Z1000 MK2 Timing data ....any one know ???

[johny brando]

Z1000 Mk 2 ignition timing data .......I can't seem to find it anywhere CAN YOU PLEASE HELP ! I know it's fully advanced at 3400 rpm thats all I can find on it.... but I'd like to know where it is in degree's when it's Retarded & what degree's BTC it is when it's fully advanced & if possibly at what rev's doe's the Advance start to cut in. I'm running it on a 900 & it runs OK but I don't know if it possibly could be doing any damage or not. All the data's readily available for a 900 but ziltch for a MK2. I'd be grateful if any one can shed some light. Cheers. [/b]

book says 10 degrees BTDC at 1000rpm to 40 degrees at 2350rpm

Full advance is 40 degrees btdc on all the 900 and 1000's if you are going by the book on a std engine.
Once you have that set with a strobe the retarded figure is fixed by the mechanical advance and can't be altered independently without modifying the advancer.

Whilst on this subject, are adjustable cam sprockets
the ultimate for accuracy when mechanically retarding
the timing, or are adjustable cam sprockets only required for high lift cams?

Not sure what you mean.
Adjustable cam sprockets bear no relation to the ignition timing.
However! adjustable cam sprockets are of use even in a STD engine as manufacturing tolerances means that the cam timing is hardly ever spot on from the factory and degreeing them in can help crispen up the motor and find a little more power.

Thanks alot Chris !!! thats exactly what I was after mate. It really needed some one with a preferably a factory manual to answer that one. Now I can see where the timing differs from a 900 ( i.e. 20----40 degrees BDC & from 1500--2350 rpm) as oppose to the MK2 with a wider differential of ( 10----40 degrees BTC advancing over a longer period from 1000---3400 rpm ) Cheers

Thanks for that Rob . I'm not looking to alter the A & R unit I just wanna find out the difference between em... thats why it was Data specific questions. Thanks for your input mate. Cheers Johny B

Thanks Rob, you are simply the best
