Expensive work needed!
 
My bike passed its MOT with flying colours on Saturday but the mechanic told me that the noise I had noticed shouldn't be there and that he thought it was the scissor gears???? (don't ask me!) and that to fix it he would need the bike for 2 days and because the whole engine needs to be lifted out that it will costs about £300. (not chuffed)

Has anyone had this problem or does anyone know anything about this?

(Apparantley it only happens on the older sv's as newer components have been updated.)

How many miles has your bike done?

Nickster78 07-02-05 03:32 PM

Bikes done 20,000, however it had a reconditoned engine put in it just before I bought it as the last owner had run it dry of oil and that has now still only done 5,000!

You want to get a professional second opinion... What sort of noise is it?

Also, it could be I'm just dense, but WTF is a scissor gear?

I don't think there are any of the type gears sometimes referred to as "scissor gears" on an SV.

Nickster78 08-02-05 10:27 AM

Apparently the scissor gears are on the camshafts.

Is this a 650 or a 1000?

If it is, as I think it is, a 650 there aren't any of the quietening 'scissor gears' on the cams, they're only fitted to the 1000s.

Far more likely is that the camchain tensioners are a little sticky, to make them work again usually doesn't require their replacement, in fact it usually doesn't even require their removal, just the cap removed and the plunger reset.

Please check this very carefully before going any further.

Of course if you do have a 1000, it is a possibility, however the problem was mostly confined to the early TLs, I've not heard of a problem with the SV1000 cam sprockets as they are of a quite different design.
