What's the bore and stroke size of std LC engine?
Added on August 3, 2009, 7:27 pmOk, found it... 54 x 58.7.
Hmmm, you guys upgrade it to 60mm bore.
I was just thinking, changing to bigger piston/block, are you guys still using stock head, or there is one matching the new block?
If no change head, I guess that's why some of you are hearing 'weird' sounds from the engine, especially if skim block and racing gasket some more...
I am currently using the 60mm kit with S6 racing cam. and previously, I also use 22/19 head. This head is kicking good, but eventually the timing chain tensioner spring was broken, it damages my cam bearing (all the ball bearing come out), then 1 of 4 of the valve broke which causes a hole in the piston face and also damages the head chamber. a modified head (22/19) will cost around RM600. if you really want to change, please keep your original head in all good condition. you may want to use them back later...

I think the weird sound you're talking about is coming from either the valve tappet, or the head knocking. just bring to the shop and ask for TOP HEAD service and see if that works. it has works for most of my friend.

lol, you remove the end cover along with the silencer inside?
hows the sound? last time my friend also did like this,
and the sound is foookinggg loud, same par as AHM one I think

umm... I think from that picture.... isn't that an ABM Exhaust without the Silencer ?
this pipe is quite good if you know how to set the carb to match it... some friends are using this too..

tq.. i'm from salak tinggi.. biggrin.gif how bout u?
how's the block? does it cause the engine to be louder or produce any awkward sound?
how much did u bought for urself?
I'm from KL, and work in Cyberjaya, so Salak Tinggi is not that far from my working area... and I have a friend who lives there too..
the Block set that I bought is okay, it fits right in, but here, we do a little modifications to the coolant flow so that the coolant will recycle through the block and the radiator. I'll show you guys some pictures when I have a chance to snap them later.

its really a simple mods but good for big bores and long distance traveller like me.

I bought the block set for RM125.00 not including the coolant mods.

well... it the block did not make any weird sounds, its very quiet. and that really depends on who installs it and is it installed properly.
