ok, so heres a few things. im not 100 on kitting the ped just yet, so i was wanting to know a few things:

will the boysen reeds help and need a rejet

what will the high comp head from treats do (it said for 50cc kit, mines no kit) on the engine, again, rejetting?

my engine is stock, has biturbo and a filter from treats will be in the next order to get rid of the stock air box.

main things i wonder is what else ill have to do to the bike to make these work, what gains ill see (if any). mostly on the head, because i can hold off and just get the 70cc party pack.

Just do it and find out. your bike isn't going to explode.

Dont bother with the head if you're gonna kit soon. It's not that important. Especially for a cross country trip, long hours at WOT, It's not going to really help. It will give you a little gusto off the line. Yes, you'll probably need to go up a size too.

I think you're putting too much thought into these little things. You've got a good setup, just roll with it. Kit or get off the pot.

Wait... reeds? You have a stock (piston port) cylinder, so reeds are not what you should be concerned with.

Certain kits will give you reed options, others will not. Im not a tomos guy, but I think Alukit gives you reeds. While, say airsal does not. Most stock bikes have no reeds, you only need to worry about that if you get a kit with a reed intake.

Well, technically you CAN make a stock cylinder with a reed valve engine, but...

I'd also second the advice about not getting the 50cc high comp head if you're planning on kitting it. You'd do better to save that $30 and spend it on stuff for your kit (like extra jets or something).

some companies sell 50 cc cylinders and head. they are the stock displacement, but have a more radical port design
