Yeah, i agree! The situation happened to me too. I had just rebore my block, change a new piston, piston ring, gasket etc hoping to get rid of the "knocking" sound but to no avail. Wasted $$. Skrg plak, due to new piston, I cant ride fast for say 1000km. Haiz.. Okay, nvm.. what's done cant be undone. Now face the future problems.
I realise the sound came from a lose con-rod (connecting rod). My mechanic says in order to change the con-rod, have to overhaul the bike. Is it true?
Got some doubts to be cleared:
1) What do they do when they overhaul a bike? What are the parts they change? Do overhauling include replacing a new block?
2) If replacing a new block part of the process, can it be excluded? Cuz my block had just rebore and piston plus piston ring had just change. It will certainly save some cash and spare me from the inconveniences of having to ride slow again.
3) I dont plan to overhaul any sooner but does riding a bike with lose con-rod post any dangers? (Eg: piston jam etc)
4) Do anyone has a visual aid (pictures) showing a connecting rod? I just wanna take a look what in the world is that.
** ATTENTION to FARIS: You mentioned some time ago that you just overhauled your bike. How much it cost? Is the price range between $400 to $500?
Hope to get response soon
Thanks!!!
