That's bollocks. I've tried to do it with and without the tool, monitoring progress with a 4-channel manometer, and you cannot synchronise it accurately unless the inlet tract link is blocked. There is just too much interaction between the linked carbs. You can have one a long way out yet it has little effect on tickover. >Another tip I have seen is don't bother with the special tool and use >a 10mm soft wood dowel. If you like splinters of wood heading into your engine, go ahead. The special tool is a few alternating sections of rubber pipe and alloy tube threaded onto a metal rod, with a lever that compresses the pipes lengthways to block the tract linkages. I suggest you treat the "advice" you've recieved with a healthy dose of scepticism. Mine too, for that matter, but I had an XJ900F for 7 years and did all my own servicing after the first 2. The person who bought it off me was, and still is, very happy with the work I'd done and the way I'd looked after it. My feelings about what she has done to the frame are somewhat mixed. -- Chris VN1500-j1 (Gertrude) Twice the fun at half the speed. chris.desclayes at ffcc dot powernet dot co dot uk But minus one "f"

Well after phoning Yamaha UK and finding out the price of the 'tool' is 50 I think I'll make my own. -- www.ratrodz.co.uk XJ900 Trike GS850 Trike obet(a)jryfutbi.pb.hx [Rot 13 it] Some people are like slinkys.... no real use but it makes you smile when they fall down stairs!
