carb jetting...
ano ba motor mo sir?automatic o handclutch,,,magkaiba kasi ng main jet yung dalawa eh,,,yung sa hc size 103,,,yung automatic size 105...
kung stock engine ka pa naman tapos handclutch pa,,try mo palitan ang main
jet mo ng size 105...kung automatic nman ok na yun,,,
kung naka big bore ka,, try mo palitan ang pilot jet chaka main jet...eto ipalit mo na size...
pilot jet = 22.5
main jet = 110
yung pihitan ng hangin nasa left side,,,yung sa idle naman sa right side,,,
kapag naka full open carbs ka,,,try mo isarado yung hangin tapos buksan mo uli ng 1 1/2 na ikot...kapag naman naka airbox ka parin pero walang filter sa loob,,,try mo 2 ikot,,,kapag naman binalik mo lahat yung airbox and filter sa loob,,,gawin mo 3 ikot...uki na?

Re: carb jetting...
paps, diba sa 4stroke carb walang air screw, fuel screw lang, sa 2 stroke yung may air at fuel screw? kasi kung buksan mo todo yung air screw man yun, lean na fuel mix mo at alam mo na kung ano angyari kung lean, sira sparkplug mo at worse, mabutas pa piston mo dyan...correct me if im wrong paps...dowaldz said:ano ba motor mo sir?automatic o handclutch,,,magkaiba kasi ng main jet yung dalawa eh,,,yung sa hc size 103,,,yung automatic size 105...

sir if your using an air filter if yung oem ng yamaha, you can set it at factory setting at 1 5/8 turns out but for optimum settings, turn it 2- 2 1/4 turns out but it varies on each bike, just first turn it 2 turns out and work your way at 1/8 turns out per interval, after each 1/8 turns out, test ride your bike bcoz sound alone is not enuf...hope its of help

look at the notch on the left side on your bikes cover the one thats covering the carbs, some have a rubber flap, with a flat screw driver and a flash light, you will see 2 screws on the side of the carb, the one on the right is the idle screw and on the left is the fuel screw, with the bike warmed up, turn it off then turn the fuel screw in(or close it clockwise) then from the closed position, turn it 2 turns OUT or counterclockwise then test ride it and work it 1/8 turns out until you get the best ride possible..
ride safe
