    A few question to thoughs who are running the Ebay 200x cam?

    Hey guys:



    Here is what I have done..... I ported the head (Blended the port bowls and cleaned up the runners to the bowls with stock valves and springs), A 200x piston (9.6:1), a DG exhaust system, EBAY cam (webcam 55-521) .340" lift 266 duration, and a Uni air filter.

    The top end rebuild of my 1984 200s is done and wondered what carb are you using with the mods I listed above ? I am using the stock carb and wanted to know what you are using for your pilot screw/ pilot jet/ needle clip and main jet settings if using the stock carb?

    I had it running a few nights ago, but I could never get it to idle right with out fowling out the plug. It ran great before the take down, but cant get it to idle for crap. I had the carb setup with 2 turns out/ 35 pilot jet/ 2nd clip on the needle/ 100 main jet before same as before the rebuild... but it has frustrated me... I had to walk away and take a break. I also had to stop work on mine since I gave my girl's ATC my coil from my bike. Her's quit running after getting the carb dailed in. Her coil was going bad. So a new coil is on the way for me.... but I am trying to get a few idea's to what my problem could be.

    Thanks!

    Ouch. I'm wondering the same on my 86.
    This is my trike. There are many like it but this one is mine. My trike is my best friend, and it is my life. I must master it as I must master myself. My trike without me is useless. Without my trike, I am useless. I must ride my trike true. My trike and I know that what counts is not the amount of miles we ride, but the time we ride together. My trike is human in it's own ways, therefore I will learn it as my brother. I will learn it's weaknesses, it's strengths, it's parts, and it's soul.

    You might need a bigger carb to allow more air/fuel to get to the motor. There are two easy choices for carbs that can up the performance on a 200s like this - 83-85 200x carb, and XR 200 carb. I think the xr carb would be a better choice, and I think the stocker off a xr is 26mm, a little bigger than the 200x. The stock 200x is 24mm I believe, and the 185/200s used a 22mm, if memory serves me right. You can get xr style Keihin carbs from 26mm to 30mm on ebay from what I have seen.
