Issue 1 - Rattley "diesel" sort of noise at start up and when cold.
Proposed Solution - Replace the clutch side timing chain tensioner with the new model , and ensure proper adjustment of valves and rocker end play.
Issue 2 - Ticking sound (throttle side). I put the blade of a screw driver up against the throttle body (TB) and held it to my ear and it has a pronounced clatter that is absent from the opposite side TB.
Proposed Solution - Rebuild the TB (both shaft and bushing) using the kit from Bing.
Alas I have no real idea about these last 2
Issue 3 - A high pitched electrical whine. It sounds a bit like the whine you hear when the turn the ignition on but before you hit the starter. It used to be intermittent but it is now becoming pretty regular. My son who is ten can hear it from across the yard and proclaims that it comes from "inside the fuel tank" He put his ear on the tank to listen.
Issue 4 - Appalling fuel economy
I ride very conservatively but the bike is returning about 6.3l/100km This is not city driving but over a 70/30 city country mix.
I have done some things which will adversely effect the economy but I wouldn't have thought to this degree and really I'm not sure if they are the culprits.e.g.
- Replaced the cat with a Remus Y-Pipe
Neptune Muffler
Techlusion - only a tiny bit of fuel being added at idle
Any suggestions are much appreciated.
