    There is no doubt that what you say is true except possibly the bent over part. I have not done this and still don't really see it all the way through in my mind, but as I stated above "you" seem to have a very nice tool to perform this task and I am not speaking of the bent over part either. Being a novice I am always trying to improve what little mechanical skill I have and understand others views on maintaining their norton's. If anyone does this again make a video, I'd love to watch and again I am not speaking about the bent over part..... :wink:

    Reactivate!

    Anyone got a picture of the referenced spring tool? I have several for auto engines and am quite familiar with the procedure but a picture of the necessary tool will keep me from inventing one :D

    Hi Jim,

    I've sent you an email, I have a PDF I can send to you with pictures & instructions on how to build & use a VSR tool. A forum member sent this to me (sorry for who it was :oops: ) the pictures, I believe, are from Ludwig as was the original idea.

    I built & used the tool & it works!!

    Is there any way to post it so it stays available in a permanent fashion?

    I'm assuming Jean means the lidwig tool picture, I'd like to see it too, I missed that one, I have most of his others.

    This thread seems a good place to keep all the valve spring compression tool methods. The rocker plate mod method seems a pretty nice one to try, combined with Ludwig's method for holding valve up and releasing the rocker by using a temporary thin rod in place of the spindle. Attaching Ludwig's photo tutorial PDF....

    I've used Ludwig's method to check & replace the valve oil seal BUT ensure you stuff plenty of rags down the pushrod tunnels!! I didn't and on my third attempt replacing a seal I lost one of the collets down the tunnel.

    2 days later, using magnetic probes, suction etc. etc. I had to bite the bullet & remove the head!!!

    I'm researching this as noted white/grey smoke from Left side pipe when blipping throttle from idle on a fully warmed engine. I suspect it's the 44+ year old rubber seal on intake valve.

    If the seals are really 44 years old then everything there is 44 years old. Maybe time to take a look at everything by removing the head.

    Ludwig: I've read your photo tutorial closely but I am not clear on what is done to make the threaded bolt/rod going into the rocker in place of the adjuster bolt. Your picture shows a longer, rhinner threaded section then a wider one. How is that made?

    Yes, I've been seriously considering that as a better option. Bike only had 8300 miles on original clock when I acquired it 10 months ago. and I've now put 3000 miles on it before the smoke appeared. Watched a YouTube of a guy doing the head pull/replacement on a 750. He had decades of motorcycle work experience but not vintage brits. He really struggled with the refit single handed.

    Well, my efforts to secure a full thread M7 bolt of suitable length for Ludwig's tool (50-60mm) have fallen flat. No local fastener specialist carries M7. Ones I can find online are hugely $$$ to ship $0.85 bolt and $25 shipping) or 1.5 months to arrive from China.
    So, I'm going with the alternative tool depicted top of this thread, making a flat plate and using rocker adjuster to thread plate to rocker arm, then compress spring with two bolts through the plate.

    Did you look for a piece of all- thread (threaded rod) instead of a long bolt?

    Yup...local fastener specialist stated M7 not a standard and had nothing. Local hardware shops, no M7 bolts and only SAE all thread.
    I do see M7 in use for bicycle fittings online, but these are typically under 15 mm long.
    @ludwig shows in his pdf tutorial a long bolt/all thread cobbled to a stock adjuster to achieve the rocker. Connection, but no details given as to how those to pieces were attached and I do not have a spare adjuster to sacrifice.

    I made up a plate setup that seems be working well, no need for long M7 as it uses the adjuster nut and stud to hold plate to rocker. I need to go pick up some better material 1/4" side bolts for it. The soft metal ones I tested with are deforming a bit.

    Tornado :
    you do not really need M 7 .
    I only suggested it as an alternative .
    I know M7x1 is not very common in your part of the world , but neither is the correct ( 9/32 BSF ? ) thread .
    You can cut the thread 26 TPI , or 1 mm .. ( die , lathe ..) drill and tap an old adjuster bolt , or any odd bolt that fits , weld an extention ... many ways to skin a cat .

    use your imagination .

    Thx Ludwig. Unfortunately I don't have required taps/dies and no access to lathe or welder so I'm proceeding with the alternative tool using a plate bolted to top of rocker head via the adjuster. Seems to be doing the trick but I need to fetch a few more things before completely doing the job.

    New Kibblewhite Viton seals on the way.

    FWIW, (and admittedly, not much), I just don't see the point in replacing valve seals without pulling the head, checking valves guides and valves and re-seating/lapping the valves at minimum.

    I just don't see it as that much work but again, that's just me...
