Hello. My Bridgestone is missing the air tube, so I want to make one. Can someone give me the dimensions for the air filter intake tube (the chrome one) for a bs90 oil injected? I need the length and the circumference. It would be much appreciated.

Hershey, 90's have different size air tubes for premix, oil injected and sport models. These are the dimensions for 90 Sport oil injected and 90 Trail premix. I think there is one more? Hope this helps, Steve
90 Sport oil injected (all oil injected 90 models):
inside diameter 42.4mm/ outside diameter 45.2mm/ length 90.5mm
90 Trail premix (standard, mountain premix):
inside diameter 35.6mm/ outside diameter 38.0mm/ length 105.3mm

I have a bridgestone 90 trail, oil injected. Is that different than the trail premix?
EDIT: Nevermind, I see that your post says that "all 90 oil injected models are the same as sport 90 oil injected" sorry I didn't see that the first time.
Thank You

Hershey, All oil injected 90 models use the same air tube. You can down load a parts manual from this site under manuals from menu. Sorry about the confusion. Steve
