As above all the best-

Hi went through the same thing with my fzs600 --even had the carbs cleaned at shop no change--havin been through the electrics etc still convinced it was fuel i borrowed my mates carbs off his bike and was up and running on all four in no time --bought a set off fleabay happy days good luck-

Got spare set s4rm/3t Bahco ratchet spanners new in box- also Beta Easy 1/2" drive socket set and a Beta Easy 3/8"drive brand new --Spanners 28.50 posted --socket sets £38.00 each posted --apologies if am breaking any rules jus got some tools goin cheap seemed like best thread --

Wondering if later engine will fit my bike (99 plate) am sure i read on here somewhere that it would maybe need to change couple of plugends any ideas ??am not upto complete stipdown to repair gearbox thanks in advance--

Well chaps clutch is fine guess its gonna be sump off and see what i can see (oh drained the oil it was debris free )--

Hello foccers been out for blast with my mates -set off like a twat missed 2nd gear knocked her up a gear destroyed something inside --can start bike up with clutch pulled in sounds fine--but when i release clutch lever sounds like a bag of spanners and the noise wont go away--i suspect its the clutch although it sounds like the gearbox side of the bike --ill check clutch  in the morning  in the meantime any suggestions /ideas welcome-thanks in advance-

Ok chaps got the xj to run quite well now my only gripe is when  i release the throttle it is slow to let off the gas .the carb snaps back nicely -throttle grip and cables all snap back as they should --bike ticks over as it should--bit stumped now --any ideas please --?

Thanks Trebus will get into it tomorrow--

connectors look good cleaned each one individually strangely found a live wire attached where the coils bolt to the frame --unbolted it and bike wouldnt turn over-put back in place bike spun over still only firing on two--got day off tomorrow will try again losing hope fast thought the electrics on my lancia beta were bad --

I'd say unfazed is on the money. If it's a project bike that hasn't run in a while it makes sense that a ground might have been missed or the wrong connectors were plugged together. Another possibility could be that a component in the ignitor failed short so too much current flowed but that seems less likely.

The igniter boxes on these are a bit fragile but are repairable. The transistors can be replaced by hand if you know what you’re doing. Normal failure mode is firing on 2.

As suggested, have a check through the wiring for any corrosion which will cause high resistance.

I don't think he's looking for corrosion. I think he's looking for signs of excessive current flow so burnt/melted connectors or wires. If the problem was caused by plugging the wrong connectors together or missing a ground the wiring could be damaged as well as the ignitor

fitted another igniter box --immediately started to get hot again only firing on two cylinders 1 and 4 pleeeeeeeeez  help---

tidy clear un marked no cracks or damage £35.00 posted uk mainland only thanks

did a full set of exhaust studs i used a decent pair of mole grips and a medium size hammer--gently rock the stud whilst tappingthe end with the hammer dont be afraid to give them a good crack your going to replace them anyway--always had 100 percent success rate with this method --
