intake outlet diameter? for DIY intake mod

Anybody know the diameter of the intake port on the Z125? I have a few silicon hoses running from 1inch to 3inch around the house was thinking about just clamping one of those on with a K&N intake filter or so.

I was also curious about this. Just dont logically see paying $100+ for a little k&n breather filter and a piece of tube. If no ones knows off the top of their head, i will take it apart this week and check it out.

I AGREE, THESE INTAKES ARE WAY OVER PRICED. A CHEAP SILICONE TUBE AND A BREATHER FILTER THAT WOULD SIT ON TOP OF A VALVE COVER, ILL DO MY OWN AND BETTER! STEADY GARAGE SELLS AN OVER SIZED THROTTLE BODY ASSEMBLY. IT SAYS ITS 26MM, I FIGURED ITS ABOUT 1 INCH

your about right just went to the site and looked up that throttle body and it states "OEM stock size is 24mm, Chimera is 26mm! ALL OEM Sensors are intact". I will double check just incase.

Looks like the Dayco C71289 radiator hose will fit it has a inside diameter of 1.34" and already has a bend so all you need to do is cut it accordingly. Same hoses as a lot of the Grom guys are using to Mod their airbox.

To add on the Dayco hose has a 40mm outside diameter so check out the K&N RC-2314. It is nearly identical to the one that goes on the chimera intake with the exception of its Flange inside diameter of 40mm vs the 50mm that the chimera uses. This will fit the dayco if anyone is having a hard time finding a hose..

No need to replace the hose just break the glue around the original hose that attaches to the air box. Pull the hose out of the air box and you will notice it has a lip on the end which is perfect then go buy a filter with I think a 2 inch diameter make sure the lip slides in the filter and whalaa.

Thanks for that!! I just order the air filter! I run that exact filter on my dirt bike lol.. Once it comes in i'll be dismantling the air box!

The air filter is By "Uni", just ebay "50mm uni air filter" and a schwack of them will come up and for around $20. Great air filter and i ran mine on my dirt bike for a year now, you just need to pre oil them before installing.
