I think the slides are in the wrong bodies

Ran the bike today and it all seems great, put the vacuum gauge on the carbs when I got home and I get this;

#3 does show 10-15cmHg when I blip the throttle but otherwise, adjusting that slide just increases or decreases all the others by variable amounts.

Plugs are new, air flow upto the carbs is sealed so it could be a leak on the other side (the boots?). I did swap the vacuum tubes over to make sure that #3 tube and the carb tune wasn’t faulty. If it wasn’t for the vacuum gauge I just wouldn’t have known anything was wrong as the running response and idle seemed good. Well to my untrained mechanical brain anyway.

Nurse Julie:
Are all the exhaust headers the same temperature, ie, equally bloody hot when you've been riding?

I will check the next time
Thanks

Oddjob:
No Vacuum to that cylinder, which means a massive loss somewhere. Check the valves on that cylinder, remove tappet covers and check they are first of all going up and down as the engine turns over. Either there's a valve stuck or the tappet is way too tight or there's a bent valve. Do a compression test if you can.

Couple of pointers if you don't object.

You'll find Honda fitted screws that are in fact too short for the drilling, the carb tops are a perfect example. Most of the thread is left unused and corrosion of that thread left unused mean if you attempt to fit a longer screw if starts to grab and then strip away the thread. Clean the threads with a tap, measure how much thread is left unused and fit a longer screw, that why a lot of them strip out, they are only really gripping on a few threads. IIRC, the top screws are 16mm and you need 20mm, the float bowl screws are the same, look at the pic and you'll see the screws don't reach the top of the thread, the pressure of the spring washer tends to strip these threads out as only a few are getting used. If in doubt, fit longer screws and trim to suit the position. Don't have threads of the screw exposed as they corrode and when you try and remove them it can strip out the threads as it passes down them. Go for a flush finish.
No objection Ken,
Learnt a long time ago about Hondas plasticine screws, so all my screws bolts etc are stainless steel replacements, usually but not always hexagon headed cap screws. Again from experience I always use a tap to clean up the threads so I don’t get caught out with stripped threads..
Just got my BZP kit from Gateros so all the rusty bits you did see will be brought back to original look, a new venture for me but I enjoy doing something that poses a challenge.😀👍
