Bike stops running when hot
Posted: Sat Jul 20, 2013 12:23 pm
First of all, I'm not sure what the problem is so sorry if this happens to end up in the wrong forum......
So, rode the bike to the garage on Thursday, went fine, sailed through its mot, when I went to leave it wouldn't run. Now this isn't the first time this has happened, allow me to explain....
Its a 1988 Kawasaki ZX400G Jap Import
Its just finished a 3 month strip down and rebuild
Bike runs fine until the temp gauge gets to half way (it never goes further than that, never over heats)
Then it will cut out, and the only way you can start it is on full throttle (but the revs never go above 1200) You also need to keep it on full throttle to stop it cutting out (release the throttle, bike dies)
Now, I have two thought. Either its something to do with the bike getting up to temperature - maybe something expands and blocks fuel or air.
Or, it could just be a coincidence that it runs for teh length of time it takes to get warm and be unrelated to the temperature of the bike. For instance, if fuel runs out in the float bowls after 10 minutes of riding, the bike will be up to temp but the carbs have run dry
After its been left for a few hours (usually overnight) it starts up with no problems
Now, I'm fairly new to biking but pretty handy with a spanner so anything you could offer as advice or suggestions to check I would be very grateful
Thanks
