I can't balance my carbs. Picture below:

1-2 is out of balance with 3-4. Anti clockwise on the centre screw should help with that, but it doesn't. I've screwed it right out to where the screw is wobbling as it's lose in the seat. Turning it the other way Makes 1-2 bog and ultimately the engine stall.

I can't get 3-4 to shift at all, they're up at the top of the gauge always. They respond normally to throttle, coming down before easing back up. Choke brings 3-4 down a bit, and 1-2 isn't changed much. They looked roughly equal on the eye test before I put them in, just open on the tickover.

I can't get the tickover down below 2.5, I think I'm right out on the tickover adjuster too.

Any suggestions before I pull the carbs out and have a look to see whats up? Things to look at when I do? Bit of crap stuck under one of the butterflys I see as a maybe, can't think of anything else.

The background: carbs are a different set to what was in a week ago, cleaned. I balanced the old carbs only 3 weeks ago, no issues. I've got new spark plugs in. New carb inlet rubbers. Exhaust headers reseated. New coolant, new oil. Coolant rubbers and rad replaced.

Thanks if you can help, I'm having a bit of a mare over here, it never seems to end.

I've done something daft or damaged my bike after a cracked radiator. Still overheating I think, causing the oil filter to leak. If anyone fancies reading and giving me some pointers, any pointers at all, that would be much appreciated.


I've replaced a cracked radiator, and all the 25 year old rubber pipes. I currently have the aftermarket temperature gauge saying that the temp is ok at the top, but the oil filter just chucked oil everywhere, and it's acting like it's overheating down there. Seems strained with the throttle open. So I've done something daft, I am not sure what. Or damaged something somehow. Would the oil leaking from the filter do this?

These are connected correctly, right?

I haven't got coolant coming out anywhere. It's at the top when I open the fill whatsit under the tank, and the level is right where I left it in the overflow.It's doing the swirly thing looking at the coolant with the cover off, so I think that means it's circulating. The coolant has come out clean, the oil doesn't have any coolant in it.

My number 24 on this is maybe 2cm too long, so it's a bit bent. Looks like it's open though so I didn't worry about it on install. Pics on the Imgur link.  I've got it going to the top of 9 on the diagram, is this correct?

My plan at the moment is get the oil sealed and see how it behaves. I don't know if a leaking oil filter would make it behave like it is, but it sounds unlikely. I'm at a loss if that doesn't sort it. Busto engine somehow? Anything else to check?

Thanks if anyone can help.

*Yes I will do some painting and cleaning in there and repainting while I've the chance. It's all off now, tomorrows job is clean and paint.

Any tips for these little bleeders? I've had the heat gun pointed at them, penetrating oil repeatedly, and they still won't release with as much force as I dare. I've snapped a few in the past, a serial balls up by me.

I need a nose cone sub frame for a mk1 FZS600 (1998). Has to be straight obv., but skanky is fine

Mine hit the deck quite hard and is bent... again

So mother of god, that's hard to get out of the frame. Can anyone who's done it give me some pointers? I'm well stuck, and of course it's not something I can drop in at the shop.

The bottom one I've got, as there are some big groves scored into the frame so I can get a purchase behind it with my makeshift drift.

I'm going to go down to my local general purpose tool shop and see if they can sell me something more suitable to use as a drift... any good tips on what's best to use? Bend it, file it sharp along one edge etc? Would a heat gun at the top help?

How about if I just drilled through the damn thing? This would make it easy to flip off, but of course I'd go into the frame behind. Would this have safety and handling implications?

Thanks if you can help. I'm having a bit of a tilt at the moment, I thought it would just come straight off and I've been at it for a good 3 hours. I've done it on my little FZR before and they just fall off, I don't get why they have to be so tight - and so f**king inaccessible - on the fazer 

Mk1 FZS600  rev counter doesn't always shows the revs, it shows 3k, then the revs, then 0k.


I've had the engine out to drill out an exhaust stud and do a bit of painting, so I'm guessing I've not reconnected a wire, or pinched something. I can't find anything obvious though, and can't find anything in the manual. Can anyone help???

I'm after one of these... I'm sure there's a proper name, but this is what I've decided to call it I mean the cover on the engine on the right hand side, the one furthest forward that covers the gears that link the crankshaft to the starter motor.

If you've got one... price me up, ta.
