Seen this before - thanks for putting it here.

The air flow path won't be as good as stock - but when you don't have any other options, you make do. . . .

COST: I have seen these HOSES sell for 20-35 dollars per hose at a hose supply [ commercial ] shop in my town.  So do you buy two and cut in half to make the bends ?  I use Mr. Weeks fix of the CB750F boots and mounted my XJ750R SECA carbs on my 750A HONDAMATIC race bike and with these CV carbs and reversed cone muffler spun up on my home made dyno = power.............  I have many sets [ 26,28,29,31,33,38's of carbs but none worked better with stock jets than the YAMAHA 750 SECA on this hard to mount [ 4 INLINE ] carbs on the  HONDAMATIC 750A.
For 6 months I tried every combination of hoses, boots and carbs and could not get a idle or top end that was good !!!!!!!  Thanks to MR. HONDAMATIC for the tip on CV carbs and stall on auto transmisson = you think I would have known that from my CM400A HONDAMATIC [ CV CARBS ] drag bike that I have went many rounds on over the past few years ??

I have a '77 CB750A with dry rotted and cracked carb insulators and am looking for a solution. How are these working out for you? Any issues so far? Thanks.

Has anyone else tried this? At 69.03 msrp for one hose that's a expensive trial and error for me

Hello
These diy carb insulators is workin well on three Matics. Two with sidecar and one solo.
If you can´t get better then these are good enough
