Is there someone in the forum that offers this service?
Do you have recommendations?

Well, yes there is.

With regards to no spark: clean the points and then follow the procedures. Checking plug caps, put the multimeter in resistance mode and set it to 20k. Caps should be around 5k. (Don't worry if they show 4000 or 6000, that's just down to the inaccuracy of cheap multimeters, as long as it shows some resistance, you're most likely fine.)

'77 750 shouldn't have a clutch or neutral switch cut-out switch.

Be aware that the exhaust, if polished up, might be quite sought after. If reasonably rust-free as only the early versions are available as replicas.

Stock resistance on the 1977 plug caps is 10k ohms.  They left very little room from being good to being burned out.  5K is what the NGK OEM style replacements should be.  Also, 1977 model does have a neutral safety switch and a clutch safety switch.

Hey guys!

"neutral safety switch and a clutch safety switch"-->does that mean that the bike won´t have spark if started in 1st or any other gear?Irk could you elaborate?

Nanno, the exhaust (OEM Honda,we have 2 sets of them) is in amazing shape,it will however get a rechrome,since the back ends are corroded and need a repair.(see pic).

The first task will be getting the bike to start and run a few strokes.
New intake rubbers (I hope I will get the carbs out of the hardened old ones,heatgun will help),cleaning the carbs and points,probably new plug caps,plugs and plug wires and fresh gas,lets see what happens :-)

Check the sidestand and the clutch lever. If there's (electrical) cables, you actually have a cutout switch. With the bike obviously being ex-Austrian-police-spec, I doubt there is. Normally such would prevent the starter from working and not the ignition.

I don’t know the nuances of a police spec 7fitty, but you normally need to have the bike in neutral with the clutch engaged to get the starter to turn as der_ nanno said. You still get power to the coils, so that can be checked with a meter. I swapped out for a different solenoid to bypass my safety switches, but you can also install a jumper. I’m not sure how the police version would’ve done it.

Engaged clutch? Wondered why mine just spit gas out and didn’t turn over. Didn’t know that was an issue!

My floats were stuck and couldn’t get them and a simple “clutch pull” hopefully will be nice. Thanks.

ATTENTION ATTENTION ATTENTION  8) 8) 8)

Reopening the thread...the projekt is in full swing.The bike already got transfered into my basement and the first works started on the dirty old girl   ;D ;D ;D
Its a former police bike so I will be swearing a bit while I do this project in order to de baptise the bike...no good police stories in Austria.

The first stop will be making the bike run.The carbs are now off for cleaning.Checking for spark and checking the electrical system is next.
Any Advise is like and needed for this looooong run..I´m doing this beside my day job so go easy on me  :D

A few pics.

First up the carburetors... Starting disassembling and sorting the parts.
I ordered rebuild kits. The carb is being disassembled and ultrasonically cleaned.

Carbs are dissassembled and now the search for the O Rings start.
The Keyster rebuild kit have 4 O rings plus the big O Ring for the float bowl.
I located a few already.Where do the the other ones go?

EDIT: Looks like 2 Orings go where the brass pipes connect th 4 carbs....Since I´m not planning on splitting the carbs these will stay.

The carbs now get soaked to get the most crud of then they will be ultasonically cleaned.
If you guys have any special advice on what to look out for It would be very helpful.

The first aim is to start the bike but not without changing out the old oil and oil filter.

And, if you have a leak on one of the cross-over tubes, you get to pull the rack and separate the carbs to fix it. Might be best to do all of that now.
