Honda-SOHC

Thanks for the reply!
I just thought the engine was hondarattling alot without using the screwdriver, compared to when i turned the bolt counterclockwise all the way.

Has anyone tried the turn of the bolt, and found that the better way?

Thinking of welding a bolt on the end, trusting that the new oring to the cylinder head will hold the oil back and not need changing for a very long time.

And now i´m back to let you know i can really shake em down.

Thanks for the warm welcome, and astonishing response. Getting back to the Honda-project for a while now. My aim has been a longdistance (4000km) trip in the end of summer, but that´s really in the grey now, as i´m growing to the needs of the bike.

I Did:
- tank
- points
- timing
- chain tension
- valves sounds ok, so i left them as is

Now cleaning carbs, which didn´t look too bad, except thin white deposits on the two leftside carbs. One needle had a bad screw and i tried to bore it out but didn´t succeed, so now i´m looking for a single needle and throttle slide, if anyone near Copenhagen has such a thing I´d be happy to pick it up very soon. I think I´m keeping the airfilter for now, as an airbox is hard to get by.

Oilpressure-light, which comes on gradually as the bike heats up.
I´ve been carefully listening to the engine, and the sound changes of course when it gets it´s heat on, but that I figure is normal. No bad sounds, other than when it gets really hot from low speed city driving, it stumbles and using the kickstarter feels heavier.
I ear-synched the carbs, and it runs alot better, almost no stumbling when hot. Can´t remember if the heavier kickstarter remained or not.

As for leaks
Topend looks moist most of the time, drips from back of block once every 5-10 minutes when hot. Filled it up with oil 400km ago, and i can hardly tell its changed. Engine bolts are a bit rusty, so there is rust trails on the enginecovers from the top and down. Suspecting leaking carb here, as oil tends to a gasoline smell again, so i´ll change the oil again after the carbs are back on hopefully without a leak. Using 10w40. While changing the oil I´m fitting new gaskets to sidecovers of engineblock.
Checked for airleaks with both starterspray and a small gas blow torch. None.

Plugs (fairly new)
Cleaned and checked gap; and again black sooted after run, which points to a rich running, but it should be running lean as i haven´t rejetted yet. Needles where set to second highest which would make it even leaner. Will try to resitrict the filters as soon as the carb is back on and synched. So, can the black plugs point to oil burning? Bike is said to have 45000km on it, is it time for a top end service? Guess i´m going to do a compression test to see what condition the pistonrings are in.

Exhaust
Has been white at one or two occasions. Clean when idle, black when revving.

Hey people, greetings called from fresh forum member

Many thanks for all the exciting readings, that helped make me go for it. Hereafter; my first machine on two wheels bigger than 50cc:
[ Guests cannot view attachments ]

I´m turning to this incredible forum for some help on the diagnostics side, because i´m pretty fresh on SOHCs.

Has:
- paint job
- custom grips, taillight, speedo from wrenchmonkey
- Marshall Deeptone exhaust
- cheap podfilters, which it got without being carbsynced and hasn't been running much since
- tendency to overheat
- strange sounds (will post video)
- some oil leaks
- a good life coming

Needs, in suggestive order project starts at:
- gas tank clean
- inline gas filter
- timing
- valve adjust
- carb clean/rebuild
- carb sync
- possible cosmetics at some point

I´ll keep you posted along the way incase there are interventions or a good tip you want to share.
First of, later tonight, will be a video of the machine running. If you have any thoughts, feel free to share!

Cheers, good folk
