R1 5VY, valve adjustmet
Anyone done it?
Is it a big task, can you do it in the car, does the head need to come off?
Got a ticking noise which is def rev related on one cylinder, (opposite end to timing chain)
It's only started recently second to last run at Harewood and is quite loud.
I'm hoping it might be the header gasket as the nuts had worked loose but I haven't had chance to check it out yet and I'm just
trying to think ahead.
There are loads of posts on the net about the yamaha "tick" but no definite conclusions on what it is or how you cure it. It might be
this? Plenty of posts saying just ignore it but the engines aren't under the same load or stress in the bike as they are in my car.
Hopefully it will be the gasket, if not I hope it is nothing to worry about as I won't have time to strip anything before my next sprint on
Sunday.

I thought about giving this a go with the limited knowledge of my engines past but i carried out a compression test first, wet and dry and was pretty
happy with the results to not to worry about anything else for the time being. I think valve adjustment is just rocker cover and timing chain cover on
the side. Sounds ok from the Haynes manual and id definitely pick one up if your looking to do it.

Cheers Bassett, I don't think there is a problem with compression, certainly no drop in power and it runs sweet as a nut its just the tick,
tick, tick.
