A rich gas mixture has more fuel and can cause pops right? and a lean gas mixture has more air ???? BTW what are some symptoms of a mix being too lean?? :confused

There's a TON of information available if you do a web search on fuel mixture.

The biggest problem with running too lean is excessive cylinder temperature potentially causing valve or piston damage.

The easiest way to get some idea is to closely inspect the spark plug tips after they've been used for a while.

If the tips are black you are running too rich and building up carbon deposits.

If white, you are too lean.

The ceramic at the tip should be a light brown color and the tip should not be burned or fouled.

A good example of plugs is usually found in the back of most auto manuals...usually has 8-10 pictures of plugs, and different conditions.....someone remind me, and I'll scan and post the picture tonight from one of mine...:laughing

(little info from factorypro.com)

If the engine has a "wet" rhythmic, soggy area at full throttle / 3k-4k rpm, that gets worse as the engine heats up, lower the fuel level by resetting the float height 1mm greater (if the original was 13mm - go to 14mm). This will lower the fuel level, making full throttle / 2k-3k rpm leaner.
If the engine is "dry" and flat between 2k to 3k rpm, raise the fuel level.
Example: change float height from 15mm to 14mm to richen up that area.

Warning: If the engine is left with the fuel level too high,, the engine may foul plugs on the street and will be "soft" and boggy at part throttle operation. Adjust Floats to raise/ lower the Fuel Level.

Reference: a bike that runs cleanly at small throttle openings when cold, but starts to show signs of richness as it heats up to full operating temperature, will usually be leaned out enough to be correct if the fuel level is LOWERED 1mm. Check out and RESET all: Suzuki (all), Yamaha (all) and Kawasaki (if low speed problems occur). Needless to say, FUEL LEVEL IS EXTREMELY IMPORTANT!!!

okthis is the situation carb bank 1&2 are light tan. carb 3&4 are black so 1&2 are fine and 3&4 are running rich bike action is this at low rpms very boggy and sluggish about 3k - 4k sommths out nicely and is very responsive I love my bike's action at 3k and above rpms. so just checking my understanding ........ I need to make carbs 3&4 more lean guess I am pulling the carbs off again :mad

Wait!!!!!!!!!!!!!!!!!!!!!!!!!!!

How old are the plugs????? the best way to check them is get a new set. Go around the block and make sure you hit every part of the RPM range. Then take them out and check. They could be skrewed up from prior problems.

Kool man:thumbsup :thumbsup

You didn't check the float levels when you had the Carbs off. It's a quick and easy thing to do a lot of people forget about:nono
