    Hi all, anyone care to share what have you guys done to the engine this far? Seemed like the majority are cosmetic modifications so far.

    Anyway, great site! And keep it going!!!~ Cheers all!!~

    i guess changed of CDI.
    there are available racing cams already in the market.

    also change if spark plug from the stock spark plug to iridium based.
    High tension wire change.

    im just wondering if someone already did some port and polish or porting in their t135 engine :)

    well some friends at Indonesia found iridium NGK sparkplug to replace the stock CPR8EA9... with same heat range and sparkplug length.. If I'm not mistaken, the code is NGK Iridium CRX8-EIX

    Msia also have ppl claimed that a certain type of spark plug works as well. Not too sure about this. Didn't dare to try. IMHO, the stock is good enuff. The race bikes in my team runs stock plugs. Just gap it properly will do.

    Is its close enough, you might be able to get away with it... But in all honesty, I think there're much better modifications to be toying around with as opposed to playing around with spark plugs... :p

    Hi bro, next year, the cubprix expert category in msia is gonna be big-bored (150cc) 135LC right? Do you have the slightest clue who is supplying all those kits for the racers? HLY? Or some other aftermarket makers ie TDR? Or the workshop/ racers themselves?

    Cheers.

    Well I read on local magazine that here in Indonesia, there's a guy who succeded to bore to 300cc, looks like he put some addition to cylinder, but closing the water jacket (back to air cooled).. but not so sure whether the compression still like the original one.

    300CC??!! *gurlp*** I'm sure either the bike is for show only or it can only last 1/4mile a go.

    Cheers!~

    Any bore-up kits, cams, big valve heads etc reached your shores yet? I know Mitra2000 just brought in some big valves TDR heads... BTW, TDR is very pricey over at your end right?

    Nope. Sleeved items. The piston looks forged, but should be cast. Don't think a sleeved cylinder can withstand a forged piston.... :shock:

    ?? Well so if you must buy a pair one, sleeved cylinder and a cast piston... but what good it be if we get more displacement, but we lose the others... well life is a matter of choices :D

    Like some guys here, they modify in extreme way, until parts that Yamaha brand maybe only 10%-25% only... why they don't make custom bike from beginning :D

    I installed Kitti E1 cam, done some head works (port and polished), Kitti X box CDI (TPS no longer working when installed), Kitti big bore block 58.mm kit (with dome piston) and 28mm keihin flat side carb.

    Now displacement is 155.7cc

    Excellent modifications!~ How is the result? Strangely enough though.. When I visited Mr Kitti Pak Nam, I wasn't told that he had big bore kit.. X-Box and cam yes.

    Oh yeah, the PWK28 you're using is good!

    So how's the result like? Is it much more powerful now? BTW, did you stroke the crank? And big valves installed? The Kitti E-1 cam's duration is? You've got any idea?

    You didn't mention that you've got any race pipes on or not. I think you better get one fixed now if you haven't! Cos the stock catalyzer pipe's sure gonna be restricting sh!tloads of power now!

    Cheers. Nice.

    The Kitti E1 as we call it locally a stage1, dont have the idea as to the overlap duration, but its mild with about 0.95mm lift as against stock. E3 is more radical.

    As for the pipe I'm using DBS.

    I did not stroked the crank, the stock stroke of 58++ for me is enough, the bore x ratio is now square, others here is aiming for oversquare to up the RPM like using 65mm bore using sleeve and different piston.

    Still stock valves, hard to find big valves here for multi valves, lots of valves for two valve heads.

    As for the power, could easily hit 100++ in a burst, smoked several modified motorcycles ranging from 125 to 150cc.
