Jeffro,
It is one carbie with a primary side and a secondary side. You can see from the cylinder head photos that the primary side is quite small for low down response and air speed where as the secondary side is alot larger to produce power and consume more air.
When I take it back off I will get a photo.

Cheers,

Well I have tested the seat on a 180km loop about 2weeks ago and I must give it a big two thumbs up. The seat was very comfortable and soft in the right places and also wide enough in the right area. so you don’t feel as though you are sitting in an Austrian Railway sleeper. :pinch:

Here is the link to ACM if anyone is interested.

Great Job ACM!

I have finally got all the parts back and have re-assembled the big Ten.

I installed a 101mm Forged Wossner Piston, which is stronger and lighter than the std cast unit.
This now brings the capacity up to 673cc

509gms V’s 535gms (Improves response)

Piston Installed in the barrell bored and honed to specs

Cylinder Head serviced, machined and welded

Ready for another Adventure

I rode the big Ten today for the first time and put around 30km on her, then got back to the workshop for a check-over. I am really happy with the end result as she has plenty of torque as well as power when you start to open her up. I only just touched 5000rpm and it feels great. The only thing now is that it needs a carburetor service which, if I have time I will do this tomorrow.

More Later!
Cheers, Lefty

I bought a pair of Photochromic Ugly Fish sunnies from Chris at the B-Day Ride that was cancelled. They are without doubt the best value for money sunnies that I have ever bought. I actually did a 180km Adv ride last Sunday and wore them inside my new Zeus Adv helmet and I didn’t even knoe they were there, even when it was getting dark at around 5pm.
I also wear them every day.

You won’t be disappointed if you buy a set. But I reckon you had better hurry.

Cheers,
Lefty

Hey Fish,
I hope that you had a great day champ!

Happy Birthday!

Sorry Chris, I won’t be able to make this ride. It looks like it will be a top day. Have fun fellas and ride safe.

Dude, that is a good question that you ask.
I have struck a few issues along the way with the BIG TEN. Firstly the oil leak from the cylinder head which was then found out to be a huge crack in the cylinder head rocker cover from a previous “Bone Head” who had tried to remove the rocker cover with a tyre lever and broke it :angry: and now it requires welding and machining.
Then there is the flywheel; I actually broke 2 pullers trying to remove it. I then took the complete engine down to a Yamaha dealer and asked him to remove the flywheel which he could not remove it without firstly risking damaging the flywheel and a high probability of damaging the crankshaft. :ohmy: Which took me a complete day.
It was after these issues that I decided to leave the bottom end as it is. It measures up well within Yamaha’s Specs as far as I can measure, and unless Jeffro has an unlimited budget I am not prepared to risk a possible crankshaft and flywheel as well as the additional labour costs.
As for the bottom end the way that I look at it. The bike is a low revving low comp engine designed to do big kms. And yes while the bottom end looks and feels fine there is no doubt it could fail; however it looks like it has been well looked after and on completion of the rebuild I would not hesitate riding the bike to Perth and back.
Yes sure the clutch an gear box has also done many km’s, but where do you stop? Short of getting a complete new engine and drive-line assembly. :huh:
After the completion of the rebuild I will do between 300 to 500km to run the new engine in, replace the engine oil and filter and then Jeffro will receive the BIG TEN back ready for any Adventure. :woohoo: :woohoo:

Thanks for asking.

Cheers,
Lefty

Just an update on the TENERE..

Waiting on a Piston Kit from the US, then it can be bored and honed. Will check on the head service and welding tomorrow.

Cheers,
Lefty

Bugger! As you said, at least you found it when you did and not midway across the Simpson or somewhere similar. I have an older (95) model but will check it anyway.

I pulled yours apart, cleaned and regreased it yesterday Jeffro. It is a totally different link and it is steel not aluminium. The pins and sleeves are a little worn but all clean and re-greased.
