Got a little problem with the ZXR again.....it still sometimes (not all the time) is boggy below 5000RPM. It seems to sort itself out after a ride and on first start up.
I have changed the spark plugs and cleaned the carbs this afternoon. Any ideas what it could be? Its got low miles on it and has been well looked after but its just developed this issue. :smt013

Thats a shame, thought we'd got this sorted for ya!

How were the plugs that you took out? Colour etc...

They were all fine! Its strange how yesterday it was running fantastic but went out after cleaning the carbs was fine until i get back home then it was doing the same. Only seems to do it when it chooses. Thinking maybe the carbs needs balancing maybe or even the head gasket although if it was the head gasket it woudnt choose when it wanted to play up
