URBAN EXPLORING IS BETTER ON SUPERMOTOS

If urban exploring wasn’t exciting enough, get yourself a supermoto, dual sport, enduro, or mini-moto. There are many practical reasons these hobbies mesh.

No more parking problems: You can park your bike anywhere and it can be easily hidden.
Great Community: Urban Exploring has a great community of like-minded adventurers that love to get the blood pumping. The same can be said for the supermoto, dual sport, enduro, and mini-moto communities.
If you love adventure you will not regret picking up a motorcycle. Trust me.

MY RIDE: 2003 KTM 525 EXC

I picked up this gem at the end of 2017. A 2003 KTM 525 EXC RFS with 160 hrs. It would start with starting fluid and from 20 feet away was in perfect condition. I bought the bike for $2,900. The main selling points were that the engine had never been opened, one owner bike, lots of enduro engineering hard parts, 6 speed, street plated, ran and shifted smooth. The first thing I did after bringing how was adjusting the valves and rebuild the carb. Installing the JD Jet Kit was as first.  No more starting issues. I rode the bike a couple of months before really digging in. Replacement of all cables and bearings were the first changes. The bike is a daily commuter and I want bulletproof and never having pulled the motor apart after 15 years made me nervous so I split the cases. That process took way longer than I had planned with a variety of issues. The bike had lots of engine noise which the internet will lead you to believe this is normal. IT IS NOT! Trust me. Now she is dead smooth and silent. Below are a few common causes of engine noise.

KTM 525 Engine Noise Culprits:
Loose crankshaft nut
Bad cam chain tensioner
Bad clutch bearings
Bad rod bearings
Bad main crank bearings
Piston Slap
Skid Plate – This still makes mine sound horrible

Mine was a victim of most of the causes above. The rod and crank bearings were fine at first but when I rebuild the top end I installed the head gasket I ordered without checking to ensure the fire ring did not stick out into the cylinder. Spoiler, it was a 450 head gasket. The bike started and rod great but the noise was now worse but not crazy. It continued to increase in volume so I pulled it back apart and found the piston had turned the fire ring on the gasket into a razor blade. Round 2 rebuild begins with a replated cylinder, new 12.5/1 piston, new rod, and complete bearing replacement in the bottom end. Lesson learned. She is super quiet now.

KTM 525 Free Mods:
Cut air box cover
Cut front & rear fenders for Supermoto
Remove Return Throttle Cable

Tips for RFS owners:
1. If you hear a rattle that sounds like a chirp the throttle slide is often the culprit. Once diagnosed it can be left alone. To check, touch something against the slide while running.
2. Run your chain lose, really lose.
3. Learn to adjust your pilot fuel screw. (With the bike warm and idling turn the fuel screw in till the bike bogs. slowly back out the screw till the bike is at its highest idle and stop. That’s the amount of fuel it needs. No more and no less. In is Lean and Out is Rich. If the bike pops on deceleration try backing out a little. Could also be an exhaust leak.)
