Hi guys, I just came back from jb to pump. Stopped at traffic light and engine noise went all beserk. Sounds like camshaft or piston? Rattling like noise? Any one in Yishun, would be willing to listen and enlighten me? Damn worried now. Scared jam only otw to school tmr.
If need to overhaul, likely cost would be?
Thanks guys.

Hey bro i stay in yishun.... Where u stay???
Pm me oso can. Willing to help

Rattling may just b the cam chain tensioner or cam chain itself.

If the piston eats up ur block sleeve, go rebore and fit new piston + rings. No nd for a new block.

How much is rebore plus new piston and piston ring? Cam chain or tensioner?thanks for the input!

Ok, was at my mech and he said it was tensioner and timing chain? Damage is $195. Excluding labour charge. Ok or not the price?

@dgray bro, like what you suggested, rebore and new piston and ring. How much would the cost likely come up to ah?

Rebore not sure. New piston cost, u go ebay for average quote. Dun like me got no time to check; end up paying more. Dun forget to include shipping so u can gauge.Good luck!

Im going 440 soon.... Hehe. Save money 1st.

@raskal 440? I was there once. Awesome power but I didn't have a deep enough pocket to maintain and it jammed. Changed back to 400.

@dgray Ahh, will look around. But my mech quote me about $120? Sounds reasonable?

$120 original piston? Tats reasonable. Wiseco high com piston also max $200.

Full set block + piston + ring + gasket u can get ard $600 if order urself.

yeah, original piston. but i cant do the repairs for that now ah. just installed new tensioner and chain, $300. have to save up before i can change my piston ah.

If piston stil ok, no nd change bro. Save where we can.

$300 for the tensioner n timing chain??? Or with the piston???

And why la ur piston jam during ur big bore period??? Wat telah happen??

@raskal no no, not just those 2. 300 includes the 2 items, change of eo and labour fee. oh, cos i failed to check my eo reguarly. didnt know it it would eat my up my eo. so was happily riding back from kallang, then jam at amk ave 3 exit there. so you should check your eo reguarly!

@dgray ahahaha, i thot so too. but now have to regularly check eo ah. any proper way to check? after or before ride?

Few yrs back my piston jam due to ignorance. Hardly check my EO level. After overhaul n a hole in my pocket, every 3 days i check. Hehe...
