I'm a fucking idiot!

[awayatc]

done similar stupid shit myself, and not trying to be smart....
Torque wrench one option.....
Using right size tool for job also helpfull...
hard to wreck things with fitting ringspanner for example.
Good luck, know how you feel.

I just managed to overtighten one of the two oil drain plugs on my ninja. The one leading straight into the case,

Now... ideas for what to do, it doesn't need 2 draining plugs, so... should I just put a new bolt/washer into the plug I've stripped and use sealant, and leave it for eternity never to be used again. Rather than the horrid replacing the engine case or boring a bigger hole just so a spare draining plug can be used.

I want to get back riding asap, and I can't believe I did something so stupid. Should have bought that torque wrench when I thought about it!

Just to clarify. Did you over tightened the bolt and the head came off leaving the thread inside the bike?

Thread inside bike is shaved. Steel bolt vs aluminium engine case.

Shit that sucks. I once over tightended a bolt and the head came right off...but this was a situation of a crappy bolt vs steel thread. It ended up being a very simple fix compared to your problem. Good luck.

Do I just drag my bike into cycletreads?

NO NO NO NO NO NO NO NO NO NO NO NO


Actually you obviously do not know what you are doing.
1, you stripped a thread on a sump plug (happens to all of us),
2, you want to fix this with sealant (DON'T),
3, you want to go to cycle treads to fix it.

This is what you have to do.

1. drain bike of oil
2. Remove sump
3. ring around the bike MECHANICS not the tyre shops and check the price for a helicoil for bringing in the sump.
4. once sump is fixed re attach.

Infact scratch all that, call george from motorcycle doctors. he is much better than cycletards.

Bad luck!

You can get helicoil kits to do the job yourself if you want, engineering suppliers will have them. Not sure if it will work out more or less expensive than getting a mechanic to do it.

Afterthought: Could you just retap the hole (cutting threads) and fit a bigger sump bolt?

HOW MANY TIMES TO I HAVE TO SAY!!!!

It's not the sump draining plug I fucked up, it's the draining plug that leads directly into the engine case, right next to the oil filter. It cannot be detached unless I detach the entire engine casing.

Botz honda just quoted me about 100 bucks to fix it, all for being too tightening happy. This is just like the time when I was 15 and kept filling up my car with more and more oil wondering why it didn't reach the brim. I don't know what my brains doing most of the time when I do anything mechanical related. It just whizzes off and I'm left with homeless harry.

do u mean the engine side cover / clutch cover?

but get a quote from motorcycle doctors first. 0800 668 663

Um, I'm not sure. It leads directly vertically from the very bottom of the bike in towards the engine, the sump is lower down and off to the side with a horizontal draining bolt.

The location of the threaded hole (a picture tells a thousand words, btw) presents another issue - that of swarf removal from any drilling and tapping (getting the metally bits out of the engine).

Call George from Motorcycle Doctors, if at least for a second opinion. From what you've described I fail to see how it could be repaired properly for $100 and would be wary of someone claiming to be able to do so.

FWIW, if you are buying a Helicoil kit you're paying primarily for the oversize tap. Kits go for upwards of $130, making for quite an expensive hole. There are also solid threaded inserts available in N.Z, they have two notches at the bottom that cut the thread on insertion. These solid inserts are available individually for around $5 although I'm not sure about size range (i.e fine pitch, etc).

You probably don't need to invest in a torque wrench, maybe consider swapping that 24" 1/2"dr strongarm for a wee 1/4"dr set instead?.

Any chance of a photo?

That should have been a clue right there.
If at first you don't succeed - give up.
