Ive seen numerous discussions around this topic. I'd like to hear from guys who've made the swap directly from bpipe to PFP with exactly the same setup. I want seat of pants impressions: bottom end hit, how quickly it runs out, jetting changes, set up troubles, any maintenance ... Cost is a major letdown, but outside of that I've yet to hear a negative word about the PFP. My bpipe has worked flawlessly for 4 years so I'm not looking to dump it but am getting more interested in other possibilities. Ive never used a mod chamber yet either, so I'm thinking about that too.

which engine do you have???
SS Dasa 850. I' think its the edge of whether it's a large enough displacement to benefit from a PFP. The PFP flows better for sure...don't know how that can be deleterious though. I'm not dying to have a new pipe but am def interested.

Im in the same school of thought with my Gomez ada 951. I'm dancing with the one what brung me for now ,but I'm interested in the PFP. Let me know if you want to use my Mod chamber ,Got one sitting. I'll be down next week .

You can ride my XFR with the Dasa 900... It's a ss cylinder like you have 89mm bore with a little lower end help to make it 896 and not 846...., but it will be power factor, msd TL, 144 mag...
No down fall to power factor pipes now there's a waterbox ... But it's a different riding style for sure

The difference between a mod and a limited chamber on a b pipe is negligible. The only difference I notice is my mod chamber is way easier to install and the limited blows.
As for the power factor pipe I can't comment. I won't run a pipe that doesn't allow me a full size gas tank and have never tried it.

chucky told me 850cc+ for PFP
I am curious about this Josh. Can you describe exactly what's different in the riding style between your standard B-Pipe setup and a PFP setup? Does it take a while to get used to? Does it change the way you do tricks?

This is what me and other power factor pipe owns always talk about... Let a guy that's use to a b pipe ride your power factor ski, he comes back and always says that's crazy, but if you watch them ride there not even close to the power band...
You will see with the PFP we run a little higher idle, we always brap, brap, brap around to keep the pipe cleaned out. Not that it loads up , but it's something you get use to.
B pipes have a great bottom snap and then it's over.. Some guys say my b pipe pulls like crazy, all over the power band... Wrong!
Power factor will really start pulling in the mid, higher it revs the hard it pulls... Like on my Dasa 1100 the hit was unreal, go for the first back flip was simple , but keep the revs up say in the mid and go for the second flip the ski would pull even harder to the point it's hard to stay connected with the bars.
You will ride a little faster with the power factor, not at first but once you get use to the power and how the ski comes alive.
You can't compare a b pipe to PFP on big motors... I know rode my xs1000 for 8 months on a b pipe, then went to power factor with water box... It's was like adding 200cc
Other notes,
you can see and touch the starter with pipe in place... Opens up a lot of room around the motor.. Other say I can't run a big tank, you can't ride these big power skis for long rides... Plus a 4 gal jazz tank will clear the power factor pipe in most a/m skis.. Brian at Thrust has these tanks in stock...
Look how many guys are riding these dry pipes now, even surf skis.... There's a reason !
Also look at cost... New b pipe $785.... New A/M water box $250 plus shipping etc ... So in the end the b pipe is $300 cheaper, and makes half the power..

hey Josh at your opinion, do you think PFP is better with power valve engine or it can be good too in non power valve engine ??? do you ever test it in a non PV engine ???

IMO I think PV's really help with the PFP. Talking with Chucky yrs ago about running a PFP on my 6 mil ADA motor, he said stick with a B pipe I would losse to much off the bottom with that motor (Non PV)...
XS has setup a few SS865 motors (There PRO package) with TL & Power factor and had great results... No reason not to try a PFP on the Dasa 850

exactly what Art told me about my 5mil ADA top end.
Josh, I'm finding out what u guys had already said...the Dasa engines like to rev and my PV's really don't pop till the revs are up. I guess that's a causality of having the bore and stroke out of square. It's a def change when the pv's pop, but u gotta get it spooled up. I was thinking the PFP would allow the SS engine to get up there quicker and thus hit sooner. Brian has suggested using a soft wedge (hydro turf) to keep the PV's open off the bottom. He also said he's working on softer springs for the pv's since theyre the limiting factor in getting those guillotines to slide up. I was thinking about clipping the springs shorter to decrease the tension, but Brian said he's already gone that route with limited success.

I'll let ya know how mine works, I'm running your same top end... Just custom bottom end with custom domes...
But I would try cutting the spring a bit, worse case you buy new springs

KTM offers different PV springs....might be worth a look
or clip off just a TINY bit...wont take much to reduce tension......and this opens up a whole new can of worms thats never really been much discussed...

the pfp will make a huge difference on anymotor. roo on here was talking about how great his 701 runs with one... i've preached about dry pipes since i started riding skis 2 years ago.
