400/4 is popping & banging with poor mpg where to start?
K2-K6:
Woooohooo Ted, now it'll feel good to ride :)
At least not too hard to correct and get you back on track.

I will need to trim down the HT leads as I have left them slightly on the long side for the first fit!
Can't wait to try the bike on a run to Ashbourne probably tomorrow.
YES, YES, YES, YES. that's four yes's for four cylinders!
To be on the safe side I plan an oil change asap in case of sump dilution as a result of 115 miles on 2 cylinders.
Moped power to 400/4 now the HT leads fitted in the right order.

Ted, Be as generous as you can with lead lengths, as you may need to re-attach the caps one day, and the leads do deteriorate/ get mangled when you manhandle leads to get the plugs out! Having some slack will help.
Have fun,
Jerry
