Hey guys, newbie here trying to help my computer illiterate buddy get some top end. He has an 06' er with a 13:1 Wiseco piston, +3 Hotrods crank, Jansen racing mx ported head, stock valves, Dasa 98 db exhaust, and a Hotcams stage 2 cam. He loves the way it pulls on the bottom and mid but wants more topend power. Gearing is 13/37 and the head has stock valve springs, but the machine work has been done on it for a bigger cam and springs. Is a stage3 Hotcam enough to help him out or should he go with something else? He probably weighs in at around 220 also. What about adjustable cam gears? What would be a good setting if this is the way to go? Thanks in advance for the help guys.

I forgot to add we ride from 5000-8500 feet elevation, lots of sand duning, circle track racing, and dirt track riding. Looking for as much top end as possible without losing too much low to mid.

That's what I was telling him, I just switched from a stage2 to a stage3, but for these things it seems like your choices are endless. What is the biggest cam you can do on stock springs?

you can use the stage 3 with stock springs , I did for a little while, some people seen issues with them valve float,other people have ran them for hors and no issues, I just would recommend them specially if he's gunna run at high rpms a lot, or ur stock springs are real old

i really like running stock gearing (14/38) on my bike. It pulls hard on the bottom and still has a lot of top end and with the stage three the mid range is golden.
