Mine is a rubber plugin type .Nothing secures it .A friend has a lcd temp type stick that requires a twist to allow it to be removed .Can't find one to fit mine .When I dog my bike ,I have actually had it push out .Motor has good compression,runs great and doesn't appear to have much blowby at all. Stock stick Seems like a PP design.If I can retro a screw in type side cover ,,,that would be cool .I think ,but am not sure 1999 tc touring has different size hole than later models .Thanks for input .Any ideas encouraged
Breeze3at it is engine oil stick
