Im Currently having that same issue with my sons sawtooth 200, were were out on a ride and it ran great until he was going up a hill and all of a sudden, if you were to touch the throttle it dies, will idle all day long but, any throttle and game over!
Typical symptoms of a lean mixture are: Backfiring as the throttle is closed (primarily during coast-downs) Lurching acceleration. White or light gray spark plugs. Requiring excessive amounts of choke to run/start. White or light gray muffler end pipes. Bluing (on chrome systems) of the exhaust header down-pipes.
The pilot jet actually feeds fuel to at least 2 passages. For example, with throttle blades closed, one passage will be on engine side, while the other on airbox side. The engine side passage is further "trimmed" or "metered" by the fuel screw. When throttle blades open to 1/8 or so, it uncovers the other passage and it will be 100% on.
First, they are heavy. Second, they contain a large amount of lead, which is bad for the environment if not recycled, and the acid that interacts with the lead is corrosive, should it leak from the battery case. Third, they have a limited number of discharge/recharge cycles compared to lithium batteries.
2 Answers Bike is cutting out and dies out when you throttle hard. symptoms of water in fuel, bad plugs, or flooding out. Pipes are black inside and black is coming out. I have put heet and foam in gas tank - put new plugs in and has not helped. only 2000 miles Posted by Anonymous on Aug 22, 2010 Anonymous Aug 28, 2010
