bad petcock or carb?

I live in Yuma, Arizona so therefore they are US gallons. We are near sea level and below sea level where I work. --- In DSN_KLR650@yahoogroups.com, "Eric L. Green" wrote:

I have to run the crappy California gas........that is where ours comes from. I also have the CA smog equipment.

Most of you guys getting 55+mpg on your US gallons is a bit hard to take. 3.78 litres or so to a US gallon I think isn't it? I still think in mpg and do all my calculations accordingly and the best I've done is 55mpg but there're 4.54 litres in one of our gallons so I ought to be getting about 65mpg on my 2000km old '04 model. I wish!!

My A14 with 26.3K miles get about 45 miles/gal. However, I've got a 14 tooth front sprocket & a Dyno Jet stage 1 to eliminate lean surging. I believe to get >50 M/G you probably are running closer to the OEM lean settings & stock / or higher sprocket ratios. Also M/G is highly dependent on where & how ridden, tires, etc. I lose a lot of M/G on gravel roads due to tire slippage.

I get around 63 mpgImperial at around 120 to 130 kph on my '04 near Calgary. Ed

Could also be a clogged/kinked gas tank vent line. Or on a California bike, california bike the charcoal canister may be filled up. Quick test: after it has stalled, try opening the gas cap and starting the bike with the cap open. If it fires right up, you've got a venting problem. -pm
