Bandit k2600s

[Gavsta88]

Hi Everyone,

Having a niggly problem with the bandit. When im going up to and over 8k revs the needle jumps around and it sounds rough when it does it. Almost like its spluttering/misfiring.

Does it in all gears, warm or cold. Sure it wasnt doing that over winter

Hello! Mine does the same around 5-6k rpm i googled it when i first noticed it and found its a common bandit/bike issue at varying rpm ranges. Same bike also k2 600s blue

At the moment i just power threw it and its smooth after that range again.

Would be interested to hear if you find a solution so tagging this thread for updates.

Partial success.

Found a loose bolt on right hand side, front engine mount bracket. The bolt with an o-ring was way out not even touching the o-ring! nipped it up.

Quick test ride after allot of vibration is gone and can happily cruise at 70 mph now without getting good vibrations in the nether region.

It's still got a noticeable vibe on hitting 5k rpm, so perhaps another bolt loose or this one still isn't tight enough didn't want to horse it up to much with the entire weight of engine still on it and it only being an Allen head.

Should i take the weight with a jack and nip it up that way or is it good to go as is?

Also i did check all the above and all seems well.

Hopefully a bit more persistence and a few more nip ups and its sorted.

Thanks for suggestions.

Edit-

Airbox cover is stamped suzuki 31fo not sure if thats standard.

You will probably find a similar number on the side of your carbs, looks like a standard airbox.

As for dodgy wires, there are 3 or 4 plugs that go under the tank where the frame meets the headstock. The big yellow one can cause a boat load of issues with starting and running.

When I first got my 1200, the day before my mod 2 training started and then test the following day, I changed the spark plugs in mine only to find the damn thing wouldn't start.

I had inadvertently disturbed the yellow plug. It took a few hours to work it out but once cleaned and put back together it fired up.

Always worth a check if you suspect electrical issues.

Certainly worth a shot. Will save that one for the weekend cba taking tank off again after work.

Also anyone wana judge the spark plugs, have a pic from a month ago:

ngk iridium

Sorry crappy phone pic:D

I was told to just use standard plugs and change more regularly with the 1200. I'm pretty sure the iridium don't work well on the bandits.

[evilbond]

Might still have orig plugs in shed, will try them too ta.

Big discovery i think.

Found the exhaust can itself is rattling from inside, on removing it i've found the inner liner is loose. On tapping the exhaust you clearly hear a metal to metal rattle. Or at 5k rpm is rattles. Before or after not really noticeable.

Inner freely slides out till near the end. End of the inner tube looks to be slightly damaged.

Need advise how to fix this or if i have to replace.

Thanks.
