KTM 950(LC8) Canisterectomy

There's lots of variations of the Canisterectomy, mainly because there are a lot of variations of the Canister. The parts used and the method the factory used varies from year to year, and even from country to country in a single year. Lets not blame KTM for this one. They are just trying to meet the requirements of an eclectic bundle of emissions standards worldwide. Lets all remember, the bike ran fine as originally designed by the engineers in Mattighofen. Once we get this "add-on" crap off the big Katoom, it will run, once again, as designed.

Now, a couple of points:

1. The original LC8 carbs were vented with two (2) separate lines directly out the bottom of the air box. The front carb was 275mm(10.8") long. The rear carb was 250mm(9.8") long. No filter, "Y", or any other device was attached to these vents. The carbs were tuned by the factory to work with this configuration. They can be tuned to work with just about any other configuration, but why bother. Simple is usually best.

2. Carbs (especially CV carbs) inside airboxes, like the KTM 950, are notorious for being sensitive to float bowl venting. The 950 exhibits this as a part throttle miss. There's a good reference to this phenomonon by Factory Pro dyno tuner Marc Salvisbergover at their website

3. The original Desert racer LC8's vent each tank individually with hoses running straight down the sides of the radiator to just above the bottom of the tanks. No filters, "Y", or any other devices are attached to these vents.

4. The original Desert racer LC8's did not have EPC valves or an SLS/SAS system. Nor did it have CATs.

So, it would be a good start toward getting any LC8 to run as it was originally designed to run, by removing all of the add on crap and return it to as near as possible to the original spec.

I know lots of folks have done it differently, and lots have had success with their methods. Some have not. That's fine. I'm just stating an alternative to all of the various designs. A single, simple, back to the basics solution that has worked for me.

Also, please folks, don't try this at home. Leave dangerous procedures to the expert professionals. Also this modification is not approved by the EPA, EUC, or the NBA. So only use these "modified" vehicles for off highway, closed course, racing activities. YMMV. Yada, yada, yada...
