Sip77 Report post Posted February 24, 2019 Anybody know if this hole is meant to be here? Doesn't look like it to me? will it be a problem or will it need sorting? Quote Share this post Link to post Share on other sites
technowaldo Report post Posted February 25, 2019 Think it’s just part of the casting if there’s no aluminium debris in the oil just forget about it Quote Share this post Link to post Share on other sites
Sip77 Report post Posted February 25, 2019 The oil was a grey green colour but not seen any debris. I'll stick it back together and change oil again see what it looks like. Thanks. Quote Share this post Link to post Share on other sites
the dabster Report post Posted February 25, 2019 Gasgas is identical it allows the oil to transfer through clutch back to gearbox in the gasser never seen the inside of a beta but would imagine identical role unless I'm wrong of course! It's a pretty big coincidence I think it's meant to be there. Quote Share this post Link to post Share on other sites
markparrish Report post Posted February 25, 2019 Yes - I thought that when I saw a similar hole in my Rev 3!! - It appears to be deliberate, but has a very rough and broken "aesthetic"! - maybe they do it during the casting phase? Quote Share this post Link to post Share on other sites

dan williams Report post Posted February 25, 2019 If you look at the 2017-2018 engine service manual it looks like these are intentional oil passages. https://www.betausa.com/sites/default/files/pdf/trialsservicemanuals/2017-2018 Evo 2 stroke engine service manual .pdf Quote Share this post Link to post Share on other sites

billyt Report post Posted February 26, 2019 (edited) SIP (SNP?) What year is the Beta? If the gasket has a corresponding hole then it was that way from the factory. I think it may be a dowel pin hole for aligning the first outer case! If so then you are missing dowel pin.... Is it hollow? The picture is fuzzy it even looks like the head of a screw has broken off. Does the matching case cover have a locating hole also?

collyolly Report post Posted February 26, 2019 billyt, I think he is looking at the big hole through to the gearbox,( you can see the gears), you are looking at the fixing hole on the gasket line ? Quote Share this post Link to post Share on other sites

Sip77 Report post Posted February 26, 2019 Yes it's the big hole. The casing feels very thin around the hole and it is rough around the edges. Like it's been hit with a hammer. Maybe an end of day casing when the tools have been dropped! Quote Share this post Link to post Share on other sites
