KTM 500

Hi guys, Im new here so if this is in the wrong section i apologise.  I wanted to make a thread on a really great friend of mines 2013 ktm 500 exc. Unfortunately he had an accident riding in the Northern Territory, Australia and passed on the 20/10/13 after a week long coma, RIP 'AZZA'. He had this bike for maybe 4-5 months brand new. I inherited his 500 from his mother who did not want it and said she would like me to have it. I was honoured. Thinking the bike would be a right off but thought it would be a great project, found that there was little damage. Couple scratches down the right side of the six days plastics and scratched akro slip on. A friend and myself went over the bike to find any problems. Twisted forks which was resurrected as soon as we loosened the clamps, found out for myself that the suspension was not set up properly for his weight as the power parts bashplate welds were split all the way so we put it down to casing out hard.

His mother had a lot of photos and videos that he had taken of different aftermarket parts that were going to go on the 500, so i thought it would only be right to spend the $$$ on the bike how he would've wanted it. 

After going over thinking we'd found all the problems, came the task of finding and spending $$$ and waiting for parts to arrive.

At this stage i had only started the bike and rode it up and down the street maybe 5 mins.

All the parts i could afford had rolled up, so i started the process of removing the old and in with the new.

All done and ready to ride, fired her up and took it slow. Found a nice little dirt track to open her up, got to 3/4 throttle and held on but there was nothing she was just gutless. My old Yami wr 400 would have ran rings around it. Tried a few times, headed home. Sat in the shed scratching my head.

After searching forums, youtube and asking everybody that knew about bikes about this problem, everyone pointed towards the injector and or fuel. Azza had already payed for the emissions kit to be pulled off, I even double checked there work.

So I cleaned the injector, changed the micron filters, changed the fuel sock and fresh fuel, try again to no avail, it just felt like it was starving for fuel everytime i twisted the throttle and this was every gear.

I gave up for a while thinking i was going to have to take it in to someone. I got the bug again to find out for myself what it could possilby be. I scoured the net reading everything about this model, and was also fixing little things like the stupid kick stand and airbox cover, overall just general improvements. 

 

Then to my shock yesterday I come across a Thumper talk thread that Azza had made just months before he passed with the exact problem I had found with the 500. KTMPETE tried to help him but unfortunately it didnt work as the problem was still there so thanks anyway KTMPETE. After reading more on another thread some people said they had the same problem and that they had their mapping changed or got a jd jetting efi tuner and also removing emissions kit fixed it. $300 for this product i thought no worries, just as i was about to purchase, I found another thread stating that a 2013 ktm 350 exc had exactly the same problem and the bloke found the airbox had a restrictor in it. I thought no way could it be so simple, could it be the same for the 500, I had read 1000+ posts on the 500 and no one had ever mentioned this and there were many people pissed off that they had the same problem. So today I thought what the hell i'll give it a look, ran to the shed and ripped the airbox cover off and pulled the air filter off and stuck my head in, and there it was. I took to the bike like an Impatient kid on xmas day. Undone the subframe, lifted the subframe so the airbox and throttle body disconnected and out it fell. After putting her back together i gear up and head out.Thank the dirt bike gods!!! it was fixed it ran like an angry beast, it was a sweet and sour feeling I had knowing I had finally fixed Azzas pride and joy. But also knowing that he had the bike for months and never had the chance of really knowing the 500's full potential saddened me.

So to anyone out there with the problem of twisting the throttle and the bike feeling like it is bogging out after 3/4 throttle or it feels you have no power, before you spend any cash take a look in your airbox for the restrictor, takes 5 secs to spot. If you can see the throttle body from inside your airbox then it has been removed. Also added a couple pics

 

I hope this helps anyone that has the same problem as myself.

 

Did anyone else run into a similar problem???

Hey mate,

 

NT rider myself, my 200EXC had a plate that was supposed to be put in that would block around 2/3rds of the intake. It was jetted down slightly to suit. I never realised what it was for ages because it wasn't installed. 

 

Might have a look at my mates 450 over the weekend. Sorry to hear about Azza.

I'm sorry about your friend. Interesting post, my 500 did not have this in the USA so I'm thinking this might be specific to your region. Which is interesting because I usually think of the USA bikes as being the most restricted. Thanks for sharing!

Yeah thinks for the post, never seen that restrictor before or knew it existed, especially on the Australian models.   I'm shocked this is the first we've heard about it, you'd think the Austrailians would have been complaining a lot more than the Americans.

 

Your friend is probably smiling that you found it.

Any chance you could report back on the 450??

Hey there guys really appreciate the kind words, im sure 'AZZA' had a smile on his face as well. Like I said I had read thousands of posts specifically on the 500 and no one had ever mentioned anything about this dirty little restrictor. So far I know of only the thread i read on the 350 and myself that had the same problem and he never said where he was from either. Im assuming it is region specific though. 

Any chance you could report back on the 450??

Yeah shouldn't be an issue. I'm looking for something restricting airflow into the throttle body, through the airbox, correct?

You can see in the picture , the restrictor is blocking the air hole to the throttle plate, it should be easy and obvious to see if its there.

+1 on what Spud said, the middle picture is the restrictor and the last picture is the restrictor in the airbox. Otherwise you will see the butterfly. i would post another picture but i cant work out how to  :smashpc:

Sorry for your loss. No doubt AZZA is riding with no restrictions in the best conditions now. To honor him would be to ride the wheels off it...within your limits and within the conditions limits of course. Next month marks the one year since losing my cousin "SHRED". We gave his smoker to his nephew who is currently riding it everywhere SHRED wanted to in the PNW. Ride AZZAs bike and take his memory along with you! Glad you got it sorted.

Absolutely!!! my friend would be ashamed of me if it just sat on the stand looking pretty. Looking forward to this weekend  :ride:

sorry to hear about your friend... i dont think my 2012 had one but ill have to check with my friend because he bought it new but the way my bike runs i doubt it... and im with oldfuddy on To honor him would be to ride the wheels off it... i would want that and im sure all my friends would want that as well... best of luck with it..

Sorry about friend. Did he have the accident on the bike? I find it a bad omen to ride a bike someone was killed on. IMO, restore it and park it!

Yes unfortunately. I thought the same thing but after speaking with our good mates, his brother and knowing my friend down to a tee, he wouldn't want it just sitting.

So sorry for your loss Morris. What an honor he must feel to have such a great friend to keep his memory and passion for ridding alive. Glad you figured out the issue, I would have never guessed there would be a restriction in the intake. Enjoy you new found power plant and stay safe knowing your friend is smiling from up above.

Hey thanks KTMPETE yes I'm certain he would be proud as punch knowing his 500 is running and looking just the way he wanted it to. My mate was a top notch bloke so i felt it was the right thing to do as we are both dirtbike fanatics.

Yeah i got lucky finding the restrictor, it has been a rare case.

RIP AZZA. Glad you figured out the problem. Enjoy the bike because I know he'd want you to.
