2012 BMS TBX 260 EFI, Self adjusting valves? By prodigit (Read 1,553 times)

[prodigit]

There are some indications that the 2012 BMS 260 has self adjusting valves.
Not more is said about this, other than a few mentions on webpages.
Does this mean I'll never have to adjust the valves (ever)?

And any carbon deposit making the valves less efficient, can it be cleaned with some cleaning liquid (just like on my car)?
The question I basically will be asking is:
Do I ever need to bother opening the engine to work on the valves (either adjusting or re-polishing or something); or can I expect this engine to be fairly maintenance free valve wise?

Thank you!

I never heard of self adjusting valves (that would be great) how many miles on that scoot? Valve adjustments are expected until they are seated, my scoot has over 10,000 miles on it and the last valve adjust wasn't need (they seemed to be seated now) Here is a pic off a good cleaner for gas,carb, and motor.

I just don't know if the information is true, and how the system works.
Seeing some video's on how to manually adjust the valves, makes me wonder how the self-adjusting process works?

I don't want to base my knowledge on sales lies of some webpage writing down crap to sell their bikes...

Edit: Never mind! Google is my friend, and I've found quite some info on self adjusting valves. They still need a checkup, but not every 2k miles. SAV's need a checkup only once or twice in their lifetime (usually around every 60k miles benchmark).

Self adjusting valves have what are known as hydraulic lifters.
