  1. I read all the author's data on motorcycle oil. I agree Shell Rotella T Synthetic is hard to beat... best thing it's $8/gallon at Wal-Mart. BUT IF you believe everything the author wrote about... he'd have you disconnecting your automotive airbags too! So don't believe everything you read about. It's more important to change your oil and filter often... no matter what brand you use. Discussing oil products is like arguing which was the best NFL team of all-time. Which we all know was the '72 Dolphins!!!
  2. I've read lots of threads about this problem and decided to replace the o-ring on the needle valve. I recently rejetted the carb and noticed the needle seat o-ring was in bad condition. After rejetting, the bike ran perfect for about 2 weeks and then gas starting leaking. The o-ring is discontinued by Suzuki, so I went to Home Depot and matched it up best I could. The old o-ring had shrunk to a point where it wasn't sealing anymore. I had gas leaking into my intake manifold and draining out of the bike when parked. When I installed the new needle seat o-ring, I had to press the seat back into the carb with lots of force. After reassembly, the gas leaking problem was worse. Question #1: Does the needle seat need to be move up and down? Or should it stay in place? I figure the o-ring I used is either too big or the needle valve is not sealing and needs to be replaced. Question #2: What is the root cause for gas leaking into the intake manifold? Leakage at the needle valve or seat? Any help you can provide will be appreciated. Thanks
