    Bung welder in FL? and more advice...

    I live in Fort Pierce FL and I am hoping to find one of our resident bung-welding experts somewhere close by.

    I read somewhere that speedskixp does these. Can anyone clue me in on what parts I need to buy...bung, which o2, etc? It would be cool if there was a writeup on removing the j-pipe...although...it looks pretty freaking simple.

    After getting some great tech tips here in another thread, I am ordering up the following parts on Monday from Jerry (thanks again for the expert advice you guys volunteered ):

    - Sea Doo X Model Supercharger
    - Fizzle 4" air intake kit
    - I also found the injectors I wanted (Ford Racing Bosch 42 pound Fuel Injectors M-9593-F302) and I will be ordering those as well.

    Other than a 13/18 solas and a SS wear ring (thanks Jerry) I am 100% stock. However, since I have all the tools I need (I think) to work on the boat and I am convinced that I can get really good advice here, I am going to try and do all the upgrades myself.

    If I was just installing the x-charger and the 42lb injectors, I would not be concerned about running too lean. After the advice I got here from you guys I am sold that I will not be running lean at WOT with this setup.

    However, since I am going to upgrade the intake to a 4", I am concerned that if I run the boat in colder water/weather (like now), I may get too lean and BLOW IT UP!! I would reeeeeeeeeeeally like to avoid that.

    I also want to make wure I am not running rich during idle and while cruising around.

    Anyway, after some reading, it seems that I need to have a bung welded to j-pipe so that I can screw in an 02 sensor and attach something called an LM-2 , and then start up the boat and monitor the fuel-air to see the ratio. Not that I could DO ANYTHING about it...mind you.

    I figure I should do this right and measure the fuel-air stock so I can see how lean/rich I am running in comparison.

    Am I over-doing and over-thinking this? Or, am I pointed in the right direction?

    Order a stainless steel bung from Dynotune or Innovate, and send the pipe over to Jim (speedskixp). He's in Venice, and does a nice job with these

    Here's a picture of one that Jim did...

    I have O2 bungs in stock. Drop me a PM if you need one and I may convince Tantrum to weld it in your J-Pipe. He's done several.

    Also looking to do this...Can the bung be welded while the J-pipe is on ski.

    Pain in the butt to remove J-pipe and put it back on with Riva shorty box there...
    Some of you know what I mean....

    No... you will need to pull the pipe. Once you have it off, you can chop a few inches off the end of the pipe to get it back in easier.

    Also u can pull your exhaust manifold, and drill and tap it for the o2 sensor next to the top rear water fitting. Breon, and I have it on our setups

    Just a little word of advice here... do not attempt to do this by hand! There is very little room there for error. A good mill along with someone that knows how to use it is required for this job.
