valve clearance gauge size

[lukasbasic]

what gauge size should I use for the super 8 150 valve clearance adjustment?

I just did my 200 mile service and adjusted the valves to .004" I also changed all the fluids for the first time and my little scoot is running great!

You can also use a metric feeler gauge set to set the valves to ~0.10 mm.

ChefRupe, I will eventually do the valves at 200 miles.  I have 30 miles now since new. How can I get a factory manual? Thanks.

I have a link saved on my laptop that I bought a "subscription" to and it has my super 8's service manual. It's a chilton or haynes manual I think. Just google it man, that's what I did.

I adjusted both of my valves to .004 inch because that's the info I was able to find online but I was wondering that since the exhaust valve gets hotter than the intake valve, shouldn't the exhaust valve gap be more than the intake?  Like .005 inch instead?

My brother is a mechanic and explained that about these little single cylinder thumper motors we have. He says the mechanics are so basic and the cam/lifters/valves are so small that symmetry is part of their design. The tight exhaust valve offers a built in form of back pressure to the motor and helps regulate the compression.

I assumed the valves should be different too but the service manual says same and so does my mechanic.

Cool, thanks for the info.

Several of us have received from our dealers a service manual in PDF format for freebies.

So same referring to 0.004 or 0.005

If you are talking about underneath my seat it doesn't have a sticker

The side of a pop can or beer can is .05mm, exactly the right thickness for checking valve clearance. How excellent is that?

Sorry for the misinformation. ....my two scooters have a buch of  info & safety stickers all over, under and on the scooter body and frame. Much information on them: tire size, air pressure in tires, place of manufacture, VIN, date rolled off assembly line, gross vehicle weight, air quality vacuum line routings, idle speed, valve gap, spark plug gap.....etc. For instance, if you know the weight of the scooter - you can compare to gross permitted vehicle weight and determine the permissible load limit.
Thought other scooters did as well.
Strange.

Hey I actually found it. It was at the bottom of my bike by the fly wheel thanks
