Never mind all these motorbikes, where is my daily dose of internal cylinder photos :?:

It works a treat but its so over engineered it would, I tested it with the transit pickup so its strong enough for anything I'm going to throw at it but it is a 2 man lift :ill:

Guys, I've created a blog on my own site now. I figured it would be less controversial to post information about my shed adventures that way. I know that a lot of you really enjoy reading about my mad forays, but it would also appear that a minority of people simply cannot compute the kind of stuff I do, and it had the effect of infuriating them. I'm really really tired of having to explain my actions to people who frankly don't give a flying monkey. I don't know why I even bother caring, but I do. :roll:
I really appreciate the support I have been shown, so I'm not going to stop being a mad man. I'll just do it in a different corner of the Universe, where I won't be pissing people off. Life's too short to get into childish arguments about stuff that is completely inconsequential, so I think it's best if I post these thing in my own blog.

I will be updating the blog on a regular basis, so for those that were enjoying the information, feel free to head over to my site and check for updates. http://m-thomasius.com/blog/index.php

Ash, I thank you again for letting me get away with posting loads of pictures here. I understand now that it may have a been a little anti-social, so in respect to the site and the cost of running it, I will post all of this stuff off-site from now on.

Don't worry, I'm not going to bugger off completely. I'm just going to take my grinder elsewhere.... :hehe:

The 1125R is ticking all the boxes at the moment! Was over the Wicklow Gap road yesterday (Sunday). lOl
In the spare bedroom (not the garage) I am rebuilding a 1950's Douglas 350 flat twin engine!
Am going to reprofile the existing, or, get new camshafts made.
Before I get my geometry set out to draw the lift/degree profiles on graph paper, (for the guy with the CNC machine doing the grinding), does anybody know of any downloadable software that can help with the drawing/design part of this task?
Cheers J2T :)

I would be using something like Excel to understand follower acceleration with required valve open period, then look at trade offs with lift etc. you might also want to use Kastner type equations to estimate flow and see where your flow becomes limited by port dimensions rather than lift. With the right inputs you can get within a percent or so to flow bench measurements, based on my experience at a well known manufacturer of robust 1 litre per cylinder engines.
