Been riding my newly built bike for short trips breaking in the engine. So far after about twenty miles all is well. It does appear the chain may need some thighting etc. The main question here put to the old and young timmers here is the following. The engine upon shut dowm seems to put off a hot smell. Not alarming but none the less seem like the engine is hot. Is this normal on a new run in? I would think yes but would like to be sure. Had to turn down the idle today so must be getting looser. Thanks for you time and shoot a response if you can. Thanks. gphil
