Any time you extract more power from a motor, the longevity goes down. That's a general rule and dissipates when you build everything stronger, but sooner or later, after adding a bunch of power, you will find the weakest parts.
Yeah, I'm really on top of maintenance and oil changes so maybe I'll stop at the bazzaz, exhaust, and intake to make sure i get the longevity I'm looking for or until the warranty is up! Most of my riding is 40mph to 50mph on a couple of stretches omw to work so maybe the top end gains wouldn't benefit me too much.
There’s not much downside. In theory, more power = less life, but we’ve never seen a motor fail on these proven mods. In fact, it’s our personal go-to favorite combo, and we value reliability over all else, because it’s no fun if it’s broken....
My son and myself purchased most of our stuff from mnnthbx.
They looked after us really well with prices and freight to Australia.
We are running 143kits with race head and cam lightened primary plus Bazzaz and one Bazzaz AFM so we could build maps for both bikes all from Mnnthbx.
We live in a country area so the Zs don't see much city riding it's mostly country roads with speed limits 80 to 100kph so the bikes are working hard and we give these little bikes heaps.
If you keep on top of oil changes and valve adjustment I can't see that there would be any problems.
At some stage I'm thinking or doing the 155 crank as well but for the moment the 143kit is heaps of fun and makes a big difference over stock 125.
