Tony Doms My 2008 emits this clunk at start-up from a cold start and only once at each cold start. This has been ongoing for 3 years and the problem has not escalated so I have done nothing about it, now that you have clearly identified the problem I will get by spanner man onto it next time the bike goes in for a service. Huge thanks for sharing your experience with us on this issue.

Hi ScotchBloke,

As Rayzerman said - see post #51. Bike is running perfectly since this work was done. I have done a 1500 km ride since and can say that it is running perfectly still and is sublime to ride.

Let me know if you have any other questions and best of luck.

Regards,
Dave

Have tested TPS - fine
Have inspected plugs - fine

Does not sound like CCT, have listened to various videos.

Help......

HFJeff Happy to hear this is fixed and that it did not require a complete teardown. Thanks for keeping us all posted.

ichsnoo Absolutely understand the mechanics perspective. He must deal with some interesting situations from some unusual bike owners. It is my plan to stay on his happy side. I am sure I will need his services again and he absolutely knows his stuff.

Just a bit of a bear in attitude, fortunately he was tempered with me. Out of the 3 times I spoke with him the first was probably the frostiest. I bought the bike to him without the fairings and side panels and a bunch of issues. He was probably thinking oh my what am I in for?

I think a six pack of red India pale ale will help. Due to drop some down next week.

Regards,
Dave

passx I think most really competent mechanics have that attitude, some because they tend to be older (experience) and we all tend to get more short and direct the older we get and probably the real reason is that they view home mechanics as hacks and amateurs that take money out of their pocket plus they get stuck trying to figure out what has been done.

I worked at my friends bike shop for a while (probably the most competent gl1000 guy I know, but very grumpy at times) and some of the things that were done to bikes before the owner brought it in to get fixed surprised me. Plus some of the attitudes of the owners when they brought a $500 bike in with the instructions of “just fix it” even though you try to explain it may cost $1500, they figure just because it”s old that you can fix it for $50.

I have a 78 gl1000 that is exactly that case, the guy just wanted it fixed so he could ride it, when he was presented with the $800 bill he just flipped out even though it ran great he just handed over the title. Rebuilding the carbs alone was $600.

Either way, keep in contact with your mechanic and if the bike runs as well as it sounds let him know, everyone appreciates a pat on the back.

That attitude seems to predominate among competent motorcycle mechanics. It's annoying to deal with, but is so much better than dealing with a likable incompetent mechanic. LOL

I think its just an air valve operated by a wax capsule heated by the coolant that lets air in between the throttle butterfly and the inlet port, it increases the idle speed, so not a choke plunger, really should be called a fast idle valve, the ECU takes care of enrichment according to the temperature of the coolant.

I would still really like to know what was causing the mechanical clunk.
