Fanzilla (Son of)

I am posting this to back up Lee's hard work and inspiration (not that he needs it). My past efforts to stop my bike from overheating have not been a waste of time or money but they have not been the solution.

For me Lee's mod is the solution with some small variations. Maybe it's the fact that i live in the driest state in the driest continent (it's friggin' hot) or pehaps it's the bike, or the fact that my city is a grid of traffic lights that can't be avoided. Whatever it's a pain...... 'till now.

I seriously doubt the new mv impellor would be significantly different from the Vesuvio upgrade i installed. We all know the problem is air-flow so the new impellors just delay the inevitable. Even with aluminium 'muzzy' fans and the impellor the bike would reach 112 and above with the dash flashing.

So.. this is for all who have similar probs in tough climates.

Pics. You can see the poor seal from fan blades to radiator element. I could fit my finger under it. This provides major leaking from the side making the fan really inefficient. Lee solved this by adding a metal band. I lowered the whole unit and added a rubber collar to seal the cowl against the radiator.

The new gap under the fan was just enough to get the rubber in.
Amazing to put my hand in front of the radiator and feel how these fans now suck. Before, the top fan was like an asthmatic coughing through a straw.

But wait there's more to come

Two electricians advised that i ditch the 15amp relay in preference for a 30amp. Still using a 15 amp fuse though on a separate lead from the Bat.
The relay i bought was cheap but not very waterproof or strong so opted for a bosch. All connections were soldered (even to the relay).

The overide switch was as lee's. Made it as hidden as pos and black with waterproof top to toggle.

here's the rubber seal under the fan cowl. Also the new fan in situ.

So this should be the end of it! Anyone with these probs.. there is a solution.

Thanks again to Lee for leading. This has really worked for me. I've tried to get the bike to oveheat and it just won't.

the hottest it got under stress was 102. Mostly it just gets to 100 and just sits on it.
Sensational!

A fully sic fully sorted 1078.

Very intersting and a stunning result. So enlighten me, wouldn't that have worked without the 30 Amp Relay and the additional switch ? What are these two things doing exactly to improve the situation ?

Nice job, but I wonder; couldn't that Bosch relay be moved somewhere else, since it blocks air flow a bit in current position?
