i have a 99 banshee. some mods (exhaust, cool head). i recently had the carbs rebuilt and had the same issues like not idling and no cold start. once it is warm it starts just fine and runs like a beast. i took it to a shop and they said the carbs weren't synced. they synced them and made sure i was jetted right for where i live. now it runs even better and even idles, but still wont cold start.
BTW, compression is good
any help or advice?
