Evening All,
I have had a rough running GSA 2008 since I purchased it, an intermittent problem at high speed around 4000-5000 RPM. Assumed it was because of a fuelling/ air problem but others stated coils. I got rid of the K&N air filter and cleaned the sensor in the air box for a little improvement, I then had two coils and all plugs replaced by my local BMW dealer who stated one was shot and the other an incorrect fitment, the bike ran good for around a month then the issue returned.
I have now changed the main fuel pump (LHS) and the bike seems stronger (maybe imagination??) but the issue is still intermittently there. I am now thinking of changing the secondary pump on the RHS and the pressure regulator and looking at the breather hose before getting BMW to look at the bike again.
I could do with a little info on the pump for the RHS, is it the same model as for the left? And could the issue be with the pressure regulator and/ or breather hose....Where the f...ck is the breather hose?
Any opinions and advice would be greatly received.
Many thanks.
