I tend to agree with your last post Marronia, I fitted a new cam chain and guides when I had the engine down a couple of years back. I noticed the chain was noisier after adjusting when the engine was hot. I have the rocker cover off at the moment and checked the chain for play and was surprised by the amount of play. When undoing parts 19 the tensioner did lift part 5 slightly say 2 mm. I thought perhaps the rubber part 4 might be missing or damaged, but no, it is fine. So like you I intend loosen bolts 19 and increase the tension a little. To be honest it was n't very noisy but I like things to be as good as I can get it.

I do mine with a lowcost vacuum gauge after setting them on the bench by eye. My final tweak is to check the temperature of each exhaust header after warming up,I have one of those infra red devices. I found one running cooler than the other three so adjusted the height slightly.

I had a similar problem with the fuseholder, cleaning it cured the problem for a while but when it failed again a few months later I bought a new assembly from DS

I think you are right Yozzer get it to run first see how it runs /sounds. I bought a battery and oil and started it to find smoke and rattles, I'm glad I decided to strip down because the sump was full of gunge both chains required replacing and the valves required re-grinding, the headstock bearings were notchy, basically all the things you would expect as part of servicing needed checking. The loom should be ok. I replaced the bullets and sockets on the ends of all connectors because i had intermittent issues with the electrics. I removed all bits of wiring that didn't belong ( heated grips etc)

Hi Yozzer74 welcome to the 400 owners club.
If you are unfamiliar with the 400, then you could do worse than to spend a few hours reading through this forum in particular Nurse Julie's build.
I bought mine in 2016, even if you don't want to return it to prestine condition ( which I didn't) be prepared to spend at least £2k and a lot of time to make it run properly and be reliable and safe, you need to got through the bike completely.
I replaced the rings and one piston that was damaged ( pays to take the engine apart), it had 33K on the clock and the last Tax disk was 1998. I now get around 120 -125 compression using the same type of compression guage you mention. It will do 70 no problem up a hill.
I found lots of bodges, in the wiring and fuse box etc.
good luck

I'll get in touch when I have swapped them out, bear in mind i can't order stuff at the moment. I'm only doing the cam cover as they rust each year, I never throw owt away Julie. I was really trying to get people's opinions on using stainless.

Having got my bike out for service in the hope that I can ride it again soon, I notice that the fasteners holding the cam cover are starting to rust. I have not had these zinc coated when I restored it. I 'm thinking of replacing these bolts with stainless (with copper grease).
What are your feelings on the use of stainless

I'd be interested to know what members think about fitting crash bars to 400/4

I would be interested to know what members do to store there 400/4 over winter. I stop riding as soon as the gritters come out.
Do you drain the oil and remove the battery after coating brightwork with an oily rag or just throw a cover over it.

I had wobbly front brake lever. parts 224 225 on the above drawing. the hardened pin was missing. I made a pin from out of a chain cut to length. I managed to find the retaining 225 part which fits underneath from a box of bits supplied with the bike. Works fine now .

Check that all four pipes are the same temperature, I had one running cooler than the other three which I cured by adjusting the balance screw.

Forgive my ignorance, but I was under the false impression that the airscrew settings on these carbs was purely for adjusting the idle and slow running side of things. At 6000 rpm with wider throttle openings I wouldn't expect it to have much of an effect on the overall mixture.
I have set all my airscrews at 2 1/2 as per the book. It runs fine though lean. I will now re-examine the settings.
Could somebody put me right on this.

Thinking about security, I have a larger heavy chain and lock for the garage but i don't want to lug it around. I have a steering lock but no key. replacements are available from you know who. What I'm not sure of is how to get at this to replace it. There is a pin and small plate holding the lock assy. in place. Can anybody advise the best and least damaging to paintwork method of getting the thing out.
Answers on a postcard..
what other security options are available

My speedo reads 35mph when doing 30mph, I say this because I pass a camera in my car each day which I'm using for comparison. Can anybody suggest a company that can calibrate it for me.
