By the way. Its a 1995 Heritage Softail Classic.

Hi guys. I just spend 10,000 pounds for a Harley Davidson. Its a second hand one and there are a lot of goodies. Its a beaty with all the meaning of the word. And its parked right next to my Z. What a feeling when you ride the Eagle. You feel that you own the world. What a beatiful couple. So whats next. :) :) I will take some pics and post them.

So one option is to remove them completely. Another one is to block the vacuum feed of the stock rec.valves? Is that the small metal pipe of the stock rec.valves that the vacuum goes in? Which HKS you have? The Super Sequential or the Sequential ones?

Whats the maximum boost HKS sequential valves (not Super Sequential) can handle? Mechanic told me that they cannot handle more boost? What the hell.....Only 9PSI of boost?

I have put the vacuum from my first attempt back to its place. So there is no leak from that.

I bought (second hand) a set of Sequential HKS BOV with hard pipes for 90 quid. Thats the older version of HKS not the Super Sequential. Anyway...I spend few hours installing them and now my boost doesnt go over 8.5 to 9 PSI. What happen is this. 1st attempt: Install HKS BOV without removing stock recurculation valves. So now I have 4 BOV. Boost goes fine as much as I want. Problem: BOV does not sound good because of the stock recurculation valves. 2nd attempt I remove the vacuum from rec.valves and i used it for HKS ones. This means that I have cancelled the stock ones...Right? Problem: Boost does not go over 8.5-9 PSI. Why is this....? Do i have to remove the stock ones completely? Or am i doing something wrong?
