40mm intakes

[crassius]

Been using motors with 40mm intakes for a while now. Have them with aluminum intakes, but ordered some steel ones for spares. I'm finding that on a tight frame build, the carb often won't fit in the frame.

I've found some steel intakes that give about an inch of extra room when needed.

ON left side in pic below.

Where did you get the intakes?

got them from BGF, but he looked thru his shelves and has no more of the short ones : (

may take a while to find someone that still has them

I also found some cast aluminum that appear to be short. Make that rough cast...

Of course, you could always go dual carbs.

steel onesnot same - says 32mm right on the ad

aluminum ones appear to be the long ones that come with the motors

the short, steel 40mm ones have a small round opening at the mounting point
