My dad has a ktm 400 wich recently had the following happen. A nut and bolt fell somewhere into his engine and they found the nut but not he bolt. We recently took apart the whole engine to find that there was no bolt. We did not decide to split the cas though because my dad did not know if it was worth it or if he wanted a big bore kit. ANy advice on what you think we should do, and is the 450 big bore kit woth it.
