No argument too; jetting involves atleast Rs 200, fiddling with needle is FREE. Its one's choice whether to explore FREE options & then spend or viceversa!!! I speak my own experienceSkill is what keeps you on a Motorcycle

Which flatslide are you using? If using a "TM28 Smoothbore" then the stock jets come with 15 pilot jet and 180 main jet. Will recommend upgrading the pilot jet to 20.Originally posted by jd666 View PostONLY GOD WILL JUDGE ME

Any suggestions???

If I'm not wrong, your plug should show a jet black color; put your needle one step above or rather in middle. You'll need to fiddle with airscrew (allow less air) when you make this adjustment. Incase, your plug is not in jet black color, pls let me know.Originally posted by jd666 View PostSkill is what keeps you on a Motorcycle

JD, i have gone through the Pics of Cylinder kit as well as the Con-Rod assembly in detail. I am afraid, these are not the original ones. The RX-K OE Cylinder has '4Y201' marking on it & even the Con-Rod should have '4Y2' marking on one side & 'YAMAHA' on other side, else it is something else.Originally posted by jd666 View Post
I remember "sunnyboi", had previously confirmed this in this very forum. I have even checked with my Tuner who has been importing these things for quite some time now & he too has a similar opinion.
I would leave this matter to other seniors who have the exp with RX-K parts.Comment

Guys, have a question on carb
1. What would be venturi size difference between 100, 135 4S & 5S?
2. Can I simply take a 100's carb, plonk the 165 MJ & 17.5 PJ & fit it directly on a 4S? Like wise, can I take the appropriate jets for 100 or 135 5S & get them fixed across?
Any input is appreciated.Skill is what keeps you on a Motorcycle
