Opinions Please

I have no idea if this will work but here goes

first engine knock - any ideas what the problem is ( should I worry ) ?

second engine sprocket slack this is in gear and just rocking the rear wheel back and forth.
seems like an awful lot of movement to me, it makes riding in slow traffic somewhat snatchy.

triumph Bonneville 865 se 2010

I will confess to not a lot of use, the oil and filters were changed last year along with a new timing chain spring which I thought would stop the knocking but apparently not. probably only done a hundred miles since.
mileage is just over 12k.

any help would be most apricated

 

Hi thanks for your prompt reply.
Your videos of the drive movement are reassuring.

The knocking is shortly after the beginning there's around half a dozen knocks and then it stops and sounds ok for the rest of the time. Sometimes it's a lot louder and lasts longer, I was wondering if maybe a valve was slightly sticking or something

 

Thanks have done that today, tension was fine

 

hi sorry for the late reply, my brother passed away and had the funeral so not been back here since. I did my own oil and filters change, I used Motul 5000 4t 10W-40. I have to say I have used the bike a for a few runs since and it has greatly improved, so maybe just a little dry after standing all winter. I haven't checked the valve clearances yet although it is on my to do list.
thanks for the replies.

 

I've purchased the valve cover gasket and seals for the screws, unfortunately we have the great grandkids this weekend so I've no spare time to check the valve clearances, so hope the weather holds into next week.

 

Right have taken the valve clearance readings all 4 exhaust valves 34 inlet from the left 26 - 24 - 20 - 20so cams are out along with the shims. Unfortunately my digital vernier calipers are playing up, not giving consistent readings so have purchased a metric micrometer from ebay a second hand Moore & Wright, so when it arrives I can work out what new shims I'll need.

Just odd bits left I can't read any of them but the micrometer has been posted already so should only be a few days before its here. Then it's going to be how long it takes to get replacement shims. Hopefully maybe able to jiggle a few of them around if I'm lucky, as no doubt they will be a few quid.

 

the micrometre arrived and shims have been measured, now providing my maths is ok the shims I've ordered should be here by Wednesday. I ordered from my local triumph dealer as no postage. all I need then is for the weather to behave so I can re-assemble.
