Hello guys, I'm currently struggling to get the old 636 to start. My last ride in the fall unfortunately ended up in a slow (10-15mpg) low slide on the left side. During the winter I removed the fairings and gas tank for painting (turned out pretty sweet). To my dismay after reassembling this spring she won't start.
Observations:
- Bike turned over well, did not sputter or have any combustion
- battery has a lot of juice
- Double checked all the connectors
- Gas line has fuel going through it
- plugs have spark (grounded off of frame)
- Spark plugs are less than a year old and have about 2,000 miles on them
- Starter fluid through the throttle body did not result in combustion
Troubleshooting I've done:
- Service codes that read: 34, 62, 63 (34 and 63 are the result of after market exhaust)
- Followed service manual's trouble shooting for service code 62 (subthrottle valve actuator
- Subthrottle valves did not operate properly. They moved approximately 10 degrees, stuttered, and returned to full open position
- Checked actuator connector, resistance was within spec, voltage was checked without peak volt meter but reading was out of spec
- Checked wiring to ECU and observed no problems
- Replaced ECU which did not eliminate the problem.
- Swapped ECU Main relay (the drop cracked the side fairing exactly were the relay sits) with another zx6r and did not help
My next plan is to replace the throttle body, but most people who experience that service code don't have trouble starting that I'm aware of.
If you guys have any advice or recommendations I'd really really appreciate it.
