Are the needles not aluminum? They always were on my 2-strokes (RZ's and RD's).
Steve, did you change them, or do something to them when you had my carbs 15 or so months back?
Not asking you to remember my carbs specifically, but what happens with the full $300 service?
Bike runs like a million bucks, btw!
Todd - the 300.00 service is disassembly, polishing the seats, cleaning (I use an ultrasonic tank now) inspection of all parts, reassembly, installing the 2 minute jet kit, installing overflow tubes, Setting fuel float height then filling and checking / setting fuel level, providing the drain tube system, and shipping back. If the carbs need extra parts, IE needles or orings there's an additional charge of up to 72.00. If your carbs were 300.00 you didn't need the extra parts.
I do use aftermarket stainless steel needles. The stock aluminum needles will corrode from water, and ethanol / additives can also attack them. Additionally, the needles I'm using have higher spring seat pressure, so they control fuel level better. HTH, Steve
