neils on wheels Posted March 16, 2008 Report Share Posted March 16, 2008 I recall reading a recommendation to drill a small hole in the bottom of a Beta flywheel cover a good while back. Is this still recommended & has anyone any experience to suggest whether to drill, or not to drill - that is the question? Quote Link to comment Share on other sites More sharing options...

Ooh, another can of worms Either drill a 5mm/6mm hole or cut a 1/4" 'V' out where it meets the casing... Quote Link to comment Share on other sites More sharing options...

Why would you want to do this? Surely this would allow water and other foreign material into this area Quote Link to comment Share on other sites More sharing options...
mikee Posted March 17, 2008 Report Share Posted March 17, 2008 I just take the cover off after i've power washed the bike and spray some WD40 in and around the fly wheel , and then wipe away.. leave if off while in the workshop and put back with a little sealer before i ride again. When the bikes going though a big service about every two months, i take fly wheel off and have a really good clean and then spray with a small amount of WD40. never had any worrys with mine.. Has any one tried the 2 map CDI from westcountry windings ???? Be intrested to know what there like.. Quote Link to comment Share on other sites More sharing options...
kinell Posted March 17, 2008 Report Share Posted March 17, 2008 Why would you want to do this? Surely this would allow water and other foreign material into this area "What goes up must come down." Folk spend time meticulously sealing the cover in the hope that water won't get in. However, it does get in due to the vacuum/syhponing/sucking/whatever effect but it then struggles to drain back out. Condensation can also build up... I suppose it all depends on whether you are happy to strip, dry, spray and re-seal after each trial or not - please remember that draining after the trial might not help you if you suck water in on the first section of the first lap.... If in doubt, ring John Lampkin Imports and ask them how they prepare their team bikes Quote Link to comment Share on other sites More sharing options...

atomant Posted March 17, 2008 Report Share Posted March 17, 2008 What he said above.... hole or V is the way to go.I didn't do my new bike straight away ... as i forgot!! ... but after the first ride and light wash i took the cover off to find a tide mark about 1 inch high. Now it is drilled nothing stays in there... I can't believe this. Through some fault of its design, you are happy to drill a hole in the casing to let in water and let it out again? Why doesn't it do what all the others do and keep the water out? Geez, is that asking too much? Quote Link to comment Share on other sites More sharing options...
neils on wheels Posted March 17, 2008 Author Report Share Posted March 17, 2008 The next thought that has sprung into my mind is maintenance. Do you still remove the cover & clean inside after every trial, or spray WD40 or similar inside through the hole, then just dismantle it every now & again?

neils on wheels Posted March 17, 2008 Author Report Share Posted March 17, 2008 I've just read Shirty's Gas Gas preparation tips for Scotland... Drill a 4mm hole in the bottom of the flywheel cover & refit with silicone, I can't believe this.

eddie_lejeune Posted March 18, 2008 Report Share Posted March 18, 2008 Take the cover off when the bike is new and seal it up, i have had 11 betas and no prbs with one of them once this is done they are sorted, why would you want to start cutting v's or drilling holes Quote Link to comment Share on other sites More sharing options...
bugsy25 Posted April 1, 2008 Report Share Posted April 1, 2008 just bought a send hand tidy Techno but after reading this checked the cover, not a problem with this but the breather pipe between casings that runs under the clutch banjo had worn through and was collecting water mud and all sorts, might pay to check early models as it looks like it has rubbed a hole in it, B&Q do a good selection of plastic piping to replace rather than expensive oe part.

fuma Posted April 1, 2008 Report Share Posted April 1, 2008 I would just remove the cover after washing the bike or getting it really wet. It is 3 allen bolts and takes all of 5 minutes to remove and spray it out with WD40 and compressed air. I remove mine every so often just to be safe.

copemech Posted April 2, 2008 Report Share Posted April 2, 2008 Well, that makes a few i can count now! And from ALL with the plastic covers i think! You simply cannot trust them to seal because they flex, primarily. Even a metal cover is not absolute in its abiliy to seal against a pressure wash. And you probably do not want to know what they cost when you bang them anyway. Can Shirty(Gas), R2W(Bet), and meself(She) all be totally off the wacker on this, I doubt it, although I normally settle for a 2-3mm hole as I like mine a little tighter! Go figure!

nif40 Posted April 3, 2008 Report Share Posted April 3, 2008 DO NOT PUT A HOLE IN YOUR FLYWHEEL OR NOTCH OR ANY TYPE OF EXPOSED HOLE.........THIS IS NOT PROPER. If someone can tell me how to post a picture on this site I will show you how to remedy this issue. The solution is simple, cost almost nothing and you will not have any worries with water getting into the flywheel area. Items Needed: Clear tubing (4 feet long) shrader valve Drill & Tap Quote Link to comment Share on other sites More sharing options...

And I have seen them plenty full of S%%T! Quote Link to comment Share on other sites More sharing options...
