Dealer bullshi* or normal? - SV650 SK6 URGENT

[hazza]

Hi,

I brought an SV650 SK6 a few days before the snow came. I only managed to ride it a few times before the snow and now I've ridden three times since it went. On Sunday I took it for a long ride and I noticed that when it was warm If I tried to change from say 3rd to first (i.e if traffic ahead is stationary so clutch in and shift down to first without releasing the clutch) the bike would only go into second gear. The mechanism still moved and felt as normal but it was as if the gear just wasn't there. To go any lower I had to release the clutch slightly at which point the bike would 'click' into a lower gear. I just called the dealer to explain my issue as it has happened 20 minutes ago on my ride home and was told its perfectly normal and is 'the nature of a v twin engine'. He said its very common on big bikes and assumed it was my first big bike, which it isn't. OK I've only OWNED one other proper big bike but Ive been insured to ride other bikes since Ive passed my test in which time Ive been on quite a few.

I'm not entirely happy with this diagnosis as it's not something Ive ever come across on another bike. My bandit didn't do it, my eliminator didn't do it, my dads intruder 800 (vtwin) didn't do it, none of my motorcross bikes did it, my step brothers intruder (v twin) didnt do it and none of my smaller bikes have done this.

Is it normal? Is it me being stupid? Otherwise the gearbox is typical Suzuki smooth.

I could sort of understand if it was happening when cold and iw ould think it was sticking plates or something but why hot?

Please help!

The guy said to bring it down tomorrow if I wanted to let the mechanic look at it, but by this time they will be able to get their stories straight....

Just to make it clear I don't downshifT multiple gears at speed, but tend to when crawling into traffic in the city!

No facts, but that really doesn't normal to me.

However, I sometimes had to slightly release the clutch to find neutral on my CBR125.

Nature of a V twin.

Course it it My SV was fine with it. It has an issue.

Think I may have found the possible cause.....


Having lots of ideas running through my head trying to fatham what it could be so ive been and had a look.

Slack chain.........

Even though i adjusted it saturday and have done 80 miles since.

Ill adjust it again tonight and see what its like tomorrow. I planned on replacing it in a few months but i guess it could be more shagged than i had given it credit.

Slack chain is a possibility. Seems to screw loads of stuff up

I wonder if the clutch is not full disengaging for some reason?

If you hold the clutch in with the bike in first gear while stationary, does it pull forward at all?

Never had that issue on the range of older SV650s I've owned.

Weirder that it does it when it's hot though - as generally the clutch will drag more when cold if the oil is a bit thick.
Though, possible you've then got bits expanding (maybe even a warped clutch or something?)

Has it got oil in it?

As Paddy says - the chain can cause all sorts of problems you wouldn't first expect.

If the clutch is disengaging drive properly, then it shouldn't be an issue as the chain will be disconnected from the gearbox.

One thing I would definitely look at it is cleaning the linkages of the gear shift mechanism (squirt of WD40 on each ball joint and move it around - add some silicone spray/grease later to ensure it stays properly lubricated).
Thinking about it, had similar symptoms on my zx6 which that solved. I was generally clutchless shifting which is why I hadn't initially thought of it.

My old YBR125 did the exact same when the chain was slack

Seemed like there was no pressure on the front sprocket when the chain was slack or something.

Whatever, I used to watch for it as a reminder to tighten the chain!

Not normal IMO. Certainly my SFV doesn't act the same.

My Street Triple did this until I adjusted the chain and lubricated the gear shift linkages.

Now it's fine. How you're riding is not really advisable, but most of the time you can get away with it.

The guy in the dealer is kind of right, because you should really match the gear to the road speed, and not come to a stop and then change, but it probably can be fixed if you strip and lube the gear linkage and make sure the chain has the correct amount of slack.

Will do. Worth ruling out for the sake of 30 seconds with some WD40!

Ive adjusted the chain and doused the mech in WD40 (Not regreased as I have no electricity in the garage until i get the roof done and i didnt get home until half 8) and it dosent seem as bad now but i will keep a close eye on it. I can replicate it when the bike is stationary (i guess this is normal but my bandit was always happy to go from 3rd to first at a stop) but it seems OK when moving slowly.

I'm going to keep a close eye on it and hope my box dosent exploded the day after the warranty expires.

Yes slack chain and dirty linkage can cause all sorts of problems.

Also change the oil if it hasn't already been done. Not all dealers says the oil been changed when in fact it hasn't!

- yes, you are entirely right, of course. My bad - not sure what I was thinking about there!

For the OP: You've paid a premium over a private sale - so I'd get them to sort it, if it's still causing problems.
