Hey guys i have a 78' 1275,

And my hose between the crank house breather and the Y connector to the Carb and Clutch breather has worn out n split on me today

i have ordered a new hose but in the meantime should i be driving it?

Also i have seen a few engines with a tiny air filter on the breather, could i just replace all hoses with two filters on each breather (what size 12mm or 15mm?) ?

if not what is the purpose of them like whats it let breath and what does the hoses do to the carb?

 

Many Thanks

The breathers reduce crankcase/ gearbox pressure build up.. By conectone them to the carb, the engine burns any oil which is expelled by the engine

If you are driving it, I would say tape up the split pipe, or block off the breather pipe on the carb. But definitely do plumb them in.

Yes the best TEMPORARY fix is to tape the Y piece up

When i say split i mean completely snapped and it sits on the manifold inlet so im worried tape it up with the heat, so untill the new pipe comes your saying block/take off the hose to the carb?

My pipe had split where yours split too.

 

I just spliced the two ends back together with a piece of copper pipe we had lying around, hose clamp either end.  Been fine ever since sitting down in that gap between manifold and rocker cover.
