World’s Greatest Mechanic

A few weeks ago I started off on an unexpected odyssey. I was simply going to replace main jets, as per the instructions, to match my cone filters, learn to sync my carbs and drive off into the sunset. I figured four hours to a day max.

Well here I am two weeks later and a little wiser. After I replaced the jets I took off for a test ride and came back to adjust the needle position. I had already established a good idle and throttle response was excellent except for a flat spot just past ¼ throttle.

As the weeks rolled by and with each carb cleaning and bench sync the bike ran worse. I would dismantle them, clean everything put them back on and sit there looking at it afraid to be disappointed yet again. I would get up the nerve and it would be worse still. I spent hours on the internet looking up anything I could find on the Mikuni BS32 Type 2 and read volumes. It got to the point that I found myself staring at the bike, having double and triple checked everything bewildered that it would no longer even start. It would spin like crazy but not start.

I checked vacuum hoses, throttle stop and mixture settings, wiring, and the coils, nothing. I had run all kinds of carb cleaner and additives from SeaFoam to Techron and every time I took the carbs of I sprayed WD-40 into the manifold so they would go on nice and easy, I was fast becoming an expert at removal and installation of these carbs something I never set out to do.

Last night I looked into ignition systems figuring maybe I needed a new component and plug wires. I went to the NGK page to see what they had and read up on their products. With NGK on my mind I made a last attempt and resolving this problem and pulled the plugs to have a look. Surprise, Surprise, all four were fouled. With all the stuff I had put in combined with the days of idling, with a fan, never burning off any of that stuff. And the fact they needed to be changed any way it was a cumulative sabotage of all my work. I put in the new plugs and barely touched the starter and she started right up. Within fifteen minutes I had the carbs synched and idling perfectly.

Moral of the story…I don’t have one yet, but it has been an adventure.
