having been researching the TICK on the net, i found the following on the R1 forum:

No problem, luv2ride, I run an R1 Y2K bought new, now 5000km. My R1 started ticking like yours after 2 days, so I got in touch with the tech dept. at the Italian importer Belgarda and this is what they said: The noise is common to about 15% of R1 production and is caused by the followers under the camshafts. These followers have a min/max. tollerance and if they're on the max side, the followers on the left side will click. This is due to a very slight drop in oil pressure on the left side of the valve train as the oil pump is situated on the engine's right hand side, thats why it doesnt click on the right! Now, these "noisy" engines are reputedley considered to be slightly more powerful than, all else being equal, non ticking engines (due to minor attrition), to the point that many racers fit followers on the max. tollerance side.
Belgarda proposed to change the followers under warranty if I wished, (each follower has a colour code, there are 3 colours according to dimension) or if I found the ticking to be disturbing but I eventually declined (after a while you get used to it and its nice to know youve got one of those 15%of more powerful R1s) . Cheers , Pete


has anyone heard this before and is it true?

I recently built my race bike with tolerances close to the max for the valve clearances and the engine makes a lot of noise on the left side. None on the right because the cam chain and sprockets are there so there is a gap and cam sprockets for noise damping i suppose.. but on the left, 1/2inch behind the casting there is 2 cams hammering away.

I would be worried if the noise started out of the blue.
Technically, the noise should slowly go away as the valve seats itself into the head after 20, 30k miles. :)

"Hey mate,

I had exactly the same issue on my 06'. Get it checked out ASAP - i initially thought it was just the yamaha tick aswell untill my engine screwed up.

Brought it to my mechanic and when he opened it up he said apparently the cam chain tensioner was making that noise and eventually gave in and the cam chain slipped off and bent one of the valves causing enormous damage.

In the end it was cheaper for me to get a replacement engine which still cost me 3k

I suggest you stop riding and get it sussed out

let us know how you go"


This is what i posted on another Ticking thread

Can you describe the "ticking"? Mine ticks as well even well after its warmed up, doesnt seem to be any different when its cold or warm though. Im at just over 9,000 miles and have records of all oil changed done at proper intervals so hopefully its nothing serious
