Ive just drained the oil out of the bike, and changed the filter before jumping onto the starter chain fix
The oil filter nut was screwed into the engine so far it must have been sticking out of the petrol tank, I had to use a 3ft extension bar to remove the bolt, It went back easy enough though so fingers crossed
The starter chain fix was a nightmare as the clutch cover refused to budge without using shit loads of force to remove it, but eventually it moved and I got the kit fitted and put back onto the bike, nuts all tightened hand tight then nipped up, the kit states 87ft/lbs........not a bloody chance
Then the shit happened, I tightened the sump plug (brand new) by hand and turned it less than half a turn and its ripped all the thread out of the sump
any ideas how to fix it??
my old man suggested gluing the sump plug into the sump and drilling a hole into the sump plug to tap and add a smaller nut

this isn't the first time this has happened, (is it si ) new sumps are fairly easy to fit and cost about 130 squids part no 490341139 PAN-OIL

As long as the sump isn't cracked, then a Helicoil would be th cheapest answer. Take the sump into a local engineering firm. Probably cost £25

If the sump has to come off, I'll use JB weld to fill the hole and drill and tap that, save a fortune on a new sump then.
I knew there was a reason I'd been putting the oil change off for so long

Its quite a big hole to cover in that stuff. Could you not just build it up around the damaged thread and drill it from there? J
B weld is brilliant stuff. I know of a certain bike not a million miles from here that had a stripped exhaust manifold stud held firmly by that stuff, and despite severe thrashing hasn't shown any sign of giving up

I know of a certain bike not a million miles from here that had a stripped exhaust manifold stud held firmly by that stuff, and despite severe thrashing hasn't shown any sign of giving up I was thinking about that, but if its too thin, which it will be when its redrilled and tapped, it will just strip again Ive been researching the sump online and it seems the exhaust has to come off to remove the sump, it was a nightmare to fit, so I dont want to mess with it if possible, £130.12 for a new sump is out of my price range too at the moment. As the original sump plug only fixes on the last 12mm of the bolt, Im thinking of cutting the bolt down to that length and removing the head pretty much altogther, drilling through the centre and tapping a thread, fixing the bolt back and getting it welded to the sump, then get a smaller bolt for the new thread. That way I dont need to remove the sump, and no metal parts will enter the sump unlike they would if I used a helicoil.

ITS FIXED Yeah baby yeah My old man got a bolt at work which has a shallower head on it and only just wider than the original Didn't even need to drill the hole, tapped it in situ and let the dregs of oil clear the swarf, quick clean with a cotton bud and the bolt fits a treat, will do another oil and filter change after a few rides to fully clean the insides out.

result, now all we need to know is what size tap and bolt
