Hey guys, my CBR 600 is bogging in 6th gear, on the highway, its really the only gear it does it I'm, like it loses power for a second and kinda lurches.

Im trying to think what it could be, dirty air filter? Or maybe dirty fuel filter? Could someone tell me where exactly the fuel filter is located? I also am not sure about how to get to the air filter by taking off the tank, I'm not trying to get gas everywhere so if someone might be able to direct me on how-to that would be great!

Anyways if anyone has experienced this before let me know! BTW its not vapor lock.

 

Also how do I go about cleaning the carbs and jets? Can I clean them without taking them off the bike?

 

There isn't a typical inline-type fuel filter, the closest to that is a screen that sits at the bottom of the tank, which is connected to the petcock assembly - you can somewhat visually inspect it looking into the tank. See item 7 in this fiche view.

Get a manual...period! You'll need it more in the future. If you're mechanically inclined, you can manage to get to the point of changing the air filter without a manual - I worked that out before I got a manual, but I had worked on piles of bikes before and countless car. The key is your method - just taking it slowly, and being very observant during disassembly. Make notes of where everything came from, and organize the bolts/screws/parts you remove, so going back together will be intuitive - but seriously, get a manual!

As far as not getting fuel everywhere... when you disconnect the main fuel hose from the petcock, if you keep the hose up, you won't have much of a mess, but the best way to drain that down, would be to turn your petcock off, and run the bike for a while, until the fuel empties from that hose (before you disconnect it, of course ).

Again, it would be best to get a manual, and you should, but you can search this forum for threads/postings about cleaning the carbs. My F2 build thread doesn't have a "walk-through", per se, but there are a few pics of the carbs in various states of disassembly, and I know there are other threads that cover it in more depth. I don't recommend just soaking the carbs, I take them down to where I can see the individual fuel circuits, and get carb cleaner into all the passages, followed by waiting some time, and then spraying more into each circuit, and then using compressed air to blow them out. I also fully remove the float bowls for inspection and thorough cleaning, as well as making sure none of the floats are sticking, and, I pull all the main jets and pilot jets, and soak them in carb cleaner. It's wise to remove the diaphragm covers to check the condition of the rubber diaphragms, while you've got everything apart anyway.

***Whatever you do, DO NOT get carb cleaner on ANY rubber parts, from seals to the diaphragms, to O-rings - it will dry them out, and cause them to expand - unless it is a carb cleaner that specifically states it is safe for O-rings and such, like the Yamalube carb dip.***

No! (see above)

It is not possible to perform much, if any, of the above tasks, with the carbs mounted to the engine.

All that said, this is a "big" job to some, and child's play for others, so make sure you search the forum, and expose yourself to some pictures and information, before you tackle it, just so you don't find this is out of your scope, after it's too late!!

What RPM are you pulling when you get the 'bog'?
Does it do it at a steady throttle or when you 'blip' it?

You can try some Seafoam, etc. in the fuel-tank. It will help if the carbs are only
mildly dirty. It's real utility comes , as a way to keep the carbs clean, though.

Check all of the wiring harness to see if the bog is related to faulty/damaged,
wiring/connection. Look for frayed damaged wiring, melted/dis-colored/burnt-looking connectors.
If you see anything, closely exam/test whatever is connected, to that point of the harness.

Fuel filter replacemnet is a cheap easy elimination of a potential bottleneck...
and is good maintenance, as well.

Hope this helps, Ern

 

Yes helps a lot thanks y'all!
