    Other Cell Phone/Tablet Cases & Accessories

    Stumbled across this website earlier today. Looks like they have cases/accessories for the vast majority of cell phones and tablets that are around today. Otter Box Defender Cases starting at $10, LifeProof Cases for $20, etc. I ordered a few to say the least. http://www.accessorystoreoutlet.com/

    Other Reason why I love xh20 :)

    Just came across this and want to make it perfectly clear that I was NOT post dumping in the thread linked to the first post. I'm not sure how it came across as me selling one for that price but it is what it is. I'm not that big of an a$$hole. Guess I will clearly state "I am offering you" when...

    300/440/550 550 reed Westcoast Cylinder Exhange?? Help Indentify?

    Looks like the early 550 reed motor from westcoast before kawi released their own. Looks to have the bridged exhaust port as well. Yes those are 750 reeds. I have one as well. Good power especially for a 550. Good luck finding sleeves if it needs them, took me over 6 months to find some. If the...

    650/X-2 new starter

    Pull your flywheel cover and remove your flywheel to inspect your bendix. Looks for missing teeth and check to see if the bendix is spinning out by hand.

    650/X-2 jet pump resealing?

    I use permatex black RTV. Really any waterproof RTV silicone will work, just don't go to cheap you do get what you pay for.

    300/440/550 JS440 motor rebuild in need of help

    They look pretty good. You'll need to measure them and see what milimeter they are at. 68.00mm is stock bore. As long as there isn't any big scratches or gouges that I can't see you will be able to use those cylinders. If your within tolerance of stock bore you should be able to hone those...

    The 550 will bolt right in and the 440 electronics will work. You would need a 550 manifold and exhaust and possibly a 550 intake a carb.

    300/440/550 JS440 motor rebuild in need of help

    Head, cylinders, pistons, crank, cases, no starter. Bolt on your own manifolds, carb, electrionics and go.

    Wouldn't hurt. You can buy 550 engines relatively cheap. I sell long blocks for $220+ shipping. Sent from my iPad using Tapatalk

    300/440/550 JS440 motor rebuild in need of help

    Most of the crust is from corrosion from water entering the head. A top end rebuild would be a good idea. To get your cylinders off soak the studs and cylinder is PB Blaster, Aero-Kroil or another rust inhibator. Take a rubber mallet and carefully hit the cylinder to break it free from the...
