I dont think traxxas is disrespecting our language, he just wants to know the meaning of BOBOK.

The term not smooth doesnt really suit its meaning. Even when your wheel or brake caliper jammed, you will feel the bike not smooth.
Try choking the carb and you will get the term bobok(either the carb is too rich or lean) :lol:

Is there really a reedvalve in this 4stroke bike???? Ive been owning and tuning 2stroke bikes since 1996 and this is the first 4 stroke bike I own, and probably wont tune it to the max. I tuned a couple of 4strokes before but never these 135.

ok guys found the problem...the thing i hab modified to my bike is racing pipe,racing valve spring and camshaft,racing cdi, and change of the pilot jetting..

the problem cause the unsmooth feeling is due to the camshaft.i could not use the hi camshaft as my block and piston could not support that much power.As there is alot of camshaft.my mech try to find me other racing camshaft which is good enough to support the power.The racing bee camshaft need more power to run smoothly as i dindt change my block and piston to the racing ones so have to use other racing camshaft that is not as good.

now im happy with bike.can run at expressway smoothly and 4th gear go 120 with a little open of throttle.

hi.. i want to ask sumthing.. i've change my block to 60mm and also use yoshi hi-cam, but what i'm wondering is why is the mechanic grind the surface of the piston and what i can see is he's making a big hole overthere.. i know the reason is to protect valve from hitting piston bcoz of hi-cam/racing cam, but does doing this will effect the power..bla..bla..etc??

guys just a head up. if you are going to change cams make sure you change the valve spring.. one of my friend try to change cams but not the valve spring. the result all his 4stock valve spring broke at high rpm... and im just wondering? could this really happen or theres a mistake on the setting? guys need your opinion on this matter.. thanks>>>

In my experience, I just changed the CDI to rextor, exhaust to 4N pipe, coil to daytona, block to vixion and cams to vixion camshaft. The rest is stock. With CORRECT INSTALLATION AND PROPER TUNING, you can increase the power for about 40-50 percent. Changing valve spring and cams would not make a big difference because your block is still stock.
