1986 Radian 600. So just got my carbs back from being professionally rebuilt. Hooked them up, fired it up, checked for vacuum leaks, synced them and called it a day. The bike was idling well so I assumed all was well. I got on the highway and realized that I my top speed was about 65mph in 6th. The bike pulls strong up until about 7000 rpm's. After that it just refuses to accelerate. On my way back home the idle was out of wack. after reving it would hang around 3500 rpm before returning to under 2000. The idle was also slowly increasing as the engine got hotter. I assumed I had a vacuum leak that was causing it to run super lean. I checked for leaks by using an unlit propane torch with the bike idling and watched for a bump in rpms. No vacuum leak as far as I can tell. The PO installed aftermarket jets of unknown variety, im pretty sure theyre one of the ones that come in that dynajet stage 1-3 kit. The PO also installed those aftermarket adjustable needles. The person who rebuilt my carbs said that he replaced the main jets with oem ones but left the needles in the position they were in when he received them which was the needle on the highest setting (the needle goes as far down into the jet as it can). The bike ran kinda shitty before I sent in the carbs, but now it runs super shitty. My best guess is that it is either running super lean or super rich. I have a feeling its running lean. The bike starts up right away and idles decently so I'm assuming there's just something going on with the main jet. Any advice would be appreciated. Thanks in advance.
