2011 Royal Enfield Bullet UCE 350 Air filter juggad

The air filter compartment of UCE 350 bullets were badly designed. The reason for this is that the UCEs had paper type air filter element and for some reason, the design was in such a way that the hole through which air was sucked into the air filter compartment was placed right above the air filter element, resulting in the filter getting soaking wet during ride in the rains. This in turn caused misfires.

The remedy for this is actually very simple.
Buy a radiator hose (bend type), the one for the Ambassador car suits well.

Apply silicone sealant on the hose and insert it like in the below pictures

What this does is that the water that gets sucked in during rain falls on the corner of the air filter box and gets drained through the drain hole at the bottom. The result is that the paper air filter element stays dry.

I have been using this juggad for over 7 years and rode my bullet to Ladakh and back, with good results.

Good idea.

Is the water getting in from the rear wheel or elsewhere? This is the same set up on my 2002 Bullet Electra, but I haven't experienced water getting inside the box till date. There is an inner mud guard for the rear wheel too which prevents this and is smaller in size compared to the later models.

Simply change your system to the old style chrome air box and free up you right side tool box.

Cheers, Doc
