Hard to start after a soaking
Permalink  
 

I picked up this well used TTR on Sunday and had a fantastic day out with the Herts TRF today in the torrential rain, great fun!

The bike performed well but after running through some heavy puddles and getting a good soaking the bike would die as soon as I stopped and then be very hard to get started again, taking a dozen attempts at least, eventually running with the choke on.

After 5/10 minutes of riding the bike would be fine again, so I suspect it's not electrical because I'd be surprised if it would dry that quickly, so maybe water being drawn into the carb.

Any suggestions as to things I should check out tomorrow, anything obvious to suggest? There were lots of grumblings about breather tubes and stuff from others so any pointers on that might be useful!

Thanks!

Ben

The breather pipes are suppose to have serviceable one way valves on the end so yeah check that. Make sure the breather pipes are there in the first place I spose!

Welcome to the forum, Ben. smile

You would also be well advised to check ALL the wiring connectors you can find.

They are found behind/inside the headlamp, handlebar switching, steering head, under the tank, under the saddle, down each side of the frame and connected to all the switches and units.

Dismantle them, clean the crud off, WD40 them and reassemble - one by one.

A waterlogged side stand switch or neutral switch can cause ignition problems - don't ask how I know. biggrinno

Hi Ben

 

we certainly did have a good day. Very wet out there today  

 

As as I mentioned in the past I had problems with other bikes and breather pipes.   Never had a problem with my TTR    Is the HT lead in good condition?

Hi Ben and welcome to the forum!

Having to use the choke to restart tends to point to water in the float bowl.

Put a cloth under the carb to catch the petrol and open up the drain screw at the bottom of the float bowl using a well-fitting screwdriver to prevent rounding it off! You can usually spot any water coming out as it will appear as droplets or globules.

If there is water then you will need to check that the airbox and the pipe between it and the carb are all watertight. If it is then you will need to check the breather pipes that drop down from either side of the carb have working one-way valves on them. A quick blow/suck will soon identify any problems wink

Well one of the pipes has a working valve so I have tucked the other up into the top of the bike for now until a new valve comes. Thanks for the suggestion Paul. The HT looks good too, but I suppose you can never really tell. 

The drain screw was rounded off, so removed it using a screw extractor thinking I could replace it with a Allen head bolt but of course it's a special shape! Stuck it back in for now.

The main problem is the massive crack in the airbox cover expertly gaffer taped up, I'll have to get a new cover sorted too. There was a fair amount of water in the airbox and I bet some got through as the filter was slightly damp too.

Off to spend some money I think!
