hi guys
have recently purchased an 04 550, it has a prorider end cap on the muffler and was just wondering what is a good starting point for the jetting as it ran well in the warmer weather but no as good in cooler conditions. any 1 have any experience with this? also l ran the carb hoses up under the seat(except for the overflow), would this have changed anything?
cheers
Greetings Madpugs,
Welcome to the site.
First thing we all need to know is your riding conditions (area,altitude, temperature) and what jetting you currently have in the bike:
Current needle and clip position.
Current main jet size.
Current pilot jet size.
Current pilot air jet and main air jet sizes.
Any modifications that may have been made to the carb.
Knowing these things will help us, help you make the best of what you have.
Running your vent lines up under the seat could cause some problems as Ned pointed out. Especially if you tip the bike over and they get filled with gas and are unable to drain directly, this will prevent the bike from running or at the very least make it not run right.
A question: Why did you run the vent lines up there? If you run your bike in an area with water crossings you can simply add a T fitting to each vent ( there are two per carb vent) and run one line up under the seat for each vent, that's two total and this will solve any breather problems you have while crossing deep water.
If you'd like to read a good thread on the subject, read the $40 FCR spruce up in the fuel section by Buzzard.
