'Plug chop' is a method used to check the main jet circuit of your carb. With good fuel (not what's been sitting in the tank since last year), a decent plug (not one with 1000 miles of goo on it), ride in a high gear (like 5 or 6) full throttle, under load (slight uphill works good). After as long as you can hold it there (unless you are worried about seizure due to too lean..say at least 30 seconds, preferably 60 seconds)you:
Holding the throttle open:
Hit the kill switch, pull in the clutch (at the same time), brake or coast to a stop, check the plug.
Do NOT...let off the throttle or slow down under compression.
That'll tell you what the main is doing. That is the jet you 'select' FIRST. The main, although mostly used at upper throttle openings, will effect EVERY circuit..especially if it's way out of whack.
Next, set your bike to high idle using the AS (given that your AS is 1/2 to 2 turns out. If less that 1/2, you likely need a larger pilot. If more than 2, you likely need a smaller pilot). Then fine tune the AS by checking for throttle response. A quick flick of the wrist from idle to 1/4-3/8 throttle in second gear from a slow roll should give you IMMEDIATE response. Likely turn the AS in a bit to get to that point.
Try bracketing the needle for best effect in the mid-throttle range. Try maybe #4 (from the top)...see how it compares to #2..select what's best.
The needle is where 90% of the attitude of your bike is going to come from. Call Sudco (1-800-998-3529) and pick yourself up a BEL, CEK and CEL needles. They're $5 each. The CEL with the #5 (stock) throttle valve (slide) will give you an MX type hard hitting ride. The BEL with be much smoother. The CEK is what you can use when you get your carb back from RB designs :) (if ron doesn't put one in there to start with).
Sorry...got off-topic. Heck...I'm off the entire thread :ugg:

How about that intake boot/reed block setup?
