Your SC21 is 30-32 years old and run over 300,000km. Still using factory set piston seal is far beyond expectation.
How about your brake master cylinder piston seal?

Aprilia Rotax V990 engine has hydraulic clutch. And as I said, many people have problems with their clutch.
Newer Aprilia V4 engine went back to wire clutch. Probably Aprilia also recognized hydraulic clutch problems.

At Honda, basically all over 800cc engines have hydraulic clutch. But I did not hear such problems.

I have a replacement plan for only master. Futura and RSV1000 have 12mm at master and 28mm at slave.
Nissin has 1/2 inch,14mm and 5/8 inch for master. I will hunt 1/2inch used one.

Brembo slave cylinder has different mounting bolt positions. Therefore,replacing it with Nissin is difficult.

Usual Brembo slave cylinder is like this.

And I think replacing fluid in Brembo slave cylinder by ordinary bleeding method is difficult.
Because bleeder valve and fluid intake are sitting on same bleeder plug. And the cylinder is dead end.

I checked shape of SC21 slave cylinder.  Bleeder valve and fluid intake have each own position.

Even today, Brembo slave cylinder shape is not changed. But I like Nissin shape.

By the way, how many times did you change clutch slave cylinder piston seal of sc21 for 30 years? > robvangulik

 What thing triggered you decide to replace slave piston seal?

My latest vehicle, Aprilia Futura has hydraulic clutch. For me, it is first hydraulic clutch motorcycle. But many people have clutch problems with Aprilia/Brembo clutch. Like leaky slave cylinder, too heavy clutch lever, and Brembo seal supply problems.(Brembo did not sell rebuild kit via Aprilia channel.)

 My Futura has leaky piston seal problem at both cylinders. Currently it is working. But I have uneasy feeling.
 I am considering to replace Brembo master cylinder with Nissin. Because availability of Nissin is far much better than Brembo.

The reasons are revealed in different thread.

Scotty Kilmer also said 'Why car guys don't buy new cars' at following video.

If I win some lottery, but I will not buy new motorcycle.

Because it is expensive and lacking of irresistible charm. At this point, I am satisfied with current fleet.
NX650, CBR750 and Futura. winkywinky

Also I don't have huge space, not like you. Three is enough.

In fact, old regular plug has no problem. Just I checked all ignition related parts including the plug.
But I could not find root cause. After assembled the parts, the plug was fired up.
At that time, I had new Denso Iridium as spare. So I decided to replace spark plug. Now, old NGK plug resides in NX650 toolbox.

 Probably the root cause is poor connection of CDI unit.

Several years ago, I experienced similar result at NX650. At that time, NGK Iridium was not so good. I replaced it with regular NGK plug.

Denso is late comer for spark plug market. When they entered the market, NGK's reputation was rock solid.
So they focused Iridium plug.

Now, Denso has higher reputation than NGK at least Iridium spark plugs in Japan.

A couple of days ago, my NX650 had iginition problem. I checked coil,CDI, plug cap then replaced spark plug with new Denso Iridium plug. At this point, it looks like fine.

All Technical Issues / Spark plug type
« on: November 03, 2019, 01:24:04 AM »
I found strange descriptions at Denso and NGK site.

At Denso.
CBR750F                                           X24ES-U           IX24
CBR750 SuperAero                          X24EP-U9         IX24B

At NGK
CBR750F                                            DPR8EA-9        DPR8EIX-9
CBR750 SuperAero                           DP8EA-9           DPR8EIX-9

 Left plug type is regular. Right plug type is premium Iridium.

 We know 1988 CBR750 dropped 'SuperAero' naming due to unknown reason. But also know Honda called it   CBR750F no matter how production year is.

 As far as I know, there is no difference between 1987 model and 1988 model regarding ignition system.
 It looks like original CBR750FH has non register type plug. Then Honda switched register type plug at FJ.

I think previous my description is wrong.
But that gauge has SC21 speed meter and RC27 tacho meter.
The restrictor resides in speed meter section.

What I can tell you is as follows.

Yours is 1988 year model, FJ. Because the front brake rotor is floating and the rear direction indicator is separate type.
FJ is much rare than 1987 model,FH. I guess total production number of FJ is less than 2500.

There are four version parts lists and two version service manuals.
The last version parts list and the last version service manual have FJ specific description.

Obviously front upper cowl has different color. The gauge has SC21's 180MPH speed meter. But the tacho has Japanese speed warning lump which means Japanese 180km/H speed restrictor inside.
Yours does not have a belly cowl and has aftermarket silencer.

For battery protection, you need intelligent battery charger or tender.
Blute-force charger may dry up your battery.

And checking Regulator/Rectifier healthiness is necessary. OE Shindengen regulator/rectifier is good. But it is 31 years old. It may lose its capability gradually.

There are several petrol tap repair kits in ebay.

Please search 'petrol tap repair kit Honda' at ebay.
Of course, there is no kits for CBR750 because CBR750 is JDM.

But all petrol tap has same function. The key point is membrane sheet size.
First of all, you have to decompose your petrol tap and find out which part is broken. Then check compatibility.
As usual, vehicle vendor never tell you parts compatibility.

Original CBR750F does not have a fuel pump. However, CBR1000F(SC21,SC24 adn SC31) has a fuel pump.

According to my understandings, CBR750F fuel supply system is as follows.

                                                                                                                             -----Carb #1
Fuel tank -> fuel strainer -> fuel cock -> fuel tap ---->  T branch #1    ---- Carb #2
                                                                                          ----->  T branch #2    -----Carb #3
                                                                                                                              -----Carb  #4

Several people reported their fuel tap has problems. There is another thread about fuel tap in this forum.

It is coincidence. But I have never been owner of Kawasaki.

Questions and remarks about the Site or Forum / another isalive.nl site?
« on: August 24, 2019, 03:26:56 AM »
As you know, the site was down for just couple of days. then i tried other sites. like

blackbird.isalive.nl
fireblade.isalive.nl
dominator.isalive.nl
honda.isalive.nl
fzr.isalive.nl
rsv.isalive.nl
gsx.isalive.nl
ducati.isalive.nl
futura.isalive.nl
vfr.isalive.nl

 All displayed server config 404 error page.
 However, www.isalive.nl has a page. You can watch it for yourself. Probably this indicated domain owner's taste.

 And I checked hurricane.nl and hurricane.com.
 And I found out why crusher has isalive.nl. You can check this for yourself.
 Whois info of isalive.nl is masked as usual.

Just FYI
