Buying and Selling / Re: What to do

« on: June 26, 2021, 23:41:26 PM »

If you find a decent buyer and deal, selling is better.

Too many motorcycles may cause several unwanted problems. Parking space, insurance cost, too many wrench works and so on.

I think some Briton in this forum was searching CBR750....

In English. Please use deepl.com for translation.

There are five RC27 engine auction items in Yahoo Japan.


https://page.auctions.yahoo.co.jp/jp/auction/m382179859
https://page.auctions.yahoo.co.jp/jp/auction/w466904667
https://page.auctions.yahoo.co.jp/jp/auction/l550188652
https://page.auctions.yahoo.co.jp/jp/auction/e372777254
https://page.auctions.yahoo.co.jp/jp/auction/p790749111

Most of sellers don't want to export the item. Because it may need time consuming paper works.

However, if you really badly need RC27 engine and are willing to pay big money, I can ask the seller. Because it is difficult to find a domestic buyer for them.

For more detail about the listing, please use deepl or google translation.

All Technical Issues / Re: Does anyone know turn signal indicator's connection at RC27?

« on: February 18, 2021, 13:06:37 PM »

More than four years ago,I replaced all lights in dashboard with LEDs except for speed warning. I don't have any problem at dashboard.

I did not replace turn signal lights at front and rear. My RC27 still has OE old plain bulbs.

I have a plan to replace turn signal lights with LEDs. Not lights in the dashboards.

Usually turn signal light has ba15s type socket. Socket has asynmetric pole layout. You can not try 2way polarity test, like T10 or T5 socket.

At NX650, I found Honda's original wire connection is reverse. Therefore, I had to modify cable connection for ba15s socket.

What I am asking is, Does anyone know RC27 ba15s socket wire connection is normal or reverse? I think bottom= + and side = - is normal config.

Please see attached image for ba15s.

As I wrote at prior post, I replaced all dashboard lights except for speed warning light. Because speed warning light needs testing at 95km/H for knowing its polarity.  But all other lights in dashboard were replaced with LEDs. I don't have any problem. Just coloring difference.

What I am asking is, turn signal lights at front and rear, not indicators in dashboard.

Regarding dashboard back lights, I already replaced those with LEDs. I did not need diodes.
But I did not replace speed warning indicator. Because all socket type of dashboard is T10 or T5. So we need to test polarity.

However, socket type of the turn signal indicators is S10. The socket itself has polarity.
I have new IC type compatible flasher relay for Mituba FR-3303. So I don't need extra components other than replacement LEDs.

Is that correct?

Why do we need diodes?

When I tried to replace ordinary lamp with LED at Honda NX650, it did not work with IC flasher relay.
Because NX650 turn signal indicator socket has reverse connection. It means side is + and bottom is -.

Ordinary light does not matter it. But LED has polarity. It matters.

That's nice. You used word 'restore'. So I assume the Hurricane is not running condition.

As usual not running MC, it may need OH for carburetors and calipers. Hurricane unique weak point is plastic shells. It may have broken parts.
Other problem is, availability of parts. Because relatively small production number. Probably less than 6K.

Honda parts # has XXXXX-YYY-ZZZZ format.

YYY is model proprietary no. If YYY is MM4, it is CBR750 unique parts. Most difficult to find such parts.

If your customer has deep pocket, you can find complete CBR750 in Japanese used MC market at less then $1500. it does not include S&H.

However, Japan and NZ are relatively short distance. Probably shipping may be less than $2000.

Questions and remarks about the Site or Forum / We need sub-forum for posting test article

« on: January 26, 2021, 02:17:08 AM »

The latest incident is, dysfunction of posting and sending PM. But viewing article,stat and member list has no problem.

Therefore, we need sub-forum for posting test article. But we have to expect spammers may use this sub-forum.

According to my memory, simplemachine forum has a config that automatic deleting articles in sub-forum.

Due to the pandemic, her season 3 ended at relatively few episodes. Because She was not able to enter Finland.

About week ago, season 4 started. It looks like her motorcycle sports series in Netherlands.

The control terminal connector sealed its coupling.
However, B&M teminals have just rubber covers. But it may be ok.

I think true problem exists inside. At off, resistance should be infinity ohm. At on, it should be zero.

At this point, I think cheap new Chinese parts is better than 32 years old genuine parts.

All Technical Issues / Starter relay

« on: October 17, 2020, 06:27:00 AM »

Recently I experienced starter relay problem at Futura. And I fixed it.

Then  I checked RC27's starter relay today.

At off, there is 5.5M ohm between B and M terminal.
At on, there is 1.7M ohm between B and M terminal.

I decided to dump this starter relay even RC27 did not have starting problem. I was not satisfied with sound of the starter.
I ordered cheap compatible parts to China. Because Futura has no problem and time is on my side

For the reference, I described about pin assigments of control terminal.

1 and 2 are NC
3 = 12V

 For testing, you need regulated DC supply.

Well, no matter how any song exists or not . Her interpretation about Ronin is wrong.

Like,
Naming Knight to her motorcycle and call her.
Naming Hooker to her motorcycle and call him.

Most of people don't do such thing because concept of knight and hooker are well known to western world.
But Ronin is not the case.

What does this banner mean? It is assigned to users without own banner.

According to my memory,most resemblance picture is a paint about woman's hip on the door of toilet room in U-Boat  by  German movie Das Boot.  But I think this  does have different meaning
