There is an ignition system mod or upgrade that can be done, it's called the "Wired George" mod. You can look it up on the net for instructions. I've done it on my 1981 KZ305 and a 1978 KZ1000. You'll get the strongest spark possible. Big fat blue spark!

I have recently baught exactly the same motocycle from M&P in Swansea Wales GB that was imported from the USA in 2021 - the l last owner was living in Seattle - Washington State Licence plate number 655157 . Does anybody know the history of thi motorcycle? to enable me to confirm the details so that I can register the bike in the UK. Thank you for posting the details of your problem in getting the KZ305 to run as I am having the same problems. Peter Blake.
