Hello all,
Picked up an 82 Seca400 recently. Spent the time to rebuild the carbs including new shaft seals, jets, float needles and did a thorough cleaning with an ultra sound bath. Unfortunately the last owner turned the air box into modern art and had to switch to air pods. The bike definitely ran last in 2019. With the carbs installed, hit the starter and engine ran at idle speed but would NOT rev up and quickly dies. At this point I’m not even sure that I’m getting any oil pressure so I thought I would ask questions before I go any further.
1. Do I need to up the jet sizes due to the air pods?
2. If so, what jets sizes might be appropriate?
3. Is there a way to determine if I’m getting oil pressure besides the dash light?
Thanks to all
