Hi, Dan some bikes get "Sun Stroke" after running fine in the morning then shut off and parked in the sun for a couple of hours on a hot day. You get back on the bike hit the starter button and nothing happens or the engine turns over but will not fire. Then you put the bike in the shade for 20-30 minutes and it fires up no problem.
The primary reason for this phenomenon is faulty wire connections in the Starter and/or Ignition Circuit. You may have a wire connection/component that makes just enough contact when cool to start and run the bike, but when parked and exposed to direct sunlight heat causes expansion and creates an "OPEN" in the circuit not allowing the bike to start. You move the bike into the shade for a few minutes, the temperature goes down allowing the connection to contract and make better contact and suddenly "it's a miracle" the bike starts. I know what you're thinking that Gremlin could be anywhere, and you would be right in that assumption, you can take your bike to a dealer, spend tons of "DRACHMA" only to receive validated nervous emotions the next time you park in the sun, then 1 week later it doesn't start. Start by doing a ground check:
Check the battery terminals for damage or corrosion, check the battery cables at "BOTH" ends for loose, corroded, or broken connectors, "INSIDE" and outside the cable harness, perform connector wiggle test and check cables with an ohmmeter if necessary. Check all common grounds for the same suspects.
The secondary reason your bike may get "Sun Stroke" is vapor lock although this is a rare scenario it does happen.

SOURCE: WONT START AFTER DRIVING. WAIT 1 HR THEN STARTS,

I had the same issue with my 1997 Astro and it was the crank position sensor. It would loose power if I were driving and shut down once it slowed down or just shut off if idling or at a light. It would them not fire back up until it cooled off. Hope this is of good help.

not sure on the exact specs but flip the carb upside down and look how the floats look to the horizon of the earth. Sounds silly but that is how pretty much all bike mechanics set them, just make them level to the earth. Good luck

My guess is there is ingress, via a leak, of un-metered air after the Mass Air Sensor. The air under the hood can get very hot on a sunny day. If there is a leak in the filtered air ducting or one of the vacuum tubes has become detached from the intake manifold/plenum then sucking in hot air will make the fuel mix to the engine to lean to fire up. Check you ducting especially where it joins the throttle for any cracks or loose joints. Check crank case breather pipe connection to duct. Check each vacuum tube, after the throttle, connecting with the manifold for leaks. Check the brake vacuum servo pipe for good connections

Need to syc carbs on suzuki 1986 gs550l motorcycle


Get a carburetor synchronizing tool and a service manual (OEM Suzuki, Haynes or Clymer). Synching a two carb engine is easy. There's only one screw to adjust, and it's usually between the carbs.

1982 Suzuki Gs 550 L will not start when hot


Hi, Zach and the usual suspects are:
1. Fuel tank empty.
2. The fuel tank has old dead gas.
3. Fuel tank bottom contaminated with ethanol sludge, dirt, water, rust, etc.
4. Fuel supply valve/petcock turned off.
5. Fouled spark plugs.
6. Engine flooded as a result of overuse of the enrichner.
7. Vacuum hose to the fuel supply valve/petcock disconnected, broken, cracked, or pinched.
8. Fuel valve/petcock or filter clogged.
9. Fuel line to carburetor or throttle body pinched, kinked or blocked.
10. Carburetor float stuck.
11. Fuel injectors clogged.
12. Fuel injectors stuck open.
13. Severely discharged or a damaged battery should have 12.5 volts or more and be able to pass a proper "LOAD" test if necessary, you may have a cursory reading of 12.5 volts or more but little or zero amperage the battery is faulty and must be replaced, AGM batteries fail in this scenario more so than lead acid batteries.
14. Check battery terminals for damage or corrosion, check the battery cables at "BOTH" ends for loose, corroded, or broken connectors, "INSIDE" and outside the cable harness, perform connector wiggle test and check cables with an ohmmeter if necessary.
15. Loose or corroded wire connection at the coil or plug between ignition sensor and ECM module.
16. Spark plug cables in bad condition and shorting check for spark leakage in the dark, cable connections loose, or connected to the wrong cylinders.
17. Ignition timing incorrect due to a faulty ignition coil, ignition module or MAP, CMP, CKP, O2, TPS, ETP, IAC sensors.
18. Faulty neutral, clutch lever, or kickstand safety switch.
19. Faulty fuel pump or fuse or relay.
20. A stuck bent or burnt valve.
21. Tilt sensor needs a reset.
22. Security system not disarming alarm needs a reset.
23. Check for engine trouble codes.

Proper start-up service for a 1980 Suzuki GS550L motorcycle.


Shoot WD40 into each cylinder to get them wet.
Change gearbox oil and oil filter. Use 10w40 motor oil in the gear box. Don't use any synthetic oils, oil marked "EC", or oil with "special" additives. Stick with the major brands; Pennzoil, Quaker State, Mobil or Shell. How bad is the rust inside the gas tank? I would consider a liquid tank liner if rusted. Google “ kreem fuel tank liner “ or go to www.http://www.4secondsflat.com/Fuel_Tank_Sealer.html
  • Lube chain or get a new chain (if needed)
  • Lube Throttle, clutch and front brake cables
  • Lube Speedometer cable
  • Grease the swingarm, axle and steering stem bearings.
  • Install a new battery
  • Clean, and balance the carbs. This will be the problem area. They will likely be gummed up pretty good. Be sure to install an in-line fuel filter before starting the bike.
