Last July I changed my ingition, went to the Ultima Single fire ignition worked great till this past Saturday. Cranked it up, got the helmet and the wife and was ready to roll and fired it up again, No fire to the rear cylinder, tried changing plugs, wires, traced all the wires to module in nose cone, all good. switched the blue wire with the pink on the coil, rear cylinder fires but not the front, was told by ebay person that I bought from, he said the coil seems to be the culprit, (Ultima coil but made in China) but he now has them that are made in USA. I have a ohm meter but I just don't know the correct was to test it. Is there anyone here that can give me the correct method? I hope its the coil instead of the module, I bought it as a full kit, coil is much cheaper to replace....

Got a Power Vision friday and put it in the bike. It had a preloaded map for the 107 motor I have.

Went to riding the bike. When I got to like twist the throttle in 3-6 gear. from 2000 -3000 rpm, It pops, and missed so bad it will bearly run.
Got both new 12mm lambda sensors too.
Bike seems to be putting a lot of heat off.
Trying to get another map. But don't know how long that will take. Getting kinda scared to run the present map that is in the bike.

If I'm in 6th gear and running about 2200 rpm and twist the throttle hard, it starts missing so bad its like its gonna die till I get like to a little over 3000 rpm.
Has nowhere the power it had with the Thunder-Max.

Wished we had somebody here that knew how to tune one.
Heard of a few folks tuning it with the VE tables.
I know nothing...

How much would gas mileage be affected with a badly worn rear tire?

VIDEO: Motorcycle camping in the blizzard
February 11, 2013
By Troy R. Bennett

The roads leading west into New Hampshire were slick last Friday morning. The leading edge of the snowstorm the TV weather folks were calling the impending “Snowpocalypse” or “Deathstorm ’13″ in their typically understated fashion, was already dumping snow on me. I was astride my Russian-made Ural sidecar rig headed from Portland to Fryeburg. It was cold. My breath was freezing on the inside of my helmet shield, making it tough to see. Each time I passed a truck, whiteout conditions ensued for a few moments in the billowing powder. I was careening toward the state line to meet up with three other three-wheeled cyclists. We were going camping.

That’s right: camping.

To be fair, we planned the trip last fall...
