[QUOTE="Nigel Spaxman, post: 115877, member: 2907"] I used a typical single choke lever made for Amal carbs on a Triumph Bonneville, with a 1-2 cable splitter. I had a few of them around, most people remove them from Triumphs. The Amal lever is not ideal because it is designed to give about a 30mm cable pull. Maybe the MZ one Stu used is better? The pull required for the Mikuni enrichener is only about 5mm. It works ok with the Amal lever though. Last year my bike was becoming hard to start. It was always a first kick starter. I was travelling on the Ferry to Victoria. I had to kick the bike about 10 times for it to start in the morning and also later to get on the ferry. After the ferry ride I was dreading starting the bike. I moved the lever to operate the enrichener circuit, then I noticed the lever sprung back a tiny bit. I pointed this malfunction to my passenger and she immediately understood the problem. I realized the friction screw in the center of the lever had backed off. For the last few weeks the only reason my bike wouldn't start was the enrichener was not working! I took out my screwdriver, tightened the screw, operated the lever, and the bike started first kick, and has been doing so ever since. I doubt I will make that mistake again. [/QUOTE]
