Engine cooling?
#1
#3
These bigger inch Twin Cam's run too hot for their own good and improving engine cooling isn't a single magic bullet, but rather a step by step methodical approach involving great tuning, free flowing exhausts, free flowing A/C's venting hot crankcase gasses back to atmosphere, oil coolers, permanent oil filters for increased oil flow rates and lower parasitic load, relocating the oil filter, a tank lift providing added air flow to the heads, coil relocations to improve air flow to the rear cylinder, Wards fans, and cam changes to remove the 'EPA' cams. Each brings cooling to the table and it's a layering application of some or most of these modifications that will lower engine temperatures.
I've done all of these except fans and a coil relocation; my engine temperatures are much lower now, compared to stock.

The sad thing about Harley is you have spend an extra 1,500.00 to get these things to run right.
Gut the catalytic convertor in the head pipe it. All the cat does is generate excessive heat!
I gutted the cat out of the stock pipe & added a Andrews 48 cam & a Power Vision tuner from Fuel Moto.
The bike runs a lot cooler now. The cam helps the engine breath better & the extra fuel makes a world of difference.
