Well if you only saw the one on top tells me you have the LINHAI horizontial motor:

Does your motor look like this:

Here is a VIDEO for the LINHAI motor on how to adjust the VALVES:

You may not have to take everything this guy did but it shows how to do it bringing up to TDC and such:

Yes that is my motor.. will get feelers tomm and adjust properly. And also the spark plug will pull and post results.. thanks... but any other ideas?

[Alleyoop]

Nope, once you adjust them right you will get your power back.

Thanks!! Ok on the video it says top at 10mm and bottom is 18.. which contradicts your settings.. which should I go with?

If I had to remove all that stuff just to adjust the valves, I would junk it.... I just looked at that video and it would cost a pretty penny to hacve it done in a shop. I do the Magnum in just a few minutes, no panels but the one screw under the seat and your on top of the intake and the exhaust is just reach up under and go to it. Now the Honda Reflex is one screw and open a the hatch and all done on the side of the motor is just 5 minutes or less.

[jenningsjosh]

Its much easier on my bike.. they are both easy to get to but gotta get gages..

[jenningsjosh]

The timing might b hard to get too now that I am looking at it... I might jave my hands full for awhile tomm.. but what gaps should I set them at

[Alleyoop]

Go by my settings 18mm is HUGE he maybe meant to say 8mm for the top which is .004 inchs and bottom exhuast 10mm which is .005 inchs. He was probably nervous he is not a professional movie star(HAHA).

TOP INTAKE .004 INCHS and BOTTOM EXHAUST .005 inchs and you will be fine.

Is the timing a must? I mean if I can get away with not messing with the timing it sure would make my journey tomm easier.

[Alleyoop]

Because you have never done them, YES IT IS CRITICAL you set the timeing at TOP DEAD CENTER ALIGN THE MARKS so that the ROCKERS ARE OFF THE HIGH LOBES ON THE CAM. Then you can adjust the valves.
Otherwise if you set them, they it may not be at TOP DEAD CENTER and you may damage the motor.

Ok I have my timing apart... I see on small line but nothing to line it up with. I have a pic but not sure how to post it on here

[jenningsjosh]

And I also have a pic of the spark plug... it looks like normal though.. no debris or black or white ash
