STOP! Please step away from the drill

even though the work to repair the thread will now iam sure be done properly you have to consider how the insert was put in before and as already mentioned the tag must have gone somewhere i would want that motor stripped for peace of mind so no shortcuts for this job, its not overkill the amount of work mentioned to fix this issue, always the same i find when you have to rectify a previous bodge
 
Just to play devils advocate,
If you stripped the sump plug on your engine,gearbox or anything else,
Then took it to your local bike shop or garage and they repaired it in the same way as this had been done,
Would you be happy to have oil dripping all over the shop or would you take it back and expect them to rectify it properly?
I’d love to be a fly on the wall for some of those conversations:D

It's why i saw the attempted repair and didn't want to get involved ;)..

Give my love to Sudi, a very decent chap. .

I would mill up that hole to the smallest diameter you can get it to be straight and clean, then measure.

Plugs are available in M18x1,5, M20x1,5 and M22x1,5 as a quick search reveals.
The hole needs to be 16,5, 18,5 or 20,5 mm for the required plug.

To tap that hole without disturbing the baffle too much, start with a normal tap, go in as deep as you can, remove tap and grind away the taper from said tap and go in again, takes some doing, but sure beats the welding, insert, or any other bodge.

Just my 2 cents. :D:

I think a lot of readers are perhaps missing a very important point here.
Whatever method is used to repair the crankcase it is vital that there is no risk of swarf getting inside the engine.
there is no guarantee of this ,apart from doing the work on a bare crankcase.
If I were to drill and helicoil in situ and engine damage occurred,I would soon find myself in a small claims court facing a very hefty repair bill.
So in some cases(this being one of them)
I’m not prepared to accept the exposure to risk,
So it’s done properly or not at all:comfort

I agree with the sentiment about doing things properly but then I wouldn't be using a helicoil to repair a sump. My view is that they might be OK for things like cylinder head studs (not bolts) that hopefully will stay in place, the are not the best solution for things like spark plugs or sump plugs. I spent 30 years fixing Citroen cars and in that time I ,or my staff, dealt with a few cases of stripped threads in the sump. Usually we only found the problem when we attempted to drain oil. Occasionally someone would own up to having done it but that was rare. I always used a Wurth Timesert as these are designed for applications where the fastener (in this case a sump plug) need to be repeatedly removed and refitted. Most of these cases were on 2CVs, I think because being cheap (at that time) they were more prone to the tender mercies of ham fisted amateurs. On a 2CV the sump plug has the same thread as the spark plugs so my much used cylinder head repair Timeserts fitted here too. As with the heads these were done in situ. Plenty of sticky grease on the cutting tools catches the swarf. There is no chunk of steel to snap off as with a helicoil. A Timesert, if fitted correctly, stays in place. In all those years I never had a problem with engine damage, many of these vehicles kept coming back for servicing for years afterwards.

I respect your views (and am in awe of some of your work) but in the case of the engines I was working on it would have been cheaper to fit an exchange engine from Citroen than to charge for the work of stripping and rebuilding an engine. Vehicles with a bolt on sump are, of course,a different matter.

Dident mean to sound quite so silly but all the expence of time and effort there surely must be a cheaper way.

There is, sell the bike to someone else and buy another without the problem :D

Thankfully the owner is being generous and keeping Mikeyboy out of a cardboard house in the doorway of Waitrose.

:agree:agree
Anyway,it gives us a good opportunity to deal with other issues :thumb

Ah yes, the joys of using a phone to view images.......... That is truly horrific, must be an R1200 that's done over 10,000 miles :D

Bare in mind that bike has been ridden to morocco and India and back over the last two years.
 
When does the therapeutic feeling of achievement bringing that up to sparkly state 1, become "OH FFS, will this shit never end?"
