same hir.. but not 10mins.. i think 20-30secs..
 
How come,,maybe its not in the ring,,because my block is new,,I change my stock to Vixion.....maybe its on the carb side,,still experimenting on the jet's size....tnx......:rolleyes:

Papz it could be a valve seal or Piston Ring problem just like papa sagad of SCOT, Waswas mode and a smoky pipe. Better let a yamaha 3's mechanic check it for you.

based in my experience, try to change first the gasket cylinder baka tumatagas na ang coolant mo kaya may usok at hard to start the engine!!

hehehe paps english speaking thread...check the spark plug if it is black and wet..it's not on the turn...the settings for your af mixture will depend on your sparkplug's burn result...it happened recently to my monster bike,they checked the head and block and rings,only to find out that it was the pipe because it's wet with oil...grrrrrrrrrrr

asking ur help with this problem on smoke.
set up:
keihin 24mm carb
changed valve seal
newly changed 60mm bore kit
back to stock pipe (previously used nob1 and dbs pipes)

until now, there is still white smoke coming out. what is possibly the cause of this and how can it be solved? tnx a lot in advance for ur comments.

sir, gud day..

advise ko po is iparebore nyo ulit yung block sa masmaayos na machine shop, based on my experience nung newly rebore ung block ko nauusok din, papalit palit pa kami ng ring at halos maulol sa kakaisip kung bkt nagsusunog ng langis,. yun pla tabingi yung pagkabore, binalik namin yung old block tapos nawala yung problem ok na ulit...
