Pleased with mine too , instant starting on my 72 and noticably better than running standards as I do on the others .

Worth it I think !

Had 'em in me Black Z1000 for a year now.... no probs.... May be OTT for a standard set up (points etc) but ......peace of mind

[Reecy]

Oh yes these are definately worth getting

My zeds have them and starting which was a bit of a lottery previously became much more certain and my Z1000A2 starts and feels like a new bike

got to get yourself some.

having trouble working the sparkplug.co.uk website. can anyone tell me the correct iridium plug type for z1 and z650 b1

[steve bowdler]

Al try this

BR7EIX Iridium £5,89

B7EVX Platinum £5.75

[MaineKZ]

Shoved a set in a day or so ago - difference is noticeable particularly on start up and at low revs - very nice.

The Z1 takes BR8s not 7s - so says the NGK plug finder anyhow

All in all - worthwhile

I've tried both NGK and Denso iridiums, both are a noticeable benefit, but on one of my bikes ( not a Zed ) , I've found that the Densos are markedly better at igniting less than perfect mixtures.

One word of warning, Iridiums, especially with Dyna coils, are almost capable of igniting fresh air ..... you can have a very ( too ) lean mixture and you don't get the typical hesitation symptoms, until its a bit too late..

So even though they burn clean and are supposed to last for 10's of thousands of miles, still make a habit of checking the colour once in a while.

I've used iridium's on a bike with worn piston rings and I found trouble with starting due to fouling the number 2 plug. Once I got it going they were noticeably different especially at low rpm/speeds. I changed to iridium's on a my Z1A which as recently had work done so no piston ring issue and I wouldn't use anything else now, really smooth.
