Hey oldanddirty. I'm new here too. I have 2 Recons. A '98 and an '03, both manual shift. I have removed and cleaned the carbs on these way more than I'd like to admit due to them sitting too long and the fuel going bad along with varnishing inside the carb. Trust me, I'd like to have been riding them more. Anyway, What problem are you having? What makes you think it's a problem with the pilot screw adjustment? What is is doing or not doing? There is not a "secret formula" to adjusting this setpoint. There are always variables involved such as altitude, ambient temperature, fresh gas, clean/oiled air filter, ect. If you don't have a service manual, I recommend getting one. There is a thread here with a link to getting a manual for free in PDF form. The settings in the manual are starting points, then fine tune from there. I have found that although the clip on the needle jet should normally be put on the middle groove, (there are 3 grooves on the '03 and 5 on the '98), that I had to move it up 1 groove on the '03. This is the top groove on the '03. This will lean out the fuel. I had to do this in my case simply because although the carb was clean and set up to the factory beginning setpoints apparently over time the needles microscopically wear down thus allowing more fuel to flow past the needle causing it to flood somewhat and stumble on acceleration. The same thing on my '98 Recon. Remember that everything in the carb works together and any change at one point may cause another setpoint to need to be adjusted so that the transition from one circuit to the next works smoothly. Some things to make sure of: Make sure the carb is clean, fresh fuel, idle is set high enough to allow for it not to die during adjustments, engine is warmed to operating temp (may have to work the throttle until it gets good and warm), good clean and oiled air filter, good gasket where carb mount to the head. Once it is warm and idling high enough on it's own begin adjusting the pilot screw per the manual. After each adjustment of the pilot screw set the idle back to the recommended RPM's ( I think it's about 1500). Check for good acceleration using the throttle (while sitting still). Repeat this until you have good idle along with smooth transmission to the other circuits, meaning no stumble or backfire. Raising the clip holding the needle jet will lower the needle thus leaning the mixture. Lowering the clip will richen the mixture. More fuel is not alway good, but going too lean may hurt the engine because the fuel helps keep the engine cool. I just threw this out there, but not knowing exactly what your problem is leaves a lot of unknowns for the rest of us. Hope this helps.
