hi all
im struggling with a problem on my kz1000 a1.....when i bought the bike it had a nameless[loud] exhaust the bike ran badly so a standard exhaust was fitted,new points and condesors fitted,standard airbox,new carb intake rubbers,cylinder compression checked[ok]carbs cleaned and balanced, the bike still ran badly,a pair of ign coils borrowed from a club member[cheers gez]have been fitted and the bike still runs like a bag of spanners,the bike did smoke a little when i started it today but it has stood for quite a while without being run.....i did notice today that after 5 to ten minutes running[badly] the left hand cylinder was quite cool[i could place my hand against it immediately after i switched the engine off] the right hand cylinder on the other hand was very warm as you would expect......any ideas what it could be lads...any help gratefully received
cheers steve

Plugs?
Dyna s will be a huge improvement on the points.
Are you getting 12v at the coils?

Hi Stephen, a lot of the old zeds do this but will generally fire up after a minute or two i guess you have swapped leads 1+4 round to see if its these, maybe some new plugs, check the valve clearances, also check you have 12 volts going to the coils, i had this with my thou and done all the things you have and more and it still used to do this right up until i put an exhaust system on that was almost like the originals and never suffered this problem again.

Swap plugs 1st - then 1 & 4 leads..... see if problem follows either item

fuel heights, pilot system, choke system, plugs, leads (probably built into the coils).
Pull the plugs out and see what they're like.
