simmsy Posted January 23, 2010 Report Share Posted January 23, 2010 (edited) I have today dropped my bike in a river and it got fully submerged under the water it continued running under water for a couple of seconds gurgled and splutterd then stopped before I had the time to pick it up. I have since managed to start it after draining the exhaust, carbureter and air box but it now runs crap. I have changed the plug air filter and checked the reads they look o.k I am currently draining the gear box oil. What to do next??

shercofray Posted January 23, 2010 Report Share Posted January 23, 2010 try taking the spark plug out and pushing the kickstart to push any water thats in the cylinder head out Quote Link to comment Share on other sites More sharing options...
dan williams Posted January 23, 2010 Report Share Posted January 23, 2010 (edited) You're probably in for a carb disassemble. Drain the carb and blow out all the orifaces, jets and internal passages. All it takes is a drop of water or fleck of dirt blocking a jet to make it run lousy. Go after the electrical connectors with WD-40 to displace any water and that includes the kill switch. The primary side of the ignition is around 400V so it doesn't take much to partially short it out. Fresh tank of gas just in case you contaminated what's in the tank. Inspect the plug wire to make sure there are no cracks leaking spark. As for the water in the engine itself it will dry out relatively quickly. The main problem that would worry me is if it was dirty water and carried dirt into the bearings of the lower end, connecting rod and piston/ring interface. Another thing that can be an issue is water blocking the exhaust though that will tend to clear itself rather quickly once the bike is started again. Good luck Edited January 23, 2010 by Dan Williams Quote Link to comment Share on other sites More sharing options...
big john Posted January 23, 2010 Report Share Posted January 23, 2010 And remember once you have done all that to get the bike up to full working temperature, run it continuosly until it gets hot fans on and off a few times!

ham2 Posted January 23, 2010 Report Share Posted January 23, 2010 (edited) ''Drowned my Rev3''...did you have no choice?was it on fire? Seriously though, like the above posts say, you've got to watch for any grit that's been carried into the engine. Water ingress is relatively easy to remedy, i got away with totally drowning my Montesa once.... You know if you leave it alone it's got grit in it... and if you strip it down... it'll be as clean as a whistle...sods law!! Could you remove the mains seals and top-end then flush everything out so you don't have to split the cases? Would you have room to leave the engine in situ?I realise the Rev3 motor is a snug ft in the frame. Edited January 23, 2010 by HAM2 Quote Link to comment Share on other sites More sharing options...
foulkesy Posted January 24, 2010 Report Share Posted January 24, 2010 Next time you decide to go up the Taff Jeff, take some scuba Gear!! WD 40 is the answer, dry her out electrics etc, clean the carb, change fuel and oil, she will be fine!! Bit of luck I will join you in a week or so once I sort this Ferkin electrical problem out. Patience is a virtue...i am told!! Regards Bubba Quote Link to comment Share on other sites More sharing options...
nzralphy Posted January 24, 2010 Report Share Posted January 24, 2010 I'd check the reeds again (disassemble them!). Water pumping into them will crack them really easily. Ralphy Quote Link to comment Share on other sites More sharing options...

02-apr Posted January 24, 2010 Report Share Posted January 24, 2010 You could be lucky or not, that's what they are saying. The one thing you have to do is get it hot today as stated by Big John or, by the time you look inside, bearings could be beyond saving due to corrosion.
