Thanks for the response Roseland, Ya its seems that 150 main and 120-125 pilot are used quite often for my set up with a b-pipe, I am concerned about the difference with the C4 chamber. I have heard it produces a higher trapping pressure than a b-pipe, and has different water needs. Ya def...

Ya it is currently at 20 tho, I was expecting to be a bit close because I had it decked but I was hoping for more like 35-40... not 20.. I think at max rpm there would be some metal to metal contact.. I am going to machine them to get between 35 and 40 tho, have you heard that going bellow 40...

Hey there, I am about to put my superjet back together and I was wondering if anyone had any insight on the carb and pipe settings that are needed to make a C4 chamber run well. I cannot seem to find too much info from people that are running them, I hope someone with a similar setup to mine...

I like the idea of being able to reproduce more after you prove it out. That is for sure a selling point for using a mold... and it would likely just be better all around. I just wanted to do the lost foam so it would be fast and less labor intensive. I am not sure that vinyl ester is much...

Awesome sounding project. I agree, I think that fuel tanks could look way better and use space more effectively. I was thinking about using a lost foam method to make the tank. Basically shape the tank how I want it in pink Styrofoam or any foam that can melted with a solvent and not epoxy...

More booth making... The hull felt pretty heavy... so I pulled out the pump and peeled off the old turf, and weighed it... Anybody know what impeller this might be? All stripped it still weighed in at around 160-170 lbs... soooo I then had the great idea of de-foaming...

Ok so now that all the parts were blasted and clean, @Parsonsjb88 and I got together all the parts and sorted out colors and sent them out. Time to disassemble the rest of the ski and get ready to fix the small crack and re-turf (that was the plan at this time...) ^ you can see one...

I pulled out the Bendix insert from the cases because it was cracked, I tapped the inside then pulled it out with a bolt Then went to walmart and bought a bunch of baking soda, to soda blast everything with sensitive surfaces. I used this method to clean the carb interior/exterior...

Ok back to build stuff... Some pics of carb disassembly and choke removal.

I started this thread a while back to get some inspiration for powder coating my 701 parts. Thought I would post some pics of where I am now... I am quite pleased with it so far, I still need to get the rest of it together. The green and blue one belongs to @Parsonsjb88

Cool, is it made to look like stock tank?

This is very true, I will be there for sure. Just the ski situation that sucks... I started this project way too late knowing sortie would be a hard deadline... So my girlfriend and I bought a X2 just to have something fun to ride... then just a bit ago it crapped out... still have not had time...

...I hope it will be rad, and I will keep this updated... after I catch it up... hah it is taking me long enough to do that. It is not looking too good for this summer, running out if time. I want to have it done for sortie sooo bad

Cylinder porting up next... I didn't do too much on the transfers or boost. I didn't even match them all the way to the sleeves, I was worried about controlling the roof angles and staying even. I have never done any porting before so I figured I wouldn't dive in too deep. I spent most of my...

Thanks for the response Vumad, I think running a bladder would work, but I can't seem to find a good bladder in the 3-5 gal range that work with my fabrication plan. I plan on sticking with ethanol free fuel for sure, and I am using epoxy for the resin, it would seem that epoxy is quite...

Ya I should drop the tank in first and see how bad it is, I need to get my build thread up to where I am now so you can see the rocker and such, I am way ahead of the thread at the moment, rocker isn't about to change (already glassed for the most part) and the c4 pipe is in my hands already...

Biggest reason for me is that I don't think I can fit my stock tank back in my ski with the rocker and exhaust changes I am making. I have a bunch of carbon and glass handy and i like to try new things, I want to maybe include the battery and ebox into the tank...

Ya? Cool, I wonder if many are still around and what experiences people have had with them. I am trying to figure out the best way to stop leaks and material degradation. It looks like Caswell tank sealer should do the trick.

Has any body made a carbon and/or glass fuel tank?

Next I moved to the cases. I couldn't find too many pictures of ported 61x cases so I just did what I felt would work. Started with digging out some channels for the transfers, Then marked what I needed to clear for the gasket matching, The last three pics are...
