Well I have had the baja for 1 year as of today and i thought i would post up my thoughts and what I had to replace on it.
First thing that went was my Throttle/Brake servo, locked up tight. So at that time I replaced both the sterring servo and Throttle servo. In replacing the sterring servo I installed the hpi radio box so the servo would fit.
After a hour of bashing in the sand, my clutch went. Replaced with a new clutch and 8000rpm spring, also installed the km inclosed clutch cover, no problems since with the clutch.
About 5 runs in my plug wire went after a roll over on pavement. Replaced with a copper core aceel plug wire and installed the km steel roll cage.
After around 4 gallons of 100LL (only gas in my aera with no ethanol in it) the motor lost all compression. After close inspection and forum searching the root cause was sucking in sand around the carb shaft. I installed o'rings around the motor and installed a cy26.
That is all the parts/failures i have had with it over a years time. I don't jump it that much, just a little sand brume around the river that i get 3-4 feet of air. The stock plastic has held up way past me exceptions and i would recommend to anyone who wants a 5th scale and is on a budget.
Other thoughts on the Km 5b is do the carb seal mod asap if you run in anykind of dust to save your motor. Install a kill switch, it saved my baja when the servo failed, saved who knows how much money. Possibly it saved it from a total loss.
