sold my 426, bought 02 520 and need help!

Recommended Posts

Well, after 4 Yamaha 4 strokes I made the change. I just picked up my new 02 520sx yesterday. A few questions. It didn't come with a manual so I can't read up on it. First, what octane gas and what type of oil?

Second what's the best aftermarket exhaust with a spark arrestor?

Thanks

You should have got the manual....go back and make them find it ;-)

From the manual:

First oil change @ 3 hours or 20L of fuel.

Then every 100L of fuel or 15 hours. Use FULL Synthetic oil API classes SG or SH or better ( plain jane 15w50 MOBIL 1 meets the spec). I've got Maxum4 15w50 in mine now, same stuff Dowdy gets paid to run :-) Remember two filters and two screens....if you're rather pay about $9 for filters rather than 30 for the KTM part email me and I'll tell you where...

Only guy I know that's gone to an aftermarket pipe is a PC T-4. It's nice, saves a couple of pounds and has a removable spark arrestor. I've been an FMF guy for years but I think I'll go PC if I change out this one. The changable end caps and removable sparky make the PC a much better deal- IMHO

Chris, thanks for the reply. I am fairly new to thumpertalk so maybe I am missing something but I couldn't find your email. Please email me with the info. regarding less expensive filters at rjpyne@mathed.byu.edu . Also, do you know what is a reasonable price for the PC T4 exhaust system. Could someone also inform me with regards to the airbox mods that will increase performance?

Thanks again,

Rob

It should have come with a pretty comprehensive set of papers. Included are WP manuals for fork and shock, setup papers, and an excellent owners manual. All in a neat KTM logo nylon pouch. Contact the dealer and get it.

As for the exhaust, ride it first. There is so much power stock, and easy power gains with holes in the airbox side cover, a pipe is not really necessary. Uni makes a little round filter set for the side covers, just use an appropriate size piece of copper pipe (home depot) heated up and push neat holes in the cover. The round filters are generic and made for any bike.

Good luck

Pretend it's flat and give it the gas.

See this thread for info on cheaper oil filters: http://www.thumpertalk.com/ubb/Forum11/HTML/000544.html

I use pump premium with no problems. I use Belray EXP semi-synthetic oil. KTM service classes told the dealerships to recommend the semi-syn. There were a small number of folks who were experiencing premature clutch failure with fully synthetic. There's an article in a recent DB mag that has KTM's Tom Moen using totally non-synthetic, dino oil in a article about how to change oil in an RFS.

Good folks, the filters are about 4.50 each...they'll ship them ups....I buy a few at a time ;-) Also if ( God Forbid ) you ever need engine work, Sam the owner is the only guy besides myself that I'd let work on my bike...first class Guy and Mechanic.

Premature clutch failures with full synthetic oils? Interesting. Does anyone know more about this?

First, this is not common. It was stated that some of the top racers were going through clutches fast in the RFS's so they switched to semi-synthetic oil to help stop that. I've read of a few early clutch failures on KTM RFS's but not many at all overall.

Hi Chris:

It is good to know that you have confidence in Sam to work on your bike. That way I know where to go if I need some work done on mine.

Take care,

      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.
