nicbrrghs Posted December 2, 2011 Report Share Posted December 2, 2011 Someone out there must know a good way of sealing the flywheel cover up to keep the dreaded water out. My bike suffers even when its jetwashed and always seems to need cover taken off and dried out. The stator needs cleaning because it rusts over. Its a rev3 270 2003 ANY IDEAS!!!! Thanks in advance Quote Link to comment Share on other sites More sharing options...
sfield Posted December 2, 2011 Report Share Posted December 2, 2011 Not found a way to keep water out of a Beta, Gas Gas and now Ossa. Take it off every time dry and WD40, replace when preping to go out again. No better way. Quote Link to comment Share on other sites More sharing options...
b40rt Posted December 2, 2011 Report Share Posted December 2, 2011 Sanitary silicon is a good sealant. Personally I never pressure wash anything. Quote Link to comment Share on other sites More sharing options...
eddie_lejeune Posted December 2, 2011 Report Share Posted December 2, 2011 Seal it up with an instant gasket type stuff but dont put too much on as it will get in around the flywheel. Let it harden properly and you wont need to take it off again. I have had a new Beta every year between 1996 and 2010 and done this with them all and never had a problem with them Quote Link to comment Share on other sites More sharing options...
twinkletoes Posted December 2, 2011 Report Share Posted December 2, 2011 basically you are never going to seal it up properly, its is nigh on impossible, just let the water in and let it back out, loosen off the cover after washing, pump the wd40 in as the man says and let it dry off. tighen up next time and away you go.....

steam Posted December 2, 2011 Report Share Posted December 2, 2011 do you have to remove the flywheel Quote Link to comment Share on other sites More sharing options...
pindie Posted December 2, 2011 Report Share Posted December 2, 2011 No! Just air it out. Make sure you do not tighten to tight and stop it mating properly. On a clean and dry motor you can smear vaseline around the joint. As the engine get warm the vaseline melts and capillary action pulls it into the tiniest of crevices. (my wife is not called capillary!). This trick also works on bulbs for rear lights etc. No moisture ever gets in where vaseline goes when warm.

overdale Posted December 3, 2011 Report Share Posted December 3, 2011 I have had Betas for years and the cover is definitely not designed to be watertight so water will usually get in, but because of the fit of it, it also can get out! Obviously, if your stator and flywheel is full of muck and rust you'll have to take the flywheel off and give it a good clean then lightly spray with WD40. Make sue that the taper is clean and dry before you assemble. Providing that the cover is not damaged or distorted, refit the cover without any sealant. After every wet event, practice or wash, remove the flywheel cover and leave the bike with a lean to the right to allow any water to run out. Wipe as much of the outside of the flywheel as you can, blow out with air and leave to dry as long as possible. Spray lightly with WD40.

stecks Posted December 3, 2011 Report Share Posted December 3, 2011 ...it is a long time ago now, but I seem to recall that the OSSA had an application of what looked like clear silicone - was that available when OSSA first appeared...??? at the rear end of the flywheel cover, presumably to stop water ingress from the spinning drive sprocket? I also recall cutting a small vee in the bottom of the flywheel side cover to let the water out - it seemed impossible to stop it getting in...

barcota Posted December 3, 2011 Report Share Posted December 3, 2011 Use of any sealant with a silicon base is not a good practice. Silicon promotes the oxidation of aluminum. This also holds true when used on rims to eliminate leaks. Quote Link to comment Share on other sites More sharing options...

This also holds true when used on rims to eliminate leaks. Some cheap silicon has water content, more expensive has acetone, I have used silicon on my B40 primary chain case for many years, and cant say I have noticed oxidization in the that area.

neilnh Posted December 4, 2011 Report Share Posted December 4, 2011 Instant gasket works fine for me and havent got any sign of rust on my 4t since changing the stator in may Quote Link to comment Share on other sites More sharing options...
wonder boy Posted December 6, 2011 Report Share Posted December 6, 2011 (edited) Drill a tiny little hole from the inside out on the cover at the bottom ( 2 or 3mm ). But you need to sit the bike flat or leave it leaning against a wall to the right. At the stand is on the left it wouldn't let any water out that is in there. All the local lads do this to there bikes and also during the SSDT. Edited December 6, 2011 by Wonder Boy Quote Link to comment Share on other sites More sharing options...
nicbrrghs Posted December 6, 2011 Author Report Share Posted December 6, 2011 I have sealed it now but the idea of a small drain hole sounds good. Thanks for all the advice,perhaps it should have been designed correctly to start with lol. Quote Link to comment Share on other sites More sharing options...
