Two stroke tech tip, but it also applies to really anything with a fuel system that relies on vacuum and/or gravity to work. Before doing any jetting, fuel tuning, or troubleshooting air/fuel related running issues, you MUST make sure your engine and fuel system are leak free!! Had a small leak around the fuel inlet when I started adjusting the brass on the 500, and while minor, it will impact the jetting!! Anywhere fuel can leak out, air can get in thanks to the vacuum from the engine pulling on the system. Anywhere fuel fuel touches between the petcock and the piston, if you have a leak your engine can lean itself out! Two strokes have an additional air leak point that 4 strokes don’t in the ignition side crank seal because the fuel charge goes in the crank cavity before going into the cylinder. If you suddenly have to change and chase jetting and nothing about the bike has changed and the weather is relatively consistent, you aren’t chasing jetting; you’re chasing a leak!! *Not pictured is the zip ties I cut off already that I prefer to use over the stupid OEM spring clips and worm gear clamps; they seal better and are far easier to use!*

Got the new carb and reeds stuffed in the ole pig, and it fits far better than the original KX500 carb did! Doesn’t look homemade anymore, even though it is a bit cramped being an old Kawasaki 500 2 stroke stuffed in a modern KTM 450 frame. 38mm short body Keihin out of a 2000s KTM did the trick! Coming soon is a video reveal of the complete bike with a few pictures showing the little details that were changed/updated over the off-season. Aside from a few more titanium nuts and bolts here and there, this bike is finally completely done and looks exactly how I pictured it when I started the project a few years back!! 🤘🏼🥹

Nobody makes the part you need? Well, that just means you have to make it! Made a new pipe up for the 2015 KTM 500SX-K, and it was a project! Over 24 hours into the fabrication and welding, but that’s what it takes sometimes when you want things to look like not s**t! Started out with a brand new Pro Circuit Works CR500AF pipe, then proceeded to do what I needed to do to make it fit where and how I wanted. All work done in-house! Sometimes quicker isn’t better, even if it means spending more. When you rush things, you miss little details or execute things in less than ideal ways. I wanted this pipe to look like it came from Pro Circuit the way it sits on the bike, and I think I managed to pull that off! Need your bike built? Give us a shout! We do it all, from routine maintenance to all-out builds!! Just waiting on a couple bolts to show up from Racetech Titanium and new exhaust springs, and I’ll get some pictures of the completed pipe on the bike for the world to see. There’s a couple trick little details that’ll accompany the pipe that you’ll just have to wait to see!!

CR500AF pipe turning into a KX500/KTM pipe. Fully customized. 🤘🏼

Switching up the induction a little bit on the 2015 KTM 500 SX-K to get things fitting a little nicer and looking more like it was built like that at the factory. Going from the stock KX500 long body PWK39 to a KTM PWK38S short body. Making that change allows me to use an unmodified air boot from a 2015 250SX with no clearance issues around the shock whatsoever. Only thing is that the angle is a little different than the 250SX from the boot to the reeds, so I’m going to let it sit assembled like this for a couple days and then hit the air boot with a heat gun to give the air boot a new “memory” for its new home. Not pictured is another factory-spec style change I made in switching from the KX500 throttle assembly to a KTM Domino throttle assembly, so all my main bikes will now use the same throttle parts and lock-on grips. More updates to come, as I’m also going to be reworking the pipe and cooling system to allow for better fit and finish than the initial ex*****on I went with, as well as a couple other little tweaks I’ll be making to the induction system!

When you know what you need but nobody makes what you need, you simply make what you need!! More updates coming soon to the 2015 KTM 500SX-K to make it look and function even better! *Disclosure notice: Orange KTM pipe collars prior to modification made by , not myself.*

If this picture doesn’t invoke in you feelings of PTSD, nausea, or the sudden desire to procrastinate horrifically, your winter cleaning isn’t good enough and you need to do better for your precious!! 🤘🏼🤘🏼

This right here is what properly a greased linkage look like! CMD Extreme Pressure Grease on the rollers and Royal Purple synthetic grease packed in the seals. A little preventative maintenance goes a long way!!

If this isn’t what your winter maintenance and brand new bike prep looks like, then you need to step up your game!! Tear it all down, clean it all up, and use high quality greases!! Yellow tube there is the single best suspension grease I’ve found, and it’s worth its weight in gold, bc I’ve yet to have to replace any bearings since switching. I use this stuff on linkage/swingarm bearings, steering stem bearings, wheel bearings on everything but 125s, and in the motor as an assembly l**e in certain locations as it’s oil soluble and won’t foul clutch plates. Take the necessary steps and you’ll have a 100+ hour bike looking and performing like a 30 hour bike!

A little bit of maintenance and additional bling to get some extra horsepower for my 2016 Husqvarna TC250. Work schedule is a little heavy right now, so it’s not quite time to do the full teardown and winter maintenance yet, but I’ll get started on that next weekend and show you the things that need to be done to every bike (yes, even your brand new bike you just got fron the dealer yesterday) to make sure it stays shiny side up! Got 3 bikes that need winter maintenance, an 86 Honda CR250 restomod, and a street build to do for Gettysburg bike week next year, so time to get cracking! If you want your bike squared away and ready to go for next season but don’t have the time or motivation to do it yourself, give us a shout!! *we don’t charge your typical shop rates because this isn’t our 9-5, so expect to pay less and have your bike treated like it’s our own!*

Little late season lunch ride, followed up with getting a start on returning a 1983 GL500 back to the road after sitting for 20+ years. She’s gonna need a little bit of help, but she’s nowhere near hopeless! We don’t just do 2 strokes!! 🤙🏼
