I think that there they only see that it is safe, here is a manual for vehicle reforms that must be respected, you cannot install parts without a European approval password, the exhausts must be manufactured purely and exclusively for that motorcycle model, with a certification, it was not possible to carry a lateral registration, or cut the chassis, etc. and what may be regulated in said manual, you need a homologation project made by an engineer, with a favorable report, and a certificate from a workshop that It has made the changes, then it must go through the mot, where the changes in the circulation permit are inspected and noted, and if one day you want to go back you need to repeat the process

It's 38 pounds for the yoke, plus 13.99 for shipping plus 12.68 for import charges, the damage that #@%$ has done

the engine is already home, floor three please .... thank you

I have found the chain tensioner that has been threaded, surely it ever made a complete turn, it is already repaired and it works perfectly

then I have been watching some videos of how to close again to measure with plastigauge, and I have found an unpleasant surprise if they change the connecting rod bolts, 9 euros each bolt + 9 euros each nut !!!!! , I think they will remain untouched, is there another way to see how the bearings are without separating them?

You dont need to replace the big end bolts and nuts, they are not torque to yield type and can be re used

You may find that getting a socket onto the big end nuts proves a problem, I ended up around 40 years ago now grinding a socket down around the outside to allow it to fit. I still have that socket today and it's found a lot of use over the years.

Not sure if you can buy a socket to fit nowadays but that was my solution. It was also the only way to get the correct torque on after or I'd have used a spanner.

I recently had to do the same

I'll grind one, I don't think it will pose any problem, thank you, I'm more worried about having to change bearings but it is a risk that should be taken

3/8 drive six sided sockets are best to use

I have cleaned a little the cylinders and the number 1 piston, it seems that the chain has been very loose at times, the cylinders do not look bad but I cannot measure them without an alexometer, I do not have more rings, I suppose I will have to increase the measurement of the pistons, but until I measure the cylinders I don't know how much

Do not worry about gudgeon pin (wristpin) wear as they dont.
See what size feeler gauge you can get alongside piston skirt at 90deg to wristpin and what is the piston ring gap in the bore?
