    I can't find a way to post it either. I can't even upload it to my YouTube...it goes to 95% processed, then stays there and never goes any farther.??

    Video must be uploaded to a hosting site like Vimeo, or Youtube..then hot-linked here.

    FWIW...most 88cc-euqipped bikes top-out in the high 40s. You're doing exceptionally well.

    I think maybe sometime I can borrow someone's smartphone and make an uploadable vid. I like the phone I have because its extremely tough and waterproof. All my others kept getting killed somehow. I guess I could go by a US Cellular store and see if they have an upgraded version or something similar. Its around 5years old now.lol
    Thanks for trying anyways kirrbby

    It is overbored, fully broke in, I weigh about 160, stock carb has #60 main(stock is 58), needle clip is 2nd from bottom, NGK6 plug, pure 87, new points @.016, 14/35(overgeared), 30psi in the tires, valves .002in and .003ex, I also had my head way down.lol

    On a flat, no wind, ect., it consistently will top out at 48, but no more. Its when I put my head way down, it creeped to 50. It was a struggle for it. I don't think I will push it that hard anymore. I usually pamper this bike and its very well maintained.

    For its first 800miles or so, I never held it at constant speeds, monitored its temps for the first 600 with short trips, and changed the oil religiously every time it started to get dark and no more than 250miles.
    The last oil change, I added about a shot glass of Prolong. It lowered the temps just a little and didnt effect the clutch.

    Wish it didn't have so much noise. Some is wind, but for some reason, the phone really picks up the rattle resonance of the exhaust guard. Dont even hear it when your on the bike.

    Camera audio picks up all kindsa weird noises you never noticed before. It can also add/create evrn weirder sounds, not made by the bike. If one can discern which is which, it can be a very useful tool. Things like stiff chain links can be heard much more easily & clearly this way...early enough to prevent problems

    I never thought of using that as a tool. I would guess, with a high quality microphone and high quality playback system, it would be a great tool.

    IDK that mic quality is a big issue. The internal microphone of any GoPro is all I've used in recent years and it's been good enough. Wind noise changes the playing field and they (GoPro) has done a good job with that.

    A chain with arthritis will be heard as varying engine pitch, with a consistent beat frequency/pulsation rate. It's otherwise very difficult to notice at road speed, with all of the normal wind & mechanical mayhem, that is motorcycling, going on around you.

    OTOH, I once heard what sounded like spark knock, but at the wrong frequency for the engine rpm. That one turned out to be the camera mount rattling in the wind...I learned why those silicone thingies are included with camera mounts.

    Those are just two examples that come to mind. There are many other riders here, with their own experiences.

    I think its time that I get one of those GoPro's. Maybe THEN I can figure out how to upload vids.lol
    Dont know if the uploads will work on a Windows 7 laptop though.

    CJ,
    did you have to replace the spring guides on the forks? Mine are worn out and I cant source a replacement.

    No, I didn't. Mine seemed fine ..and tight. Maybe racerx can chime in. I didn't even think about those and have no idea where to get them.

    I would check Honda first. Cant go wrong with OEM.
