The slots seem to be closer to what the aftermarket fenders have, so that's my vote.

The Honda fender is pretty tough. I think if I leave enough material between slots, the fender can absorb rock hits without fracturing. I also think slots might spray less mud on the oil cooler than a larger hole covered with hardware cloth. I'm going to aim for 3/4" inch clearance between the fender an oil cooler, as you suggested.

I think that the slots as you have them laid out would be good. How do you plan to trim the slots?

That's my question too. Maybe a router?
For me the holes would be easier to make cleanly with a step drill.

If I cut slots, I want to keep them about 3/16" wide, to maintain fender strength. I also want to space the slots about 5/16" apart, for the same reason. I would make the slots about the length of a Dremel cutoff wheel, to minimize labor, and to maintain the strength of the fender. Finally, I would stagger the slots in each row, also to maintain the strength of the fender. Spud

I'm going to buy these Harbor Freight, step drills today.

How do you guys like this pattern?
I want an attractive pattern, that is not too difficult to manufacture. However, function is more important to me than form. I want a hole pattern that maximizes the following attributes. Provides good air flow Cleans itself from mud Protects against rocks Maintains fender strength Looks as attractive as possible Spud

As far as the specif pattern goes you can't go wrong.
No matter what you're going to run cooler than stock. You win no matter what. :wink: Personally I'd go with holes rather than slots. Faster, cleaner, easier. Personally I know I'd not cut a perfectly straight line with a Dremel, and my experiance shows that cutoff wheels don't do so well on plastic. The plastic overheats, melts, and makes a mess and 'clogs' the cutoff wheel in short order. :? I'd drill holes and go for a ride and declare victory. 8)

Here are two more ideas.
After all, my bike is a Honda XRL. Spud

I agree with Doc on holes being easier. I've struggled with trimming plastic before, and that's why I asked what you used. I'll trim the new blue fender to suit the TS185, and I don't want to make a mess of it.

My Dremel tool worked great when I trimmed 2 inches off the front of my XR650L's fender. I guess you guys don't like the Xs. :?
In any event, drilling holes is certainly much easier, especially with the step drills. I suppose starting with fewer holes is better; I can always add more holes later, if I wish. What do you guys think of this pattern? Do you think I should drill 3/16", or 1/4" holes? Spud

Hey I just had an idea :idea: . Go figure. :roll:
Don't drill anything yet. Ride it with no holes and monitor the oil temp. Maybe INSULATE the cooler so you have a starting point to follow. Then un-insulate it and retest. Then drill some holes and retest. See if more holes helps. This should really amuse the OCD scientist/engineer inside ALL us Chinariders!

I would go with 1/4" holes after experimenting with the no holes test.
The holes will be easier to make. With the step drill you can start at 3/16" and then move to 1/4". If that is not enough move to the slots. Final resort would be the mesh I sent. I think you will be able to clean it enough with a stick if it plugs up.

OK. If I space the fender 3/4" away from the oil cooler, the fender should not melt.
I could duct tape a sleeve of cardboard around the oil cooler to establish baseline temperatures without the oil cooler. Then I could remove the cardboard to measure drops in oil temperature with the stock fender. I could drill a few 1/4" holes, and once again note oil temperatures. If oil temperatures drop with a few holes, I could drill more holes, if desired, to discover if oil temperatures drop even more. If necessary, I think I can clean the plugged, 1/4" holes by poking my ignition key through them. Spud
