Re: Re-jetting a BF75
You cannot get 10hp from a 7.5hp by rejetting (unless somebody had a 10hp and screwed up the jetting to make it 7.5hp). The only reasons to change jets are if:<br />1. Some Bubba had installed the wrong jets and you are putting the correct ones back in.<br />2. You are moving to a different altitude from which the jets were designed for.<br />3. The jets were damaged by a careless mechanic.<br />4. You have made extensive modifications to the intake, exhaust, cam/valves, or combustion chamber design (which is usually the difference between different horsepower engines of similar displacement) causing an increase in airflow which will require different jets.<br /><br />If you need more power and your engine is running correctly, buy a bigger engine - it will be cheaper.
