Harley Davidson M8 Blowby Solution - Clean up your motor's performance with a Feuling dipstick

[@Crush219]

So I was 37 years old when I realized that your Marshall mini stack was actually a beer fridge! P.S. love the videos. You and Mrs Monkey are awesome! Keep it up!

[@marvinr5054]

I'm glad you made this video. I did the fueling kit on both of my TC-95's and today on my new Ultra limited I tried a new tranny cover from a company called CNCNICE and I was surprise to see that it was very good quality. Cheap fix! when you look it up you'll see for yourself its a nice product. It made a massive inprovement in venting the cases on my old TC's I hope it works the same on my new bike. Thank you for you video you always make me laugh along with you. God bless and be safe.

[@joesainato8051]

Mine will be here Saturday. Did extensive work to the motor and it seems to be an incredibly wise investment

[@scottfhscottfh]

DK CUSTOMS sells the catch can $ 65 USD and the renew kit for $ 12.50. In stock current as of 15 April, 2021. AMAZON, sells the black catch can from Golan, same as yours.

[@leehornx]

The trask vent M8 has shipped after 2 day wait. The difference I think will be the transmission cover doesn't have all that much oil and it's not at the rear where all the oil goes during acceleration. Plus it just looks badass

[@fltrx19rider14]

Good video, re-routed my fueling dipstick to the rear as well. Well engineered product, but still pricey. 2019 rg, used a-1 vented stick 1st. Less money, but very basic. No valving, however larger diameter hose , better venting. Could smell crankcase fumes coming thru the filter. Stiffer, fatter hose, more difficult to route. No quick disconnect either. All things considered, higher priced fueling product offers more convenience, easier routing of the hose, and better engineering. Just my 2 cents...

[@wendellburks6546]

Watched your videos all the time. I was interested in your evaluation of the Feuling vented dipstick. After hearing your opinion I installed one on my 2018 M8 ultra with a stage 3 114 ci. I was impressed with how smooth the engine ran. Thank you for your honest opinion of this device.

[@iancatlin5985]

I got the A1Cycles Ventilator (I'm cheap :-) ) and it works great - in fact I think it may actually be better as it allows the air to move both ways (I think the air pulses in and out of the vents), I've also done a (cheaper!) DIY vent kit for the head vents by routing through the airbox and out, I had noticed even with a vented dipstick you still get a small amount of breathing via the head vents... defnitely feels smoother running and nicer throttle pickup. Great video, thanks!

[@kadimsilahtar]

A1 all the way... it has larger opening and hose as well, I placed the filter under the tank. The only downside is you still need your stock dipstick with you.

Great video! I just my first “ new era” Harley (StreetGlide Special) about a month ago. I came from riding a 90’s model Evo and a Shovelhead for YEARS! So all of this is new to me. I have more power and throttle response that I’ve ever had. Even if I don’t do the upgrade, I’m still good!

[@shanecoker8566]

The air/oil separators inside a twin can rocker box are the same thing Feuling used on their dipstick. I’ve now added a Feuling dipstick to my twin can motor after replacing my separators. I didn’t know about the Feuling product until after I had taken my rockerboxs apart.

Will installing the vented dipstick eliminate the need to alter your crankcase vent bolts?

[@jamessouthworth1699]

I remember the chocolate milk that used to come out of the catch can on my Sportster. My catch can was about the size of a 7-ounce Red Bull can and it had a valve on the bottom so I could drain it.

[@tommiller8714]

Feuling Vented Dip Stick: The allen wrench for the setcrew (Cap, clocking) is 0.050". Not a common size. I had to make a trip to Harbor Freight, and finally found an 0.050" but had to buy a set [of allen wrenches] to get the one 0.050" allen. Harbor Freight is cheap; the allen set (assorted sizes) was only $7 or $8. I also have the piece from Trask (Trans. top cover plate) with the breather, but haven't installed it yet. Still working out my own engineering for the EBS (head breather bolts) utilizing the HD SE Extreme Ventilator AC. Thinking about doing a 114-to-117 Stage 3 or Stage 4 kit (I know, HD SE also has the 114/117-to 122 Stage-3 and 114/117-to-131 Stage-4 kits available, but not C.A.R.B. certified (yet?) for California.

I have the EBS that I’ll put on my bike after Harley is done with it. The Ornery One did a real good review of the dip stick you have. The Dealer installed his and they kind of ran it the same way you did. I like it but I’m not willing to drop the $280 for it right now. Good review on the EBS.

[@stallion5110]

Try a screaming eagle heavy breather no problems and made for the upgrade It works

[@ProfessionalMonkey]

I have a heavy breather on my Limited. This is about putting in an EBS. A heavy breather doesn’t fix blow by.

[@scottfhscottfh]

The fueling works great to reduce my blow by on my 103 HO engine as well! I noticed the difference right away.

[@ProfessionalMonkey]

Yes it does!

[@scottfhscottfh]

Trask vents the transmission and primary whereas the fueling only vents the crankcase. These are separate components. The M8 already has a vent on the primary case, I would think the Trask really serves no purpose. Isn't the Trask design and the M8 HD vent on the Primary more for the possible reduction in transfer between the transmission and the Primary. You can get a M8 vent retrofit kit for older M8 engines from HD. In days gone by HD use to have a vent similar to Trask on older engines.

[@freebehindbars8654]

DIY breather vent and a $300 vented dipstick. Seems HD could manufacturer one and cut us a break since it’s an issue designed into our bikes.

[@grounded7362]

I really like my Feuling vented dipstick. So much easier to read. I wish I could find a transmission dipstick that was as easy to read. Most of the time I can't tell if the oil reading is in the x area of the trans dipstick or not.

[@michiganborn8303]

Just got my Feuling vented dipstick last night. Probably be Wednesday when I get enough time to install it. Just curious as to how I should run the breather line. Some say run it up and over and the filter should come out somewhere down where I mount my sprit bell is but if oil does go up through that line, wouldn't that create a syphon effect? Other people say keep the line/filter high to avoid that. I think I'll route it the way you have it on this Road Glide so if there is oil to come out that filter there's no chance of getting that oil on the tire. That would be bad. I thought about adding the Trask because it gives it even MORE breathing ability.

Thats a check ball problem. Its warn out, so oil seeps past into the crank case from sitting. Then you start it and that oil shoots out the breather all over the ground. Replace the check ball, use the old one on top of the new one, use a flat punch and smack it with a hammer to seat the new ball. Then toss the old one and put the line back on. My 90 heritage does it as well. Easy fix!
