What Pipe for a lamey 771 freestyle engine

[custom rider]

I have a stock stroke lamey pv 771 engine in my freestyle ski. I ride with a factory b pipe but I have a blue factory dry pipe but I havent try it yet. What pipe is best??

My setup:
Atp total loss
Atp dual 48 carbs
V/force
ADA head 24cc 220 psi
Lamey pv 771 stock stroke

Thanks

Dunno much about Lameys, but, Try the blue pipe, if it works better leave it on, if it sucks take it off.
Thats what I would do.:biggrin:

From what I have heard, if you are going to do the dry pipe use water injection and that will wake up the low while keeping the great mid and hight that the B doesnt have. You may find the B pipe has better low end though.

I had that same motor set up (stock stroke x 85mm bore = 772cc) and I loved my 'b' mod.
Granted, I ran it fairly wet, on a separate cooling circuit, in 40º-70º F water.
You can do a ton of different things on a 'b' pipe - there's a reason pretty much everyone runs a 'b'.

keep with the B, or....get rid of the blue for a speedwerx freestyle pipe....


but you cant go wrong with the Bpipe...

In Denmark we have winter now so it is not possible for me to test the pipes and my next problem is that I am starting to build an new xft 26kg. backflip hull so the old ski is a part now.
I have msd water injection for the dry pipe but I dont know how well the Lamey power valve cylinder and a dry pipe work together?

Bo- I would use the "B". You are going to do some grinding to get the headpipe to fit over the PV's. I'm not sure about the Factory Dry working with the PV's.

Also, there are spacer plates that you can use to clear the PVs so you dont gotta grind the pipe out

I have used the B pipe for a year now and know how well it is runing.
My interest about the dry pipe is only because I have one in spare.
Thanks, Bo
