Carb sync gone bad
« on: 26 October 2015, 10:47:52 pm »
Okay, I managed to mess up carb syncing on my 600 :( I was given an old car sync (vacuum type)... I had a feeling it was not really too accurate. It's the type with the funny plastic taps that adjust vacuum flow; I used one ages ago and it was not too bad. With this one it was either very temperamental, or not responsive enough. I don't know why but I thought  :evil I'll give it a go anyway... now it's worse than it was.

The question is: is it worth buying a new set of these vacuum-gage ones or should I go for Carbtune straight away. Also, it sounds a bit worse now, and my clutch rattle got worse too :( can I still ride it or could this cause damage? I need to get to work, and if it's for the sake of the Fazer... I can take a bus for a day or two  :rollin

Thanks : )

Should be fine to ride it. Have your gauges got a leak? I'd get a carbtune but the other style should do the job.

You have to look at the bigger picture.
I bought a used one for about £45 a couple of years ago, you'll probably be looking at up to £60 now, or less if you're lucky.
But mechanics round my way now charge £55+ per hour, and they will charge you at least an hour to do it for you.
As i've already used it 3 times i'm effectively quids in, i've learned how to do it, and my bike runs sweet.
Plus i still have it at my disposal whenever i want. It's normally a job i'll do on a nice dry sunny day in summer when i've got a bit of time, and patience, to spare with no worries of rain, wind or cold to annoy me.  :sun
Just make sure that your air filter is in good clean condition otherwise you can get a false reading, which happened to me on my 2nd attempt. After i cleaned the K&N filter then did it again it was a major improvement.
Make sure the bike is at running temperature before starting anything, and do a TPS check before and after syncing the carbs.

The type your describing in the first post is what I have, I found the hoses that connect to the carbs had rotted so was unable to accurately sync carbs, some new hose borrowed from work solved the problem.
