[QUOTE="C5Performance, post: 95716, member: 2938"] Getting to why engines have the same basic curve: Take a CBR1000RR race bike and compare to a Trail 70. Do they have the same curve? YES Do they have the same horsepower? NO How can they share the same curve? Ask yourself this question.... Does electricity travel faster on a CBR1000? NO Do they both use pump gasoline? YES Do they both idle around 1,000 rpm and end up over 5,000 rpm? YES So why would they use a different curve? "well the CBR has more power and goes faster" Remember, the engineers have designed the transmissions so gearing matches the horsepower of the engine. The only difference would be an outside force such as HILLS, WEIGHT OF RIDERS, FUEL OCTANE which means the load can change. All things being equal, the timing requirements of most engines are virtually identical. We retard the timing only when the external load changes the rate of fuel burn. Make sense? [/QUOTE]
