Hi, ive had the opertunity to buy a factory compression head for my 06 beta for not a lot. The friend im getting it from said he was told that with this head and boysen reeds it would smooth the bike out at the bottom end. He had an 07 beta. He fitted the reeds and felt it was smooth enough so never fitted the head. I dont know how much difference itll make to my bike but just got a few questions:

1. What size gasket will I be best getting for the new head as i know you can get different thicknesses.

2. what difference is there between boyesen and v-force reeds?

I might do what he did and just fit reeds to start with and then mess around with the head afterwards. Has anyone else used one of these heads and what difference did it make?

Cheers for your help.

Always best to do one thing at a time.

Difference between V force reeds and Boyesens is about 100 quid, I used Boyesens on my Rev3 and the improvement of low end power is really noticable. The bike seems never to stall, runs better low down and picks up strong but not sharp. Try the reeds first I doubt you'll need the head after. Make sure you loctite the small screws holding the reeds on to the block and spend abit of time making sure you get a really good fitting screwdriver to take the screws out as they're easy to round.

You dont need the rev plates with the Boyesens and I always removed the spacer between the reed block and carb which gave better response to the motor along with making putting the carb back in easy. Motomerlin sell Boyesens if you dont know where to get them from.

V Force reeds can be a ******* to set up but you shouldnt need to rejet the carb with Boyesens, I always used a 27.5 pilot jet in mine which worked really well
