Took my KTM to the track on the weekend and it handled great. Can't say enough good things about how well the stock suspension (forks/shock) worked with the Pierelli Super Corsas. However, the power was just not there. The bike had no power and farted/backfired when rev'd hard. I only saw 89 KPH as top speed where I should have seen around 160+KPH. My KTM has stock air filter and air inlet tube, F1 exhaust can and I ran 100 octane leaded Avgas (I use it in our endurance race bike). No other engine mods. No Akro update to the ECU either. Track opinions are that the fix is to replace the leaded fuel with street 91 octane unleaded fuel and add a PCV. Suggestions? parillaguy
