engine longevity?

[Anonymous]

Does increasing the engine performance from stock decrease engine life? Including just the minimum of 4 into 1, jet kit, and pod filters, but I am mostly wondering about mild big bore kits?

AS long as the build is within the engines tolerance, and your not beating it to death when you ride, there is no reason that a mild build-up should not last as long or longer than stock. :twisted:

Still takes the same amount of power to drag the bike down the road at a set speed, stock or modded.
depending on what is done, a modified engine can last longer, depending on what has been done.
you can ballance and blue print a stock engine using premium after market gaskets and replacement parts and have a engine that will last way longer than stock.
how long a engine last depends on how it is used, and cared for.

All the above is good advice. A mild big bore piston kit will create a little more heat if ridden harder. If you plan to use the extra power often, you should consider an oil cooler. If you ride the bike "normally" and just open it up for a quick blast now and then, I don't feel the cooler is a must.
That's how I ride my 1000 with similar mod's and I had over 100,000 miles with no problems. I'd like to suggest another good mod: for a good compromise between horsepower and torque, get some slotted cam sprockets and set your cam timing to 106 degrees each. This will give you the widest powerband and overall best performance without sacrificing ANY reliability.
The biggest threat to engine life with these mod's is a poor job of re-jetting. Don't just do like some have and install the jet kit set at the "base settings". Base settings are commonly way off. Test and do what the plugs say to. There's lots of help here if you have trouble.
