    I'm not much in the way of a wrench per say, but from what little I know and more I've read, send your jugs out and have them bored. This will be alot less expensive to do. The shop will also fit your pistons as well. As far as the rest, you're gonna have to wait for someone else to chime in and offer some advice, that's all I got.:eek:

    You probably have a local machine shop that can do the work, check around, if not contact Bill or AMy at www.bishopsperformance.com, you can tell him I sent you but it won't save you money LOL

    Tear your motor down and send him the cyl, he can get the pistons, bore the cyl and fit the pistons into the cyl, then for install you simply tap them down just enough to slip the pins into them and clip them in. Makes it easy.

    I bought myself an extra set of cylinders off of ebay by doing a search on cylinders. That way I was able to have a shop bore them for me without having any downtime of using my own. Also it was nice knowing that if they screwed them up I still had my own.

    With a little mechanical knowledge and a service manual just about anyone can do the big bore on their own. Changing the cams is what takes the special tools and a little more skill. If in doubt pay an indy shop, its worth it if you don't already have a good set of tools. I will eventually be buying a set to pass around as a rental set.

    Personally I'm not crazy about the SE 203 cams. Many report not feeling any difference between those and stock. I went with the Andrews TW26 which are well suited for cruisers wanting lower end torque. The TW37 is another good choice if you are looking for more mid to upper torque/hp.

    I would agree S&S 570's or 37B's much better choice, Bill and Amy are good people and Bill does great work, you can get heads done and cyl bored with pistons installed, get the S&S cam change kit for changing cams has all the bearings you'll need Also jmo pick up a set of S&S travel limiters for your lifters, makes a great difference in setting up the pushrods (adj) and they really make the motor quiet.

    Pretty much the bottom of the barrel on cams JMO

    204's are better,
    ANdrews 21's or 26 even better
    37's need more compression but better
    S&S570's same as 37's

    JMO 37B's from andrews would be best for a 95 that is mild

    Big Bore Cams

    I put SE 211 cams in my road King with 95" kit. I installed SE High compression Heads and pistons and wound up with 103HP and 106 Lbs of torque. at 30,000 miles I lost an inner cam bearing and **** canned the engine.

    Moral of the story: If you change cams upgrade your cam bearings and support plate.

    The bearings should always be changed when doing a cam change. JMO.
