Ccts swapped! Video added

[VTRDark]

I have not had no luck gaining access from the front. The crossbar on the frame seems to get in the way. From the side is a possibility but I see that as being fiddly and more time consuming than removing the carbs. Maybe I don't have the right tool for the job and also working out on the deck (Abba Stand) in the elements doesn't help.

Back to the OP

There is a bit more noise than before, seems more clattery, but that could be in my head as I'm actually listening for noises now!

It would help to know if it was this bad before any work was started but running with MCCT's does change the sound characteristics especially when the engine is cold but not like that. From listening to the first Vid there is definitely more tapping than normal. The second vid it can't be heard so well.

It reminds me of when I first got my Storm and done mine. I made a boo boo with the timing. Basically when going from the rear cylinder on the compression stroke (RT) I did not turn the crank a full 1.25 turns anticlockwise and stop on the front compression stroke (FT). Going from the rear (RT) to the front (FT) the FT mark should pass the inspection window once and then stop the second time it comes around. This is 1.25 turns!!! I stopped at the first time it appeared in the inspection window thinking it was right. I did not check the position of the front cam lobes or stick a finger in the plug hole to verify it was on the compression stroke. I started the bike like this and there was a loud tapping noise similar to yours. The bike rode, but I only went a small distance before realising that this was not right as it was noisy, so stripped everything down and started again from the beginning. This time removing both cam covers. I was lucky not to cause any damage.

I'm not saying this is where your problem is but it's something to be aware of. If your sure the sound is coming from the head area of the bike and not from somewhere else. I would be Stripping things down and double checking everything. Follow the MCCT thread in my signature, remove both cam covers, check position of cam lobes and their alignment, adjust as necessary and while your in there it's worth checking the valve clearances.

But hold on...before you do that as it's a fair bit of work , there is another possibility here. Carb slide bouncing around. Have a read through the following thread including copying and pasting the youtube link to make a noise comparison.

weird noise!!!

Carl, I took it all apart again following your guide to the letter and all the timing was spot on. I measured slack to 7mm front and back and put it all back together. It still makes a ticking noise, seems to be coming from just above the clutch housing, closer to the rear pot, but it doesn't seem to be anything that affects the way the engine runs. I took it for a good blast the other day and it pulls well in all gears all the way through the revs.
Things it could've been that I sorted now are the front breather wasn't quite seated on the airbox, and the carb screws weren't tight, so I guess it could've been blowing from either of those places. Also the exhaust join to the link pipe under the rear shock has a slight leak in it and could be popping when the bike is running.
Thanks

Replace the graphite seal in the link pipe exhaust and clamp* it all back up as air leaks can cause quite a rattle.

* Recommend Mikalor Supra fully stainless W4 clamps.

I'll give that a try next week.
