Yamaha Thundercat intermittent stalling

[Dannaz]

Hi All,

As per title, my bike came off its stand outside the house (we won't go into that, kicked myself enough) and damaged the left rearset bending it inwards towards the swing arm, so the gear linkage is slightly off and the clutch lever got slightly bent. While waiting on the parts to be delivered I have noticed intermittent stalling when sat in first gear, just seems to idle for short time and then dies off. Any suggestions what this could be and if possibly at all related.

I do have the parts now just need the weekend to come to fit them. Bike runs fine, idles fine and changes gear fine, just having these intermittent moments.

Any advice welcome

Many thanks in advance.

Cheers podman, I will look into this, they were prob done 10K miles or so, so prob due a check and clean. I have been getting quotes for major service including carbs, so it's been on the cards before the fall.

That's a good shout, it has a side-stand switch and did go over on that side, strange though as it's intermittent and not a complete cut off when it happens. The rev's dip and then it slowly dies off, as in starved of air and fuel etc.

But as I am changing the damaged parts I will check this out.

Cheers for input.

Sounds about right from what you and Evo8 have said, as changing gear is more clunky now due to wear the peg sits to wear the gear lever is and the side-stand and switch are more exposed, so I'm guessing it's when I apply to much pressure, maybe worth replacing this as well then as could also have taken impact damage.

Much appreciated.

It's happening only when in gear and clutch pulled in, in neutral bikes absolutely fine and idles fine. When it does it, I can feel the bike trying to pull as though it's on bite point, although clutch lever is all the way in. I have noticed the lever is really slack and moves about since dropping it, also where the cable runs into the lever housing it now has play.

I have a new lever so will fit this and hopefully be able to adjust it.

Cheers for the input, as I am not the most technically gifted person, do you reckon the new lever and correct adjustment will sort this? or will I also have to adjust it at the clutch on the engine as well?

once again thanks for the input, been doing my head in, as when it happens its been a case of Starter button/high revs/clutch release and go in one swift move.

Yeah, I bought the clutch lever to replace it as it's bent back on itself. So this will be getting done first, and then I will adjust from there see how I get on. It always had a little bit of play as the MOT tester picked up on this, but it was comfortable for me, but now it's just excessive.

I will update the thread when I have made the changes.

Thanks to all that have contributed
