Roo's Viffer

[Laverdaroo]

Sadly she’s dead, there’s no thread to get at to redress under closer inspection and the tap pretty much dropped straight down it. It’s got to be hellicoiled or more than likely an insert putting it in. Can’t try to drill and insert one at that depth, I couldn’t guarentee the results tbh………and it would be gash!

Needless to say that’s the summer over for the bikes, can’t afford any of that til later in the year which is a bit depressing. Hopefully I can retrieve my green flag stuff off this phone and try to get it dragged home. Mortally wounded, first time in 20 years………..gutted!


And 300 miles from home

That's a real bummer, Roo. I've never seen a plug as bad as that, I'm surprised it didn't blow out of the head. Not much holding it in. I hope the recovery goes well. 🤞

[Oddjob]

Try this kit Roo.

Cheap enough, has M10 x 1.00.

If you're not confident of doing the job find an engineer to do it for you. Maybe Matt could help. I'd be very careful using a drill on a plug thread, they have a tendency to suddenly grab and tilt sideways, I found a reamer worked much better. Not sure what size my reamer is as I can't find it ATM, suspect it's either 12 or 14 though. Maybe something like this, drill size is 10.3 for a M10 x 1.00 helicoil. https://www.ebay.co.uk/itm/234820266622?hash=item36ac60ea7e:g:xzcAAOSwgLJjme34&amdata=enc%3AAQAIAAAAwMwrFUBJstzNCqgqDrxI34hI8cQDCU5V72SxHFMIg8AS2K49Op%2FQH6X4JDzVDDcylNIio2RazWvEy4gfs8JFMeT96QKuqRmT%2BGNXyNRVxgo%2FVMIBSLdMni3P6l64229UxVT13L2BgtQyoACQpvJqZ9mktbXb5Xdom8I8FLNrWYgdybdnr8C3qDfia9sQ8GHeRy3VCbm8EvsSvmj6%2BpK2rS4RK%2BDHc9ndszPKamrBijtmtAd7BERtRuRD00t%2BKPEmVA%3D%3D%7Ctkp%3ABk9SR_ry1M-qYg

We used to do the cd175 with the drill clamed in molegrips and turning by hand, there is not much to come out

There must be a engineering shop in Leeds that can put a insert in for you 

[Matt_Harrington]

I suppose the issue is putting an insert in with the head off the bike which I'm sure you don't want to do miles from home! Moral support if you need it on your return!

[Laverdaroo]

Yeah the heads got to come off and not doing it here, it’ll be too much faff and too far from home for major surgery like that.

Rode it back to my digs on three pots and she  went surprising well apart from the Parp from the air popping out of the plug hole under the coil pack. Got a V3 600!

Does that qualify for Moto GP?

If the monsoons end I may lump it back early in the morning say 3am to reduce the grief but unsure if my mechanical sympathy will stretch that far…….

The LHG’s back from work and going to fetch my insurance details so I can bell recovery off that as I think it’s included on the policy. Due to a phone swap I don’t have copies on my phone like the prat I am

Bit cheesed off as it’s my bike but I’ll sort it by hook or by crook.

I would advise not to ride the bike as un burnt fuel will contaminate the oil, the oil will get very weak and damage the good parts of the engine   

[Matt_Harrington]

Roo, can you unplug the injector or does that screw up the ECU?

[sye]

Hire a van in Leeds from a national company and take it home, then drop the van off at a local depot. Seems the safest and most economical way of going about it?

[K2-K6]

You could try cleaning the hole with carb cleaner to de contaminate, the sticking a new plug in with Isopon, leave to cure properly and try it then.

It may hold, we used to use it to bond aluminium to base plate for milling on non uniform structures, holds really well but complete b'#stard to get it to release afterwards.

If successful, you can just wind the plug out when you need to repair with head off.

[McCabe-Thiele (Ted)]

If you did try & ride it back as it is the sump dilution by unburnt petrol might not be too bad as a hot engine would vent some out of the oil.

As Grahame said not advisable but it's not like you are using it except for a short period. When my 400 was on 2 cylinders for the first 80/100 miles the oil had no petrol smell though I have changed it to be safe.


Not sure how far you are from home but you could ride 100 miles at sensible engine revs then change the oil at every 100 miles.

Beware of fire risks !

[Laverdaroo]

Managed to blag a space on a low loader of a pal who’s running some stuff down south. The coffee is on me for the trip but I can raise to that. It’s howling down here in sunny Yarkshire so quite happy with that

Had various offers of support from members and even an offer of collection for fuel. That’s to all, fingers crossed, sorted but it is still daylight


What a fab forum, cheers all xx
