This week I just passed 2 roadblocks. Phew~
btw, many 60mm piston and block are good enough. The problematic parts are crankshaft, conrod, piston pin, valve, valvespring and etc.
Why??
because the racing piston and block can tahan the horsepower, but the other engine parts cannot withstand! 57mm block still can, as FZ150 is using almost identical parts like LC. 58.5mm and above creates too much torque for the other engine parts to handle. Of course you can use (I am using too), but keep the rev low when you do your daily ride. Go full throttle only if you need to get serious (aka have fun!)
and never use racing spec stuff, because they are aiming to create power above 10krpm (cubprix bike goes 14krpm). When ppl lack of low and mid range power, surely ppl will pull the throttle hard for high rpm. With this, I can guarantee the engine parts cannot last more than 1 year.
That's why I always like people to custom made the parts for my LC. I want good power within 5k to 10k rpm, not anything beyond that.
Bizzy, as for the break-in, just follow the steps in mototune website. My piston breaks in damn well for 2 times ady. (Bee Hock checked for me)
recently many roadblocks d ler.. i also dunno why.. but my fren send me sms saying got 25 prisoners break out wor... thats why got many roadblock...
u read and see wat bizzy wrote about the break in.. if correct means okay... =)
if now my bike wan to try break in can ar..? LOL..
no point d right if try to do.. my mileage ade 5k now.. LOL..
