Hello TT Community! I am totally broke right now but want to ride with my 14 yr old son who is literally addicted to dirt biking. So recently I found a 98 YZ400 that is in very good shape but "needed some carb work" for $600. It starts after some work but won't idle. I'm pretty mechanical and have rebuilt carbs on CRF 70, 80, 150 and Suzuki DR650s. So I'm thinking this is a no brainer...pick up a bike in good shape for $600 and put in an afternoon with some Dokken and ice cold beers and start ripping. Now from hrs of reading YZ400 treads it looks like these carbs are junk and parts are hard to find and I'll need to spend some money to move to an 05> YZ450 carb. So, I am looking.... In the mean time I do have several questions for you gracious experts that are willing to help a noob out: #1 I did take the carb apart and cleaned it up some and found out that the serial number says it's from a 98 WR400 - not YZ. Wierd. Anyway also noticed that the pilot screw assembly was put in wrong (washer then o-ring) and it was turned in 6 turns when the manual says only 1 1/4 for 98 WR400 carb. So I fix that and am stoked thinking I may have fixed it! But I can't get the freaking throttle cables to actually work with the throttle when I go to put it all back together. &%$#@!?! I've spent an hour or so putting them on and taking off. There is absolutely no snap it just hangs there. I made sure both were attached as they were before even took pictures prior to removal. Any thoughts on what I may have done wrong?? #2 I was just curious about the TPS and CDI and ran some tests on them. The TPS tested fine but when I tested the output voltage on the CDI nothing came back - very well could have done it wrong. If the CDI was bad would it still start and would I be able to ride it down the street and back and then it may die? That's it for now. If I could get the freaking throttle cables back on I could see if I fixed something with the pilot screw. But am now also concerned that my CDI is dead. Thanks again for any help!!
