2000 honda valkyrie\r\n on hot days waiting in
that is unusall since this is a new bike, check your oil pressure? if low on oil pressure it will result in lack of supply of oil in the crank shaft. or check your fuel pump,usualy engine parts will not work normally in high temperature.check your oil
Starter button switch keeps going bad.
If you are running more power than the stock headlamp (60w/55w) or have highway lamps tied into the headlight circuit, you are probably overloading the starter button switch. The headlamp circuit runs through the starter button, and excess current causes the contacts to get hot and sink into the plastic switch housing.
Engine tune up
I recommend you purchase the service manual for the particular make and model of the bike you are going to tune up the engine for. The service manual will list every tool you will need, and it will give you step by step instructions on how to do any job needed to be done, plus pictures to help even further. Good luck!
Bike sat for 3 years. Is very very underpowered. Feels like a 50cc. Misses at high rpms. Carbs were not cleaned or rebuilt. What should I do?
Remove and disassemble the carburetors, clean the carburetor body, replace the main jets and the pilot jets with new parts, being careful not to damage the brass when reinstalling the new parts. Reassemble the carburetors and reinstall on the bike. Drain the fuel tank, inspect the fuel tank for rust or sediment, seal with Red-Kote or Caswell Epoxy if necessary. Remove the petcock, disassemble and clean all parts of the petcock, buy a rebuild kit if the vacuum diaphragm is dried or damaged. reinstall the petcock and fill the fuel tank with premium fuel. Clean or replace the spark plugs, and check that compression is within specifications on each cylinder. Synchronize the carburetors. Change the oil, drain and refill the cooling system, flush the brake system with fresh Dot4 fluid. Check the exhaust system for possible obstructions (rodent nests). Check the air in the tires. Each of these steps is essential for safe and proper performance of your motorcycle, especially after sitting for as long as 3 years.
Had carbs rebuilt and suppose synced but bike starts hard and when running backfires whin you let off the throttle
1. choke circuits still plugged up or carbs not cleaned correctly; most people that attempt to clean their own carbs do not have the proper equipment to do it with. Most carbs have really small orifice(jets) and require really small jet drills/orifice cleaners to clear them out. Cleaning them in a caustic soak tank will clean them out but the carbs must be taken completely apart or it will damage any gaskets or rubbers parts left in it. Carb cleaning should be left to professionals unless one has experience doing it.2. Open/broken vacuum lines can make it hard to start and backfire when letting off the throttle; jets that are not cleaned out correctly can also make it backfire.3. If the backside of the inlet grommets are not sealed at the flange and have a vacuum leak, that will cause hard starting and backfire also; this applies to carbs with a flange style grommet. If the intake grommets are cracked or leaking it too will cause hard starting and backfire. Remove the carbs, wipe the head and mating flange surfaces with laquer thinner, let it dry and then reseal the grommets back to the head with rtv silicone rubber. Make sure to wipe any excess rtv(before it drys) from down inside the port before putting the carbs back on.
On a 1997 valkyrie, if
Yes, cutting the tubes can affect performance. If you wanted to change, consider a tested exhaust system. Some of the is stuff is interrelated, and the only way to know for sure involves a dyno. A dyno is not a home tool, usually.
That being said, serious backpressure changes happen more when baffles are altered, the length of the pipe often does help the exhaust to be stable, thereby allowing new exhaust to exit the combustion chamber correctly...
