dumbfounded by electrical problem 02 520 mxc

Recommended Posts

So I recently purchased a 2002 520 mxc I have put around 150 miles on it problem free, love the bike. This tuesday i was all geared up and ready i made it about 75 yards from the truck and the bike quit. I pulled it apart and discovered there was no spark. My buddy has the identical bike. I have switched out all his ignition parts with mine to try and rectify the problem, no such luck. I have replaced the cdi, coil, stator, pulse generator, spark plug and wire. Now im lost. The next step in my mind is to start going through every wire in the ignition system looking for bare wires or bad grounds. Any advice will be greatly appreciated. thank you

Does the voltage regulator have anything to do with spark, I understand that the regulator is for the acc. i.e. lights and horn

Probably not it for you, but you should know that there are TWO fuses.

My electric start quit after a crash and it took me forever to figure it out. I saw one good fuse and thought there was only one. But the 2nd had fallen out. Worth checking.

good luck

      Looking for something a little lighter and faster to supplement my xr650l and I think this bike might fit the bill. I'm hoping there are some owners here who can give me some insight into the typical experience with this bike. The question I'm most concerned about is how many hours these engines last before needing a rebuild with normal trail riding? Also, how do they handle in technical terrain? How about on the road? 
       
      The machine I'm looking at has about 75 hours and 1,500 miles on it, all stock other than a lectron carb, and comes with some dualsport lighting not installed. The current owner's asking price seems pretty high at $4500, but he seems to be a communicative, eager seller, which is practically unheard of in Upstate NY where the vast majority of dirtbikes on Craigslist are owned (or "owned") by rednecks trying to flip them. I'm willing to pay a little more than market value for this reason.
       
      Thanks for any input!

      Hi all,
      I got a set of the Axis passenger pegs to fit my 14' 500 exc. The bike does have the alloy sub-frame, but I'm curious if anyone has used this set up with success without destroying the sub-frame or their wife/gf? 
       
      Short trips like errands and rides out to the coast for hiking. 10-15 miles on the longer rides, and likely 0 miles on the highway, as she is not super stoked about riding. But our job kinda doesn't allow multiple vehicles. Yachties. Also shopping a sumo set up at the moment too. 
       
      Thanks folks!!

      Recently,I took a trip out to Colorado for some R&R on a family vacation. I brought my riding gear and had planned on renting a bike, but I was too late and at least what I looked at, there was no availability for my timeline. Bummer, since I'd not ridden the rockies in over 4 years, something pretty special when you live in flatlanderville (Florida)! 
      But, behind the scenes, a couple of TT'ers were at work! Through TT, we recently hired a fine, young gentleman to head up our advertising sales team,( @Freemotion ) and he pulled some strings with a local who had a well equipped  KTM 450XC-W that is his back-up machine. His new love is a 2019 KTM 300 TPI and it was gorgeous!
      So, a HUGE thanks to @Freemotion for greasing the skids in getting me a skoot and to @G 9.5 for generously lending out his bike to basically a stranger. The weather was great, so was the company, and the riding was epic as far as I'm concerned. I'm still a bit humbled by the generosity, so I wanted to share a story that I bet isn't as uncommon among the riding community as one might imagine.
      Dirt bike people rock! 🤘

      Hello TT peeps. I currently have an 11' Ktm 450 exc which i am converting to sumo. Still on the fence about getting cush drive rims or standard rims. Not too much info on what cush drive does for wheelies. I know its smoother on the tranny and chain but will it make much of a difference with slower wheelies/stunting? I had a DRZ with standard rims and slower wheelies were very choppy and almost impossible to control smoothly. Any advice/tips/help will be much appreciated. 
      Also.... will 5" rims be pushing it for chain rub? Should i just stick with 4.25"?

      Hi, I was wandering if anybody has recently bought or sold a 2014 or 2015 500 exc?  I'm trying to get an idea as to what they worth presently.  Thanks for any help.
