Super Jet Pipes, pipes and more pipes...

I know they have, I'm just saying if rarity and low production really meant value then they should be worth double that. That's not the point of this thread though. Moving on, I have found only one issue with my currently setup Sizzler, a gear clamp broke at the mid-band portion at the waterbox...while riding. Yesterday I had some decently big air for what I'm used to and the pipe held up to it all perfectly.
 
I think the $900 'B' Pipe you referred to was an FX-1 version. These are very rare and attract a premium. I don't know if I'd pay $900 for one but I guess the seller is free to ask whatever they like for an out of production item. In the end the buyer sets the market value by either buying or not buying at that price.

Do agree it seems ridiculous that people pay almost full retail for used 'B' Pipes. From memory Factory Pipe does their 'B' Pipe run about this time of the year. I suggest people make their purchase in the near future whilst stock is (relatively) plentiful. Wait 6 months and used pipes seem to be the only optiono_O
 
So, I am going to say the verdict is no on the SX-R 800 chamber fitting in the SuperJet hull. The head pipe might work with the Coffman manifold but I think the manifold would need some clearance modification. As of right now, it doesn't want to work out in a friendly manner. Back to the beast and so far best performer I have...Speedwerx! :D

I have never had a chance to run a b pipe on my ski due to the unusually high price for used pipes. But compared to other skis I have been on with them, my experience tells me the Speedwerx was by far a more potent pipe. The only issue I am having right now is keeping couplers on it. It's not a freestyle/freeride pipe and the added weight of the water jacket is too much for the hard landings in my opinion. My manifold spigot on the pipe is spider cracking from being thrashed around off of the hard landings. I think if it were more solid to the engine it would eliminate a lot of the little issues. But nonetheless, best performing pipe I've experienced yet.

I'm running about 6850rpm with a mod chamber bpipe ported 727 high compression big carbs etc. Somewhere in between the Coffman and the speed werx in performance I'd say. I might pick up a speed werx to experiment with, still a few out there to be had.
 
John at Speedwerx told me to run 37cc domes and stay close to stock compression if I intended any wide open throttle runs for more than 5 seconds...which I rarely do but still do them. I'm wondering if anyone has run 35cc domes and had no issues with full open long runs. I may change up to more compression if it works out well. Otherwise, I don't really feel like I need to. I can pop the ski out of the water easily as it is now. BK, what compression were you running?
 
Update time!

So I have decided to slowly build a B pipe over the off season. My favorite pipe has temporarily taken a self destruct leave of absence lol. As noted in earlier posts I have been fighting with coupler issues this year with my Speedwerx pipe. Well, about a month ago the gremlin finally surfaced. First I must say I am quite happy to have bought my Coffman Sizzler as a backup. It held me over up to now. But it's time to move onto B pipe territory :D

Getting back on track with my beloved dry pipe though, I spent a few good hours really thoroughly examining it and have found that the needed modification work done to it was not quite enough. I still do not understand why it took about 2 years for the pipe to suddenly start blowing couplers, but now I can correct the rest of the issues. So as mentioned, the pope was slotted at the Lord mount locations and I figured that all the needed work was already done. I have never had any issues with getting it set up before. In fact it always went in quite well. This past Sunday though I decided to devote a good part of the day into figuring out what was the issue. It appears that the angle of the stinger outlet is up a few degrees too many. I have read about this in the past but was not sure what exactly they were referring to and given the slotted mounting locations, I assumed this was nothing to be concerned about or it would have been corrected.

When setting the pipe up without the coupler installed I was able to see now why the couplers were blowing up. The outlet had enough force from the hose against it pushing t down that it was pulling the pipe away from the manifold opening an excessive air space inside always blowing out the coupler on the bottom. The force against the spigot going into the manifold was actually severe enough that it destroyed the spigot, tore it half off. See the photos? Yup, so that just happened on my last ride with it.

After going through a long period of shock and depression over this lol...I decided to finally do something about it. My first thought was to break off the damaged portion and file down a clean edge leaving only a shoulder behind. Then I would make an internal sleeve for the manifold just long enough to get a clean, flush, surface contact between the pipe and manifold, the sleeve would be a necessary filler in the manifold to prevent the exhaust gasses from getting to the coupler and melting it. At the moment that is how it is set up but I fear the movement on hard landings will shear the coupler anyway. Keeping that in mind at the time I also decided to make a pair of new o-ring grooved spigots. The outer groove will be for the only o-ring as I plan to only use one. The inner groove will be the welding groove to fill in and get a solid spigot. If the o-ring groove gets damaged again, it will take a lot more effort to break the spigot off. After seeing the Riva freeride pipe, and how they do not use o-rings at all, I feel like this will be a suitable balance between the two methods. Most likely I will just stick to the B pipe for its reliability but I hate seeing my favorite pipe sitting around useless. I'd rather know it can be put back on and ran again then to see it in decommissioned status. As mentioned to maddmatt, I have no intentions of letting this one go :D but the Coffman pipe just might have to to offset the expense of the new B pipe. I will try to post pics when I can of the tail section modification in the near future.

Well, I would like to try the b pipe at least. I have 2/3 of it now. I like the Coffman, but just want to try the b pipe. Quite a few people I know running b pipes say I will like it, and about half of the parts are here for me to use for free so I figured I should give it a chance at least.
 
Thanks BK, I appreciate ya brother. I understand the question being asked, and it's not so much about fixing anything in regards to changing pipes, but rather looking for a good alternative. If not for having the Coffman's, my ski would have been down for a while longer than I prefer, given that the season up here is quite limited it was a real relief to know I was not down and out for long. Will my corrective actiions be a permanent fix and no follow up issues with the dry pipe? I have no idea, so I suppose this is a fix unto its own having a pipe that is not damaged. Yes the two pipes are lower in RPM under peak load (the Coffman's is from experience, the b pipe is by researching only) but having not tried a b pipe on my ski, much less to say a well tuned one, I have no idea if I just might like where the power comes on. It does get expensive doing this testing of hardware but isn't that how you determine what setup you like the most? I like testing different pipes for sure, it's just who I am I guess. Maybe I will like how the b pipe performs, I don't know to give an experienced answer but I have it now so win lose or draw, the search for a good alternative will happen. Thanks for asking though, I'm sure there were others thinking the same thing, it's all good :)
