So, fitted my oem yamaha raptor 660 petcock with a 90 degree outlet. Drilled and threaded and locktite. Hopefully Its sealed tight and works for years to Come.

Also ordered a xs clutch Kit, after advice on this forum, Hopefully it works as attended :)

Tomorrow i Will ask the machine shop thats gonna bore and hone my cylinders, if They Are able to mill out the Reed area, so my v force Will fit.
Fingers crossed They can do it All in house.


Stay tuned folks

So, my uncle helped me out again, and Got the cylinders prepped to fit the yz85 vforce reeds.

Next i Will be delivering the cylinders to be bored and honed asap.

So, finally some progress

After receiving the cylinders from bore and hone, i dremeled out the 'bridge' in the in the cylinder ( Reed goes in), cleaned it good, oiled up and Got the top end together. Sprayed it with heat resistent clear coat afterwards to protect the bare alu.

As It sits now

Next i Will try to make a seat pan( No expetience what so ever) in some 1,2mm sheet metal. Hopefully i can make it work

Sorry for the lack of updates, but life gets in the way.

But, I have stainless news for you, allthough i havent fit Them on the bike yet,
A set of laser Cut and welded, glas bead chain tensioners.

I think They turned out pretty, now They need to fit and Its perfect

So just a small update, letting the internet know that the build is very much alive

Cut the brackets this weekend under the frame, so the pipes cleared the frame.
Got the hvc cycle sidestand extender on, but Must admit i Hoped and thought it would be a plug and play, it definately not is.
If Iam Lucky i can find some sort of rubber to go on the spring so it wont hit the pipes (as hard) or i Will have to take drastic measures.

Also Got my one off stainless steel chain tensioners on, They turned out good :)



And oh.. Allthough i Cant afford it, (the restoring and custom work etc) i had to buy a New project for the future.
It was a frame with papers, a somewhat complete engine and some other bits and pieces. ( Its not a rebuild, making my own take on it)

Suzuki gt750, ska the kettle aka the water buffalo 😅👌
I just had to do it.

Stay tuned

Those chain tensioners look good
I will look forward to your GT750 rebuild thread in the near future

Weekend update

1 issue solved, i took the clucht out and the kickstart mechanism, Saw the First shim that goes on the shaft was to big ( having issues with it not popping back up when i kick it)
I found the correct shim, put it All together and it works as intended.

Another one that had been irretating me, was the fact that my clip ons hit the gas tank on Both sides when turned, but i Drilled a 4mm hole in each steering stop on the lower tree, put a 4mm bolt in with a narrow head? And it works perfect, without destroying the tuning radius. Looks fine to me.


Next i Will properly address the tdc
Any tips/ etc on how to do this would be appreciated. I do have a measuring clock? That goes in spark plug hole
Plus i am Also using Electronic ignition, but having never done Any of this before, Please do Come with advice

Good to see more progress

What electronic ignition are you using?

If it is Newtronics, there is a lot of previous posts regarding setting it up

If it is a different manufacturer, you might want to raise any queries in the 250 and above Tech Help Section

Edit
Sorry my reply made less sense than usual as I replied to the wrong thread

However it's good to see progress, however small, to your rebuild
