Thanks everyone

I started the bike up last night and it didn't make that strange sound on startup (I'd say it's like a hollow metallic cough) and I ran the bike up to temperature. Then, at around 80 degrees c I turned the bike off and started again and then I get the cough sound, so I think like you say Woaty, things have expanded with the heat. I backed off the front tensioner a bit and this appears to have rectified that problem. I backed the rear off a little too.

I'm pretty confident now that it's all ok. There is still a background tick, but I still think I might be paying too much attention to this as it very faint, and as Cybercarl pointed out, manuals do sound different to the originals.

Cheers everyone,

Gav

I get the cough sound
When you say cough are you sure this is not just the carbs spitting back. I think you have got/had too issues going on here. The first is the manuals where a bit tight, and two, a bit of carb cough. If it is your carbs spitting back then don't worry about that for now that is a separate (tuning) issue. It's nothing to worry about and can be sorted at a later date. What is important, is that you have your CCTs done to the right tension. :thumbup:

Carl,

I think I might have confused things by describing it as a cough. It's a difficult sound to describe, but it seems to be cured by slackening the front CCT

Cheers,
