Petrol Petrol everywhere........
Petrol Petrol everywhere........
Hi, due to work and laziness, my VTR has sat in the garage these past 3 years completely unused. I got the bike out last week, in the hope of a quick MOT and a little bit of summer. Brand new battery, brand new fuel, brand new oil........and no go. Looked like fuel starvation, so removed the vacuum tap from the tank, gave it a good going over, and now it's working fine. Gave everything a blast of carb clean. Now she starts.......but misfires like a bugger.....but more worryingly, she pisses fuel out the overflow pipes from the carbs. At first, she was doing this only when I turned her off, but now she does it all the time. I'm thinking sticking floats in the carbs, but want to avoid removal if I can. Am I on the right track? Is there anyway I can solve the problem without removing the carbs?

Hi Bump
Welcome Aboard
Alas you are completely right. The only way for the carb to overflow is if the floats arn't returning the valve back into its seat.
You might try just letting them soak in some carb cleaner but if that doesn't work you'll have to remove them.

Hiya matey,
Take a look at this recent thread.
http://www.vtr1000.org/phpBB2/viewtopic.php?t=11581
I'm having similar problems with Gixxer ATM so much so, the engine's full of fuel too
Hopefully I'll get them sorted this weekend. A partial strip and check of the needle valves and float heights.
Just in case, I managed to win a 'spare' set of carbs on flebay last night nice and cheap, so if all else fails, will just swap the lot.
If you do strip the carbs though, pay very very careful attention to the needle valve and seat. The slightest ring or mishape on the cone of the needle valve can cause it to not seal correctly. Any scratches pits or ridges on the brass seat can cause same.
If possible, check if only one is flooding before removing them (after can be done too). Then you know which needs your attention.
To do this you can lift the slide and peer into the carb to see if it's overflowing or not. To do this off the bike, an auxilliary fuek tank or lash up can be used but ideally you want to have the carbs over a container to catch fuel overflow, also carbs ideally need to be 'propped' in same position / orientation as they would be on the bike.
*nb* once sorted, an oil and filter change might be advisable.

Good clean up and spray with proprierty carb cleaner should sort it. Usually three year old unleaded fuel will gum all the jets so surprised it worked at all!!!!
Mowers suffer hugely after one winter of non use (and a summer of abuse!) with these problems. It is probably just the fact that the VTR uses such fcukin huge carbs and jets that allowed it to function in the first place.
Next layoff use this in the tank and run the carbs dry by disconnecting the fuel pipes!!!

You don't need to disconnect the fuel pipes, just the little one that goes on the rear of the fuel tap- it's a vacuum line that turns the tap off when disconnected.
If you've got a scottoiler fitted you can get to it really easily.
Just break the vacuum when the bike's running and leave it ticking over- it'll run out in a couple of minutes.

It's not falling off, it's an upgrade opportunity.
