JellyBelly12345 Posted December 13, 2011 Share Posted December 13, 2011 Hi guys,Just a quickie!Recently done my first ever major (well major for me anyway) service on the bike and rode it to work this morning and have noticed a delay between rolling on the throttle and the bike accelerating - no weird sounds from the engine or any weird vibrations just this slight delay of about a second.In the service I changed the air filter to a K&N, fitted new spark plugs and change oil/oil filter.I'm assuming i've cocked one of these up, but any ideas which one?Cheers!

megawatt Posted December 13, 2011 Share Posted December 13, 2011 Possibly the K&N mate. You may have altered the air/fuel mix. try the old filter back in? Quote Link to comment Share on other sites More sharing options...
giocast Posted December 13, 2011 Share Posted December 13, 2011 plus one - and don't go pushing hard 'til you change it back just to be on the safe side. K&N will often suggest what size jet you might need (if at all) when changing to their filters. You might even see a small rise in running temp in worst scenario.

Stu Posted December 13, 2011 Share Posted December 13, 2011 Is it the gsxr750 in your profile ? If so its fuel injected so forget up jetting as above it would need a power commander As suggested try the old filter back in also check to make sure the air box is sealed tight to and on the throttle bodies properly too Quote Link to comment Share on other sites More sharing options...
JellyBelly12345 Posted December 14, 2011 Author Share Posted December 14, 2011 Cheers guys, I'll switch it back at the weekend and hope it solves the problem. Quote Link to comment Share on other sites More sharing options...
giocast Posted December 14, 2011 Share Posted December 14, 2011 I shouldn't ask, but did you change plugs for same as before - i.e. correct ones? You could pull one out just to check how it's burning since filter change. Quote Link to comment Share on other sites More sharing options...
JellyBelly12345 Posted December 17, 2011 Author Share Posted December 17, 2011 Thanks for the help guys, fitted the original air filter back in and works like a dream.Now have a spare K&N lying around the garage if anyone needs one? Quote Link to comment Share on other sites More sharing options...
megawatt Posted December 17, 2011 Share Posted December 17, 2011 Does it need oil on it to work properly? Quote Link to comment Share on other sites More sharing options...
