CV Carburettor Electric Heating Kits

[koko64]

Having rejected the messy plumbing of the oil heater kits I have been looking into the electric kits. I note that Ducati have used small elements on the body of the carbs in line with the carb mouth. Triumph on the other hand have the elements under the carbs at the back of the float bowls. IIRC someone here commented that the Ducati elements are very low watt units.  I have found some KTM units at a reasonable price too (not sure of their rating). I have two Ducati elements spare.

Have people found the electric heaters effective? A mate in electronics will be consulted when he returns to Australia and we may build a kit that warms the bowls and/or the carb mouth/throat. I figure that the use of DOT 15W LED H4 headlight globes leaves some margin to pull 40 W total out of the system shared between the carbs. Is this a reasonable assumption?Would a single 20W element per carb work or two 10W elements per carb and what would be the best location? The float bowls have threaded holes as do the carb bodies.

Any thoughts or suggestions would be appreciated.

That person might have been me.  IIRC, 3 watts maybe.

G'day Howie

So they don't heat up enough to make a difference?

Any thoughts on heating the fuel in the bowl Vs the carb throat area?

Be interesting to see how 20W elements warm the bowls and how much heat is transferred to the fuel. Then there's the safe level to not exceed I guess. Mind you, carbs get pretty hot in summer.

An old problem.

Yeah, reread the whole thread.  Brought back memories.  Ideal would be to warm the air going into the throttle bodies, but how?  Therefore, heat some part of the carb body and hope.

A few threads came up for sure. Good memories.
Back in the day, I had a 93 FXR that suffered on a misty Friday night. A Mikuni 40mm flatslide changed my world.

 After a few drinks, my electronics mate will design a kit.

I'll find out more about the Triumph oem kits. They're English, surely they know how to stop carb icing.
My electronics mate is also an avid small plane pilot. He belongs to a club that flies old birds, so should have ideas about how to prevent carb icing.

Might help, but won't solve the moisture in the air problem.

True. I have outer filter bags on the pods and some one suggested that the covers being water repellent might help.  Maybe in wet or misty conditions. I guess ill find out.
