Thanks Ron - great info and very much appreciated. Ill take your advice and get the new cam chain and Ti retainers. I was trying to keep costs down with the retainers but your advice is sound. I have also heard MikeR mention these as well, and Nippon has them on his K1, among others.

many thanks
Andy

With head work, I would use the lowest rated cam, maybe even stock, to keep the revs down, if street reliability is the goal. You'll still get plenty of fun for sure.
I will be using a Web-Cam 41, which many engine builders poo poo. But most engine builders are looking for HP, not reliability. Ask your engine builder or cam shaft seller if they ever rode 6000 miles in 4 weeks with that cam and how many times did they get to use the power vs the steady drone of pushing big unused cam lobes against high pressure vavle springs.
Put the power peak where you live. You'll have to sacrifice the 8500+ rpm power. You'll not regret it.

Excellent advice!!! I've talked myself blue in the face about this subject on modern bikes.
One has to look at praticality/comfort and the entire power range, not just the last 2k till redline.

Let me say one more thing about springs, Some guys ran these bikes on fuel, some early forms of Pro Stock.. anyway there have been springs made for these that dont have a place in stock motors. Another thing, when you are setting up your springs its a good idea to check they are indtalled properly, spring height, not near coilbind, etc..

 Ti retainers, they are the price of a cam or a stud set, if you can only get one or the other, what would you choose.? If you got the bux to get both.. go for it.. can you live without them? We have 2 motors here that went a  combined 5  decades with stock retainers, no problems..

 An 836 without headwork, stock retainers, cam good pipe, will make  a dramatic difference..
