Hello guys i seem to have encountered a problem with a bike i purchased not too long ago that was purchased as a 1 owner from new.
The owner kept it clean and serviced by means of his local dealer and used the bike for touring all over abroad. He seemed a sensible chap who kept the bike more in the upright position as the tyres told the tail -squared off. Will be replacing these very soon.
Any how the problem i am having is when i first got the bike i took it for a good blast and probably took it past its usual strolling speed, I noticed when i got back from that days ride that knocking was apparent when sat there idling on start. I assumed it could be the exhaust HTEC valve so left it at that. The more i rode it the more apparent it was i was getting popping on deceleration like misfiring. A few days later i also noticed that it feels under powered even though it does redline through the gears. It refuses to go past 150mph like it hits a wall - private strip road of course
I am in the process of waiting for some bits to come so i can give the bike a compression test, I did buy 1 the other day but it does not have the straight piece i needed but rather the coat hanger type which refused to tighten up without twisting the line. I have also purchased a leak down test kit also.
I did notice when investigating that cylinder 4 coil was loose and would not click into place like the other 3 did. I have ordered a new coil which should be here today or tomorrow. i have also taken pics of the plugs which are the iridium range so see what you guys think. I sure do feel i am loosing compression in 3 and 4 that's for sure.
Also 1 last thing that i need to know, When i turn the bike over it hesitates for a split second or 2 like it builds up pressure rather than a quick instant fire up. This is why i feel the compression is poor.
A lot of thoughts and questions i know. Thanks for taking the time in reading this guys,
Ill look forward to your thoughts and advice.
