    So my 350 ran great prior to the winter. as my relatives told me. I received it today and I wouldn't start so I put a new spark plug in. the battery was weak and I didn't realize it had a decompression switch. charged it, and with the choke half way it started up, but sounded like it would shut off at any moment. would stall if I moved the idle screw or give it some throttle. so I let it run for a good while and it sounded strong, yet turn off the choke and she went dead. with the choke halfway ran again. some throttle and she would die. I figure its the carb from sitting for 9 months. pulled it off cleaned the shit out of it about to reinstall in an hour or so. didn't appear overly dirty but It doesn't take much. the lower gasket is weird, like it isn't a bw one or something. it leak gas there and the shape is natural to the surface it supposed to be on. and its like the previous owner didn't remove the old one. i'll take a pic.

    Anyone have any idea where I can find one. The pilot jet pn 2JN-14342-23-00 seems to be unavailable anywhere. Anyone have links, leads, spares ect?

    This sounds like a plugged pilot jet.Since the hole is very tiny,you need to remove this jet and verify that you can see light through it.If not,it is plugged.If you cannot see through it and cannot blow air through to clean it,it may be gummed up and you'll need to push a small piece of wire through to open it.
    Then verify there is no other dirt in the carb that will plug it back up when you assemble it and try to run again.
    For old machines like ours,fuel filters are your friend.

    Paging Mr. Bigwheel to the carb adjustment phone....

    I don't have that carb or a manual so I'm sorry I cannot answer your question.

    Hi Guys,
    I found a BW200 that I'm interested in. I do a lot of trail riding. I currently have a CRF230F and a PW50 for my 4 year old. Some of the trails here in FL are very sandy and hard to ride. If you've ever tried to ride a dirtbike in sugar sand you know what I'm talking about. I spend most of the time just trying to keep the dang thing on 2 wheels. How do the BW's handle in the sand? Those big tires look like they were made for sugar sand. Does anyone have any experience riding a BW in sugar sand? I think this might be the perfect bike for my wife too. I'd like to get her out on the trails with me and my boy. She's open to the idea but she thinks my CRF230F is too "big and scary".

    also, what's the best way to pull the diaphragm set from the carb. (diaphragm itself is removed , but what about the pin spring etc.) nervous bout using plyers

    BW's are awesome in sand.The big tires float on the sand instead of digging in like a narrow dirt bike tire.
    They also have a nice low seat height that helps them feel small also.In my opinion,you would not regret the purchase.
    I have had 3 BW's over the years.
    I think others here will agree.

    Thanks for the reply. I'm going to see it again tomorrow. The BW200E that I'm looking at is in great shape. The seller wants $2000 and he's pretty firm on that price. Does that price sound about right for one of these? How do they compare to a FatCat?

    Deaver,

    I'm currently 4,700 miles from my manuals, so I have nothing to offer, other than my hazy, inaccurate memories for another week.

    I hope you get the carb back together and running without too much effort. It has to be frustrating to wait that long and not have the bike ready to go.

    Regards,

    Mr. BigWheel

    thanks, my parts just need to be picked up by a friend and i'll start at 2 full turns and work my way back 1/4 turns to max of 2.5 turns as recommended by a friend. should be riding the weekend. gonna paint the oem muffler which is in fantastic shape, aside from the bolts that hold the pipe it to the engine, they are completely frozen. i'll leave it attached and tape it all up and spray it.


    I have the owners manual and its very basic, very little mention of the carburator. unless u have a shop service manual i'll be shit out of luck.



    on another note where does everyone buy oil filters, anyone got a link. also do the lights only come on when the engine is running?

    wingnut racer,

    If you are looking for any part that starts with 2JN, that usually implies that it is a BigWheel part that is not shared with any other model. Unfortunately, that also means that they are not available if you can't find them at a Yamaha dealer. Neither Teikei or Yamaha offer support for the TK28.

    Deaver,

    It is normal for the lights to operate only when the engine is running. They are spit off of the charging system with their own coil under the stator cover.

    The oil filters are nearly a generic item for Yamahas, as they have been used in many of their models. I just paid $13.50us to buy one from my local, friendly Yamaha dealer. If I had planned ahead, I could have had some filters delivered to my door for $3.50 each from an ebay vendor. Of course, they are most likely Chinese knock offs, but that just encourages me to change my oil more often...

    Regards,

    Mr. BigWheel

    I use the little clear plastic ones that you can see the filter inside.
    About 1.00 inch in diameter.

    jrozar,

    Buy Dudetomm's bike:

    http://orangecounty.craigslist.org/mcy/3826128157.html

    It's nicer than a lot of them, from what I can tell.

    The standard advice concerning BWs is:

    1.) If you need OEM parts, then Partshark is your best friend

    2.) If you are looking for discontinued or obsolete parts, eBay is your best friend

    3.) If you are looking to buy a BW, Craigslist is your best friend

    4.) If you own a BW, you have no friends

    Regards,

    Mr. BigWheel
