Hello dear readers,
I found a lot of questions about 2003 Honda Hornet PC36 motorcycle with difficult cold start problems on different forums, but none of them has solved this problem.
2003 Honda Hornet cold start problem symptoms
In a hot weather your bike is fine, or you have to apply just a little choke to start it. When the weather gets colder, you will be unable to start your motorcycle with choke on (or off) or your bike will start more hardly.
So you have to apply a little bit a throttle, if you apply more than necessary the bike will flood itself and will die.
Honda Hornet cold start problem solution
The problem is quite annoying because it’s very hard to find.
Every japan made engine has a lot of vacuum hoses that regulates the engine.
With the time, this hoses is starting to dry and make a hole into them. So your hoses is no more isolated from the environment and they are unable to keep the vacuum. If you heat them up, the material expansion will compensate this holes, and they are working fine, but with the cold weather they start to leak again.
The solution is to change all of the vacuum hoses of the carburetors with NEW ONES.
As far you remove a lot of things, don’t waste the time and also make a carburetor synchronization also!
This is it, if you do all of the things correctly, you will have again a 2003 Honda Hornet starting at low temperatures 🙂
