Hi Anne, nice progress, in the pic below you can see the Devimead solution for lubrication of the Timing side bearing, the original pressure feed is blanked and a small cavity is created on the top side of the bearing boss allowing oil to drip into the bearing.

hi Gavin, that is indeed a clever solution, being a needle roller the dripfeed is more than enough. As you can see in my earlier posts I used a scrub srew with a 1mm orifice. Same setup as with the old engine which lasted some 32 years/ 12000 miles. Regards A

see post 500026 and just follow the links

been a while but this christmass the new engine is work in progress.
solved the axiaal end float voodoo, made a new bearing out of some phosphor bronze.
in the end it is just a 5,25 mm thick slab of bronze, milled to the correct dimensions. end float is now 0,04 mm





next jobs on the list are:
1. camshaft
2. the SRM-Oilpump
3. gearbox, pity the five-speed from Scotland isn't available yet so have to resort to the four-speed.

regards A

Hi Anne

Nice to see your moving forward again. With regards to the 5 speed clusters, I've been surprised by the lack of interest, other than myself the other two which I know are in use, Mark Parker and Gavin Eisler are happy with the performance, of the 11 sets sold others don't really give you much feed back.

Hopefully your post can generate a little more interest, at the moment there are your self and four other who have shown an interest. I need to order a batch of ten, so if anyone is interested PM here or get in touch.

regards

John

well the five-speeder can be exchanged with the engine in the frame, so there's no real hurry yet
still..... I want to shift one more time when they don't expect it.

the bike used to be run two-up and then the four-speed hasn't the best spaced ratio's.
future use is again two-up
regards A

progress with the new engine is slow, very slow. with the upcoming winter season the objective is to have all components ready.

and now the camshaft. I purchased a 90-drg camshaft a couple of years ago. and it is not straight. although new the complaining period is long past and I'm having a new one made at the local camshaft-shop

http://www.hurricaneracing.nl/

question now is:

are the profiles for inlet- and exhaust-cam identical?.

regards Anne

I think this also alters depending on if its an original cam (to which I think your referring) or a remanufactured item, which I have seen lift heights and duration different to that of the factory item (and different to other makers versions of the same cam)

The SRM race cam as far as 360 degree motors are concerned is a good cam.

I do think so but where can I find the profiles for the inlet- and exhaustcam.
I do not think they are the same.

It seems I can no longer view the images on the forum threads unless I fork over money to photobucket to upgrade my account. Or am I doing something wrong?

No, Dave you have to pay money to upload your own photos from photobucket, you still won't be able to see others photos unless the poster of those photos pays the ransom too


When given the choice between two evils I picked the one I haven't tried before

Go to BritBike FAQ.

Look at the photobucket ransom post by Andy Higham.

If you use Chrome as your browser you can install the app mentioned that shoves it right up Photo*uckits backside and allows you to view the images.

It works!!
