Catch can

[jcd]

1986 1100 slabby. 

36mm flatslides.  do they need a catch can? 

i had the top breather hose running to a filter but it soon cloged up then had it above the chain but was getting oil driping,  i have it runing into a plastic bottle now with a filter on top,  but thinking maby a catch can would be better?  but do you have the outlet running to the carbs?  and how?

Is there oil coming out of the breather? If yes, you need a catch can, If not, you don't

hi, yes oil does come out of the breather.  I would like to put a catch can on it , so breather hose goes into the catch can but I don’t  know where the the output hose from the catch can would go since there no air box to go into

Depending what you use for a catch tank. You can just leave the top of it open to let all the vapours evaporate. It'll fill with oily goo, that needs emptied from time to time. Yonks ago I used an old drinking bottle for catch can.

I have an aluminium shampoo bottle on mine !!!!  polished all the logo shit off first  the tube from the engine fits tight in the top but i drilled a few small holes round the top so it can breath.

A Budweiser (or similar beer varieties) can used to be std. fitment at the Bulldog Bash - no catch can, no racing! Not that they were hard to find ! Wedged into a gap or held with a single zip tie - them were the days!

If your catch can works alright you can vent it into the air..
