QUOTE(piju @ May 15 2014, 10:32 AM) i see, thanks for the info. If you think is high RPM, then perhaps need to kacau needle. Before you do that, try with pilot screw open and close quarter turn extra from default 3.5 turns.just now i set my fuel screw to 3.5 turns and added 2~3 minutes more. idle RPM quite good. throttle respons also good. but when i ride the bike and feel like some bog and hesitant happened when the bike is high RPM on gear 2, after i shift it to gear 3 then it's ok. is this happen because im using high flow air filter? (i assume than when higher rpm, the combustion chamber will produce more pressure to suck the air and since im using high flow air filter, the air will enter more than fuel, this is why bog and hesitant happened) At different throttle opening, the AF ratio changes. So, after air filter change, you need to readjust the whole carb circuits... not just pilot screw. |

Since naik harga, more reasons not to use Michelin liao.
My RGV fuelly:  2T around 1L per 1000km, RM20 each botol. |

QUOTE(piju @ May 17 2014, 06:28 PM) alexei I think someone mentioned BS25 carb needs some restriction at the intake, with the high flow air filter, quite a lot needs to be done.i think i know what is the biggest problem tuning mikuni bs25 carburetor. it is because of the low restriction air filter. i think i solved the problem by reinstall the stock paper air filter and retune the fuel screw until i hear maximum RPM. if i still want to use the low restriction air filter, i think i need to rejetting the carburetor to compensate the air. as i know, the perfect combustion will need 14.7 air and 1 fuel. means 14.7:1. if we allow more air to enter the combustion chamber, then we need to allow more fuel by rejetting the carburetor. this is critical on higher RPM but not critical on idle and low RPM. if we allow more air and more fuel, means we are dropping the fuel efficiency. we still dont know either the combustion chamber can handle the burning or not. if it can handle, then we will get more power. if it dont, means no perfect combustion then we will have fuel efficiency drop and the side effect is our piston maybe dirtier than before. am i right bro alexei ? Basically, without the intake restriction, the carb would lose the required vacuum to open. That means, it will never reach max throttle opening. To rejet, is critical for all rev range, not just high RPM.  In real case, for the same engine, improved air flow will produce more power and smoothen torque curve. It is about making it easier to drive, and when that happens, sometimes it actually improves FC. About the carbon deposit, I think it is inevitable. |

pijuIf use high flow filter on BS25 carb, it actually 'restricts' the throttle. So, it doesn't improve performance. Unless if the engine is modified to demand more air through the carb, then perhaps it can make a difference.
Honestly, I haven't tuned a BS25 carb before, so I can't say a lot about it. This post has been edited by alexei: May 18 2014, 05:07 PM |

QUOTE(NewGUY @ May 18 2014, 02:32 AM) So means every tank of fuel is 4.6 liters + about 250ml right? My fuelly includes highway, so a bit too good for city riding.u getting 250km per tank? how much per km? mine around 0.065 sen per km i just 1 to know the difference.... Bcos a lot of ppl say untune 4T compare to untune 2T, have 50% saving in petrol and 2T.... Petrol: RM9.6 for 170~180km, 5.5 sen per km. 2T: RM20/1000km, 2 sen per km. Mine petrol + 2T total is 7.5 sen per km. Yours at 3.0L/100km, is about 6.3 sen per km. This post has been edited by alexei: May 18 2014, 05:14 PM |

pijuHere are the steps, in short:
- warm up - set idle screw to high, RPM ~1.5k to 2k RPM. - set pilot screw to reach max RPM, open few more minutes. - set idle screw to normal, RPM ~1k, or engine is running smoothly. Check: - off-throttle performance: from idle, pulas the throttle fast and see if engine can follow or not - steady acceleration at fixed throttle opening - acceleration with continuous throttle opening If there is any engine bog or flat response, continue to replicate the condition, and check the plug to tell if rich or lean. Perform tuning, and check again. Until puas. In the end, your bike will have very low FC, good power across RPM and throttle opening. No semput-semput or misfire here and there, perfect. Then, if you upgrade parts, may need to go through the whole process again. If lucky, some minor tuning is enough. |

pijuI know it's 1 5/8 turn for the VM carb, not sure for BS carb. I'll need to look at its service manual to tell if that is true or not, which I don't have. Do you have its service manual, since you own one? IMO, factory setting is usually richer, so that the bikes produced are more likely to run smoothly.

QUOTE(NewGUY @ May 19 2014, 09:02 PM) But last time where got such option all sbk high FC and high maintenance.... Well, you have to look hard enough, and be more tolerating. Of course, if you can only consider new bikes, there isn't an option.Last time can afford also, all sbk like 100% overprice.... Kawa ER6n, Z800, R6 all below 20km per liter.... The CBR 500 2014 fc is even better than Kawa Z250 or Ninja 250.... Looks 250 cc is underpower for the chasis... FC of CBR500R is good, 250R is average for its CC, but they are similar around 50~60mpg. If I have the money to buy a brand new kapcai, I would rather get any other used bike. Imagine if at the time, you bought a 2nd hand ZZR250 at 7k. Even today, you can sell the bike at the same price. |

cahayamalamkuto protect your face is up to you. I've seen quite regularly people wear fullface while riding moped. more common these days, since it's affordable, budget models like MHR, LS2, Greyfosh etc. motocross helmet i tried before, with visor, made me pening, and wind resistance quite bad.

QUOTE(Mr.CoMoT @ Jun 1 2014, 02:40 PM) New user here.. LC135SS anything that i should not do to my new bike? Its really truth about the PANTANG things?? Currently maximum speed 80-90.. Never touch 100 yet..sked bcos still new..hmm Welcome to the ownership club.DiaSil block don't really pantang, but IMO it is more for other mechanical parts as well, like the crankshaft bearing, camshaft, etc... the pantang is more on engine load and RPM, not really speed.
