DK External breather bolts
Hey all,
Recently installed a new intake, DK Hi-Flo 425 with external breather bolts. Installed them the way the instructions explained with no problems. I DID NOT use the washers because I didn't have a gap where the plate meets the breather holes on the top end. I did use blue loc-tite on the breather bolts.
Problem: After riding for a little today, I noticed oil making a mess all over the place on my bike! I understand that maybe a little here and there may blow out but this seemed to be a little excessive and annoying.
Any thoughts? Should I try thread sealant instead?

Where is the mess....dripping from the bolt or oily mist over the AC?
Sound like blow-by if its all over the place....first thing is to check your oil level...should be around mid point between full and add lines. Blow-by can be caused by overfilling.
If it is dripping from the mounts, then it is probably not seated properly...use washer between mount and bolt.
Otherwise use double filter in the EB bolts to minimize oily mist...this is what I did with my external breather bolts.

A catch-can IMO is the best option if it suits your AC and look. Depending on what AC U run, I change the EBS to what best works with that system. I currently run an Arlen Ness Deep Cut AC and run the filter option since it is completely hidden. A catch can would stick out beyond the AC and visible.

The filter doesnt get soaked and drip at all?

Haven't seen any oil drip out of the filter yet...and I clean my bike often so would have noticed it. I used to see oil mist on my Outlaw 587 but it was so light that I just wipe it off...I also only had single filter at that time. Double filter was recommended by Kevin at DK....asked them to install it before shipping. They are so awsome.

If you are still having issues, use a nylon washer between the mount and washer since they seal imperfections in the metal (i.e. your brace). Also be sure to clean your mounting surface on the cylinder.
