Welcome To Bikes And Travels...

...It's about bikes...and travels...mostly on bikes!

Stac Pollaidh

I hope this pestilence subsides for the sake of humanity. That, and I want to see Stac Pollaidh once more - soon - not next year I mean soon!

What's New?

Welsh Odyssey With new found freedom Bogger et-al decide the best way to celebrate is by camping in a farmer's field in the rain. Fun, frolics and fabulous scenery with nothing bigger than a 125 (and vans and a couple of big bikes).
Wet 'n Wild And Oddly Familiar A much antici......pated weekend away sees everything in order for Ren except for one small matter. The weather.
The Heath Tea Rooms It's time for another micro adventure! Shropshire is the county enduring the presence of Ren and associated cohorts.
Sharon's Headlamp Saga Continues Sharon's crazy crazed headlight finds itself in the hands of Bogger. Can he fix it? Well if anyone can Bogger can.
Health Benefits Ian Douglas is musing over both the risks and benefits of motorcycling on a rider's health. Pros and cons, but he wouldn't like to be without his bike.
Tyre Trouble A'th Mill Ren, the living embodiment of stupidly stubborn, is having tyre trouble. Some of it is due to natural erosion but most of it is entirely self inflicted.
Why Not Scooters? After a passing comment from Ian Ren tries to become a better person. He fails of course, but the advantages of the step through motorcycle are quite persuasive.
A Long Long Ride With restrictions easing Sharon and Ren join several other riders for a day trip to Aberystwyth. Can their asses and brains cope with the distance though?
Getting To Grips With Glasses Our resident grumpy old curmudgeon has some bad news - he had to spend some money. Something to do with getting old and not seeing things clearly. Must be true, he still thinks he's a handsome young fellow.
A Real Ride Out Sharon and Ren venture out beyond the realm of the space between their bubble. It's a good day but not without a mix of emotions.

Sounds very like my own place that does, but I have a guard wife, a dog and three small, ferral animals to protect my nail clippings collage... Children, they are sometimes called. I will do

I'm terribly loathe to publish details of where I'm going to be at a future date. I don't wish to advertise that I'll be away from home on such and such a date because I don't want some nefarious criminal to think "Ooooh that BAT fella is on holiday, I'll pop around his house".

Mind you they'd be bitterly bitterly disappointed. The only thing of value is my bike which I'd be riding and my toe-nail clippings collection that goes back 30 years. So unless they have a fetish for random Honda clutch cables and home made tyre changing kit it wouldn't be worth the effort.

If you drop me an email RobEll I could let you know that way if I'm going to be in your area? PS - if you found the 500 a little "lacking" do take a look at the 700 Tracer. That engine is an absolute PEACH!!

CBF 125 Injector Explained Ren - The Ed¹ said :-
As the EFI has a MAF (Mass Air Flow) sensor and Lambda sensor theoretically it should work - to a point. With the bigger barrel and cams essentially at say 1/4 throttle the computer will think its a 125 at 1/3 throttle and fuel accordingly. You may run into a point though where the injectors and the size of the throttle body become your limiting factor above say 3/4 throttle. I'm not qualified to offer much more than to suggest "more research needed".

I don't know where you're from mattyf but here in the UK such a modification can get complicated legally. Your insurance would need to know and I'm guessing/hoping you've passed your test and not on "L" plates.

CBF 125 Injector Explained mattyf said :-
long story short I've got a 2010 cbf 125, clutch was done up too tight by previous owner, tried to remove, broke the spring pins, bought a new engine apparently refurbished with a new top end, they didn't replace the piston, it got scored badly along with the barrel, bought a new barrel/piston kit, couldn't remove the piston even with specialist tools.. now I need to replace the crank. (I've already replaced every consumable with plans to replace the clutch on the old engine,didn't go to plan)

now I'm inside the engine, if I was to buy a 185 barrel, uprated crank and more powerful cams would the ecu/fuel injector be sufficient to provide enough fuel or will it lean it out? I'm under the influence the fuel injector will only add the same fuel as if it was a 125.

Sorry to hear of your medical troubles Ross. I think we all got somewhat of a taste of restrictions over this past year, it has been a long Winter for us all. I miss my historic commute from South Wales to Bristol for work greatly. I've also grown a terrible habit of serial motorcycle purchases as I'm still on a search for something I gel with. First an old SV650S was too cramped, the CB500 lovely but lacking the bite I enjoyed with the SV. I'm not too overjoyed to inform you that I'm about to embark on the purchase of my third bike since gaining my full access licence just last August and I hope this next one is a keeper..I really do. I'm looking at getting a 700Tracer GT much to the annoyance of my long suffering wife. Maybe I'll get a 4 cylinder machine next? And I'd finally like to meet some like minded folks if possible at some point. Any chance of a BAT camp-out somewhere near Wales this year? Good luck Ross and I wish you a v speedy recovery matey. All the best.

CBF 125 Injector Explained Ren - The Ed¹ said :-
Perfectly valid point Upt'. The dirty and/or corroded connections can lead to the battery not charging too which would then exacerbate the problem. Give 'em a clean and slap some Vaseline on there to slow down any further corrosion. I don't know WHY Vaseline (other petroleum jellies are available) but Vaseline seems to be the popular choice for battery terminals. Anyone out there know why... is grease as good or does it conduct more?

Ed, I'm not doubting that Jon C had a dickie battery....but....I would suggest checking and cleaning battery terminals and earth connections is always a good start when elecrotrickery starts to show its ugly face.
My Optimate was starting to take longer to get up to green about a month ago. Cleaned and tightened everything and Robert's your fathers brother.
On the other forum, a member Stateside had all sorts of shenanigans starting to show on his bike. The advice was everything from a total strip down to check your battery terminals, sure enough it was a loose dirty lead. If only everything in life was so simple.

Good info Jon C and thanks for letting us know. Modern vehicles don't like a sickening battery as (this is my best guess) when the starter motor is cranking it uses up all the angry pixies leaving the computer and the sparky bits a bit short. What voltage are you getting? I seem to recall mine was around the 14 volts mark.

I hate the idea of a party nab301. All those bloomin' happy people all having fun, bah HUMBUG! In a perfect world I hope to be someplace nice with just me, my bike and maybe a Sharon. We'll see what happens with the restrictions. Lord only knows by then we could be onto the alien invasion, zombie apocalypse, meteor strike AND super volcano. I'm generally quite a positive person, I'm positive we're screwed.

Ed the sword wielder. Yes you Ren.
Please ban Henrik, 55 IS NOT OLD, I should know I passed it some time ago. 55?!?
Ban him.
And on the fuel front.....97 mpg! Did you push it the last 100 miles?
Also on the fuel front, I put over £30.00 in it yesterday. Over £30.00!

Yes, sorry, the right UK number is 82 mpg translated from 29 km/l but still shows a thirsty 250 ccm can be on par with a efficient 500 ccm. The downside on 250 GW/DL, but still I like it. Thanks for the photo-cooment, joined a local photo-club lately, to improve and get inspired, if nothing else it makes me feel young again despite being 55 :-) Norway still closed, will have to live on the memory from last year

You do take some splendid pictures Henrik - I have that "Wish I was there" feeling now. As for 68mpg? Are we in UK Imperial gallons or have you made the same mistake I've made and used the smaller American gallons? If this is Imperial gallons then I recommend trying 4th, 5th and 6th gear. I get 75mpg (Imperial gallons) out of my 500 when I'm going mental, usually 80-85 and when I went to my father's on the motorway a few weeks back I got 97mpg.

Horses for courses :-) those are the local stub-mills in Sweden, dated back to the middel-age. Today's ride was 68 mpg on the Inazuma GW250 ,... despite very low avarage speed. Guess a small car could do better :-)

90 to 100k...for a whole house!! It's a bit different in Kent...and there's plenty of jobs down here that pay less than 30k a year!

"Out of Kilter", who said recently "it was ever thus".
The price of houses in idyllic (?) areas are obviously benefiting from the bug.
So are the prices for classic (?) vehicles, auto memorabilia, old watches, etc.
But just like night follows day it will all readjust once the world resets.
It was ever thus.

Property prices are silly. My home is but a small 2-up 2-down terrace in a "middling" area (not rough but not posh either). It was built to house the workers at the Loco Works but for many years it would be considered a starter home, you know, first rung on the ladder when you're young. Now, even in it's present condition it would cost around 90 to 100k

Traditionally a mortgage would be 3 times your income. That means you'd have to be earning 30k to buy this. Now I know London prices and wages are different but 30k round here would be considered "doing OK, not rich like but comfy". If you are 25 and earning 30k you're doing great. And yet all you can get is a pokey little mid terrace for your wages. At 30k a year I'da thought you'd be aiming for semi in suburbia, but no, that'll be 160k if you're lucky and can do DIY.

Something somewhere is out of kilter.

nab301 - I ask because up to scratch we'll be back in Norn' Oyerland later this year, thing is we'll be on the north coast about 170 miles (270 km) from your manor.
