Haven't had to find that out the hard way, so thanks for that woody. So what can we do? Write to Aprilia and ask for a better tool kit? Feck, We used a mates kit from his '98 Blade once when another mates Zuke broke down. I swear you could have taken the engine down to the cases with that tool kit. Why couldn't Aprilia make a kit that could at least help the owner when there was minor maintenance to be done. Then again, there isn't much room there under the tail, is there?
