all speedometer read high, approx. 5~10% (+) higher.

the higher speed, the more error.

 

u want to know wat's the actual speed.

buy one of those bicycle digital speedometer, like sigma.

u have to measure the circumference of front tire n input to the meter.

it has an error of approx. 0.5~1% but after some tire wear will increase to >2% need to re-calibrate again.

 

y only sigma speedo ?? can use other like ( cateyes )

I did 140 with custom legal exhaust.. No overheat no powerloss no other mods, stock airbox, stock cable, all stock.. Only exhaust.. Oh and before that my bike happily 120 all stock..

[crazydj]

Oh and before that my bike happily 120 all stock..

 

Haha? Seriously?

Poor him then...

[yinghai]

Yeap.. I myself wonder how those ybr in other countries can hit 130 no problem.. Maybe his bike old.. I myself own two ybr fz and fba plate.. Can only do 130 downhill.. If not it will just stuck at 120..

[yinghai]

Haha? Seriously?

He can have the world's best air filter installed.. The best aftermarket cdi with the best ignition curve.. The best cables... The lightest sprocket, the smoothest o ring chain.. All this on a restrictive exhaust?, he wont go anywhere... Anyway, making a hole in the exhaust wont unleash its full potential.. And becareful with those aftermarket cdi.. Ive seen alot of cdi that doesnt make any difference with stock ones..

Where do you get the legal exhaust for YBR? Which brand and how much is it?

[yinghai]

I mod the exhaust bro, Cut open removed a number of plates and stuff fibre in it.. Finally put a long straight preforated tube or silencer in it.. The exhaust tip remains the same to give you the low end power.. The straight through silencer give you the top end.. No jetting has been done. Airfilter modded with foam filter for easy washing.. No other mods.. Went inspection once only with the exhaust.. Passed... Sold the bike before i could test the second inspection. Did the same to my rvf.. Passed one inspection.. It can be considered street legal since i pass the inspection..

[Limhg]

Its what people call tong pipe? You went to JB to do? I want more top end power for it. Always cruise at 80 at expressways, worried to cross the 7k rpm mark. Engine struggling. How much to get it done?

I do it in sg about 150 bucks.. Malaysia should be cheap.. Just make sure you get a good fibre and the exhaust tip stay the same.. Cheap one will wear out fast.. I always cruise about 100-110 at about 8rpm..

[Limhg]

Oh! Tell me where to get it done in sg! its so hard on the engine with the restricted exhaust. And how do you remove the rust on our exhaust. The china made metal rust super crazy. It'll be cool to have a ride session with all the YBRs. Is that a Cagiva Mito in your picture?

You can try calling Hong Leong again ah. When i called, it just arrived in Singapore and i called them straight away. Perhaps you can try calling them again and help us check how much its costs also and the break down?

[fufu]
