Enquiry abt carb servicing.

[mitosis]

Had my carbs serviced by a very reputable shop in SG, they did a meticulous job of taking it apart and cleaning it BUT after he pt everything back on the bike, he turned on my inigtion and just reved a few times and said its done.

I enquired naturally about tuning the carbs but he said that it sounds ok.

 

So my question is this, for a 4 cylinder inline 4 engine (GSX400), after taking apart the whole carb (jets needles etc) you don't have to tune the carbs? How would you know if u need to tune, is it possible to just rev and look at the tacometer + hear sound???

 

I always thought tuning is a must after carb servicing.

to tune a carb engine,e jetting(needles,etc) needs to be adjusted or changed..to know wat to change and see e results,need to do dyno runs

 

wat e mech did is based on his experience and 'feel'

[stsoh]

don't think the mech did a proper job.

 

basically 4-inline carb disassembled n assemble back needs balancing by using 4 vacuum gauges to check all carb r equibrium balanced. in other words, synchronize.

no matter how good the mech skill r, he can't tell by reving the engine.

even EFI needs synchonizing, without facts by feeling is just BS.
