BLOWN HEAD GASKET CAUSE ON SUZUKI K10P, THREAD INSERT REPAIR

[@colinwellman9480]

It's to be hoped you're keeping those 'Gentleman's magazines' under lock and key and away from Jenkin's eyes. Where would we be without thread repair inserts. They provide a simple solution to stripped threads especially in alluminium. Small Honda from the 80's? Oil Leaks and Honda's don't seem to go together. Thanks for the video.

[@TweedsGarage]

That's what i thought Colin, but it is an issue on this particular model because its an over complicated oil seal which can only be changed by splitting the engine, so they didn't get changed ( unless you were a courier rider trying to making a living so you'd rip out the old one, bash in a new one with copious amounts of silicon sealer and call it done! )

[@nickcarter9538]

I loved my K10, never had plug problems but was forever cleaning the exhaust port.

[@TweedsGarage]

Suzuki were quite generous with the oiling 😁

[@asciimation]

Next day delivery. Sheer luxury. I am lucky if things arrive next week! I never knew you could stack the inserts. Makes sense as you say.

[@TweedsGarage]

And i found out from Dean that the collars on the insert tool can be adjusted to a set depth ( i wondered why they had grub screws in them ) ...every day's a school day Simon 🙂

[@GordonjSmith1]

I learn something every time I watch, and love the cheery banter.

[@TweedsGarage]

Glad to hear it Gordon 👍

[@thebracketfactory]

Nice work Mr Tweed ... she lives to race again!

[@TweedsGarage]

The Stan Stephens tuning stickers add at least 3 hp

[@thebracketfactory]

@ when you had the barrel off, did you see any signs of port based fettling?!

[@TweedsGarage]

@@thebracketfactory nothing to fear, its a sheep in wolf's clothing😁

[@steveturner8840]

That’s one heli of a job Mr Tweed 😂sorry but I couldn’t stop me self

[@TweedsGarage]

Boom boom.....here all week and matinees on Sunday 😁

[@leondown6869]

Reverse intro amused me. Many years ago my Bultaco was reluctant to start. When it did fire up it was running a bit rough. Girls watching. Gave it a handful of throttle dropped the clutch ...dumped me backwards into hedge. How they laughed. V simple 2 stroke engine...would run backwards almost as well as forward. Heady days.

[@TweedsGarage]

Apparently this is something i need to watch out for with the Bantam 😁

[@razor1uk610]

​@@TweedsGarage..A Bantam 173 3 gears was my 1st bike in 1996 fully road legally yet semi-illegal grey area on capacity, but with only roughly 3.5 hp and a max speed of under 53mph on the clock, it was lesser than most fifties, except it had stonking torque compared to them. Anyhow I was warned never to somehow push/bump start it backwards as it would run backwards with it's dynamo ignition.

[@iancharlesworth3654]

We've got to see it back up and running Mr Tweed. 🤞🤞🤞

[@TweedsGarage]

I'll keep plugging away at it ..

[@retromechanicalengineer]

Super dooper. You can also set the little collar on the insert tool to the depth you wish to wind in to, it will magically stop when you get there. Wonderful stuff. Best wishes, Dean.

[@TweedsGarage]

Thanks Deano, I wondered why the little collars had grub screws on :-) !!!!!! ( every day's a school day )

[@petermckee1061]

Nice repair Allan. And looking forward to seeing the Honda. Cheers, Peter.

[@TweedsGarage]

Its on the list Peter👍

Memories memories my first bike was a maroon Susuki K10 which my late uncle bought as a basket case, after rebuilding it he used it to get to work for a few months and when he brought my aunt over to visit my mother and Grandmother i was nagging my parents about getting a motorbike he had a quiet chiinwag with dad and said to me how much money have you saved towards a bike i told him i had £25 ( I'd been saving for ages!) he said I'll see what i can do leave it with me then the weekend before my 16th birthday he came over again ( my older cousin rode the bike over!) and said how much do you reckon i said £15 ?? That's a coincidence thats exactly what i was thinking, he made sure i got insurance and my license and the deal was done , I was mobile (1971!!)😅

[@TweedsGarage]

Sounds like a great 16th Birthday Bill and at a time when life was more carefree than today 🙂

[@chrissills962]

You meet the nicest people on Honda, very informative Mr Tweed.

[@TweedsGarage]

Thanks Mr Sills

[@leslieaustin151]

Yeh, c’mon, let’s see the rest of the work on the Suzuki before we see the oil-leak cure on the Honda!! Really enjoying the bike repair work, thank you. I’m off to the shed by the tracks now. Cheeribye! Les

[@TweedsGarage]

I shall fire up the camera for reassembly Leslie.

[@shedbythetracks]

Thanks Mr. Tweed, You're a heck of a guy! I used heli-coils on the handlebar mounts of my Yamaha... but if I told you how I drilled the holes out it would probably send you to the hospital. All the best to you and yours

[@TweedsGarage]

I did see that episode and I am still having counselling!!!!

[@MichaelBooth-wt1zy]

Better still use Timesets or a stepped stud. 😁

[@TweedsGarage]

all good options Michael

[@cainbeeping8480]

Good job brother

[@TweedsGarage]

Thanks

[@martinwade9421]

Nice job! For a horrid second, I thought that you were going to drive the tap in with the milling machine. I should have known better.

[@TweedsGarage]

oh ye of little faith Martin ;-)

[@howardosborne8647]

A man down the pub said this is the very Suzuki that Barry Steen won his first race on.....I think he's exaggerating🤣

[@TweedsGarage]

Must have had the wind behind him...

[@nickaxe771]

Very interesting Mr Tweed....is there no req to thread lock the insert in....or is that not req?

[@TweedsGarage]

Not normally Nick, they keep themselves in place ( they are compressed and slightly bigger than the threaded hole so are in tension against the thread they sit in when wound in )

[@nickaxe771]

@@TweedsGarage I see....that make sense now you explain it.

[@chrisbrewer4711]

Did you heat treat the copper Gasket on re assembly?

[@TweedsGarage]

The NOS copper/asbestos sandwich gaskets won't require heat treatment but if I was using copper sheet gasket then I would heat treat it.

[@StuartsShed]

The joys of buying a motorcycle from Gary Gorilla and encountering his dubious maintenance malpractices………..

[@TweedsGarage]

Unfortunately he owned a lot of cars and motorcycles in his lifetime......

[@StuartsShed]

And machine tools, it turns out.

[@TweedsGarage]

@StuartsShed indeed, i think the son of Thor was the previous machinist on my lathe as the jaws of the chuck were worn in every direction ( hence the reason to buy a new one, it was beyond a light jaw regrind )

[@razor1uk610]

Please don't reuse the old insert as it looks very short, much too short to contain the forces upon it, hence why it failed again pulling out even more of the barrel's remaining threads from the previous repair. You might need a bokt with a longer threaded depth to properly engage the helicoil perhaps ?

[@TweedsGarage]

that was the remains of the original aluminium thread coming out with stud.

[@TomWaites-gi7le]

Really good video, always like to see you work you explain things in uncomplicated way, definitely like to see reassemble of the suzuki 😊

[@TweedsGarage]

I shall hit the record button then Tom.
