Hi,

after washing the bike down I want to drain the carb but cant get a spanner on the 17inch nut under the carb, well I can but it only moves a bit and cant then get it anymore, need a torque spanner but the one I have is too big to fit.

Is there any quick way of doing this without removing or taking things apart?

I'm pretty useless with mechanical stuff so would need to be an idiots guide :(:confused:

pics would help :D

Does it need draining after each wash or am I being a bit over cautious?
cheers
 
I've never heard of draining the carb. except for long-term storage or after a submersion. I don't think water would get past the air filter while washing the bike.
 
I have never heard of anyone needed to drain carb in a regular interval.

However, to do it you migth need to remove seat, tank, sprocket guard. Then loosen the two hose clamps on intake and outlet of carb, rotate the carb clockwise (as seen from behind), to get the bottom plug and float bowl to swing out to the side to make it accessible.
 
1) It should be a simple task, maybe take the carb off once to get it 'loosened up' & then it would be easier on the bike.

2) Probably overkill on a regular basis Water CAN get through the filter if enough goes in the airbox but with a little care it shouldn't happen
 
You can also remove the air filter and install one of those plastic carb boot covers, prior to washing.
 
Excellent, cheers everyone.
Looks like I'm overly concerned.
At the moment when washing I take the seat off/air filter and put one of those bungs to stop water then jet wash bike including the air box etc. Like to keep it clean in there :)

dry, fresh filter, then start for a few mins to get warm. Spray with gt85 then I'm ready for the next ride.

Will stop worrying now :D

dont use the universal acerbis one as it doesn't stop water/mud ingress that well, buy a proper twinair one if you can find one, if you get mud in the carby dont touch the throttle and vacuum it out, then and out of the airbox, when completely clean open the throttle and vacuum for a short period. dont think that stuffing a rag in the airbox is perfect insurance, always check to see no muddy water drained down near the carby.
 
Thanks. Yes I've got the twin air one already and seem pretty good, also stick a rag in there as well.
 
Close the petcock and turn the bike on...

I been lucky with Acerbis rubber "thing".
 
I drain my carbs while they sit in the garage. I noticed that the new ethanol gas turns to crap pretty quickly, within a few weeks the gas in the float bowl turns a dark piss yellow. I usually start the bike with the petcock off to burn off as much as possible and sometimes I have to loosen the clamps to turn the carb at an angle to get the the drain.
The 4stroke carbs are much easier. they have a drain screw on the side. Why can't the 2T's have that.

Will try the starting with the gas off for the moment. The good thing it that since Ive bought the bike it's never been sitting there that long :) any excuse to "just getting used to the new nasty 2 stroke dear, will need oh well at least another 6 weeks" :)

Yes agree re 4 strokes. I'm used to that way so was surprised to see it wasnt that easy on the 2.
 
Draining Carb

I carry a bicycle cone wrench in case I need to drain the carb on my '08 300.
It's a Park Tool DCW-3 available at your local bike shop. It's a quality tool less than 2 mm thick. Weighs next to nothing, is heat treated & nickle plated & can be bent or altered for better access. I can loosen the 17 mm drain from the rear of the bike without removing or loosening any other parts.
 
A quick way you can do it is lean the bike over on its side with the fuel on to flush the bowl or turn fuel off to drain bowl
