Just confirming catch can vent lines needed.

Postby bark615 » Thu Jan 17, 2013 11:48 am

The bike in question is stock class CRF100.

I would need 3 lines going to the catch can correct? (per the rule book)
1. Carb vent tube
2. Carb float bowl drain line
3. Fuel tank vent line.

Will I need an additional vent line coming off the canister to prevent an air lock? or will there be free air vented through the carb vent line?

I will need to get a 1/8" barb fitting for the float bowl drain line.

Fuel tank vent does not need to go to can of you get a nifty one way check valve for the line. Also your can will need to be vented to the atmosphere so it will work properly. I just run 3-4 ft hose up under the seat on top of the air box

Put it on the box; or on the crash truck!

You mean one of these things? Motorcycle Superstore has them for $12, not sure if they are any better than the eBay ones for $8??

Correct! The eBay ones work the same. I have them on all my bikes
