Question for those who have done the external crank breather
General Topics/Tech TipsDiscussion on break in periods, rider comfort, seats and pad suggestions. Tech tips as they become available will be posted here.
Went out and did some shopping the other day . I found everything I needed , of course I had to go to 2 different stores , but It'll get done . By the time it's complete , I should have it done for less than $50 . I decided that I'm just just going to go ahead and drill and tap the fittings into the air cleaner backing plate , more work , but aiming for a cleaner look . I'm using some galvanized steel tubing and some caps to make the canister which I will polish to a chrome finish , along with brass fittings and a pressure relief valve as a drain . I'll be sure to take some pics of the whole process .
Here is what I did to mine and I put a list of parts on the description.
I did not do a catch can instead it just goes to a little PCV air filter I had lying around and vents. I have had no oil drips or marks.
I do not make these videos to make money or promise to be very professional. I do them for my own personal fun and hopefully help another person as a bonus.
Excellent video , thank-you for posting ! You sure did give me some helpful advice on how to proceed with my project . The bike isn't back from the shop yet , but I'm going to start the catch can today and hopefully finish it up in a day or two . Great idea on holding the baking plate in place while drilling out the holes , and cute pups you got there !
I went out and did a little shopping , picked up some gal steel fencing parts to make my oil canister , bought some fittings and some hose . I started making the canister today , took about 3 hrs in total .
This is what I started with
First thing I did was modified the caps by cutting the lip off them and grinding the top down to create the flat surface .
Once that was done , I cut a piece of pipe and started sanding and polishing the parts , that was the longest part of the entire job .
I decided to cut the pipe a little shorter , then used JB Weld to secure the bottom end cap . The top end cap was drilled with venting holes and I added a fitting to attach the hose . Here's what I ended up with , just have to decide where I'm going to mount it .
My bike is being delivered to my shop tomorrow , so I'll be able to start on the air cleaner mod and run the hose to where I decide to mount the canister , so far so good .
One thing I did on my catch tank was to cut a piece of bulk steel fuel line and beveled and JB Welded that to the inside of the breather fitting to divert the breather vapors down into the canister. My thought being that the low pressure outside the tank would make stuff come out of the top rather than settle to the bottom of the catch tank.
Yes , that's the plan , I have a peace of steel tubing that will fit inside the fitting and go down about 3/4 of the way , which should leave about an 1" or so of space for fluid to collect . I also plan to place some very coarse steel wool towards the top to filter the venting holes , not sure it's needed but I'll try it out anyway . I can't recall where , but I read there should be a couple of smaller holes drilled towards the top of that tube , for whatever reason , I'm not sure , maybe in case it gets to full of fluid and blocks off the bottom of the tube , causing it to not vent properly .
I was also planning on mounting it to the down tube at the front of the bike at the lowest point , but I'm wondering if I might get a good whiff of oil when I'm stopped at a red light , I might have to find a spot closer to the back of the bike instead . This is my first attempt at this , so it'll be trial by error .

Wow, that's an amazing transformation of crap post metal to sweet catch can - great job. Post up some pics of the finished project, when done.
Regarding the whiff of oil, only rarely does that happen.
I mounted my catch tank on the frame down tube, left side, as low as possible.
I'm going to go ahead and mount it on the front down tube , unfortunately it won't be until spring before I can test my concerns about the oil smell , you've eased my mind on putting it there , can't be any worse than sitting behind a diesel truck for a couple of minutes , honestly like that smell .
Iceman , thank-you very much for the compliment , I was going to post up some pics after it was all done , but I couldn't wait , It definitely turned out better than I thought it would . I'll be making arrangements to get the bike delivered today , wish I could ride it but it's to damn cold out , once the bike is here I can start the air cleaner mod and bolt everything up . Guess the machining coarse I took in high school finally paid off .
Help ! I picked up some fittings to attach to the backing plate , but I'm not entirely sure exactly what size drill bit and tap I need to get this done . I've done tapping once or twice , but lets just say I got lucky . I do plan on doing a trial run on a piece of scrap metal first before I tackle the backing . If for any reason I blow this part of the mod , I'm fully prepared to purchase a new one , I won't like it , but I will .
The receipt shows this part as a Coupler 1 4 HB X 1 8 MPT . Not exactly sure what this means , other than the size . Here's a pic of it also . Sure wish I new how to make these pics smaller ...
