Air Cleaner Advice
Hi all,
My Lowrider was fitted, when new, with a Kuryakyn Hypercharger and V&H Big Radius pipes. It was also remapped to Stage 1.
The Hypercharger isn't my thing, and I'd rather swap it out for a different look!
Any ideas which air cleaners would work as a straight swap, without me having to pay for a remap or invest in a controller?
Thanks in advance!
Chris.

Any aftermarket intake will flow all the air you need, no remap needed. As long as your changing it, you might want to consider one that has external breathing. Your motor will be happier with it. Among others, DK Customs has some versions that you may like.

Absolutely agree, love my 587 and venting crankcase gasses to atmosphere is the only way to go. As nevil said, several options are available to externally vent the hot, oily, oxygen depleted gas...

Venting to the atmosphere is the way to go. The one thing I don't understand is, some guys install rubber tubing from the breather bolts to a filter that they either hide, or install it where it looks like it belongs. Why the filter? The crankcase is under pressure and eventually the filter will get soaked with oil and drip. With the proper amount of oil in the crankcase (half way on the stick) and using just the breather bolts, there is very little to no oil blow-by or misting coming from the breather bolts. Nothing that you can't give a quick wipe every couple of weeks.

The filter is good for 5000 miles before it needs cleaning,, it doesn't "drip".

I used a horseshoe and a long drain line to vent the misting under the bike. The oil would drip out of the hose leaving quarter sized spots when she was parked; the oil was also splattering my rear tire while riding. I added a push on filter to the hose which allowed the air flow while riding to help evaporate the oil and keep it from getting on my rear tire.
I went with the under A/C filter when I removed the horseshoe breather and this seems even more effective. With shorter hoses the gasses don't seem to be condensing in the hose, they're being removed/exhausted faster and with good air flow the filter is showing no signs of oil contamination.
This is the cleanest setup I've used yet
Trask Mystfree breathers and enlarging the oil drain holes in the rocker plates are coming up next but for now this is working very effectively controlling the excessive carryover/venting of this Twin Cam.
