help me troubleshoot my Storm

[macdee]

carl is the longer needle in the back carb
done work on my carbs and this has got me thinking i may have installed the wrong way
just didn't no they were different lengths so its in me head now and wont leave till i check them

[VTRDark]

IIRC yes I believe so. There are subtle differences between the carbs and years too. Not sure what though. If you look at the specifications in the Honda manual at the beginning of the Fuel system chapter it list the jet needle numbers for front and rear. The needles are marked but you will need a magnifying glass to see.

The front needle is marked A1UD. The rear needle is marked A1UC.

I had to go and double check as I was starting t question myself I have my old needle sitting in my Factory Pro box and yes my front is A1UD and Rear is A1UC according to the workshop manual and I double checked the numbers with a magnifying glass.

Measured with vernier in mm

Front A1UD = 59.90
Rear A1UC = 59.95

The exact measurement is an approximate measurement as my vernier is not the most accurate and it's difficult getting the needle dead straight on it. I double checked the measurement and got a slight different reading.

Front A1UD = 59.80
Rear A1UC = 59.85

But both times the rear is slightly longer.

Finally making progress!!.

I stripped the carbs again this morning and spent 2 hours with a can of carb cleaner and a can of compressed air cleaning everything again.

Reassembled and refitted and....

The bike now runs on and off choke, and revs when you blip the throttle. Still the occasional pop through the exhaust and the occasional misfire but massively improved!!

So pilot screw fine adjustment and carb balance next. And then pull the fuel tap out of the tank and give everything there a good clean up.

[VTRDark]

That sounds promising

Man, I wish I hadn't doubted myself and startied Richard around with cam timing and stuff. Problem is when you've done some work, and the first time you ride the bike it's not right, you tend to think you've messed something up....or at least I do! So the MCCTs became the prime suspect, especially as I fitted them using the Kreiga instructions and so didn't remove the front rocker cover. At least I got my valve clearances checked while it was apart. And of course the Reg/rec failed at the same time as all this was going on, so I started looking at electrics, and in finality it turns out that I must have dislodged some muck in the tank that blocked a passageway or jet in the front carb.

Oh well, live and learn.

good work............i'm the same as you and would have suspected the other items that had been touched or just failed

[VTRDark]

I know what you mean it can be easy to question things that where recently touched/changed and one can get into a frustrated muddle. But you have to look at the symptoms and possible causes for the symptoms. A little bit of rough running (coughing and spluttering) and backfires, puddles of fuel in the inlet was crying out fuel issue. Also a few of those symptoms cry out R/R which I suspect you also have an issue with as the electrics/clocks also went a bit spazz and the low voltage readings which a fuel issue wont do.

R/R is good thing to sort out either way so no loss there, you would only end up doing it at a later date after your possibly left stranded somewhere. You have new plugs which is not a bad thing to change being a service item and their not expensive so no loss there.

Getting the CCT's done was a good move and timing all double checked for peace of mind/elimination, valve clearances checked. It's all good and in the right order. Timing and valve clearances before tuning carbs.

I'm hoping to spend the day tomorrow setting the carbs up and cleaning the tank. Can't wait to get out for a ride!!!

Sorry if some of my posts seemed muddled...I actually work quite methodically, but thinking things through and trying to make them make sense in the context of a forum is clearly not my forte lols

A big to everyone here for your input, advice, ideas and generally wanting to help. What a great forum with fantastic people!!!

Is anyone running inline fuel filters between the tank and the carbs? If so what has a high enough flow rate but is small enough to fit?

[Wicky]

I fitted some to a friend's storm after it had a respray as a precaution - A PIA to be honest as it suffered from fuel lock when the filter got wet thus blocking fuel flow so filter needed priming to ensure it flowed sufficiently. The tank has an internal fuel filter attached to the tap just make sure you've washed out the tank thoroughly.

[lloydie]

Inline filters don't work very well unless you fit a fuel pump .
It's what I've been doing the last week or so .
One inline filter was fine but the other one wouldn't refill even after being primed .

Yep I've just found that. The filter attached to the fuel line for the front carb won't fill even with my auxilliary tank in a tropid anout 2 feet above the bike.

However, carbs are balanced and pilot screws adjusted and she seems to run like a dream. Not test ridden yet as I still have to clean the tank out.

I started with the pilot screws 2.5 out front and 2.25 as per cybercarls post. At this setting the bike was running really rich and was fluffy when reved.
I ended up with the front pilot screw at just under 2 turns out, and the rear at 2 exactly. The bike starts runs and revs freely so this seems to be right to me, although it's quite a bit leaner than where I started. Does this seem about right?

[VTRDark]

Good stuff. There's no precise setting for each bike, they are all different but that sounds about right. How's the fluctuation on the needle as it drops back down to idle?
