Tiger 1050 Won't Start When Hot

Hi, hoping for some advice.

I have an 09 1050 Tiger and after riding it for an hour it will not then start, if i leave it for an hour it then starts ok. I have fitted a new battery over winter and have only had the problem this year and it seems worse on hot days. The bike has just been serviced with valve clearances done, throttle bodies synchronised etc which made no difference. It went back to the dealers who changed the crank position sensor and this made no difference. I am now wondering about the sprag clutch and is there any way to test this before getting it replaced.

Hi, it seems to turn over but doesn't fire, there is no smell of fuel but a couple of times it has fired once but not started and then doesn't fire again. When running it seems fine but just won't start after i have stopped when on a ride out. It starts great when it is at home and the problem only appears after it has been running for a while, I then leave it for a while and it starts again so very difficult to diagnose.

 

Hi, Had the bike on the diagnostics yesterday and the airbox ait temperature sensor was showing 50 degrees, obviously wrong when in a workshop. Even when air was a compressor was blown at it it only went down to 27 degrees. Did a comparison with a Tiger 800 which had been sat outside whilst mine wa sin the workshop and that was reading 27 degrees.Feely optimistic that we are heading in the right direction.
