Do i need to renew the engine and head bolts when i replace my cylinder and head? Or can i just use the old ones?

You could get away with the old ones, but they will have stretched a little and lost some of their tensile strength. It is much easier to accurately set the torque on new bolts (particularly the head) rather than used ones.

Hmmm oke oke thanks
Not really convinced to get new ones because they are 120 euro total.

Kev do you renewed them? or do you know other big bores projects who did?

I used mine a few times & never had any problems they are not stretch bolts so you will be OK.

Okay thanks!
did you use locktide?


Also busy with a temperature meter for my oil and coolant :)
Pic's will follow.

Not on the head bolts.

Okay thanks!

Cylinder is now in america to, for big bore and powder coating.

And good news from the company that's working on my cylinder and head. The head is already done and they only need to finish the hone and plate work of the cylinder.

And also there is comming a skid plate for my xt660 from germany :woo:

Looks like all the mods are coming together.

So i had a good deal with some akrapovic cans :077:
