Cool, danke Greg, Sepp und Ali.

Hab grad mal mehr und bessere Fotos gemacht kann die aber nicht gross genug hier raufladen daß man sich die Sache da gutt genug ansehen kann.

Hier ist ein Link zu einem Flickr album, die Sache ist privat ausser du benutzt diesen Link: https://www.flickr.com/gp/acciarini/0D7A5Q

Hier findest du Fotos in größerer Auflösung.

Cheers,

Thanks Greg.

I did turn the crank and everything seems quite solid, no play as such and no heat discoloration around the bearing race or case aluminium, I wiped the oil residue out of the bottom of the case halves and nothing gritty in there.

The guy I bought it from was the brother of the guy who bought it from the guy who had supposedly drag raced it at the Brighton Speed trials, looking at the archive info on the entrants there seems to only ever have been 1 TR1 raced there and only once.. my guess is the buy built it, raced it and lost then got himself a different machine for the following year.. the engine does not seem to have suffered from catastrophic failure and the brother said it was running before it was taken apart to be fitted with bigger pistons.. possibly the 1100 conversion..

As for my 'knackered pistons' (and here my lack of experience with mechanics will show) could the broken bits of skirt not simply be turned down? A lot of pistons seem to be of shorter overall height as far as I can make out..?

Then back to the many trodden path of 'are there no other pistons that can be used? What is the specs of them, diameter and gudgeon pin dia and height? I really don't have a spare £300 or so at the moment to buy a set from halfway across the World and then pay another 25% vat and import handling on top.

I will find out if Sepp has any and at what price but I already know the project is going to take quite a while so no harm exploring all possible avenues.

Looking closely at the break area makes me think the skirts got knocked when the boxes of parts were moved around as they were just lying loosely in one of the boxes. I can chuck them on the lathe at work and check them, if the skirts play no essential roles in the running of the whole then I have nothing to loose by turning these down..?

That would be very cool, otherwise I'll have to look at going the stroker way. Correct me if I am wrong but longer stroke usually means more torque whereas a shorter stroke means the engine revs up easier..?

I habe heute die Kurbelwelle mal gegen die von einer XVS1100 ausgetauscht. Der Stahlring vom linken Gehäuse sieht für mich noch ok aus aber Spezialist bin ich ja nicht, wie sieht dan so einer aus wenn er futsch ist?

Servus,

Rant.
