Hmm, very strange that Yamaha recomend something thats not good for the engines and also all other engine manufactorer also do recomend the same as Yamaha and also all school books recomend?
You really belive on all what Americans writing on the net? Have you ever heard about some good americans bike engines,LOL, i guess not.
If you have knowledge you will know what happends if your brake in hard, do you really know it?
You must give the parts time to fit eachother before you can push fully load on them, or else you can get metal rip off from cylinder walls, piston and rings,this because the parts have not been fully fitted to eachother and the contact surfaces are sill rough, this can couse the rough surface to brake the oilfilm on cylinder walls and you will get metal to metal contact and some metal will be ripped off and makes scars.
Have you all read and understood fully out Motomans explanation?
He have some funny ideas, just look on his page and you will se he wrote this too: "Smaller Intake Ports Gain 7 % More Power" So then i suggest you all who belive Motoman will remove one of your exhaust valve and on of your inlet valve and you all get 7% ore power,LOL, just try and see what happends
I just try to help you all, but its up to you if you want to damage your engines or not. I dont say the engines wil be so damaged that it will not run after hard brake in, but you will for sure shorten the life of your engines a lot.
Sniper, i have brake in my bike just after the Yamaha book and mine is still the fast 135km\h (real km\h) i think is your riding styles that makes your bike faster, you probably ride like me, high rpm, fast acceleration and fast,right? I noticed everytime i come home from work(i work 5 week on\5week off) the bike is slower and its because my girlfriend has ride it and she rides slowly and no high rpm, so the engines get moore sooted inside, so i need a god day to blow and burn out this soot ad then the bike is good again.
Maybe i should explain in an easy way, come home from work and jump on your girlfriend and try to dry F... her and you will get the resaults, try instead to warm her up and get her W.. and you will get an another reaction. Maybe a bad comparison but tru
