SHOWDOWN BACK SLOWER THEN EVER! Member 706 Member For: 17y 5m 10d Gender: Male Location: Sydney Posted 01/10/07 11:02 PM Share Posted 01/10/07 11:02 PM Mine has none of this.... If I get it up on a dyno will, they be able to tell me if im getting valve bounce/float?The dyno is the surefire way of noticing this problem. It is the safest method.I noticed mine on the street with generics in, cold nights or first thing in the morning. If I gave it a bashing it would cough and weez for about 60secOzzie Link to comment Share on other sites More sharing options...

In the wet... no problems. Is this valve springs or plug gaps closing up?No sigh of valve spring issues on the dyno with 267rwkw's but clutch was slipping. Detuned to 250 exactly due to clutch.
