Colin the Bear Posted July 31, 2011 Share Posted July 31, 2011 The faster the engine revs , the more fuel it draws. You have enough getting through for 5k but no more. Could be a partialy blocked in line filter or kinked fuel line. Quote Link to comment Share on other sites More sharing options...

Could be a partialy blocked in line filter or kinked fuel line. I have the same issue with a CBR400. It won't go above 8k revs. The airbox is broken and doesn't quite connect on 2 carbs, would that cause it? Quote Link to comment Share on other sites More sharing options...

7vwh Posted July 31, 2011 Share Posted July 31, 2011 check there's nothing blocking the air intake, it's just forward of the battery. Quote Link to comment Share on other sites More sharing options...
Tango Posted August 1, 2011 Share Posted August 1, 2011 Clogged air filter......not the most likely cause...but easy to check.Is it only in top gear that this is happening.....or is it 5k plus in all gears? Quote Link to comment Share on other sites More sharing options...
megawatt Posted August 1, 2011 Share Posted August 1, 2011 Don,t think anything to do with fuel. Maybe a switch in the ignition circuit that is vibrating.? Wd all switches and test em? Quote Link to comment Share on other sites More sharing options...
rennie Posted August 1, 2011 Share Posted August 1, 2011 I will bet it's none of the above! It will be the exup valve not working correctly!it opens at around 6000 revs. Quote Link to comment Share on other sites More sharing options...
7vwh Posted August 1, 2011 Share Posted August 1, 2011 if the exup isn't working properly then the tacho bounces up to 7k and back to let you know. Quote Link to comment Share on other sites More sharing options...

Could have any manner of stuff in there!! Quote Link to comment Share on other sites More sharing options...
TC Posted August 1, 2011 Share Posted August 1, 2011 Have you put any Comms/sat nav equipment under the seat.There is a lovely little compartment under the seat to fit it all into. However the whole compartment has to be left empty to provide enough air flow for the intake. Quote Link to comment Share on other sites More sharing options...
fazerboy Posted August 1, 2011 Author Share Posted August 1, 2011 Well funny you should say that....i just disconnected the hardwire for a tomtom rider and removed some wires destined to be used on some heated grips...but ive attatched a cigarette lighter attatchment....would this have affected it?

7vwh Posted August 1, 2011 Share Posted August 1, 2011 The electrical side of things shouldn't have made any difference, where you put the cig ligher attachment might have. Here's a couple of pics of mine....The opening is the intake to the air filterhttp://i229.photobucket.com/albums/ee79/7vwh/stuff/CIMG3245.jpgFrom above it looks like a small storage space, anything stuffed down there will affect the intake.http://i229.photobucket.com/albums/ee79/7vwh/stuff/CIMG3246.jpg Quote Link to comment Share on other sites More sharing options...
