Title: YZ490

Ended up trading a vintage race SL125 for a 1982 YZ490 to race at Washougal this year. So far I raced an 83 CR480 and a TT500 there, definitely a blast ripping up Horse Power Hill. :o

A little more dialing in and it will be Washougal ready! Redid the suspension, exhaust, Fat Bars and new tires:P

Checked the carb and it had the stock 490 jetting in it, which is 440 main and 50 pilot.  :o Checked on base line 465 jetting and went with 380 main and 45 pilot.  ;) Starts 2-3 kicks and runs way cleaner, might change needle clip but for my altitude runs good. I'll take a few jets to Washougal just in case.  8)

You traded an SL125 for a YZ490...  that's two bikes on complete opposite ends of the power scale...
