Hey ladies and gents. I’ve purchased a bargain of a 990 SuperDuke to pair nicely with the F800GS but as with all bargains..... there’s a hitch. my mates recommended this site and another to see what others think. Please don’t kill me by abuse if I’ve committed forum crime but not having a 990 adventure problem :) The guy a got it off had stalling issues and had replaced the water pump axel seal etc which he said solved the problem for 80km then it came back again and kept stalling. He then left the bike sitting for a few weeks and decided to shift it on, person turned up and jump started the motor with cables. Went dead again. I bring it home and having paid for it discover the motor is locked up. Starter trying but engine not moving. panic. Seized I thought (still think) but...... I popped the air box and plugs off. Looking into the front cylinder I see open valves and some fluid down there. done the 6th gear reverse (by myself) and it won’t budge. I’m hoping it is hydrolock and I need some tips on get it turning? How hard do you need to push? Is it likely to break? Could the guy of knackered it trying to start it via jump leads?
