what's the status on your builds?  anxious to see them.

 
We are in that almost done mode,... you know,... where we are 95% done, but the last 5% takes as long as the first 95%.  Plus, some other "priorities" have been getting in the way temporarily.  Realistically, we hope to have them running in a few weeks.  Thanks for the interest.

[size=14]Okay okay okay,...

I finally did something about the RYCA-supplied air filter.  The problem was it would almost fit, but not quite.  It fit well enough so that if it were jammed in place and the hose clamps torqued down enough, it probably would have stayed in place.  It just bothered me, though, that the carb wasn't fully "popped" into its place in the intake rubber, and the filter was just a little cockeyed as it was torqued down onto the carb.

At first I tried just relieving various clearance problems around the edge of the filter.  I peened the frame crosspiece up about 1/8" as well as grinding off part of each nut welded to the frame crosspiece that holds the tank down, and, grinding off a lot of the head of each hold down bolt.  I also ground away some of the RYCA battery box (the upper/forward) part that interfered with the filter.  That is the box on the right in the pic below.  That didn't work well enough.

So,.. I got adventurous.  I added a couple of tabs to the frame just aft of the frame crosspiece.  
  --- It was simple.  I found a large seatbelt washer, cut it into fourths, and MIG welded each fourth into the frame.  (two on each bike)
  --- Then I cut that upper/forward part of the battery box back.  I put some blue tape on the modded area just to make it more illustrative for the pics.  That is the box on the left in the pic below.

Then I tested for a fit, and, ...YAY!  The carb is fully popped into place and the filter fully fits on the carb, which just touches the peened up part of the frame crosspiece.

Instead of using the RYCA bolting scheme,.. I'll use the stock system to hold the tank down, making sure the bolts don't poke through the stock welded on nuts, or they will hit the filter.  Two additional bolts will fit into the holes drilled through my welded-on tabs, and drilled into the battery box.

For those who don't have access to a welder, you might consider making a tab in the same location cut out of a piece of aluminum angle and pop-riveting it into place.  I was heading down this path for a while.  I actually made one tab.  But then I changed my mind and decided to weld it all in.

Now,... what to do about the breather,.....




Cute, huh?  This how I clamped the tab into place so I could tackweld it.





Two tabs welded into place.  All that red signage underneath is just to keep tiny hot chunks of metal off the bike whilst welding.






Here are the two boxes.  The one on the right shows my first attempt to get enough clearance, with some of it relieved where it interfered with the filter.  The one on the left has been cut back to fit onto the new tabs.  The tape is just there to emphasize the changes.





The next two pics show how the filter just fits now, and how the box is bolted in.





This last pic shows how the stock welded-in tank hold-down nuts are ground off to clear the filter.  The pic also shows how the cut-down upper-forward part of the battery box bolts in place.

what is your thought on this idea:

what if you were to cut the whole center tab off of the frame and move it back to the area where you added your tabs?  looks like it might clear the entire filter

The tank/seat mounting tabs need to stay in place. The material between the captured nuts might be able to go.

Bob,
No need to go through all that. Like you, I started hacking away at the battery box to make the K&N fit until it looked like I'd weaken the box so much that I stopped and changed filters. I found a much smaller and good fitting filter from Uni, their Universal Clamp-On.

By the way how did you remove the "chrome" from from your headlight bucket to get it ready for painting?

"No need to go through all that."  We each have our own whims. I didn't want to discard the expensive RYCA-supplied filter.  Also, with the metal backside, it lines up with the solution I'm going to use for the crankcase breather as well. What took the most time was me just pondering, and trying this and trying that.  Now that I know a way to get the situation handled, I'll bet the second bike will take maybe an hour to cut down the battery box (10 min with a hacksaw), weld in the fourth-of-a-washer pieces (30 min), drill the holes (5 min), and tidy it up (whatever min).

"Going through all that" is not a very big deal if you have a washer to cut into fourths and a MIG welder, or even a cheapo flux-core welder you can buy at Harbor Freight brand new for the cost of a couple of K&N filters.

I'd like to see some pics of your Uni filter set up.

I just peeled the chrome off the plastic.  It took a while and it needed some sanding to smooth it up for a few coats of wetsanded scratch-fill primer.

I agree with you on the "we each have our own whims" thing. These are custom bikes, so indulging our "whims" is what it is all about and makes each bike our own.

Information on the Uni filters can be found at http://www.unifilter.com/online%20catalog/universal.html
Scroll to the bottom for the Pod Kits. Not cutting of any Suzuki or Ryca parts needed.

When you say "peel" the chrome, what tool do you use to do the picking with gouging?

It was already scratched in a few places with loose edges, so I just started there and began to peel,... sort of like getting the shell off a stubborn boiled egg.  Mostly I just used my fingers to peel it off, once I got it started.  I used a knife to lift up an edge to get it peeling again sometimes.

Here's one solution to the crankcase breather.  I poked a hole in the RYCA supplied K&N air filter, put in a grommet, inserted a crankcase breather (maybe fits a Taurus), and hooked it up to a shortened breather tube.


Here's the RYCA filter with a 15/16" hole put in it.  Next time it will be offcenter about 1/8" for clearance.



Here are the four parts to be assembled



Sources for the parts.



Grommet installed in the K&N filter.  Next time I'll use a grommet with a wider ring around the outside because the filter has a really thick coating of rubber inside the metal, maybe 5/32" thick for the metal and the rubber.



Breather installed into grommet (tight fit), elbow attached to breather with a piece cut from existing breather tube.  In this pic the elbow sticks out too far, so the tube on the breather was shortened some, as was one side of the elbow.



Other side of the breather assembly.



Air filter and breather assembly installed.  It fits fine with NO room to spare.



Left side view.  (or is that port side?)  (but what if I am facing the bike?)  Wink



View looking up.



Another pic but with flash this time for diff lighting detail.


=======24 Dec 2023 update; Sorry about the missing pics, I'll try to go through this thread and tidy all that up=====

I may drill a tiny (maybe .020") hole in the white (soon to be painted black) elbow for drainage.  It's the low point.

I really won't know how this will all work until we start 'em up.  At least we have a token effort in place for the tree huggers, and it looks fairly tidy.  Cheap too,.. several bucks total.

It looks like maybe you can rotate the PCV valve counterclockwise and make the elbow snug up to the frame and no longer a low point. Even if not, I bet any dribbles of oil will just work their way through the elbow without your having to drill a hole in it.  That would also eliminate the chance of dust getting sucked into the clean side of your filter.

Great work.  I envy those welds.

I can't interject much on the technical side, but I must say you take some really nice, crisp, clear photos!   Smiley  Should be a great help to those in need.
