Sleepless in Seattle, installed Tri Spark yesterday
I orderded mine direct from the Tri Spark manufacturer, Steve Kelly, in Australia. It ran about 210 Bucks US, includng shipping and arrived in about 10 days.
Turned the 850 Commando into a great machine.
I could never get the left carb to run right with what now obviously was a faulty boyer. I know I could have fixed the boyer, but it was over 15 years old and always giving me issues.
Thanks to all in thre Forum who hepled me diagnose this issue as an ignition problem not a carb problem, back in January.
The thread was " left side pipe cool to the touch"
I'm getting one kick starts, even in 35 degree weather, smooth idle at 900 rpm, and good acceleration through the gears. bike sounds better too.
I'd say it is definately worth the money, and a very clean and easy installation.
