SV650 clutch slipping?

[Calumh96]

Hi guys,
So a few weeks ago my bike started acting a bit funny, once i go past the half way point on my throttle to full throttle my bike suddenly jumps to red line revs and the power doesnt seem to be hitting the back wheel atall. Also if i full throttle from low speed (possibly wheelies) there is a huge delay in the delivery of the power. I checked my oil first and it was below the low i topped it up last week and it seemed to fix the issue. Now the issue has come back and is coming on and off randomly sometimes it happens sometimes not.
Advice?

Have you tried adjusting the clutch according to the manual?

Adding the extra oil added more drag, so masked the issue briefly.

What type and grade of oil was in there?

Try re-setting cable adjusters and setting the worm drive screw for the clutch correctly as per manual.

It may be a new clutch is needed, but do the basics first.

It's unlikely to be clutch plates needed, suspicion falls on the push rod which moves the plates apart when you actuate the clutch.
If it gets even slightly sticky with oily crap it doesn't immediately let the plates contact firmly when you release the lever.

You do use proper bike oil don't you and not car oil??

To check the clutch, there is nothing simpler, than riding at about 30-40mph, using the top gear, and suddenly open the throttle. If the engine starts dying, shaking... the clutch is good. If the revs go up while the motorcycle is not accelerating accordingly, the clutch is not good. The engine should never overpower the clutch, if it does then something is wrong. The sooner the clutch slips, meaning lower gears, the more fecked it is.

Also, check the oil regularly, not just when something goes wrong. Normally it's the camshaft that suffers from the lack of lubrication first.

i dont think this is an issue with adjusting the clutch because the clutch is not in use when the issue happens this is mainly happening when i am cruising and decide to accelerate harder

Im assuming he meant not the clutch lever/cable. Honestly at this point you need to rule out cable/adjustment and see if its anything more serious. If you said adding oil fixed it somewhat, that would assume its been running with very low oil?

So as above, just in case it needs saying another time.

Your clutch is slipping. It'll sound like someone riding an automatic scooter.

This can be for a variety of reasons, the easiest of which to check and fix is that the mechanism that disengages the clutch (so the lever, cable and pushrod) is not fully returning to the resting position. Hacving the same effect as the lever being slightly pulled in all the time.

After that, you're looking at the clutch itself which means draining the oil, taking off the RHS engine cover and having a look at it. The two most common causes in there are either badly worn clutch plates (there will be a minimum thickness in the workshop manual) and a notched clutch basket, which will be obvious to look at.

There can be various other causes too.

With an SV you need to adjust the lifter mechanism first, with the cable slackened off. Then adjust the cable.
