YPVS stands for yamaha power valve system

This bike is very old...n needs lots of attention

unlike RXK,RXS...... RD it comes with a valve n radiator.

 

My suggestion is tat u flush the radiator once in a while

open the radiator cap check if the coolent is dirty n oily.

 

As for the loud knocking sound most likely the piston is worn

out but I dun think it is worth it to overhaul the bike...coz the bike

got no more value... the cost of changing the piston will most

likely be equal to the market value of the bike which is ard $200-300

 

If you really wanna change the piston remember to have yr Valve

clean up too

That pipe I bought it from LAB 10 years ago. the header was too long and it didn't fit as its meant for the Z-kia . So I had no choice but to saw away my kui-duo pipe header and weld it the that Z-kia exhaust.

Luckily I can pass inspection.

how come must take out the 2T line???

[Kenneth Lee]

cause 2 stroke bike tend to give out a lot of white smoke, So I tell Laucheh my method That is to pluck out the 2T line to the carburator,then ride slowly to the inspection centre. By doing this, you will have a section of the 2T line without 2T, so during inspection, no white smoke.

That time, the inspector use torchlight to check all the oil line, I quickly plug back the 2T line. So when he checked no white smoke... Later when I move off of the test station, white smoke again... hahaha... he saw but bo bian, already sign the paper...
