You can adjust the 2T level by turning a knob thingy at the 2T pump ( like tightening a clutch at the level there) it is at the end of the throttle cable , got 2 end , one goes to the crab and the others goes to the 2T pump. works for me...
  Ah Bear is going to get veri busy , coz now NDP comming heheheheehe Lim Ah Bear am i correct?

  yah lah,bo bian lei,we always do this kind of shit job one lei.btw,the gasket is not always present one leh.thomie,dun teach ppl wrong stuff lei.anyway see the service manuals or strip the pipe yourself to see lah.got then put it back also nvm one,the gasket must change when it is broken only.

  well, me riding hexagon....every morning and after work start bike quite difficult. i dunno wats wrong....even after servicing oso same prob. is it becuz of spark plug prob or 2T prob?

  try the spark plugs first the the carb tunings,which ever is available loh,best to try another bikeshop too.maybe your shop not good at tuning auto bikes loh.

  however i do notice that my phantom150 does consume less petrol than other phantom150s. Most ppl's ones can only last til about 200km b4 turning reserve, mine can tahan until 230++km.
  But running abit leaner gd anot??
  
  n oso, wat do u mean by 'great tuning for great throttle response'? mi quite blur bout tis??
  
  as 4 the plug. me using a cold plug (DIP), oredi knew b4hand that cold plugs do not contribute to a easy startup but gd for full throttle n harsh riding conditions. hence, i tink gonna change to the cheapest one( hot plug ) next time round. Cos i wanna see the differences myself so next time i wil know wat i want....

  cheeers
  

  it means the bike response better to your trottle loh.ppl always say it as kin kui lah.

  hello everybody! i am back!pls keep posting your technical problems here and i try to solve them.all those bikers with experience also pls here mi maintain this topic,if not i will be very busy jus replying to the problems posted here. i am not too expert in the two wheels things and i hope ppl with better knowledge can help and teach mi as well. hope u guys are willing to help mi.thanks.

  Hi Bear ....
  got some questions ... me also experiencing some start up problems .... I must use choke to start up even on hot days. If I dun use choke, cannot start. And also start liao must warm up beforemoving else is really will die engine. Is this the same symptom for what you posted previously on fuel coaggulating on the chamber walls ? I know my 2T very big ... most mornings start up got a lot of white smoke .... How do I adjust the 2T pump ? My bike KRR ...
  
  You mentioned about good throttle response ... how do you adjust for better throttle response ?
  
  Thanks !

  Too much 2T can also be 1 of the reasons that cause ur bike to be difficult to start. And also because of the high ratio of 2T, ur engine will die easily when just start(cold) without warm up. But the white smoke should get lesser when ur engine warms up. Another thing bad about too much 2T is that ur engine tends to have carbon and deposits clogs faster.
  
  Adjust 2T, change to new plug may help.

  It's prefectly normal for a bike to require choke to start up in the morning. And it's always best to warm up the bike to let the engine oil lubricate all those moving components of the engine.
  
  For your bike, 2 strokes bikes are famous for piston jamming due to insufficient 2T in the combustion chamber. SO i would advise you that it'll be safer for you see more smoke than to see no smoke and a jammed piston coupled with a broken conrod
  
  lastl throttle response can be adjust from your fuel-air-ratio, and your 2T intake , and your jeting.
  however be warned that if you run too lean you may be putting your bike in danger of a piston jam if there isn't enough 2T lubrication

  Hi,bear...
  i got something to ask... y after i tighter the chain.. not long the chain turn unit very tigh.. what happen?? i did see the motor shop guy give the chain free play... what really happen?? is it chain wear and tear or what happen??
  
  thanks in advance

  Actually, you chain should not be very tight ... there should be some slack. I can't tell you how much slack as I dun have the figure on hand, so let the experts tell you that.
  
  I can tell you why though ... actually, when the bike is not loaded (not carrying any weight), the chain has some slack. But when you sit on your bike, you compress the suspension and the swing arm actually moves about it's pivot, as a result, tightening the chain.
  
  Furthermore, I think there is a chain tensioner in your gearbox or something. When you kick in your gear from Neutral, the tensioner will tension your chain making it even tighter. So you can imagine what happens if your chain is already very tight when not carrying any load; you'll stress the chain even further when you sit on your bike. And imagine what happens when you cross a hump heavily .... Your chain might break.
  
  The chain cannot be too tight, neither must it be too slack. When the chain is too slack, it probably jump some teeth on the sprockets, and wear out both chain and sprockets prematurely. Worse, the chain may even come away from the sproket and imagine what's going to happen after that ... think the chain will jam in the gearbox and ... you know lah ....
  
  That much said, you must realise however that over time, chains that were at correct tension will eventually gain more and more free play ... this is normal wear and tear. This is why you should tension your chain properly on a regular basis.

  hi,
  I understand that it might be risky to tune the 2T by myself. But I do not like the pollution from the white smoke and would like to minimise it as best as I can. There's got to be a way to tune the 2T requirement just rite ... So think I wanna risk it .... how do you adjust the 2T pump setting on a KRR ?
  
  I did try adjust thing my air-fuel ratio before ... but it didn't seem like it made a difference even after I made some dramatic adjustment .... Can someone tell me how to adjust that properly ?
  
  Thanks.

  Hi, I understand what u mean my chain is quite slack so i plan to go tightening the chain... i also understand about the free play.... now is after i tightening the chain the chain, i pillon my gf.. after i short ride the chain turn out very tight.. and even my bike put on side stand the chain still very tight... today i go losese the chain... but not long still same y?? what really happen???

  no it's not necessary to use the choke while starting in the mornings.
  
  before i had tuning problems and choked plugs, i was able to start my bike within 3 kicks in the morning without engine stall.
