*sigh* ok, here goes...

I can't see anywhere in this thread that you've mentioned charging the battery. Regardless of anything else that might be wrong with it you're going to want to start with some fresh electricity if it's been sitting for two months.

battery is all good,plenty of oomph when cranking over,was disconnected when parked up, but may buy a new one one,not sure how old it is

Two months is not so long that things will be bung.

On the fuel tap there is a little hose and a big hose on the VT's I think. The small hose is a vacuum line so that when teh motor is turning the suction from teh inlet opens the petrol tap proper. Make sure that small hose is connected between the head and the carb somewhere on teh black inlet rubber.

How are you checking for spark? I imagine you're not getting asa good an earth on the front compared to the rear. Seems consistant with how there was no sparkand now there is some.

Don't go throwin money away on a new batt if it's cranking ok,

chuck a new set of plugs at it and a can of start ya bastard to spray in the air box (after taking air filter off)

if it won't start on ether, with new plugs, you start looking at coils (testing them) and leads (testing them) if they turn out to be ok, then someones probably fucked with timing and a manual would come in handy !

If it starts and runs on ether (start ya bastard) then it's the fuel line or tank or carbs perhaps

Also make sure that vacuum line is hooked up to one of the intake rubbers, usually on the front cylinder

I'd replace the leads and plugs anyway

the trap for young players there is that the vac line can LOOK fine but even a tiny hole or split or weep where you cannot see it is enough to make the fucker not work. DAMHIK

You can do the HRC mod to them by disassembling the fuel tap, and making it so it doesnt work on vacuum. Hint: dont forget to block the spigot where the old vacuum line went.

I think this is being over compacted for the chap.

If it's getting gas, (he can smell fuel so I guess it is), and it has spark I'm picking it'll fire up. This afternoon when you turn it over, begin without the choke. Then move it to half way if it won't start still, then to full.

My old VT had a weak spark.
It ended up being the silicone boot on the spark plug end of the HT leads. Small cracks in the silicone were allowing the lead to short out onto the head, so wrap the plug end of the leads with electrical tape before your next attempt.

Just one question on this, did you swap the coils and/or leads competely, or just swap the leads around?

You need to have the front coil connected to the front cylinder, and back coil to the back cylinder, or it's never going to fire up.

I did this, just google VFR400 fuel tap mod (same fuel tap)

They can split the diaphragm in the tap and piss fuel in to the front cylinder (DAMHIK)

Good idea

started off using the rear spark plug..taking it off of course..then when I found no spark to the front lead,I swapped the leads around,after doing that I got spark to the front plug,swapped the leads back again, front plug goes to coil 2..that's the way it was when I took them off

ok,found this interesting..I done a google search for other poor saps with my predicament and they were saying about the kick stand? apparently the vtr won't start unless the kick stands are up?? Really?
