Ok, Ive just recently rebuilt the top end on my 92 250x and used all stock components except for a mildly ported head with larger valves i purchased off ebay.
When i recieved the head i compared the intake ports and i dunno if id call it a mild port job?lol
And the reason i know the valves are bigger is because i had to take some meat off the rear allen key bolt in order to pass the top of the intake valve.
This bike has a stock pipe and muffler and stock air filter with no holes drilled in the lid and i didint even touch the jets in the carb other than cleaning them.
Well i fired it up last night for the first time and it runs real whisper quiet but doesnt like to idle right.
I can set it to idle either too high or if i just turn it just tiny bit it idles perfect but eventually dies.
I thought at first it was because the rings havent fully seated yet but i messed with it for a few 20 minute intervals and still doesnt want to idle right.
My question is with this head should i change the jetting in the carb?
Or is this head not gonna work with out bigger cam,aftermarket filter and exhaust?
I dont really want this bike to be some obnoxious sounding machine so im wondering if its possible to use this head or not?
Thanx......Marc
