Default does engine last with big power kits?

I've been back and forth about building the glide up to 100hp and torqueor better. Expensive I know! But as I go to my mech, throwingideas at him he constantly shoots me down with "We could do anything but it will kill your motor and you'll buying a new one and tranny well before you get decent life out of the bike". Is there any truth to this? Are any of you out there with performance heads, better cams and big bored cylinders getting the life you want and expect out of your motors and trannies? Even if money is no object why spend 10g's on something I'll only get 30k out of. I need and appreciate more power and all but.......

Maybe a better way to pose this question is "what canI do to hop up my motor and still get 100k miles out of the bike with regular maintenance?". I am strongly considering Andrews 26's but what else?

I'm not even going to get started on that stupid extended warrantyI bought into! I know I'm not the only sucker here but I still strongly consider trashing it! I somewhat understand but not fully. The thing won't even cover a SERT! Just does'nt seem or sound right.

Thanks to all with any input, enlightenmentand/or jokes.

GOOD, BAD or UGLY

Longevity mainly comes down to the person behind the throttle.Upgrading one area w/o doing everything else usually ends in trouble and a upset owner.Mild upgrades above say EPA regs are usually very safe as long as common sense,proven kits,compenents,and routine maintenance is followed.

In the real world any time you up the horsepower via compression or other means you decrease its lifespan and other parts that are in conjunction. You can do as pittguy says and be gentile, but then why did you do it in the first place?

I totally agree gunrunner. why make the changes if I'm not going to use it. I guess what I'm saying is why don't they make kits that truly stand up to what they are built to do with longevity?

Quality parts last if properly maintained...ya buy junk that isn't properly matched and ya get what ya pay for. Also if you don't abuse it it will last. Revving it up to what it is designed for is not abuse.
Whatever you do thoughtfully planned build by a quality shop should not be any problem. This means the builder pays attention to details...such as set the quench, cc the heads gap the rings and have the piston to cylinder bore correct. Finally break it in right.

That's what the mild build is all about. 100/100 is pretty safe. Beyond that, I'd be thinking of a Timken conversion at the very least.

Don't need the Timken conversion. Go with the GP Designs crank support, I know quite a few guys that are using it with good success including my bike.
