Hi Dash

No! the relevant paperwork / certificate of restriction was done by a firm in Daventry and tested by a firm in Bexhill on Sea and must be a proper test job as all power outs are recorded on the certificate and is reduced to a Max speed of 98mph 156kph if it goes that fast I will probably c--p myself.

But I will still have a look for the nature of said restriction

regards

Mikenic
PS further reading of the certificate lists

Restriction  Device
a    Blade
b    Device code  02-NC27-K25
c    Device Details and Dim's
Outer Dia =   35mm
Inner Dia   1= 17.5mm
Inner Dia   2= 3mm
 All alien to me   
                                                         
                                                                                           


Then the whole 25kw thing is a coincidence I guess.

The bit about the restriction device speaks of diameters... That would suggest a restriction in the carbareteurs like Morti said. At least, I reckon it does. Tongue

Thanks Dash

I will check that out when it warms up in the garage! just what was the purpose of restricting the bike was it a licence thing?

mikenic


Well, since you mentioned 25kw...

Does it happen to be / have been a Dutch registered bike? In the Netherlands we used to have a restricted motorcycle license that allowed only 25KW output on bikes. So Maybe that's where it's from?

Sometimes bikes get restricted by limiting the amount of throttle you can give by mechanically 'blocking' the throttlehandle from twisting any further. It's quick and easy to check. Usually there s a small bolt in the throttlehandle somewhere that functions like a stopper when a bike is restricted in this fashion.

Respect man. Grin

Good job fixing it. We need more cb1s on the road

unfortunately...it's all about "perception" and not "performance".
here, in the U.S.of A......idiots rule. Folks who believe bigger is better rule what bikes Japan produces. if you aren't riding a 1000+cc superbike, yer a puss, hence "perception" not "performance".
Only in Southern Cali have I had the pleasure of experiencing what its like to ride a small bike fast. A CB1 and I'm grateful for being able to have experienced this sensation.
But...the entire US is not SoCal is it. Folks here really appreciate small, revy, well-built engines and they love to rip em thru the canyons.

Maybe Honda Motors will wake up....but I'm afraid that for now, your dream of the modern CB1 will just have to remain a dream.
they're trying to make it as narrow as mechanically possible, yet have that neat cranck-config that provides better torque.
Whilst all the while not wanting to make yet another 4-cylinder CBR type bike.
I'd prefer for Honda to make another CB1, now they'd have my attention if they did that.


Imagine a CB-1 (with of course the CBR 400RR engine) in a modern day lightweight frame with USD suspension and massive floating brake discs  Roll Eyes

*drool*

Same over here. Not just 'Merica. Everyone here is going on about how much BHP you need to have. How big your engine is etc etc etc.

Which is fairly stupid, because a 400 cc is perfect (and so much better than a big bike) in so many everyday scenarios. But your CC-Peen isn't big enough with just 400cc's, apperantly.

It does make the encounters with people who appriciate 400's all the better though. At least in my experience. Back when I rode KTM supermotos I got a lot of attention (not the reason I rode KTM, mind you) from the sidewalks. But only from young stuff that could only ride a moped, and those 'thug life' hooligan wannabe poser simpletons. Those guys don't give my CB-1 a second glance (so they wont want to steal it. yay!) however. But now, I have older people / riders approaching me to have a chat about the Smurf. Who are without exception awesome people btw.

Mate who owns a Ducati 1098 (note that I write 'owns' and not 'rides' cuz the PoS won't work properly being a Ducati) who looks down on older, cheaper bikes, said he though my CB-1 was a single cilinder bike.

I nearly strangled him to death with a fuelhose.

Japanenglish is so funny. I once worked for a Japanese company and their technical manuals had us in stitches with phrases like 'Concentrate your mind or death might be quickly'.


That one is glorious. Hahahahaha Cheesy Cheesy

This is soooo obvious. Roll Eyes

I never explode the exhaust box near horses.

I do entangle festive dogs in the spokes though. I really should stop that, having read this.

Thanks for the advice. Got a multimeter now and commencing the checks on all wiring. Nothings worked up till now and it's made ever more difficult that the problem is sporadic.

Those issues are the worst. You'd almost prefer the crankshaft smashing through the cilinderwalls. At least then you know what the issue is. Electric gremlins are the worst.

Good luck man.

Thanks guys. Gonna take your tips to heart when I get to disassambling the lot.
11  General Category / Tech Corner / Re: Front seals keep leaking on: October 03, 2017, 05:06:57 AM
Have you replaced the bushes yet? As they wear, you can get more play in the suspension which will put undue stress on the seals.

Also be sure you're not over filling the oil as this will stress the seals.

I dont think the bushes have ever been replaced.

Also, overfilling isnt an issue I daresay. Always kept to the prescribed amounts.
12  General Category / Tech Corner / Front seals keep leaking on: October 03, 2017, 03:08:07 AM
Im having issues with the seals in my front suspension: they start leaking every time. Ive already changed them twice now to no avail. I then replaced the front fork uppers with new ones thinking that the small dents / scratches on the uppers may have been the cause of the leakage. Apperantly they were not: with new uppers the fork seals still keep leaking.

Im kind of at a loss here. The uppers are nice and smooth, there s no denting or whatever in the suspension travel. The seals are installed properly. Could it be the lowers perhaps? Huh

Photobucket dropped the ball hard...

Glad I still use the crappy upload service my Motorstek provides Wink

This is a good tip for ex-photobucket users though Grin
14  General Category / Photo Gallery / Re: Dash and CeeBee went to Circuit Zandvoort on: September 01, 2017, 10:19:18 AM
Looks like a fun day out - I did warn you that doing track days is quite addictive

Next one, 30th august, has already been booked  Cheesy

And completely ruined due to rain. Didnt even bother to go to the track. Embarrassed

Next attempt: 18 septembre Grin
15  General Category / Tech Corner / Re: Rain tyres for standard Rims on: September 01, 2017, 10:06:02 AM
The guys who race the 300 Ninjas with our club (BEMSEE) use Diablo Rosso's in the dry and Pirelli wets which are an odd size 100/80/17 front & 125/70/17 rear (it's normal for wets to be a different size to dry tyres as you want to spread the tyre for a better contact patch - or something like that was explained to me  Huh. The Ninja wheels are the same width as those on the CB-1

This is all getting very serious Dash, having 2 sets wheels, you'll be taking up racing next  Cheesy

Pirelli wets eh? Thats an excellent suggestion. So there are rain tyres that fit the CB rims. Good news indeed!

I happen to have an extra set of rims laying about. Wink

And It s not like Im trying to become a moto GP rider. Its just that I was really bummed out at not being able to do a trackday due to rain... Stupid climate we have here.
Ive one chance left this season but Its gonna be tricky getting a spot I fear. depening on the forecast, Im gonna take a look at these pirelli wets.

Thanks for the info!

Also, diablo Rosso's also fit the CB1 rims then? Ive heard good things about those. Might be an alternative to the S20 Evo's Im running now, by means of an experiment.
