Actually, I got 66 mpg on this trip here... http://advrider.com/forums/showthread.php?t=797288 One of my customers got 67 on his EXC so...2 data points. I just put a JD Jetting tuner box on the bike & preliminary numbers look alike a slight decrease to maybe 60 ish. Need more data. The JD settings (it comes set up for an EXC / XCW) are just slightly richer in all "modes" (RPM ranges) by maybe 5-10%. Bike does seem to run smoother at all RPMs, tho. And, BTW, my local dealer has no 13 L stock & agrees that the tank is BO.
It's spelled nit-wit. You can't even spell beyond a third grade level. You do know that you can convert centimeters to cubic inches, right? If you start with 510 CC's (or 31 cubic inches) (since we are talking about the 500 EXC) then even if you bored out the 510 to the maximum (no replacement for displacement) one could still spend more money to build an engine that would hands down beat a bored out 500 EXC (since one of the first things someone would do to gain HP is to bore it out). There are still motorcycle manufacturers that use cubic inches vice centimeters to measure engine displacement. Finally, both of the quotes "no replacement for displacement" and "cubic dollars will beat cubic inches every time" come from the automotive world (but they are not exclusive to the automotive world), I heard Don Gartlits and Mario Andretti say the same thing at Ontario Motor Speedway on afternoon when I was in the pits for autograph signing back in the mid 70's. As far as your reading and comprehension skills, they are lacking. I was not the one who originally use the "automotive terminology", that was this guy: "Originally Posted by SteveO Well put; there is no replacement for displacement...." I answered his "automotive terminology" humorous post with the correct "automotive terminology" humorous response. Nothing more, nothing less. It's YOU nit-wits that can't deal with it. Done.
Sure, the first thing that you do is start with a bigger displacement engine Displacement, volumetric efficiency, effective compression and RPM. Those are the focal points for making HP. Regardless of money, you con only do so much with the last 3. From there...no replacement for displacement. Relatively cheap and damned effective.
Didn't you consider that you could put 4g of fuel in the bigger tank? Or 2.2g? Or 3.5g? Guys just can't resist fillin them up I guess? As to a 3g option, sounds like just the right amount for a 2 hour scrambles. 2.2 will do a 1.5 hour race on my 570 Burg. I doubt another lap would be possible though.
Don't worry. According to an engineer, that tank would then have excess capacity and the design would be considered "flawed".
Stop stop your hurting my feelings! oser Im going to go ahead ands send you a PM so we can keep this CRAP out out of an otherwise good thread!
Well, considering that the KTM tank will be on back order until August, at the earliest, I'm going to get the Acerbis 5.3 Gallon tank and just put a couple of gallons when single tracking....... Should have thought of that earlier... :huh
Went out & tested a few bike mods yesterday with a BRP local. His BRP was reborn after some ahh....altercations. I had added a new JD Jetting tune box to the 500 EXC. We got in 225 mi from my house. Not bad for starting at noon. Only a few pics due to unwillingness to slow down. This was all at 4500 to 9400 ft altitude. There were incidents of Orange abuse spotted in upper Red Creek... Timber canyon, etc... Much smoke n ash from the sadness down south... Meditating at the turn to head back north. Note Kev pensing in the shade.. Unlike others who have installed the JD box, I don't feel a big "surge" in power. Maybe it is the altitude. I do notice that it seems to run smoother in all conditions. Have not yet deviated from the original JD settings for the EXC. And the mileage dropped to 55 mpg from 66 w/o the box. As suspected but still tolerable. Physics. (Note - My old BRP would get 40 mpg. Kev's get less do to a pumper carb mod. Fun but...) Also, I put 3.4 gal into the 3.4 gal tank for 185 miles. Still running but for how long. Been running 13 / 45 cogs since the early days. Highway rides are inevitable between the dirt around here & 75 mph works but .... I am going to try the 14/45 combo again for this type of riding. The 13/45 works really well in tight single track but this bike runs well on the low end & I think it can do well with 1 tooth up. Next...
I need the part numbers for the four plastic lenses in the dash, FI, Fuel Level, Brights, and Turn Signal. I screwed up when I was installing the HDB computer protector and broke them. Ironic given the protector is supposed to keep that from happening. I am a dork. Any help with part numbers would be appreciated. This is a great forum and has been very helpful. THANKS
Wish i had done it sooner. I can still singletrack the 500 and no worries about fuel. It handles great!
You do realize that all KTM 520,525,530,500 bikes are the same engine size right?? All of those bikes are 510.4cc just have different names! Marketing 101, change them name so you buy a new model.:huh
You do realize that they were talking about the difference between the 5xx and a smaller motor, right?
No. Guns_equal_freedom was saying he was disapointed with his 500 compared to his "530" which in reality is the same 510.4cc as the rest of the bigger bore KTM singles. The 500 has plenty of torque once you put a pipe and fix the lean fuel injection. I had 300 hrs + on a 530 and 135 hrs on a 500 so far and both are great bikes. Different strokes for different folks I guess. I can say that the durability on the 500 is WAAAAAYYY better than the 530. I put 2 pistions in my 530 by 135 hrs and im still on the stock piston in my 500.
WTF, your post is coming out of left field. Where did I say I was disappointed with my 500? I don't even own a 500. My bikes are listed in my signature line. All I did was put a link up to a guy who owns a 500 and is not happy with the power and then I put the comment "there's always one". Then someone posted up "no replacement for displacement" to which I replied "cubic dollars beats cubic inches every time". That unleashed a shitstorm of butthurt for some posters with no sense of humor, some posters who are not old school gearheads and some posters who don't get that the first thing ANYONE does who is serious to get more HP is to increase displacement. Example: You increase displacement to the maximum. I also increase displacement to the maximum. In addition, I am now spending money on blueprinting my engine, titanium valves, performance cams, ported and flowed head, larger carburetor, lighter wheels, different gearing, and more money and more money and more money. So, while I don't own a 500 I have a friend who owns both a 2012 EXC 500 and a 2013 XCW 500, I have ridden both and they both are better bikes than my 530 is. I am trying to sell my 530, it's up for sale in the flea market and on KTM talk so I can buy a 2013 XCW 500.
