The possibilities are many..may be you should check ur engine oil level first..too much..back compression can retard your engine overall performance. What engine oil are you using and how much was put in. Use the inspection window on the right side of your gearbox. Starighten the bike on a level ground while engine is very cold. Oillevel should be at the upper 2nd marking. Check this first.

One of the possibilities..usually if one of the plug is shorted or excessively worn..you are actually running on 3 cyclinders rather than 4.and exhaust sound bubbly like. You can confirmed only after running up engine at least after 5 mins. After engine has heated up..touch the four header with a quick tap. If there is one that's not hot or running cooler than the rest..time to change your plugs.

Thanks you for your answer

Just a quick enq. This morning when riding my super4 vtec3 to work, everything seems ok but suddenly when moving off from traffic light, the acceleration seems very weird, as in it dun accelerate smoothly and when reach my office carpark, the engine just stalled. Den I smell a burning smell from my engine.

 

Den I try to start my bike, it manage to start but same thing, when I turn on my throttle, from rpm 1 to 5 it seems like it have difficulties and not smooth at all.

 

I check my oil tank and realise my petrol is damn empty, as in fuel really left that abit. Nearest petrol station is abt 1km away and I dunno if I can tong till there anot.

 

Sorry to ask, izit due to there is no fuel alr or something is wrong with my bike? My vtec3 is going 9yrs old alr..

 

thanks!!

you shld try to topup the moment it hits reserve tank when your meter shows it. for me i personally top up when it shows 1 bar left. although that one bar plus reserve definitely can last me another round around singapore.

yeah, I want make it a little different, make it not so mainstream in the road . sure I will upload pictures after done later. I still fit that Triumph triple street head lamp on my super four. for change with Koso odometer not so difficult as long you understand the wiring of your motorcycle, I believe you can do it .

for that RX2N odometer on here almost $200 US Dollar.

 

Thanks you for your info for that link, I will try contact them and for Bagster tank cover some store can't make a shipping to my country, if yes that shipping postage really high. maybe I need go to Singapore for looking them .

 

and for your curious, I forget let you know if mine not spec3 but super four 1998, really ugly when I got it, that way I totally changed that parts. some I have change is:

 

for engine, I have bore up till 650cc, for wheels, I use Yamaha R6 front and real with 6" inches for real rim and 2,5" inches for front rim and tire 160/55 for real and 120/55 for front tire. and like I said before I use upside down from R6 too. swing arm use from vtec including real body. for odomoter use KOSO RX2N, head lamp from Triumph Triple street 2012, exhaust I use Termignoni carbon. and during fit that head lamp, I still made custom side radiator cover too from fiber, wish that will finished soon.

 

actually, I want looking another super four too for built another style, that is cafe racer style, seem that really nice style in this time.

 

I doing that all because I love modified my motorcycle, built a dream motorcycle is really so excited . I think you understand it what I mean .

wow, lucky for you that your bike doesn't have to go through inspection like singapore does yearly. with all the modification i'm sure my bike will never pass the inspection. all your modification seems too high level for me haha i only make minor changes mostly cosmetics. recently just did a major brake caliper clean up haha.
