    Hi, just picked up a lovely low mileage (22000) 1993 zzr1100D for peanuts. it goes like a stabbed rat. Its a lot of fun. What's not so much fun however is the vicious head shakeing under braking and if you take both hands of the bars, think bull riding and you get the idea. Tyres seem good if a bit old and no obvious clonking or movement in the forks or head. This is my 2nd zzr1100 and the other one didn't suffer from head shake at all.
    Any ideas before I drop it in the garage and part with my hard earned?
    cheers. Roy

    The forks seem ok (not that iv done much more the poke and shake them). The rear wheel is good possibility though as iv not looked at that at all apart from checking tire pressures. Il check that in the morning and give an update. cheers

    Yes it has the balancing weights fitted. That's a good video thanks and watching that reminded me that in the paperwork that came with the bike was a receipt from a couple of months back for a set of fork seals. I wonder if the bloke I brought the bike from fitted them himself and buggered up the refitting of the forks. I think a day of checking everything on the bike is on the cards.

    Well I spent a lovely few hours up to me ear oles in 20 odd year old brake calliper grime today. Out of the 8 pistons on the 2 calipers 5 were seized solid and the other 3 were sticking. Took me almost an hour to remove one of the caliper pins. However patience and brake cleaner won and now iv 8 working pistons and lovely responsive brakes. The shakeing head is 80% better but can't say I trust the bike completely yet. I'm almost certain new tyres will remedy the other 20%.

    Are the handlebars lined up with the front wheel ? could be twisted forks.

    Might also be the back wheel out of line.
    I only have one viceā€¦I lie.
