) then went for a blast to the lakes, the bike is now sounding Ruff and has an occasional back fire, even on tick over. Any serious replies gratefully received:augie.

I am going to take a guess here.......

...but when i changed the headers on my HP2E and it was running a bit rough, i was advised to disconnect the battery for 5 minutes to allow the computer to completly shut down. Re attach the battery, and without turning on the ignition, completly open the throttle and then close it. Now start the bike and take it for a ride. This SHOULD allow the bike to reset the computer to the new information it is taking in ie fuel / air mixture and you should have a smoother running bike!!


Hope this helps

Try the TPS reset .......... Turn on ignition and allow the bike to go through its self checks but do not start the engine. Once the checks are complete slowly twist the trottle to fully open then back to fully closed. Do this for three cycles then turn off the ignition. Turn the ignition back on and allow the bike to go through its self checks then start the engine :thumb2

Was gonna suggest the TPS reset, I run a K&N with no difference so it can't be that.:thumb

At the risk of sounding dull, why run a K&N filter? What does it give the bike in the real world?

Because if you used your bike in Western Australia like I did, you'd be changing the paper filter a lot more often due to the amount of sand blowing about everywhere (the place is one gigantic windy sandpit). Either that or you'd run the risk of the bike running hot due to very reduced air flow into the engine, and WA is pretty hot as it is.

A cleanable K&N made sense.

As for poor filtration standards, they are as good as the paper version provided they are cleaned and oiled.

There's little point in fitting a K&N for ordinary UK road use unless you are tuning with cams/fuelling/exhausts as it would take a few years of servicing to pay for itself compared with disposable filters.

Or it was FOC and had a 12k service coming up :aidan

My bike, my decision, based on experience with K&N filters
