vapour lock anyone?
The only problem I've had with my 450 foreman is the vent hose in the gas cap plugged (the hole it goes into filled with water) and eventually airlocked stumbling the motor. Once I realises what it was I popped off the hose, blew it out and let it hang over the bars for the rest of the trip problem free.
Is your temperature light comming on or do you have a temperature light. Maybe theres a safety temp swithch that kills the motor when it gets too hot (which would be a real poor design). I ran my foreman this past weekend with a full load on the racks, 2 people and towing a steel trailer full of camping gear in 30 degree celcius heat with no breakdowns, the fan was on alot but temp light never came on. |

hey i own a new 420 honda and have had a bunch of trouble with it vapour locking when i work it hard at slow speeds i was just wondering if anyone has had a similar problem my dealer cant find anything wrong with it and yet every time i run it in say first gear over tough terrain for an extended period the engine starts to lean out and stops running if i shut it off and let it cool for awhile it runs again strange eh anyhow if you own a 420 maybe you could do me a favour and put it through a little test just so i know if it is just my quad or if honda needs to redesign there fuel delivery system a bit. to test do it on a warm day let it get warmed up by idleing or riding it around normaly then shift it into first gear and drive it slowly with a load on the engine a hill works great my quad will vapour lock within 15 minutes under these conditions none of the indicator lights have ever lighted on my bike good luck

hms45in has a different bike to you. Different fuel tank, and totally different fuel injection system. The first thing to do with any EFI problem is to fit a new fuel filter. Check that the tank vent isn't blocked, and hope you have fixed it. May be a good idea to treat it to a new plug too. It is under warranty, so you should give the dealer the headaches anyway.
