Ok guys, I'm curious, and maybe it has been said before, but


How hot is too hot for these engines?



I know that water boils at roughly 212*F, using a product such as Engine Ice will increase the boiling point to about 255*F, which seems pretty darn hot too me, but I'm very curious as to how hot is too hot for these engines.

At what temperature does this engine get into the danger zone?

ignition key eliminator

Sicass switch for signals, headlight and horn (needed to create clearance for clutch lever)

I am probably missing something but . . . there will always be more.

First off, this is a sweet looking bike! Where did you get the ignition key eliminator? And I went on Sicass Racing's web page but couldn't find the top bar mount that raises the odometer up...where did you find that?

TIA

Stabilizer submount, top handlebar clamp, handguards and the odometer housing on that bike are all from Highwaydirtbikes.

Nicest and toughest stuff out there, I've got it on my Berg as well.

maybe when steam comes out ........

Yeah, which could be around 250*F.....that's pretty darn hot for a motorcycle engine......

What is the estimated rebuild schedule on one of these for 50/50 dirt/street?

I have 700 miles on my '13 and no increase or decrease in noise. my only complaints about this bike is the rattle noise and seemingly long break-in. It still smokes a little...I changed oil at 6 hrs and put some synthetic castrol power rs 10 w 50 in and it smoked bad. So I put in honda gn4 10w40 for more break in for a while.

i think maybe more because i just spent what it feels like my lifes savings on this bike. how ever the clunking noise quites down alot after pulling in the clutch. which i never herd on my 230l anyone know of what that might be? i herd it more today after i cleaned her up after a ride and put her away. any suggestions?

thanks chris

I gave him the 13 tooth countershaft sprocket from my XCW 500.
I bought a 15 tooth countershaft sprocket for my XCW 500.

We had to adjust his clutch and bump up his idle in order to make it a bit more ridable in the tight stuff.

His dipshit dealer didn't give him the bag of bolts for the kickstand and levers.

He has an aluminum skid plate, my experince is that they tend to amplify engine noises.

I told him he needs to pull the smog stuff and get a Rekluse.

We went riding on Sunday, there were 2 EXC 500's and 2 XCW 500's.

I had one on my 500 EXC. It lasted about 2 hours before it melted through and spilled fuel all over the motor. They are junk. Also, you have to splice the electrical wires on the tank- meaning you have spliced wires sloshing around in gasoline. Finally, the entire fuel pump installation is an abortion. All the o-rings on the fuel pump were damaged in the installation. It leaked from the bottom of the tank, at the fuel pump mount, from the minute it was installed

Here's the tank with two motor hours on it:



This is supposed to be the new and improved version of the tank, too.

I've heard a lot of people say they had good luck and a lot like me say they suck. I've purchased my last Clockwork product. $250 down the drain.

The boiling point of water changes with the water pressure. The cooling system pressure in most engines is limited by the spring in the radiator cap. If the coolant gets too hot, the radiator cap will release the pressure and you have boil over of coolant. The engine cooling system should modulate the coolant flow via the t'stat to keep the coolant at a temperature hot enough for decent thermal efficiency and hot enough to boil off water from the oil, but not so hot as to damage the oil and ultimately your engine. just my .02.

ok, sounds good. Got a rough temp number on that info.....

Actually, AV, that mileage is typical. As reported earlier, without any mods, I was getting 66 mpg consistently. After installing a JD Tuner is dropped to 50-55 similar to what Stu said.

With the 3.4 KTM tank that means about 185 mile / tank. If that is not tnuf range, I carry a RotoPax can. Seems to work.

Correct - The 1.75 was a brain-o. Sorry.

Additionally...The fan switch is mounted in the lower tank of the RH radiator. It is a 95 deg C switch. All good if is works. Mine failed during tight single track so some of the water / coolant boiled out. Who knows what this means. I feared that the rings may have suffered. That is the typical failure mode for excess heat. Bought a new switch & some rings for CYA. Installed the switch and kept running the bike. Initially seemed to be a slight increase in oil usage but it now seems to have stabilized. I expect this engine to use a little bit of oil.

My plan? Ride like nothing happened & enjoy it! This bike seems very abuse tolerant!

The following info is taken from this link:

http://www.engineeringtoolbox.com/oi...on-d_1492.html



Temperature limits of some commons lubricating oils are indicated below:

Oil	Temperature Limits
	oF	oC
Mineral	300	149
Petroleum	300	149
Petroleum, superrefined	350	149
Perfluorinated compounds	600	316
Polyphenolether	500	260
Silicones	500	260
Synthetic esters	400	204
Synthetic hydrocarbon	400	204

I remember a rot (rule of thumb), don't know from where, that essentially said don't exceed 250F with petroleum oil and 320F with synthetics.

Hope this helps SteveO.
