CBR150 motors

[jasonu]

Anyone out there know anything interesting about the CBR150 twin cam water cooled motor? What are they worth? Can they be made to make reliable power? Were they ever produced fuel injected like the smaller CBR125 motor? Can you get parts for them? Any for sale in NZ? Who is using them in a bucket racer? How do they compare to the FXR? Anyother comments smart or otherwise?
Cheers.

Man you are behind the times, see 2012 GP results to answer half the questions above.
Compared to an FXR well - shorter stroke, large valves, better port layout, fuel injected, water cooled need I go on. Theres a few kicking around in NZ, I've heard of them being picked up for as little as $1500, that said they are under $3000NZ brand new in India!

The 1012 CBR150 is fuel Injected and both the 1012 125 and 150 were brought out with longer swing arms and wider rims (Adrian who races buckets in Wgtn imported them for his CBR bucket).

I have gone down the path of turning the 125 (starting 3years ago) into a 150 mainly because of the fuel injection with some promising results. PM me if you want to know more.

[crazy man]

would like one myself but can't find a motor here in nz

Hi Jason I belive it would be a good starting point to get some more longer lasting power than an FXR. Being water cooled and all. Nick Cane or Alistar Hoogie said at one GP that his gearbox was playing up. That thought didnt sound good to me. I havnt seen one for a good price so have stuck to the old FXR.

[koba]

By far the best standard engine I have experience form a subjective riding test point of view.
Heaps of power over a long range and real meaty.

I was starting all over again I'd start with on of these engines.

The 125 is shit.

What he said. From stock they are really strong engine for sure. Not seen a super worked one yet but it won't be long I am sure. I thinks Nicks one had a good tickle up. But nothing crazy. Anyone know what they weigh in at?

[NOID]

The 125 is shit.

thats why i sold mine !!

[F5 Dave]

I'll have you're old engine thanks. Far better basis.

[jasonu]

Cheers for the replys team. I am looking at one near here and am hopeing to get it for cheap. I will post again if there is anything new to add.

Jasonso your going to sponser me it? cheers

[husaberg]

Its a Honda........... What else do you need to consider:facepalm:

[jasonu]

Arrived today with carb radiator and electrics.

[husaberg]

Arrived today with carb and electrics.

Will it fit in an NX4 .......................

[crazy man]

Arrived today with carb radiator and electrics.so what kind of money did it cost you over there

[jasonu]

Will it fit in an NX4 .......................

That is the plan.
Shorter front to back than the KE cases so will fit further back. It is quite a bit taller but hopefully the NX4 spars will be wide enough. If it won't fit then it will be put up for sale on a website near you (for more than the price stated below, still have to pay to get it to Noo Zulland)


so what kind of money did it cost you over there

$400USD delivered to my door.
They were never sold here. Some guy imported it from Thailand for a project that never happened and put it on ebay which is where I came along.

if this f-er fits in and the CRF250 do to with some case work. the 150 should slip in.

pop it in your hand luggage would ya........ lol

[jasonu]

That has already been seriously considered (and rejected)

So is that actually a CRF250 engine???

Ya wimp Boote used to bring a compete (Albeit stripped down) TZ750 on international flights he even used to ask strangers to carry other bits of it to avoid excess bagage charges.
I guess the US border Security might have been beefed up a bit since then:innocent:

i think it is a Bmw450 but not sure?,, my french is no good but bw is mentioned a lot.
if you go to the nova gearbox site in the uk you will see the changes they make to fit the 250 into the NX4
there are other threads about as well.

Excellent price, that's a steal!

It was a bit tight and water pipes would need changing, too much work for me !

NX4 spars are a fair bit wider than your NF4
Motor weighs 24.5kg. Anyone know what a FXR motor weighs???

FXR stock is 28kg.

[Yow Ling]

Just had my CBR on the dyno,
274908

might be the most conservative dyno in the country !! 14.28hp

Is that your home built dyno?

Standard CBR?

[koba]

Oh, now I read the test notes...

My info says they make around 19hp at the crank standard so your result is not far off the mark.

[crazy man]

My info says they make around 19hp at the crank standard so your result is not far off the mark.a stock fxr 150 on my old dyno jet years ago was 14.3 hp so what you have there wound be close. nice graft think l may have to get the program as you

I raced stock cbr 150's in 2006 and they were all around 15hp .
They all started to break when the cam timing was done - on the over rev of gearing down .

These days they get 22 hp very easily

If you read performance bikes in the 90's you should remember the Bugerman.
his software and home made "burgervan" dyno was all they ever used.
He gives his knowledge and software away freely because of becoming a paraplegic.
Same as his other stuff like the NO2.

[richban]

What does your bike weigh?

91 last weigh in. Should be able to get it around 87 with better exhaust and RS rear shock.

the download wont work on 64 bit systems, the other download is some sort of info pack, go to the products page and they want 3000 pounds for their system
maybe its not what it seems

Dynamometer Software


This dyno software download includes a full uninstall (from the Windows menu). It features full install as well as creating a program group, and icons for you. It is a self extracting zipped file and should be saved to a directory of your choice or better still, a floppy disk if you have a clean formatted 1.44 Mb one around. Just double click this saved file Dyno.exe to install. Needs MS Windows to run.

Requirements:

PC with 386+ Processor
VGA Colour Monitor
1.5MB Disk Space
Mouse
Any version of Windows - 3.1X up to Windows 98, will run on 2000, and XP as well but not as well.

This is one of two versions that you may download on this page. This one is bigger, so downloads more slowly but is more complete and easier to setup.

This software will take approx 6 to 10 minutes to download.

Just click on the icon below to get dyno software.

He has a question and answer section the download worked for me...........
yes he does offer another package but that is for all the other bits needed sensors etc and i guess better software........

[Sketchy_Racer]

That and you have to build the dyno to his specifications as the software wont let you adjust the inertial mass calculations. From what I read when we were looking at dyno software.

[RDjase]

How do you calibrate a dyno?

Get a medium size horse to run on it, and set that a 1Hp?

[Yow Ling]

just download the hp cal app and boosh its done

[Sketchy_Racer]

Close, but not quite,

We put a mountain bike on ours and adjusted it until I made one HP, so ours uses the "Sketchy" power measurement unit.

But seriously, from a cylindrical mass we can calculate its rotational inertia so we know how much "work" is done to accelerate the mass and then from the measured time it took to accelerate the mass we know how much energy was used. Using data acquisition units they plot timed points with a time stamp and RPM stamp at a given frequency (higher frequency = more accurate) Then we use that to make a torque curve and then from the we can convert this to HP by the classic torque x RPM = HP which is actually torque(Nm) x radians per second = Kw then the Kw is converted to HP because we all like to brag about HP levels rather than Kw which is the metric measurement.

More detailed info here http://wotid.com/dyno/content/view/16/35/

[Yow Ling]

All I had to do for my dyno was fill in a few boxes about diameter, width and material of the drum, it calculated the inertia 132 lb feet squared in my case, didnt require any brainpower from me

Brainpower is for geeks.

The CBR150 motor mostly fits. There will be some carb and radiator clearence issues but nothing too difficult. Aiming for 76kg with oil and water.

[husaberg]

You really should be ashamed of yourself:rolleyes:

It's bad enough that you are over in the US, making Cruise Missile's Stealth Bombers and so forth.... Now this

[kel]

I call BULLSHIT. Replace the wooden blocks with bungy cords and you might get close :lol:

only if no mates bike at 75KG is bullshit ,thats what he told mark his bike was,as i have had a RGV125 motor the same as a RG150 and they are 25kg the CBR150 is 24kg.

[jasonu]

NX4 RS125 weighs 71kg half wet. The CBR150 motor weighs nearly 6kg more than the RS 125 motor. Add it up, 76kg is not unrealistic.

[F5 Dave]

Thats pretty impressive. But bet it makes a crap noise.

Good luck at the GP.

motor No 3 RG50,hope to make mounts to fit all three motors,KERG100 CBR150 RG50,see which one is best

[F5 Dave]

Come play with the boyz!@

motor No 3 RG50,hope to make mounts to fit all three motors,KERG100 CBR150 RG50,see which one is best

this is how the CBR and KE100 motors will have to fly in this frame,have done drawings for top motor mounts on all 3 motors and will make set up mount from 3mm alloy next week when i get my new jig saw.making and fitting the pipe for the KE100 set up will be NO fun.

Slow progress. Is it next week yet? ??305364

[bucketracer]

How is the engine fitting going? Will you be using the CBR or RG50?

[jasonu]

RG50 first. It is the easiest to fit. 2nd will be the RGKE 100 motor. It is a proven donk that makes good fat hp and doesn't seize when the throttle is opened (or closed). The CBR is at the bottom of the list. We are keeping an eye out for a CBR150 rolling chassis...

[bucketracer]

The numbers in the F5 50cc class is starting to pickup with some seriously good riding. It will be great to see your RG50/RS chassis bike out there.
