Well, went down today for the start fo the direct access course, think this is session 1 of 6 in total? Anyway, passed this, got the cert so it's CBT Pass [good][thumbsup]

So, now, this week can get out on the Honda CBR125 get loads of pratice in, the next session for the full licence is 23rd April, so got 2 weeks to get practice in me thinks.

trying to get my damn Honda CBR125 started... doing my head in (not ran since before Xmas), think a new spark plug may be needed. Basically it'll fire and thr spark looks like a decent spark when I took it out, cleaned it off with very light sand paper... took tank off, checked all the fuel lines as nothing was getting to the spark... sprayed some easy start... however, put back on, the spark smells of fuel now so I know fuel is getting there... it's fired once, hit 5000rpm, then died as I didn't catch it in time.

So, my theory now I've plugged it back together, if there's fuel getting through... then it's the spark... gap seems quite large on it.

Will pick one up tomorrow me thinks... not sure where from near Chester on a Bank Holiday Monday though, wanna get out on this this week.

Question though, the fuel filter leads into the frame... wtf is that about? Why is it NOT inline with the fuel delivery to the carb? Sorry for ignorance here, I'm a car person!

First, get a multimeter across the battery and see what it's putting out. Less than 12v before starting it's very dead. If it reads 12+v but falls through the floor to like 9v or below when firing it up, it's dead.
Second, before you sandpapered the spark (which I wouldn't recommend) what did it look like?

Well, I'd suggest picking up a manual for a start.
However, pull the plug again and have a gander at it - I suspect you may have overchoked it and it's flooded.

If it sat since Xmas without the carb being drained before hand it may be clogged.

More to the point, could be some water in the carb from condensation in the tank - more a problem for when they're low, though, full ones don't have that problem - which is also why aircraft are generally kept with tanks full.
There may be a drain for the bowl - assuming it isn't EFI, of course.

The CBT is not a test and thus one cannot 'fail' it, you can however, be asked to come in again if they feel you need some working on. Congratulations anyway, I'm on my module 2 but not doing it just yet, want a car first, had some crazy fun on the Yamaha XJ6 I was learning on

Sounds like it to me, if its been laid up in the cold then its had time to heat up in the warm weather we had recently its probably got condensation somewhere.

You could also try to clean out the fuel float bowl of any crap and that's a good place for water to accumulate, might be worth getting some carb cleaner and carefully unscrewing the main jet and blasting it through as well as the carb itself.

How'd you find the CBR? Does it seem big enough?.... how tall are you?

Congrats, and could be the rectifier that is playing up. If you use a multimeter as suggested and it goes over 12V, then it is cooking the battery and your rectifier is up the swanny. You should invest in an optimate, worth their weight in gold as you can leave it trickle charging all winter.
