    I have considered a SV650 engine swap. There are many more of those available. I've wondered what would have to be done to get it to run well. Swap Cam shafts and use the DL fuel management?
    Or try to get SV ECM and throttle bodies?

    Also around Christmas time a crashed 2011 DL650 with 9000 miles came up at a nearby insurance auction house. I bid on it, but wasn't willing to pay as much as someone else. I think in the end it went for nearly $2000. Seemed like a lot for a crashed and unable to title bike, but the motor and rear end looked in tact.

    Good reason to go check out the thread at the Vstrom.info site. Even though the transplant was for the liter bike I'm guessing that the process would be similar. John, if I remember correctly, salvaged most of the electronics and peripherals as well as the engine. It was a non-trivial exercise but he seemed to be pretty pleased with the outcome.

    Well I'm have a new plan of attack now.

    I cleaned up and started measuring everything.....
    So far all everything is measuing excellent.

    I did the old mineral spirits leak check on the valves. They held fluid for well over an hour. I left it overnight and the rear cyl. lost some fluid, the front none. I've decided I'm not going to mess with the heads. I might put new valve stem seals on.

    Partially lazy, partially cheap I'm going to put in new cam chains, hone the cylinders and re-ring the pistons, put it back together and go.

    You should also lap the valves. Just a little bit of grinding to get them a bit better seal.

    Don't the cylinders have some sort of nikasil coating? Not sure if honing is gonna fuck with that or not - anyone?

    Later model v-stroms do have nikasil or suzuki's version of it. My 2004 does not. I'm no expert on it but I believe nikasil usually gets a deglazing with aluminium oxide.

    Last night I ordered a flex-hone in the proper size, new cam chains, and the motion pro tool to remove the magneto/alternator rotor. I tried with the snap-on standard gear puller, but it wasn't budging with gentle nudges and I didn't want to wreck anything.

    Today I'll take a good look at the heads

    My 2007 Weestrom does not. It's possible the newer bikes with the gladius motor have it. Easy enough to check, since nikasil is a coating put onto aluminum, if your cylinder has a steel sleeve, you're good to hone/bore as you please.

    All V-Stroms have SCEM coated steel liners according to the features list. Suzuki Composite Electrochemical Material is a nickel phosphorus-silicon-carbide proprietary coating.

    Edit: After another look, I'm going to take that back, See post #33 here.

    Geez and here I thought one of the reason to have those coatings was to be able to reduce weight by deleting the steel liners?

    I just did a Google search on SCEM.
    Didn't really come up with much. There are claims on wikipedia that the dl650 has it, but I don't think mine does. Perhaps the gladius motor and probably the 2012+ Dl650 do. Now I'm wondering if I should deglaze the cylinders.......

    I did start cleaning up the heads, valves and seats today. Amazing deposits of carbon and burnt oil. I suspect thats where my vibration and lack of power was coming from. Either preignition from the deposits, or low compression from crud in the seats.

    After reading about the hard coating on the valves, i was afraid to lap them even. I removed the valves to clean up carbon built up on the stems. After the clean-up I checked the fitment with Prussian Blue. They checked good.

    Suzuki has included SCEM coating in the published features of all models of V-Strom. Many people, including me, assumed such a coating would be applied directly to the aluminum casting and figured it had to be wrong because the engines obviously have iron or steel liners. The fact is there is no reason a plasma splatter coating like SCEM or Nikasil can't be applied to a liner. Ergo, I figured the coating had to be there and was applied to the liner.

    On the other hand, I just now checked Suzukicycles.com and the reference to SCEM on the DL1000 includes weight saving in the SCEM treatment which makes no sense if it was applied to a liner. A look at the features pages of the 2011, 2012 and 2013 DL650 shows the SCEM reference is gone. Knowing Suzuki has published totally wrong information before, like some torque settings in service manuals and the accessory page info that the DL650 knuckle guard kit will also fit the DL1000, I'm going back to thinking the SCEM reference is just wrong.

    Interesting that the 650 uses a steel liner and I know the SV 1000 uses the plated coating on aluminum.

    I looked in my Gladius service manual and didn't see anything about a SCEM coating on the cylinders. :hmmmmm

    Well the dl650 may or may not have the SCEM coating. Greywolf, don't change on my account, I don't know.
    I do know my cylinder do have a iron liner, and after talking to a mechanic here that was formerly a powersports mechanic with a little knowledge of such things. I'll deglaze the clyinders as planned.
    I'll continue to not know whether I have SCEM.
    Kinda sounds dirty (SCEM) :lol3

    cylinders are cleaned and put back together. I will replace the valve seals, but I put it back together so as not to mix up part locations. I'm not always very organized.

    The alternator rotor removal tool arrived today. I got the pesky thing off. I admit, I'm not ever going to be a competitor for the worlds strongest man competition, but that was tight. Now after I got it off, one magnetic sector has a fracture.

    I can only it think that perhaps I dropped a tool or it was there before I took it apart.

    My new cam chains haven't arrived yet, but I'm guessing this isn't normal. This is the front and worst chain. UnTRIUMPHant.

    Well, I'm still alive and have been making slight progress on my project. Here's what has been happening. After I finished measuring everything, I found the Front cylinder valve guides were worn past the limits.

    I made a tool out of an old propeller bolt to push out the guides (and install new ones) I shouldn't admit my crude methods, but I turned it down by chucking it into a hand drill and turning it against my bench grinder, then finished it up by turning it against a file.

    I hit them with a hammer a few times, but that seemed futile so I pushed them out with a press.

    [​IMG]

    I ordered the suzuki tools to ream the oversized hole for the new guides and to clean up the hole for the valve stem. They haven't arrived yet. I'm also still waiting for a gasket set, piston rings and the new guides.

    Today I assembled the rear head with new valve seals. Aren't they pretty

    [​IMG]

    I received t a generator rotor this week, off a SV. (ebay)
    So I reassembled the starter clutch and rotor, with the new front cam chain and then also the rear chain, clutch.

    It's been slow going, but I'm not in a hurry. This is what it looked like out my back door this morning. Nearly the middle of April and we have only had a few days above freezing and a couple feet of snow. YUUK:puke1

    Also I don't really need the suzuki until a small two-up trip in July. I have the KTM to get me about.

    DL1000 and DL650 share the frame, only difference are the engine mounts, which bolt on to the frame...

    That means fitting the 1000cc engine into the DL650 if a piece of cake, if you get the DL1000 engine mounts. Getting everything to work will be a PITA, as you basically need the wiring harness and ECU of the SV1K on the DL, and the wiring harness will need a lot of work to fit.


    As fof the issue at hand, it's quite common for the 650s to burn oil as they get older, valve guides wear. If you're replacing the cam chains, don't skim and replace the cam chain guides too!

    Thanks for posting this, I did admittedly sell my old DL 650 when the oil consumption got annoying, it's interesting that my guess as to the cause of the oil consumption (worn valve guides/ seals) was probably correct.
