rusty chain Posted November 19, 2017 Report Share Posted November 19, 2017 Following this thread with interest as well as when riding my daughters bike today it seized :-(. Pulled top end and OK there so something down below has gone pop. I have a couple of questions:- - No trick to pulling the engine on these? Just remove skid plate front bars, swing arm bolt and anything else? - Ordering a Flywheel puller, will an air powered impact driver be OK for everything else? - Do you really need a crank case splitter for these engines? - I am thinking new gaskets, main bearings, crank seals and anything else I find iffy looking. Are there any other things routinely replaced? - Any recommendations for a one stop shop for all the bits?

huski Posted November 20, 2017 Report Share Posted November 20, 2017 Not sure the engine has seized,I'd have the clutch case off and also the clutch ,then see if the crank turns 1 Quote Link to comment Share on other sites More sharing options...
rusty chain Posted November 20, 2017 Report Share Posted November 20, 2017 Could be right there, will pull it off over the next 2 days and report back. Bike free wheeled OK, does that mean anything? Quote Link to comment Share on other sites More sharing options...
jareth Posted November 21, 2017 Report Share Posted November 21, 2017 I replaced the center case gasket in my 2012 Beta 300 with no special tools. You should be fine. Be patient. It's all about balance. Quote Link to comment Share on other sites More sharing options...
rusty chain Posted February 18, 2018 Report Share Posted February 18, 2018 update, been a while! Main bearings were toast, in the end left it in and for £100 was sorted out. Put a new piston in and all is well again! Quote Link to comment Share on other sites More sharing options...
