Rain stops play?
Permalink  
 

I rode the TTR to work today and she ran perfectly. I left her parked in the rain for 8 hours. When I started her up to come home, she just didn't want to run. I managed to limp about 1/4 mile, sometimes running fine, then bogging and stalling. Next only running with the choke full out before stalling again?

Whilst waiting for the AA in the rain & 80mph winds, I started her up and let her idle for 2-3 minutes. If I pulled the choke on she flooded & stalled. I started her up again straight away and the opposite happened she would only run with the choke out and stalled as soon as I pushed the choke in?

I won't get chance to have a look at her until the weekend, so any suggestion or theories before then would be appreciated.

Dirt or water blocking the pilot jet?

I think I'll drain the petrol into a couple of clear bottles and see if I can see some water in it before I pull the carb off.

If it comes good once dry  might pay to check the kill switch if they have dust that's damp it can muck around with the quality of the spark 

Bit common but getting wet sets it off with

Well I had a quick play this afternoon and I'm none the wiser. The bike was still lumpy & bumpy when I started her up.

I drained the tank a pint at a time into a milk bottle and that looked clear. Apart from a couple of tiny, tiny water drops.

I got the carb off and blew through all the jets with a can of compressed air, but they all looked pretty clean anyway. The screws showed signs of previous butchery but the internals look ok.

It was starting to get cold & dark so I connected the carb back up and tried starting her up without the air-box re-installed. She started, idled and rev'd like there was nothing wrong. I didn't fancy a test ride with no seat and the electrics hanging around the shock, so I'll see if the apparent fix is still extant tomorrow.
