Hello,
Possibly buying an sv1000 ,
It’s done 45000 miles , is reasonably tidy but has an engine knock on idle which disappears when the clutch is pulled in.
Any advice or comments would be greatly appreciated

It is very likely one of the following items if it goes away when clutch is pulled in

1. Typical clutch basket slack that gets worse with time. Can be often be repaired by sending basket out.

2. Primary gear is loose. You see this now and again on these bikes.

3. Many 03s (especially early VIN) have excessive crankshaft end thrust. They will almost sound like a rod knocking at idle sometimes. Thrust clearance can be pulled up to a tighter spec by a bit of machine work.

Clutch shouldn't really kill the crank thrust noise MS ?

Sounds like "Idle Hammer". Caused by the crank moving side to side against thrust surfaces. Only heard at idle. Having two connecting rods on one crank throw in a 90 degree V twin allows it to happen. As one side fires it tends to push the crank to one side. When the other side fires it tends to push the crank toward the other side.
Only happens at idle rpm. Any higher rpm and the firing events happen too fast for the crank to move much side to side.
Pulling in the clutch lever usually does dampen the noise some. While the clutch basket rpm does not change when you pull in the lever ( basket is locked to the crank via the primary gear ) the internal parts of the clutch hub and all the transmission parts that move do slow or stop. This changes the load on the crank and dampens the effect that causes the noise. As Michael says, there are ways to make the crank clearance perfect so it does not bang back and forth as much. BUT...that is a LOT of work for something that I have never seen a problem from. They don't fail any parts because of it. A lot of them do it. DL's do it. The 2014 and newer DL 1000's do it even worse as they have a different crankshaft.

Is it a K5?
Mine had terrible knocking at idle, sounded like a couple of skeletons copulating in a biscuit tin, which was caused by the clutch basket...5 out of the 6 springs in the back of the basket were broken.....aparently there was a bad batch of springs on the K5's which were prone to breaking.

Had springs replaced when i had the basket fixed for the 'chudder' fault by sharealike......his details are on here somewhere. As you are in UK, Sharealike is your man for clutch basket repairs

Hey,

Anybody can recommend a great garage for a clutch basket service for my K7 SV1000?
By service, do you mean to remove the "chudder" ? If so, the best fix is to speak to realshelby , his reply above, and get on e of his WERKS rebuilt baskets.....they are the ducks guts.
USed to be a guy in the UK that did similar, but nobody has heard from him in 12 months......
