I guess you're right, there is no need to find more power in a stock engine because they come from the factory with all the power thay can make. no need for improvement. Guess thats why there isn't any market for "aftermarket performace parts".HE HE HE
P.S I was thinking earlier today " I wonder if they make bigger cams for my VN700....... sorry for the confusion.
I think you are confused too, as I never said a stock bike can not be improved upon to gain a bit more power. If you read my first post here you would have seen I actualy said an earshaved bike can gain 4 to 5 horsepower.
My point , as you seemingly missed it, was that , yeah, an earshave with proper jetting will increase power as I mentioned, but adding to that screwing with the timiing an using high octane gas will add so little it really is not worth the trouble, as you will just create a bike that burns more fuel, (and expensive fuel to boot...) and runs rough at low speeds.
And I am sure you
know what your doing, but I lost count of how many bikes came into the shop that ran poorly all because of their backyard mechanic owners attempts at "making her faster".......
Secondly, we are talking about the Vulcan 700/750
, so good luck finding those "bigger cams". Granted , if we were talking about a Honda VTX , there are several companies offering performace kits with hotter cams, bigger bore pistons with high compression domes, larger valves, stronger springs, etc , etc..Even an older model like the CB750 has high performance items still available.
But I was talking about the Vulcan only here, and there ain't much out there other than aftermarket pipes and standard over bore pistons.
(also keep in mind that 95% of the members here are always going to be potentialy ahead of you in the power race as they have that extra 50 cc of displacement more than you)
Next I need to point out to all those that are confused that the "goats belly" is not a catalytic converter, or some EPA mandated power killer. In fact, Kawasaki refers to this part as "a power chamber" which , disregarding the hype, is in fact true. It is specificly designed to ensure power throughout the rpm range,
and is one of the better concieved exhausts ever offered on a motorcycle.
I should also point out the glut of aftermarket pipes for V twin cruisers are made more for looks and sound ... rather than gaining significant power.
And please don't get the idea I was trying to poop on your parade here, there is alot to be said for the "because it is there" reason to try and squeeze what you can out of what you got. Hell , I just read awhile back about a guy trying to put a turbocharger on his Honda Rebel...
What I was trying to point out was that the vulcan is, for its size, a pretty quick little bike, and can smoke many of the other twin cruisers on the market today, including bikes with almost twice the displacement....but that it does have it's limits and if you are looking for big gains in power, you really have the wrong platform to start with. You can shave your poodle , feed it steriods and take it to the dog track, but it still will be a greyhound that will win.
Another often avoided trick to shaving off some time from your 1/4 mile runs is to .............diet. If the average american is 20 pounds overweight, that's at least 0.04 seconds you can gain by eating and exercising.
Speed and power can always be increased to some extent, but keeping a bike dependable, reliable , and enjoyable to ride are things worth keeping in mind. You can spend alot of time , effort and cash making your bike "faster" but still someday some kid on a 600cc sportbike is going to blow your perverbial doors off and laugh at you....so speed is all relative you know............
