    wet jet CDI unit 70000-0641

    The Seadoo 587-720 does not use a separate pickup for the CDI , the 787 and 951 do but they are DC CDI . To the best of my knowledge, they operate like the Kawi 440-550-650 CDI systems do with a pulse from the stator .

    wet jet CDI unit 70000-0641

    Is this the Sno-stuff CDI box that some of them used or a NIppon Denso box , I know Wetjets used both Brut and Cuyuna engines in their skis.

    Erickson performance input...help

    You know I hate to say it but the Jet ski industry is about the only industry you could get away with those type of business practices. It all boils down to the turnover rate , while I have no idea what the turnover rate is in the standup community on sitdowns I have determined it to be every...

He also started an E-sports...

    Super Jet The Poor Panty Dropper

    Personally I think if you only have 150 with an ADA head installed that top end is tired , at the very least pull it apart and find out why , this is assuming that your compression gauge is accurate of course, if you don't trust it borrow or rent one and check it again. As is it's more of a...

    Not an SBT , not even a watercraft engine, reeds on the bottom mean outboard powerhead as for being faked yeah probably so.

    Here is the part I don't get , he has a lathe but he is beating on the pipe with a hatchet ? Everyone of these vids I watch in undeveloped countries they all have lathes, I guess a ball peen hammer is like gold over there I wonder if they would like to make a trade ?

    They do a lot of weird stuff in third world countries, apparently new parts are hard to get in some places . The guy that used to bore my cylinders showed me something that they do over there on pistons. The pistons are of course cam ground , bigger at the bottom than at the top, so you take...

    What are my fuel options?

    Av gas is the probably the most stable high octane fuel , some race , especially oxygenated race fuel loses octane the moment you pour it out of the stainless steel container into your fuel jug or tank , as you said E85 absorbs water so limited time you can use it as well plus I would think...

    Paint how to thread

    This is exactly why I don't do customer paint and bodywork anymore , most customers think you are trying to rip them off, they have no idea what is actually involved in something like this , since it is mine it doesn't matter how long it takes , I will make enough money in the end to cover it.

    Paint how to thread

    It's been a minute but on stuff like this I tend to take my time , sanding all the little nooks and crannies on a hull like this is a b!tch [plain and simple , just take a small spot at a time and sooner or later it will all be done. All of the red menace has been removed , it's down to the...
