lineaway Posted March 20, 2018 Report Share Posted March 20, 2018 If it looks like a lower case bolt, that is also the drain. Quote Link to comment Share on other sites More sharing options...
section swept Posted March 21, 2018 Report Share Posted March 21, 2018 Drain plug on a Bultaco should be in middle half of timing side crankcase. Bash plate usually has a hole for access. Quote Link to comment Share on other sites More sharing options...
pmk Posted March 21, 2018 Report Share Posted March 21, 2018 (edited) I believe, and can check next time I drain the oil, that is a second drain plug. If the Scorpa had a left side kickstand, you could remove that drain while on the kickstand, rather than use the lower one where the bike must be vertical to drain the oil. The parts manual shows it simply as a straight bolt / plug. No special detent or anything, just a plug.

section swept Posted March 21, 2018 Report Share Posted March 21, 2018 (edited) On the clutch case there is a bolt that has a slightly larger head to it, this is to grain the clutch oil. My photo shows the gearbox drain plug. Detent plunger boss is shown left of pic. Edited March 21, 2018 by section swept Quote Link to comment Share on other sites More sharing options...

The drain on the Scorpa SY250 he is referencing, is nothing like a standard case bolt. Case bolts are typical Allen head style, while the drain is a hex head bolt style with built in flange to help seal the copper washer.

lineaway Posted March 22, 2018 Report Share Posted March 22, 2018 He asked about a Scorpa, not a 25 year old Yamaha. I thought maybe he updated. 1 Quote Link to comment Share on other sites More sharing options...

Agree, but Bondy does have about half a million very recent posts about that old Yamaha engine in the French chassis. Besides, is a modern Scorpa still truly a Scorpa, or rather a Sherco with different paint? He certainly did not ask about Shercos or their granddads, the Bultaco. 1 Quote Link to comment Share on other sites More sharing options...
lineaway Posted March 22, 2018 Report Share Posted March 22, 2018 Being they never had an engine of their own till now it is hard to say. But Scorpa today is doing well. More popular than ever. Quote Link to comment Share on other sites More sharing options...
