I want to add a sight tube to my 650. I have the scotts stabilizer which fits into the dip stick hole and need to take the stabilizer off everytime I want to check my oil level. Does anyone have any experience installing a sight tube? I have already checked out the Yahoo page on how to do it but, I'm a little bit nervous about drilling into my frame. How do you prevent any of the medal shavings from falling inside the frame? Any suggestions or hints would be appreciated.
