[QUOTE="timetraveller, post: 99304, member: 456"] I think that you might find it harder than you think Vic. I made five plastic or wooden prototypes before I got it as I wanted it and I had the advantage of having a UFM off the bike and on a work stand so that I could play with the parts and have a good view of what was going to hit what. I still got it wrong because as soon as I mounted the UFM plus damper on to an engine I found that the long ally arm was hitting the front exhaust valve spring cap. Fortunately only by about one millimetre so that I could relieve the ally arm by that amount. The next batch of arms, which will be milled out rather than laser cut out, will have that mod incorporated. If you can produce a better design then you would be doing us all a favour. If you want to use the same damper then you are limited to that 75 mm total travel and in reality one cannot use all of that. I settled for about 65 mm and Vincent for about 70 mm. I know that a longer lever arm would produce more movement but both Vincent and I are using most of what is possible with these damper. I look forwards to seeing if you can produce a better design.
