Thanks for the heads up on the bits Jeremy.

Have heard the 3rd gear fix hasn't panned out on the new ones, hope it works out for you.

Benny,

Looked into it, can get a 108mm piston and max reliable stroke of 80mm, so 733cc. Would be awesome but can get a solid 300 smoker and register it for a few years for the costs involved. If I toast a cylinder or crank then yes I will upgrade, but when both are still servicable I just cant justify it.

Will be basic build with higher comp lightweight piston and stock parts, going to try and do a wide ratio tranny too. Think I may have nutted out my problem with the engine having a big flatspot around 4k rpm and am expecting better performance with valves that seal so that will have to do me.

So I got the camera working, but unfortunately it seems I really cant take photos of engine parts.

A pressure test confirmed the cracked head, and inspection of valves showed they were all leaking and the inlets are toast.

Also found this while I was going through.

(Yes I said I cant take pictures of small stuff)

Its part of the sprague clutch which came adrift and got ground up.

from there it found its way to the top oil pump which scavenges oil from the crankcase.

Image

which then feeds oil onto 4th and 5th gears

Image

So pretty lucky I was in here too find all this early enough. Along with the output shaft I already knew about its time to try and find a good second hand transmission before costs get out of hand, with a new set of bearings and no more metal going through it I dont see why it wont go till 100k without an issue.

Maybe use that for really close up stuff [lighting will be important as well in macro].


Yep, got it on macro.

Presume you are right with lighting, and probably background colour, lack of tripod, plus camera settings which I havent the first clue about. To be honest, am happier working on it than learning how to photograph it so will go that way instead.

Picked up this 'superlight' 'superstrong' stand a while ago, am going to give it a go in an effort to loose some more weight off the bike.

Image

Will have to make a mount for it but cant figure out what it uses for a bearing/bushing on the pivot. Its meant to fit a 01-07 RFS, anyone got a photo of the OEM mount or one I can have a look at/measure?
