Hi all, long time lurker, first time registered user.
I have had my NSX now for almost 15 years, and have been keeping the old girl original and updating the usual capacitor issue prone components during that time. Hopefully the last is the head unit now, and Ive found a member here who can help with that.
Ive had problems with receiving emails and direct messaging. I can find a few references to this in the help, but even though Ive registered my acct via the email link, no joy.
A couple of pics in the meantime. Its unmodified so might be a bit ho-hum for some, but I like her fine :)

Very shiny red / black with original fat 5s that look pristine. Gotta love that! It looks like it has daylight running lights or are those fog lights?

You have only done 4 posts. There used to be a post count that you had to hit before private messaging was enabled. It was to try and control bots and spammers. The count used to be 10. Try responding to this thread a few times to get your count up and see if the PM gets enabled. If you have problems getting notifications I believe there is a separate setting in your 'settings'; but, it has literally been 10 years since I looked at that stuff.

Hi Old Guy, thanks for the reply. Ill do a couple of replies to your post to get my count up ;)
Those are fog lights on the front. Yes Im lucky the whole car is quite clean. It hasnt done a lot of miles and it hasnt been run much in the last 10 years. If I told you the mileage since the last service, you would laugh!

Hi again, thanks for clarifying the post count. I did try searching the FAQ's and didnt find any information or any Sticky posts for new users unfortunately which may help future subscribers. Maybe its a situation the site admins could review and rectify to assist new users. Its certainly frustrating when all Im trying to do is contact a member to have him fix a capacitor related problem, and I cant PM him for his details and he cant email me his details :) Sorry for the rant.

Thanks Docjohn, I like to keep things original if possible (I restore the older Honda motorcycles) and just appreciate things as they were. Ive even got a set of the original Yoko A022 tyres (tires) for the old girl if I ever decide to show her ;)

That looks like a very early CB750 because I think I spot a cap for the remote oil tank on the dry sump system. As I recall, Honda switched to wet sump some time around '73 - '75. Is the exhaust system original? In our cool climate the 4 into 4 exhaust system took a while to heat up and they would typically rust out at the base of the muffler in about 2 - 3 years if you did a lot of short trips.

Hi Old Guy, yes its an early CB750. First of the series 69/70 shape that I restored prior to buying the NSX way back. So its a pic of the first Honda Superbike and Supercar together. The exhaust was new when I installed it, but NLA now from Honda. New sets are prohibitively expensive now if you can find them. But yes, the originals usually rusted out or went to the scrap yard, replaced by aftermarket performance exhausts. The SOHC's went until 78, then replaced with a twin cam 750, which I think was still dry sump.

Sorry Old Guy, I posted a response with photos earlier in the week and it looks like it went to a moderator for approval and its not been done. I guess the new guys get (unnecessarily?) put through their paces here.

All the SOHC engines had dry sump 69-78 and possibly the DOHC soon thereafter. I had a mid 80's Honda GB500TT at one point using an XR500 engine which also used a dry sump. They're quite common.

The exhaust rotting out, or simply thrown out in lieu of aftermarket 4 into 1's was common in the day. The ones on this bike were new Honda pipes when you could still buy them about 10-15 years ago. Scarce and expensive now if you can find them, otherwise a CB750 restoration business in Japan has reproduced them very well and the majority of restorations will use reproduction pipes.

Your CB750 looks to be in time warp condition just like your NSX. How many miles / km?

In North America Honda introduced its first F version of the 750 in 1975 It had a mungo huge 4:1 exhaust collector on the right side which would hit the ground if you got into a corner too hot, a rear brake disc, rear-set pegs depending on the market and had switched to a wet sump design. You can tell the wet sump design in the pictures because the oil tank with that big fat flex line out the bottom has disappeared from the right side cover. I also had a later 1980 DOHC 750F which was a wet sump design. The wet sump design had an unfortunate design feature in that the oil ran hotter. On the DOHC engine the clutch would become very grabby once the oil got hot which made for miserable around town driving. Fixed that by retrofitting an oil cooler.

I posted a few more pics of the CB with my NSX but just waiting for them to be approved, however it was a complete restoration so basically as new. It was fresh paint, fresh chrome and complete engine rebuild. It was my first full restoration on a bike so it was a nice bike when done. It was sold a few years ago now, to fund other builds. There are a few still in nice original condition. These are now more appreciated by collectors as there were quite a few production changes in the early bikes which is what makes them much more valuable than the later models (i.e. the original early bikes with the early superseded parts command a premium).

The 75-78 F1, F2 and F3's still used the basic SOHC engines albeit with a few performance mods, and production changes compared to the K models. The F2/F3 black engines especially. They were still dry sump though - the oil tank shape changed with the sidecovers but if you look carefully at pics, the oil lines are still there. All models do benefit from an oil cooler too - especially once the engines have had a few performance mods.

Live and learn.

I never had a ride on a later K model; but, you motivated me to look at some photos and the oil tank filler is still clearly visible under the right side cover. I did test ride the 1975 750 F and since the oil tank was no longer visible just assumed that the engine had been switched to a wet sump design. However, a close look at some photos of the 1975 CB 750 F does show the oil line closely tucked in there so the oil tank must be in there - some place. I purchased the CB 550F instead because it was lighter and had a 2" shorter wheel base which made for a quicker handling bike. It had the same style oversized 4:1 exhaust collector which would hit the ground and lift the rear wheel if you got into a corner too hot - sphincter factor of about 9.5!

Love your original Oz delivered mate. I have been a long time NSX lover but for some reason never got one until the prices shot up. As luck would have it no Oz delivered cars turned up whilst I was looking to buy and I ended up with a JDM car. Of course just months after I purchased my car an Oz.delovered turned up... And for cheaper than I bought my JDM. Ah well scuh is life.

Welcome to NSX Prime! You should post a thread here showing off your new JDM NSX- we'd all love to see it!

It's really an anti-spam/scam strategy. When spammers make it through the filter and register, they will blast out thousands of spam PMs to the entire member list of the forum. By preventing them from doing that for the first 5 posts, most of the time they give up and move on. If you need to send a PM, reach out to a site admin like me or Lud and we can manually take you out of that group. Obviously, I know you're not a spammer LOL so I'd be happy to do it. Though, it now looks like you're past the limit so you should be fine.
