    Try kicking a center port XL350 with a 10mm stroker crank and a 12.5 to 1 compression piston. Leg breaker

    Ha!
    No thanks.
    I had an XR500R and that was a pain to kick and it was stock. :baldy
    That was the bike that convinced me that an e-start magic button was a really nice thing to have for ride enjoyment.

    Your imagination.
    Sit down when you ask for the prices. Worth it.

    The new petcock arrived today and is now installed.
    Tomorrow I will have to fill my gas cans, I've run out of gas!

    There is something nice to installing brand new parts :raabia

    New parts are so nice I’ve found I forget the fact that i know how to clean and rebuild/refurbish used parts.

    Kick start Honda's.
    I got one...a XR650R 2000 water pumper.
    New to me, years ago, first ride was at out riding area, no plates yet.
    Got it fired up and took a down hill trail.
    It quit on me, and I could not get it fired again.
    My leg only has so many kicks for a 650 single.
    Left my bike in the woods and walked out.
    Returned next day with a bigger longer leg, my buddies.
    Rode to it 2 up on his wifes 250, hoping no one would see us.
    My bud, a bike mechanic off and on since high school likes to show his bike wisdom, so gave the XR the first kicks of the day.
    He found the choke lever set at half way.
    Hum...hum.....dang....really ? ?
    Really not sure how that happened..but it fired off and all was good.
    The fun part was the ride out where I had to remember all the paces I stashed my riding gear and tool belt on the walk up hill.

    That's bad, but not as bad as pushing a bike because the "Run-Stop" button got pushed... :baldy


    My brother and his friend kicked my brothers new bike about a million times and pushed it up and down the street again and again. :baldy
    I came home to see my brother so mad he wanted beat his new bike to pieces with a sledge hammer, the set it on fire and burn the thing to death. :devildog

    I said I would give it a try and they both laughed scornfully... :dirtdog

    You can guess, I turned the key on, switched the button to "Run" and it started first kick. :nod
    Watching them realize the dumb mistake they made was when I laughed until I had tears running down my face. :imaposer

    Ah, youth :jkam :jack :imaposer

    New petcock installed and no leaking. :thumb

    I also mounted the Ricochet skid plate and finally remembered to put the bike on the scales.
    I weighed one wheel at a time, several times for confirmation.
    With half a tank of gas:
    Front 102 lbs.
    Rear 102 Lbs.
    Total 204 lbs. (for the math challenged) :D

    That means ready to ride with no gas it is is just under 200 lbs. :jkam :ricky
    (I said "ready to ride" not ready to ride for 3 hours)
    One of my peeves is the mixed ways bikes are weighed. :fpalm
    I feel strongly that they should all be ready to ride with no gas because a bike with a larger fuel capacity gets the rep of being "heavy" while a bike with a puny tank is viewed as "light" even though they may weigh the same without fuel. :loco

    I had hoped to take a little ride on the bike tomorrow but we had a warm spell that melted a lot of snow that then froze overnight turning the entire town into an ice skating rink.
    Ah, well, I can wait and have other projects to work on and it is getting colder anyway.

    Here is the local weather forecast:

    That would probably be a hilarious fun ice bike. Put a bunch of sheet metal screws in the knobs and go rip!

    True, I live in the banana belt here. :jkam

    Anchorage, the vacation destination for Fairbanks folk. :D
    Fortunately you are only an hour and a half from here in case you want to warm up. :beer

    I installed a quiet(er) insert in the muffler and it makes a real difference.
    Still sounds great but not near as loud as straight through.

    [​IMG]

    It fits like this inside the muffler:

    [​IMG]

    The small end has a removable internal end cap (held by the screw) but if you remove that it becomes a straight through pipe so it defeats the purpose.

    That is actually one of the mufflers for my Rickman that I am putting them in now since the little 200 sounds good.
    As usual I forgot to take pictures installing the one in the 200 muffler.

    I glued on strips of old inner tubes to the skid plate and clamps to try to protect the frame paint:

    [​IMG]

    And rolled off the work table again

    Light bikes sure are easy to move around the shop!

    G’day James
    As you know I’m building up a CT200 Auto AGventure bike
    Interested in your front fork set up
    Did you weigh the RM85 forks compared to the XR200 forks? Length comparison?
    Going to try and fit the lightest forks I can as HP is a limited item on my bike

    I didn't think to weigh the forks, either the stock Honda or the Suzuki RM 85. :baldy
    The Honda forks are very light since they are so spindly, but longer and for a 21" front wheel.
    But the RM forks don't weigh much either even thought they are much larger diameter and USD.

    The RM forks are shorter and designed for the 17" front wheel which is why my bike is low in front.
    I'm pretty sure you could not use a 21" front wheel.
    (they did sell a "big wheel" version of the RM85 so it probably had a 19" front wheel)
    I haven't done anything with the forks for tuning but I am sure I will need stiffer springs at the least since the fork sag is more than an inch just from the bike weight (static sag) and drop another couple inches when I sit on the bike. No surprise since my bike is heavier than the RM85 and they were sprung for a young/small rider.
    I plan to ride it as-is this summer then either take the forks apart and rebuild them myself or send them down to Rick at Cogent and have him work his magic on them.

    Not much help to answer your question, I do wish I had weighed both sets, and both front wheels to be able to compare.
    Ah, well, maybe next time.... :dirtdog

    If you search around a bit, there are guys running CR85 forks on their XR200s with the 21" wheel. They claim it to be a good weight loss. I recall that getting the wheel put together is somewhat expensive.

    Yes, over on the Thumper Talk website there are a few who have used the Honda forks with custom 21" wheels.
    I don't remember the details but it seems like there was some work involved to make the forks long enough to not bottom out with a 21" wheel.
    Since I am using a 21" I didn't focus on what they had to do.
    Anything is possible, if you can afford it! :yikes

    The 185 lbs XR200 is magnificent but it has a custom frame that really helps lose weight, he bought it used at an excellent price, and he is running trials bike ultra light wheels and tires (I think).
    I rarely look at TT though because the website is obnoxious with all the adverts.

    Morning @JagLite

    Your using a 19" front??

    Think I have located a CRF150FB USD forks for the CT200AG and will probably retain the 19" front too. Just waiting on measurements to see if I can make it work out.

    Excellent find!
    No, I am using the regular 17" front wheel that is fitted on the standard RM85.
    They do (or did) make a "Big Wheel" RM85 that used a 19" front wheel.
    The regular RM85 uses a 14" rear wheel, I don't know what the Big Wheel version uses.
