Topic: 750F thread?

[RSchaefer]

Relative to the rubber spigots - I have an F0, but have noted elsewhere that the 77/78F spigots are slightly shorter then everything else.  I think the 75/76F's are the same as most of the K bikes.  You probably already knew this, but just in case the 77/78F spigots are unique!

Cant believe it took me so long to find this thread.
This is my 77F that i bought this past summer.  I had an 81 650C before, but i needed something bigger because i am 6'3" and i love the looks of the F model.  Plus my father in law has one in parts that i have access to for free...so that helps.  When i got it it had a big ugly seat on it, was missing missing the rear fender, and had a broken left side cover.  The carbs also had pods and needed tuned properly.  A PO had added a chrome swing arm, rear sprocket, and gauge buckets, aslo some lower bars.  An original seat and fender off feebay, an LPM side cover, and a stock airbox with some help from my father in law got it to its current state.  It still needs a new stator cover.  My father in law has one, i just need to get it painted and put it on.  At the moment i have the tank off because it developed a little rust and was starting to weep fuel.  I am lining it and hope to get it back together by this weekend, as i am getting married and would like to get a pic with it

The are shorter and the carb side is a larger diameter too.

Anyone know where I can get hold of replacement tacho or speedo dials for F1 (they are a green colour...)? Particularly the rev counter...? Also wondering about touching up the red/orange paint on the ones I've got - any ideas of what to use, or am I just going to make a complete hash of it??

I'm assuming that by green color you are referring to the light green color as found on our 1976 F1 in the states vs the dark green color found on our 75 F/F0 in the states which was made only from from Jan 1 to ~ Apr 7, 1975?? I picked up a dark green faced tach for my 75 F0 from David Silver Spares a few years back at a very decent price considering he had 5 or 6 with only 15,063 manufactured and it wasn't a European bike. Being concerned about the darker green color I very carefully verified the correct part number especially considering you blokes in Europe did not get the 3+ month version of the 75 F model and your F model had a different (early K model) front fender and turn signals. Not to be confused either with what some guys think is a blue face but actually is faded dark green. Anyway..... no, I haven't seen anyone producing the later faces with the 8500 redline.

Yes - my colour is indeed the "light green"... have been hunting around and the CMSNL website shows part 37250-392-771 as the part for my bike (cb750f1 - light green dial) for serial numbers up to 1038906 - out of stock, but for serial numbers from 1038907 show part 37250-405-771 (superseding part 37250405009) as in stock and indeed if I direct input this into David Silver site it is shown as in stock... anyone have any ideas if there are any major differences between these? I do notice that they have different back plates, but this just seems to be to take a different size grommet on the wire...??

Theriddler..
There is a brand new tach on EBay for sale.. Last week one sold for just over $100.

yes saw that...if I hadn't been in the middle of family xmas "discussions" would have had a go.... Thanks for heads up on 2nd one! Will see what happens. Have spent a wee bit getting exhaust up to as new conditon tho'!

I've now got my new exhaust...! A while ago I was struggling to work out what the baffles were in the standard silencer I had (rotted out...), so thought I'd psot these pics in case anyone was interested...?

[theriddler]

New CB750F1 1976 exhaust photos...
The other siencer is the one I have with rotted out baffle(s)...
If any one wants any info before I put it on bike let me know...?

[Jerry Rxman Griffin aka MuthaF'er]

Nice catch on an unobtainable muffler! Where did you find that, what was the cost and would there be any others available?

I use Motogrid.com for my parts cross referencing and ID'ing. From my experience the CMSNL site is by far the most extensive listing and it has the only complete breakdown of ALL models by country. GREAT site but users need to understand that.

http://www.motogrid.com/pages/OemParts?aribrand=HOM

From there, here are serial numbers for the US MODELS (which may also be on models from other countries but not necessarily so) for your part numbers so be careful when using just serial numbers as many/most people don't understand those small peculiarities to some of these parts for certain bikes. For the gauges the difference in the part numbers is the last 3 digits which determines the year and color.

"37250-392-771" = CB750F A (76) MOTORCYCLE, JPN, VIN# CB750F-2000003 TO CB750F-2022317 - In the US the 75 model serial number was CB750F-1xxxxx while the 76 was CB750F-2xxxx

"37250-405-771" = CB750K A (78) MOTORCYCLE, JPN, VIN# CB750-2800001

The 78 K is NOT the exact same face but it would probably work just fine however I know that you want the original stock face.

Thanks for the extra info ... I didn't think of checking K8 part no's! Yes I am trying to get the original... bit low on cash now after getting muffler... got it from ebay - a guy who has a fair ammount of "F" parts I believe - here in the UK. I also got the down pipes off him too. Silencer cost about £380 with postage. Fixed down pipes with collector box cost around £60 with postage (no sign of usage i.e. exhaust carbon etc... onlt thing wrong a couple of small "handling dents on bottom of collector box area...) . All in all an excellent find!

If you already have the part number you can cross reference it to other bikes on the Motogrid site or you can look up the part number then cross reference. Just be careful on the superceded numbers. I have an original 75/76 F Honda parts catalogue if you ever need the original number.

[Radam]

Jerry, do you know where the link to the engine numbers is to find out what year an engine is? I've searched on here, but couldn't find it. Also, sorry for posting the sale parts on here. I deleted the post and made a new one in the proper area. Thanks.

[Jerry Rxman Griffin aka MuthaF'er]

CB750F = CB750E-"2500001 to subsequent" (see the 76 beginning number)
CB750F1 = CB750E-"25015094 to subsequent" (is around # 250055xxx)

http://www.hondachopper.com/engine/engine_timeline/timeline.html

However do not believe that the 750 F engine had a F in the serial number, just the frames. In all likelihood the engines were all E's too.

Yes... that ties up with my F1 "F" in frame no. and "E" in engine no...

Thanks. I bookmarked it this time so I won't have to ask again.

Heres pictures of exhuast fitted and gauges showing very dull tacho...

[theriddler]

last try...

[HonderCB]

except for the redline area i'd say that tach looks pretty nice.  definately has more color than mine.  I call it patina lol

[Jerry Rxman Griffin aka MuthaF'er]

Everything I saw looked really nice. Even the master cylinders don't look like they have faded much.

[cben750f0]

@ weedo2 thanx M8, the pipesa are made by a company here in OZ called Tranzac, they have bigger bore headers, and a nice sounding muffler that the baffle can be taken out of. I have the NOS full F exhaust system hangin in the shed. might go back on the bike when i return it to original..... maybe.lol

peace

Thanks - I also have a parts catalogue - falling aprt now because I'm constantly running through it. Actually thats quite good, just hope I don't lose pages!!!

Hi - has anybody tried:
http://www.clocksndials.co.uk/welcome_text.htm
for gauge dials £33 for a set... I have a spare F1 tacho which I tought I would "recondition"... even try overhauling the mechanism as well... might go hunting for advice/ tips. Just thought I'd post this here as I'm specifically lookng at the F1. The dials on this site show an F1 coupled together with a K7... dials look OK for an F1...?

[kap384@telus.net]

my '78 CB750F3
picked it up in June.  My first street bike and SOHC4

Awesome first SOHC!  Good choice with an 'F'

[theriddler]

A few photos of bike with new exhaust...

[750bobberrat]

heres my 77 cb750 with alot of changes

[Jerry Rxman Griffin aka MuthaF'er]

Nice job. I do recognize the engine anyway
