I'ts alive. I don't normally like first time startup videos as i feel it jinxes things but i did it anyway and sure enough i was jinxed got a ohh noo feeling when it wouldn't rev and cut out ? my temporary fuel tank was empty so all's good With fuel in it seemed to run better sounds real quiet and ticks over so much smoother, it used to have a lumpy tick over i'm thinking the carb balancing has fixed that, hopefully it will still be ok after a run

Nice recovery @MooN its such a good feeling when snapped things come out

As a rough description the part I've circled in the photo has a plunger in it which is pushed up by a spring and the space below it is filled with oil as it advances when the chain and guides wear, The oil stops the plunger from moving back once its advanced so keeps the chain tight, the oil in this part will only come out if you turn the tensioner upside down. New oil runs over this part when the engine is running but it does not replace the oil that's in there so hoping cleaning it out will fix it otherwise it's £150 for a new one

Got the engine back together tonight also adjusted some of the valve clearances which was quite time consuming without the proper tool for the job so just the rocker cover to go on and refill the cooling system tomorrow and then i'll find out if my efforts were worth it @Bruce the crows foot worked great for torquing up the cam sprocket bolts, would have had to remove the cam covers to do it with a socket

I've moved to the cam chain tensioner tonight. first job was to remove the cooling system thermostat and fill point relatively simple job which involved undoing some jubilee clips and then covering my garage carpets and socks in antifreeze ffs. after moping everything up and a clean pair of socks this is what i took off Removing that lot gave me better access to the rocker cover looks a bit scary in there i don't think I've done this to a twin cam engine before Didn't take long to get at the cam chain tensioner and only had to remove one of the camshafts. But you have to remove the two R clips and push the pins out to free it from the cam chain while over the cam chain tunnel what could possibly go wrong ? Got it out without dropping anything into the engine but still have to put them back in tomorrow From what I've read the bottom cylindrical part of the cam chain tensioner in the photo below is full of oil and stops the cam chain tensioner plunger from returning once the spring advances it, but when you drain the oil from the bike that part never gets drained and it gets a bit sticky usually around 50,000 miles. So the whole point of this exercise is to flush it out and refill with new oil because as far as i'm aware the oil has been there from when the bike was new which makes it 28 years old. Last photo with the cam out really not looking forward to putting this back together tomorrow might have to get the workshop manual out looks a bit complicated ?

Dear god no did you eat them

I was also talking about when i started riding, there were some great mechanics about then not so much now as their either retired or dead and bike shops now seem to change parts until the problem is fixed instead of diagnosing whats wrong first
-
Lots of places to get the bike worked on around here i'm just too tight and i used to enjoy it but i am in Pedro's frame of mind now i just want stuff to work, I'm thinking of getting rid of the CB this year so i want it to work right but working on it makes me want to keep it Going to have a look at the cam chain tensioner next as they get a bit sticky on them at about 50000 miles and this bike is just past that and gets a cam chain rattle now and again fixed by stopping the engine and restarting

11°C over in Avonmouth today like a summers day -
I worked near there a few years ago and when googling the site which is on the river taf i found this comment in the reviews i think i posted it before somewhere thought it worth another read

I've been using theses for years and with the heated grips i can get through the winter with them as well but sadly cant get hold of them anymore and the nearest things to it a double the price https://www.ebay.co.uk/itm/Tech-7-Cyber-Summer-Motorcycle-Motorbike-Leather-Gloves-Black-Red-XS/132288563487?hash=item1ecd03491f:g:8CgAAOSwWhRZiY2h&var=431753948881

As I've posted before i had the carbs off the Big one a month or so ago to sort out the shit that got into the carbs and after putting it back together it was running sweet again, but after leaving it stand when i fired it up next it started pissing petrol all over my garage floor so yesterday i started the arduous job of stripping the carbs out again and found this red shit in the fuel lines You can see it in the hole where the fuel enters the carb in this photo This however had nothing to do with my leak it just happened to be in the holes where i needed to fit the new O rings on the T piece that the fuel pipe attached to so in one way it was a good job it leaked. After putting everything back together i had developed a new problem, when i revved the bike the revs wouldn't drop back down unless i held the throttle shut. This baffled me for a while and then i noticed that two of the carbs were not shutting all the way when i released the throttle. The carbs are in pairs with a link to join the two pairs together. When i split them down to replace the O rings i accidently trapped a spring in the linkage when putting them back together and that was holding the two carbs slightly open. I hooked the spring out and then spent the best past of an hour trying to find it, bloody thing had landed between the swing arm and the engine anyhow here it is And this is where it should to be So dreading taking the cards back off i thought i would have a go at getting it back in with them in place and i got it in after a few minutes faffing about what a bloody relief i really didn't want to remove the carbs again Because i had to back off a screw to get the spring back in it meant i had to try and balance the carbs and with only a two cylinder carb tune it wasn't going to be straight forward. The idea is the carbs are in pairs so i balance the pairs on cylinders 1 and 2 and then 3 and 4 first. Then i have to balance cylinders 1and 4 which will then balance all 4 carbs if that makes any sense 1 and two were a bit out but 3 and 4 were almost spot on 1 and 4 were way out which was what i was expecting as that was the adjustment screw i had to back right off to get the spring back in and when i dialed them in i had to drop the revs over a 1000rpm to get the tick over back so i think they were out before i started messing about. seems to be pretty good now but going to borrow a 4 cylinder carb tune to check it before i put it all back together to finish the job off properly

Yesterday it was -3°C and we had a sprinkling of snow on the ground and plenty of Ice Today snow all gone because of the rain and it's 6.5°C, It's supposed to be getting up to 15°C for next weekend ? -
I like the roads through the wooded area my type of road.? Would also like to hear the rattle of your bike as well on some of those roads instead of the music

I'm going to put something more aggressive on my Africa Twin when the tyres on it wear out but will probably never see dirt with them, i don't know why i just feel more comfortable with some knobs under me and of course the bike will look so much better
