Seized Counter Balancers

Hey ho peeps

Have a brutal case of engine rattle under load, so am looking to check the counter balance adjustment. Had a go a while back, but couldn't get the buggers to shift, even after using penetrating oil. Have a service due soon, so seems like a good time to have another go.

Has anyone else had stuck balancer shafts? Tips? Suggestions?

Many thanks y'all

Nick.

From a number of the pictures of bikes from your side of the pond, I would have to say you'll probably need a chisel to knock off the crud that is freezing them up! 4:

this is not unusual or a counter-balance problem. The ST1300 V4 will rattle when loaded and you open the throttle under 3.5k rpms.

Mix equal parts of ATF fluid and Acetone, this is one of the best penetration oils known to man!
Use a needle oiler and put several drops on the end of the shafts, arms, and bolts, and let it sit over night, in the morning you should be able to use a good quality (large) screwdriver to loosen them.
And yes, the CB adjustment WILL remove alot of your rattle if its out of adjustment.
You may also try doing a TB sync, as this will help smooth things out as well.
Could it be your hearing/feeling your clutch rattle?
