What have I done ... Help please

[MacKrell17]

Ok so a good few weeks back I started getting some noises from the front sproket. Tony suggested that it was the chain hitting the aftermarket exhaust and guess what... he was dead right. Cheers but I did also needed to change the chain and sprokets. The front one in particular looked like it had never been changed. Sharp teeth with a visible twist So got new chain and sprockets changed them and now the bike won't start. Not even a promise of firing. So here's what I did, and I can't think it would have an effect but if anyone knows different then please let me know.
I took the front sproket cover off complete with the clutch cylinder. The pushrod came with it about half way I reckon so I shoved that back in. Cleaned a hell of a lot of crap from around the sprokect changed it over (kept her in gear whilst I undid the bolts and re-torqued). Changed the rear sprokect, installed the chain put the sproket cover complete with clutch cylinder back in place. Had the battery on charge so loads of power. Tried to fire her up and she just isn't interested . I can hear air being pumped out of the exhausts, so definately turning over. I pulled a plug out and checked the spark and it's sparking no problem. Doesn't look amazingly bright but it was in direct sunlight, so probably stronger than I thought. I can smell a bit of petrol but not that strong. So put the plug back turned her over loads, pumped the choke and then checked the plugs again. Now at this point I would expect a very strong smell of petrol and the plugs to at least be damp but no. Plugs dry as and still not the strong petrol smell. So the logical conclusion is that I have trapped a fuel line somewhere, but I can't find one, and all the work was down by the final drive and no where near the fuel system.
So before I start to strip down the fuel system and start flushing out lines, does anybody have any ideas? or is there a common fuel blockage?
The other thing I noticed when moving the tank around is that there is something rattling around in the tank (sounds substantial like a bolt) and I'm pretty sure I haven't heard that before. Anyway I'm pretty stumped ... to be fair she is a fairly abused storm but normally runs like clockwork, did the RBLR1000 and she didn't miss a beat, three days after this took her to Assen and no problems at all, then used for work etc... up until now the most reliable bike I have ever had and she's been with me since 2004.

All suggestions heartily welcome.
Cheers
Neil

dunno how it works mate, but you got a switch on the side stand near the front sprocket, you aint caught the wires to that? if you have it might not start. like when in gear and you put the stand down, it will cut out. if you havent had the tank off i no idea other than side stand switch

[MacKrell17]

Yeah I checked this one. All is good. I just don't get it. The bike worked great (apart from the 'orrible crunching noise) all I've done is put new bits on and cleaned the s#it out and now she 'aint happy.

if it's cranking it isnt the sidestand switch cos if it was, it wouldnt turn over.

i think you've pulled the vacuum pipe off the fuel tap, or put it back in the wrong place.
the rattling you can hear is the fuel sensor - there's 2 types, on the older ones it's a levelsenosr / switch, and on the newer ones with a fuel gauge, it's a rheostat with a float on the end.

thinking about it, if you can hear something rattling, it would be the float, so is yours a newer one with a fuel gauge & 19L tank>>> in which case there is no vacuum pipe (or fuel tap)

check again that the pipes aren't kinked when the tank is in place - i had issues with mine at op storm and it died on me twice, only running on one pot, then wouldnt go at all - the main fuel hose was twisted like a pigs tail!
silly question, but have you got fuel in it?

[MacKrell17]

Thanks Benny, not a stupid question with fuel and it was pretty low, but I thought that too and added an extra couple of litres, and yep I have the later 19l tank.
Thing is it doesn't seem to fire at all. Not on either cylinder so I reckon any blockage or twisting is as the hose comes out of the tank before the "t" to the carbs. Looks like it's the tank off time this afternoon. will keep all posted in case it's some weird quirky thing .... tbh I reckon it will be some stupid mistake I've made putting it back together somewhere along the lines ...

[tony.mon]

Once the tank's off you should see if the lines are trapped or in the wrong place, but as you hadn't disturbed the tank I can't see how that would have happened.

But as a quick check just fill the carb lines with fuel and crank it over. It should have enough fuel in the float bowls and lines to crank, fire and run for maybe half a minute before cutting out.

Could you have caught the choke cable assembly while pulling the front sprocket cover off?

[MacKrell17]

SORTED IT
Thanks guys. As to the problem well it was a simple case of a twisted trapped fuel line. Don't know how it happened really ... must have begun months back when I was faffing with the air filter and had the tank off ... so the fuel line was trapped at the base of the tank and must have worked it's way backward cutting the fuel off. Weird because when I rocked the tank backwards over the seat unit the line straightened out so didn't look trapped. Put the tank back and line snags. Anyway, filled the lines and it fired up so that meant a blockage somewhere ... connected it to the car so I could give it loads of juice and bingo, up and running albeit with the tank standing on it's end on the seat. Now all that's left is to throw it all together, not trap any lines and give a blast, roll on the weekend!

[benny hedges]

see thats how you might've done it, by putting the tank on the seat, putting it back and putting a full turn on the fuel pipe, instead of turning it back 180 degrees.
did exactly that the other week at op storm meet.

easily done! bet you don't do it again tho

[MacKrell17]

Thanks Benny, I reckon that's exactly what I did .... Doh I'm planning on a bit of bike modding over the winter but on this form it doesn't look good! Still just booked the day off on Friday so i can try out what the storm feels like with a 15 tooth sproket on the front. Should be fun!
