    SL750 Bogging

    I took it out for the first time after building the top end. (hole in mag when I bought it). It starts fine and idles fine. I give it gas and the RPM's raise slightly and stay their even giving more gas. Then after you go a ways it clears out and takes off until you let out of the gas even slightly and then all over again. I installed triple outlet pump and new reeds(Boysen Power Reeds). Cleaned the carbs weren't dirty, but I am new to this. When yall say cleaning the carbs do you tear them all the way apart or just the sides and clean them, because thats wear I probably went wrong.

    Cleaning the carbs means pulling them completely apart, and cleaning them internally.

    Have a look at the Mikuni carb rebuild guides.

    Always use genuine Mikuni rebuild parts or kits.

    Every small opening and internal passageway must be cleaned out. Spraying carb cleaner through each of the tiny holes is a good thing (wear eye protection).

    Since your engine suffered a piston lean burn, it is very likely that the carbs need cleaning.

    Do not run the engine until you get the problem fixed, as you do not wat to damage the engine the same way again.

    So it would probably be a good idea to just go ahead and rebuild them to be safe. The only think that is different from stock is the reeds, they wouldn't make it run like this with the carbs set stock would they? Thanks for the help

    If the reeds are not installed correctly, or have become broken, then it could cause problems.

    Some performance reeds will affect carb adjustment. You may need to turn the low speed screw out a 1/4 turn, but I don't think that's your issue.

    Carbs should come completely apart and soaked in cleaner.

    The carbs will be coming off and being rebuilt as soon as I get time. Thanks for the help
