Damn misfire....

[lloydie]

Left side - front carb
Right side - rear carb .
I'll bring a fuel tap too

[cliveyandrews]

Could it be summat as daft as that! I'm sure it's the front that's misfiring! I'll see if I can borrow a jerry can to drain it down (or Pauline's car!) I have a jiggle siphon. Do you have my address?

[lloydie]

No txt it to me please or I'll be driving around the bend !
If it's blocked then it's not getting fuel and won't pick up .
That's why I think it's fuel related .

Do you have a front cylinder carb balancing take off fitted Clive? The hose came off of mine once and gave a similar symptom but not as dramatic. Same would happen if the stopper had come out of the pipe.
Good luck with it.

[cliveyandrews]

Not that I know of Kev, I've never fitted one - but will check that out too!

[cliveyandrews]

Well, Lloydie and I (mostly Lloydie to be honest) spent a good 3 hours plus. Swapped carbs, igniter boxes, front coil, fuel tap, there appears to be a circuit between coil and igniter box. Still no change. It just won't rev past 3,000 - dropping onto 1 cylinder. You can hear the front popping and banging. 'Tis a mystery indeed!

Shooting in the wind here but looking through the thread no mention has been made on your timing situation and where the TPS is at.

[VTRDark]

Certainly a hard one to track down this one. If it wasn't at such low revs the pulse generator would be a contender.

[cliveyandrews]

Lloydie checked the TPS - and we also did a complete carb swap. Pulse generator - is that the ignition trigger?

[cliveyandrews]

Another thought is generator breaking down, apparently that could cause my symptoms....?

[VTRDark]

Pulse generator - is that the ignition trigger?

Yes but normally it's higher revs where issues arise if that's faulty.

[lloydie]

Tps was high but on the carbs we fitted from my spares the tps was set right .
I've bagged up a genny and ignition pick up and a spare loom for testing .

[AMCQ46]

Lloydies on a mopission now, don't like to be beaten

[lloydie]

No not happy I couldn't trace it :-(
Compression test soon (sticky valve has been mentioned )

[cliveyandrews]

Daz at the bike shop couldn't even start it. I'll find out more today. :-(
