BBR120 kit + Web Cam and Valve Spring Inquiry

Recommended Posts

I am getting ready to install my BBR120 kit onto my XR100 motor. Along with the kit, a 68/69 Web Cam will be installed as well. I have two sets of valve springs, the BBR that came with the kit and a set of Kitaco valve springs.

Being newbie to 4 stroke motors, will it matter which springs I use with the Web Cam?

I Appreciate any feedback offered

Find a automotive machine shop that has a spring tester, use the spring with the higher pounds- resistance when compressed to the installed hieght.

I had the same springs... I used the Kitaco valve springs because they were a harder spring! It worked great for me Roadracing the bike!! With that cambo, and good exhaust... I got 10.3hp at the rear wheel on the dyno!

Thanks for affirming the spring choice, Brian =)
