    ok,thanks guys.

    my plan of action is............

    check valve timing
    check valve clearance
    check deco setting
    fix deco lever not popping back.

    report back.

    how does that sound?

    Well, no point in tryng (CDI - it got electronic ignition advancer controller), and you have no suitable contol opening for that. It's either works or not :)
    To check valve timing it is enough to take central bolt-plug from left casing cover and rockers cover (comes out together with rockers BTW) and check marks.

    For igintion best is to just follow troubleshooting of all ignition chain as per DR workshop manual. Drop me your email address I'll email it to you. I have sent it to one of DRers in the past and still have it in my mail, so can forward.

    You can't check timing with a timing light. Most bikes have fixed timing, it is not adjustable (at least not in the way a car's timing is adjustable). The only way to adjust the timing on a bike is to change the relationship between the cam and the crank by moving the timing chain on the sprokets. To check the timing you need to remove the cover on the left engine case (round aluminum with slot in it) and put a socket on the nut and turn the motor (counterclockwise I believe) while looking to see the timing marks. You need to see that the piston is at TDC (on the compression stroke) when the TDC marks are aligned in the hole. You also want to have your valve inspection covers off so that you can see that the valves are closed at TDC on the compression stroke and that they open and close correctly. You'll also be able to check the functioning of the decompression mechanism through the exhaust valve inspection cover.

    (Edited, I was mixing up my bikes DR has only one hole in side cover)

    Email sent.

    I agree with what ppe172 mentioned, but just to add - if you take off head cover you can see marks on camshaft "flange". Those supposed to line up with surface of the head when you align marks you see through that bolt/plug thingy on left case cover. So, if you want to check that your timing is PERFECT you can do it this way, if you want to be sure you just OK you can check through inspection/valve clearance adjustment opnings in head cover. If you will take head cover off you will have to use sealant to put it back (standard way for DR) and re-adjust valve clearances.

    Still, I'd check fuelling and electrics first. It's way too easy even for wohever did it in the past to set valve timing right, but it is way more tricky to ensure they did not mess up electrics or that fuelling is correct.

    WOW !!

    We seem to have grown to some kind of "critical mass" here.

    Our gravitational field has increased to the point that we're attracting orbiting bodies from far afield and at an increasing rate. 800 Rider is going to be a busy guy.


    Maybe it should be the International DR Big "Blackhole" Club

    I have the possibility to purchase a rolling chassis of a KTM lc4.
    I also have a dr750 in pieces.
    The KTM cannot be used as it has been written off.
    I have also been insipred by Lukas project, in fitting an other engine to the LC4 rolling chassis.
    Here comes the dodgy question :wink:

    is it possible to rivet the suzuki frame vin to the KTM frame without it being too obvious?

    Yes. :) But you know we going to treat you as defector to evil side? :lol3

    No, seriously - I think it is supercool idea! I toyed with it too - with all my respect to LC4 640 (great machine) there is no shortage of LC4s with engine in pieces....

    Can you imagine riding it into crowd of KTMers?

    "what's that?"
    "that is new secretely developed LC5 KTM. 750 cc..." oops, no, lets do it KTM style "LC5 740 Adventure guys. Yea, it goes OK...better than LC4 " :rofl
