Header Temps

I'm a fan of pulling the carbs and doing it right.

With practice, the carbs can be removed and replaced in an hour, it's pretty simple.

Add another hour to clean and blow the passages, a quick clean, and if that looks good, you're done in 4-6 hours unless you are really good.

Double those times if you want to truly do a deep clean.

NGK Standard plugs, always.

New plugs in, mixture screws set correctly, carbs synched, it is running and idling much better. No more pops/backfires. I have yet to actually go for a ride on it but given what I've encountered so far by the PO's, I will still end up getting 4 rebuild kits, pulling the carbs and giving them a nice ultrasonic bath and then running brushes through the passages, shooting some carb cleaner through them, blowing air through them and then maybe another ultrasonic bath/air before going back together. I wish my ultrasonic cleaner was big enough for all 4 carbs to fit at one time. Thanks for all the help and advice so far. Input is always welcome. Hope you all are having a great weekend.

Carb rebuild kits as well as the screw and O-ring kit ordered from RPM last night. Sounds like I will have a weekend project coming up pretty soon.

Try and use an ultrasound bath for cleaning...

I'm going to. My plan was to separate the carbs, disassemble, soak them for a little while, run brushes through the passages, put it in the ultrasonic cleaner, run brushes again, another ultrasonic, compressed air and reassemble. Maybe overkill but why not?

As long as you are not reaming out passages or jets - there is no such thing as overkill when cleaning carbs gunked up  with todays gas!
