    ignition timing advance

    I know you can advance the YFS200 blaster by 3-4 degrees and gain a great deal of power(2-3hp). What about the old school, YT175? The blaster is a revision and updated version of the YT175.



    Here is a picture of the timing from the manual:

    If adjusted, how much? or what should i be looking to achieve when adjusting?

    Vito makes degree keys for the blaster. i would say they should probably fit. I think up to 4 degree advance is usaully ok. I will look into it when i get a chance, and i will try to post here when i find out.
    Any one have some info there?

    what is the setup of the trike you want to advance the ignition timing on? mostly stock? also do you know where there is a timing curve chart available like this one for the blaster? or other models?

    most, mostly stock blasters benefit from a 3-4* timing advance on the stator plate. you can do this your self by notching the plate and turning it clockwise. it is best to use a degree wheel to get this spot on. but these are really close to 1mm=1 degree. i would reccomend running it on 93 MOR with the advanced ignition timing to avoid detonation issue's. hope this give you some insight, they are simliar engines.

    Just to clarify for those that have not had there YT engine apart yet (me).
    The degree key will work in the YT but has the possibility of breaking?
    Does the YT have a moveable stator plate?

    The plate isn't moveable... but you can make it move.

    I've got a second plate imma measure out and notch over. Give me some adjustments.

    Interested to hear as well! I've been learning about ignition advance/retarding some and it's backwards of what a 4 stroke wants and what I originally though. The theory says that you want as much advance low in the RPMs and as little advance at higher RPMs.
