Close to getting the matches out...running issues 3tj
Posted: Sat Jul 15, 2017 3:27 pm
Bought a "running" fzr400 3tj to do a track day on a few weeks back. That's been and gone already and I'm getting close to giving up on her now (second time I've said that)
Any ideas and advice much appreciated...
Bike starts flick of the key on full choke, touch the throttle it dies.
If you let it warm up a little, slowly turning choke down to half you can get it to rev but won't go past 4K. Sounds like it's hitting a rev limiter.
I stripped and cleaned carbs three times. Same. Needles were in the wrong places, 1-4 were in 2-3. But all the circuits all seem to flow, diagphrams are good.
New coils, leads and plugs. Was getting nasty electric shocks touching leads. Still the same.
Fresh super unleaded
Swapped ignition over to a bdk that came with it. Still the same.
I've changed the carb rubbers over as revs seemed to raise a little on 2. Now all seem sealed. When ticking over it's now not making any changes spraying around them
Got 12 bikes, 9 in bits lol, this was meant to give me a break and some fun whilst putting the others back together after a house move/shed build and an operation last year on my back but has now turned into a f**king nightmare!!
Before being stood the bike was running fine. I bought it from a good friend, so know it was. It's been sat in a dry garage for 18 months, he has removed a few road going bits and taped up the loom but nothing's been cut. Is there anything simple I could of missed?
The miss seems far to precise to be carbs, it does sound like a rev limiter cutting in.
I'm running out of ideas!
