Snapped head of transmission level screw

[Cajun]

I wonder who would know better... the factory that wrote the manual, or the yobs at some NZ motorcycle store... hmmmm... Go search/ask on rgv250.co.uk

and some yobs on a bike forum would know any better?

Stick with the manual says

Yep, even if it's a manual for a 2-yrs newer model, it's still basically the RGV250 engine, no? They wouldn't change the gearbox that drastically to require a completely different weight oil.

I've had a search on RGV250.co.uk and there doesn't seem to be an agreement about the weight of oil. They are saying not to use fully synthetic as it can cause clutch slippage.

I have had luck with using epoxy to glue an old screwdriver to the snapped screw. The plus side is that you get the screw out or it just doesn't stick hard enough and comes off. Engineers and the like don't normally mind fixing stuff for you but if you carry on and totally fuck it the sympathy seems to run out fairly fast. PM me for a ride bro, sounds like I'm near to you. I have weekdays/weekends free at the moment.
