Default baja hard to start in the cold

i found that when it got cold enough and my machine was fussy to start popping off the air filter and holding my hand over the mouth of the carb works great, i know it sounds like alot of messing around but with todays carbs only using an enriching choke you dont have much choice. if you still run the stock air box unscrew the air horn from carb mouth and hold hand over carb opening. works every time[img]i/expressions/face-icon-small-smile.gif[/img]

Different octanes burn the same. No if ands or buts. The only difference is their resistance to detonation. It does not achieve this from a different burn


The antiknock ability is related to the "autoignition temperature" of the
hydrocarbons. Antiknock ability is _not_ substantially related to:-
1. The energy content of fuel, this should be obvious, as oxygenates have
lower energy contents, but high octanes.
2. The flame speed of the conventionally ignited mixture, this should be
evident from the similarities of the two reference hydrocarbons.
Although flame speed does play a minor part, there are many other factors
that are far more important. ( such as compression ratio, stoichiometry,
combustion chamber shape, chemical structure of the fuel, presence of
antiknock additives, number and position of spark plugs, turbulence etc.)
Flame speed does not correlate with octane.

Temperature=Heat=Energy
