So are you looking to build a supermoto out of your bike?

Eventually I'd like to get some sm wheels and street tires, but for now im just trying to make it dependable transportation

Skidplate mod part II

I think I posted recently that the bottom of my skiplate was starting to conform the the engine. My biggest concern about this was that the oil drain bolt was starting to become exposed. So I removed the plate to reinforce it.

This pic shows the shape of the dent in the plate.



I hammered the plate flat, cleaned the area to be welded, and cut a piece of aluminum for reinforcement. I had to leave enough room on each side of the reinforcing rib for the frame rails.



It was pretty difficult trying to get something as dirty as a skidplate clean enough to weld it, but it worked out. We'll see how well it holds up.

I shouldn't have gotten the oil temp gauge. Sometimes ignorance is bliss.



This only happens on extended technical uphills, but still, that can't be good. I change the oil every 1000 miles, so I hope that helps.

I must me reading the pointer wrong so the arrow is not pointing to 60 celsius (140 degrees)? Also have you checked the thermometer for accuracy?

The needle has gone all the way through the red zone; past 140 deg C (284 deg F). I have two different brands of oil thermometer for the bike. The other one shows the same results, but it has a pin at 140 which prevents the needle from going any higher.

I have checked my DR oil temp with an infrared temp gauge after a good hard run and it did not get that high. As you say it only gets that hot on occasion, look at the bright side...KLR's run that hot all the time.
Are you going to consider installing an oil cooler?

Yes, probably. I was hoping to do it this winter, but I've got a lot of other projects in front of this one, so it might be another year.

I doubt it. I've messed around with the jetting a whole lot. As far as I can tell, it's currently at the right mixture, but without and air fuel ratio gauge, I can't know for sure.

so, what is a normal reading, say going down the road at 55 or 60? also on gravel roads at lower speeds. does iit vary much with air temp....thx

The following are on flat trails on a 70 deg F day:
Open road cruising: 90 C
Quad track with whoops: 110 C
Technical singletrack: 120 C

lean jetting: add 10 C (this is with a main jet that causes a very slight amount of decel popping)

Warm weather (90 F): add 10 C.

Long uphills (+500 ft): add 20 C. This seems to be the biggest factor. I can be open-road cruising on a warm day (90 F) and the engine will be at 100 C, then I start to climb a mountain (even on easy jeep roads where I can keep the revs low) and the temp goes up to 120 C (redline).

It's only gone above 140 C twice, both times were on really steep (uphill) singletrack with obstacles that required lots of clutch slipping.

I'd really like to know how much ethanol blends contribute to high engine temps. If anyone knows where I can find solid info on this (not just people bitchin about change), I'd like to read more about it.

I wonder if higher octane gas will cool things down.

Oil Changes every 1K miles?

What are your thoughts of every 500. That seems like a number that more people report their intervals at. I shot for 500 but I currently have 700 on this batch of oil.
