Project Board / Re: 1977 400F2 first restore project
« on: November 07, 2020, 06:06:57 PM »
Indicators working again, just needed a battery charge. Shiny bits; Sorry this is going to be a bit long winded. Because I had to replace the clutch casing, and the only one available has been chromed, and most of the chrome has peeled off, this has got me thinking about a few points regarding shiny bits. Also how much I don't know. I had thought that my original clutch case was chromed but now I believe it is actually polished aluminium. So then must be the cover on the other side of the bike which hides the starter motor and sprocket. Whereas the points cover is chrome plated steel? Same for the chain guard? This came to light when I asked for a quote to chrome my new clutch case, as it's obvious I can't shift all of the chrome off it. The chromer said he wouldn't chrome aluminium, but he gave me a quote to strip the chrome, £30, and also if needed, polishing for another £30. This seems the right way to go as mentioned above it would then match the left hand cover which, I believe is polished. So now I'm thinking, I have no idea what was standard for these bikes. Was it polished aluminium and chromed steel or some other combination. If you've managed to make sense of all this well done and thanks for reading. Any insights would be appreciated. Link to my existing shiny bits below. First image is the original clutch cover and second is the chromed replacement.

Here is my battery set up. There was no battery with the bike. I bought it from Tayna batteries.

Do it. Avoid nightfall and mud. Have a mirror though as you'll need to look out for the rozzers.

This was owned from new by a mate of mine who I've got back in touch with since I started my project. It was last MOT'd in 2019 @30,600 miles so there has to be a chance someone on the forum owns it. Fingers crossed. If it's yours I can tell you how it came by a broken fin!

Thanks Ted. I haven't installed an inline filter. I did fit a new filter in the tank as it was part of the service kit from DS as the tap was leaking. I think you did the same? So far the tap is leak free and it turns fine. I did fit the 2 O rings as recommended by DS. So the list of what I have done so far is:
Fix leaking fuel tap
Evaporust treat the tank
Fit a new battery
Get the front brake "working", more to do there
Replace the broken clutch case with a second hand one
Install replacement clutch actuator thrust bearings
Get the indicators working, they have since stopped so more to there also!
Go for a test ride

I'd like to go for another test ride to get more of a feel for how the the bike is running before starting to take it to bits, so priorities now are, improve front brake, new pads and adjust the gap between the floating pad and the disc, something I haven't got my head around yet. Get the indicators working again. Fit a mirror on the rhs will means tapping out the master cylinder mirror stem hole. If I fudge that up then I'll probably buy the DS Master Cylinder which is cheap. I'm pretty sure both mirrors are original however the right hand one is missing most of it's thread, it was in the MC. It's a shame as the left hand one is in amazing condition for something so old.

Red Letter Day. Engine started after just 3 attempts. Soon warms up and choke reduced then off after a very short time. So far so good. After running for a couple of minutes revs' started to rise up to 3000. Switch off, try again, same issue. Start think that the helmet laying on the floor ready is hopelessly optimistic. I did have the bike running a month ago and hadn't touched anything that would directly affect things. Head scratch and start thinking well here's the first sign that I'm going to have to get serious with the carb's and then thought let's try the idle screw and holy moly a less than a quarter turn and the tick over settled down fine. Helmet on let's go. Tried the brakes and wow the back one locks the wheel easily on our recently resurfaced street. Just as well because the front brake is, struggling for the right words, ineffective, hopeless, only for the brave etc. Anyway brakes tested and onto the main road with no dramas, rode through all the gears up and down, kept the rev's below 5000. Front end somewhat bouncy but overall one of those smile on your face moments. Checked the voltage on my return and it was giving 14.5v at about 1500  - 2000 rpm. Relax for a bit and chew on what to do next. Remember to turn petrol tap off. Have been reading engine full of fuel and seized up thread. I'll just go and check that tap is still off.

Back from the road test, oil catcher at the ready.

Why would you want to know the compression, assuming it runs OK.

I can sometimes be a bit anally retentive.

Sean I can see that you have a double spring on there. I think I need to scour the garage floor.

Refitted the clutch thrust bearing with a replacement cage and shiny ball bearings. I've left one screw out where the case was broken as the thread is damaged in the case. Measured the depth at 16mm so I don't think there is any broken screw in there, however I'd rather look at trying to fix the thread when the engine is apart. Even though I only plan a very short test ride I can't bring myself to pour the old oil back in so I've managed to find 5L of 10W 40 at £10 on amazon so I'll put that in hopefully tomorrow, swill the tank with some petrol then refit. Then I will have run out of excuses to go for a ride.

Should I expect any difficulty getting fuel through to carbs as the fuel pipe won't be full after having the tank removed for 3 weeks?

Next question, assuming it runs OK, should I check compressions? I feel that It would make sense and would be a no brainer if I had a compression tester. Can anyone recommend one? There are some for under £20 on Amazon and a shedload on Ebay, many of which look identical with numerous brand names, often in the same red plastic box, mostly around £10.

Took the first dowel out using a drill chuck and bolt through it, it came out stupidly easy as it turns out. The chuck did squash the dowel a little so if I do that again, I'll wrap the screw in tape or perhaps find a close fitting drill bit. Anyhow, suitably confident that these dowels might not be in tight I removed the next one with pliers with little effort and no damage. Got the kick start oil seal out in semi reasonable condition as it is going to be used in the new case just for a short run before the engine strip down. The replacement case already had a seal in it where the clutch thrust bolt comes through. The ball bearings are very knackered so I've sourced a replacement from Julie.

Removed the damaged clutch cover ready to replace it with one from 400/4 bits. Sods law that the case that came off left one dowel in the crank case whereas the replacement has a dowel in that position, with the opposite for the other dowel. Are there any tips for pulling these out without causing damage to them?

Misc / Open / Re: Frame Painting is Powder Coating best?
« on: October 30, 2020, 04:27:17 PM »
I'm still on the fence with this decision. I enjoy spraying paint on stuff and even the prep, so I suppose that's my default position. Also I'm in this to fill the hours since I retired rather than have someone else do it for me and have it done quickly. That said, I am interested in ball park figures for the cost of powder coating vs DIY spraying with rattle cans. My guess is that powder coating has a wide price range, given that there is a wide range of quality of outcome as described above.

My plan A involved using a £3 3V aquarium pump with a stream of Evaporust directed over the upper part of the tank, the bit that rises up over the frame and is the hardest part to cover with the treatment. Whichever way you position the 14L tank it's impossible to cover with 5L of liquid. Very Heath Robinson and eventually I gave up, choosing instead to put 20kg of washed, dried pea gravel in to occupy the space. Then the 5L of liquid sat above the ridge with the tank tilted slightly forward. I didn't slosh the gravel around I just used it to occupy volume. I emptied the tank after 3 days then washed out with water, dried using my bike/dog dryer. Then I put in a mix of petrol and oil for temporary protection as I intend to use the tank soon for a road test. When I take the tank off prior to restoration I'll probably protect it with ACF50 as this stuff really sticks.
