Hi all I bought a second hand 2008 CB400 Revo which appears to still sparkle even with its 2008 plate. The engine still had a nice pur and doesnt rattle or make funny noises when riding over speed bumps at reasonable speeds. It had 29000 km's on it and is the ABS model. I have only owned a 50cc moped (stolen from me), a 125cc racey 2stroke (melted because i treated it like a prostitute) and a 125cc naked 4stroke (which i was much nicer to) The CB400 is quite another beast. I noticed in the log book it didnt have its major service and valve clearence checks at 24000 (Instead she had a minor service). Alot of mechs said 99.9% of CB400's have good valve clearance at 24000 but I should still book her in. So I booked her in for a major service for Monday as I am planning to keep her past my P's at Lloyd Penn Motorcycles to get the situation under control. She still has alot of kick in the vtech But how hot should she be? When putting my hand on the engine it would burn me if left long enough. Is that normal? I dont remember my bikes in the UK being so hot however they were also smaller engines and that was back in the UK cold weather. After ideling the engine, letting her warm up from choke it starts to get to hot to the touch. After giving it some vtech action the engine is hot but I cant see the radiator fan spinning. The fan doesnt spin much in stop start traffic however i keep her at low revs to try and fight the heat anyway. There are no warning lights what so ever. So I ask, is the heat normal? I also wanted to know... if the valve clearance wasnt checked and out of place, does that mean the engine is borked, or is it just a bit of performance loss? What is the consequence of not checking a valve clearance that is slowly going wrong? Would it eventually have shit power or would it blow up and burn in some way? Is 6000km over the recommended valve clearance checks a major concern on the trusty CB400 Honda? Recommended check is at 24000, and im doing it at 30000 Am I worried over nothing much?
