Cb250 Charging issue. Who can solve the puzzle!?

Cb250 wont provide enough volts to charge. Im stumped; Fri, 25 September 2020 04:37

Hey folks,

I have a charging issue that has left me stumped.

I thought id put all the information out there and see if any of the more talented minds out there than myself can figure out what the issue is.

BIKE:

2004 CB250 Nighthawk - Upgrade coming soon ! Wink

ISSUE:

Bike not charging, only getting 12.6v max at the battery when running.

After a bunch o test i replaced the RR, which didnt make a difference.

I checked the VAC output of the Stator and found it was only around 12VAC @ 1000rpm, 30VAC@ 3000rpm, and 40VAC @ 5000rpm. I'm of the opinion this if far to low?

Otherwise all the tests for the stator checked out (resistance and connectivity)

I decided to buy a replacement, hoping that would do the trick, but received it today and after install the VAC output of the stator is still same as before/ low.

Any ideas would be much appreciated as im lost as to where to look now.


Thanks in advanced.

Tyre Shortages

Fri, 18 September 2020 16:37

It seems the consequences of the asinine Spring lockdown have finally arrived.

Apart from what dealers have in stock, Michelin will only start delivering most models in November. Just got the news today: apparently their main bike tyre factory (Spain) was shut down for months and they are catching up with back orders only now, giving top priority to OE.
Bridgestone has most stuff available (bike tyre factory in Japan never shut down) but due to the general lockdown chaos delivery times have stretched a lot: my T31 will be here only on Thursday.
Finally Pirelli/Metzeler is in slighty better shape than the rest due to the factory in Germany having re-opened in May already but they hiked all prices by 10%. Always expensive, so really nothing new here. Laugh

Batteries

Mon, 14 September 2020 13:03

Here's some real life experience for all of those who are tempted to save money on batteries.

Honda CB1300. Bought in 2012, no-name battery replaced in 2013 with a Yuasa, still going strong.
BMW R1200RT. Bought in 2017, Exide battery replaced under warranty twice by BMW, the second already showing excessive drain at start. Yes, that's three genuine batteries in three years.

Batteries are always maintained using the same battery charger and the charging system in both bikes is as good as new.

A brand new Yuasa for the BMW is no less than €120, but the competition is half that much. As usual you get what you pay for: there's no such thing as cheap and cheerful.

CD 200 Now she's just being awkward

Flywheel puller recommendations ?; Wed, 02 September 2020 10:14

Hello all,

Next update on my grumpy CD200 1981, now I have the girl running (after some support from you guys previously, thanks again) when the engine is warm is pours engine oil out of the flywheel side of the crank, I've bought the seals ready, but of course I forgot about pulling the flywheel itself.

Can anyone point me in the direction of the correct puller to suit this bike ? Jan 1981 it was registered.

I see loads of different pullers online, all looking different, any help as always would be greatly appreciated.

Cheers Sam

CB or not CB

Help making a choice; Sun, 30 August 2020 21:36

Hello. I have a choice to make which is causing me stress. Perhaps you kind people can advise me. I am sharing a car with my girlfriend, who has daily use of it, leaving me somewhat vehicleless most of the time. This has been frustrating. So rather than buy another car, I whittled my wants down to either:

A) A Honda PCX 125 Scooter. Mpg rumoured to be up to 140. The girlfriend can ride it on her license. It has a helmet sized hold and phone charger. I can put a leg cover on in winter. It will just about be fast enough on the motorway. Can buy new with 5 year g'tee. Most popular 125 scooter in Europe. Unsure of performance on steep hills near me. Are long (300-500km) rides for jollies now and again really feasible, esp 2 up? It's hot for being nicked. Past experience of scooters suggests that any repairs will require 3 weeks of plastics removal in order to access anything metal.

B) An nth hand 1972 CB350 with (a dubious) 58000km on the clock. In running order but requires a revamp / full renovation. It's a proper bike. It'll maybe go faster, esp up hills. It's the same year as my birth. It's green (colour). It has shiny bits on it. It does about 40mpg. Lots of spares seem to be available but prices seem high. Its value might go up if I mint it. I'd be keeping a vehicle on the road and avoiding recycling and construction impact of a new one. I can put panniers on it. It goes "vroom vroom" properly and people might say, "hey, nice bike". It might be broken down more than it's not. It's more nick resistant. The girlfriend can't ride it and doesn't like proper motorbikes. I don't have a big garage for racks of spares. My dad has renovated old cars and will be dead proud of me.

C) Buy neither and stay at home, moping, but environmentally friendly.

Both bike are about 3000€. (I'm living in France)

Oh wise ones, what should I do?

Honda Benly 200 bad manors she has !

Spluttering; Tue, 11 August 2020 17:46

Hi all, just bought my first Benly, wanted one for years, the girl wont run unless the choke is full out, anything else than this she farts, splutters and eventually dies, very bad behaviour !

So I've tried cleaning the carb, replacing some of the static parts like idle mixture screw (1.5 turns out, tried 2 turns out), checked for leaks, fuel and tank are clean, timing is ok, new points, plugs, coil, ht lead caps etc, still only runs with the choke fully out !!!!

So can anyone tell me a remedy and or where the best place to buy a new carb ? as I'm thinking this can help eliminate any further problems.

Any Help would be grateful, this is a father / son project and I want to keep my boys interest going away from xbox etc etc

Very grateful in advance

Sam
