    Added a 1984 Big Red to the family

    Made a deal today on another trike. I have been looking for something similar to the 200m I had as a kid and this showed up on Facebook.



    Supposed to pick it up tomorrow. First glance looks like new gas tank is in order, along with seat cover. Bike was running couple years ago and has set up since.

    Can't wait to dig into this one.

    I'll be watching the progress...by the way, those seats ain't to hard to recover yourself. Heavy duty staple gun and a piece of nygahide(?). I'll be interested to see how you recondition those fenders.

    The previous owner thinks he has a new seat cover and throttle cable.

    Not sure what I'll do with the fenders. May try my hand at some plastic welding. Any suggestions from the masses?

    I would buy the fiberglass ones off of ebay here is the link http://www.ebay.com/itm/NEW-1982-198...a9b394&vxp=mtr. As for the tank see how the inside looks it might not be as bad as the outside and if it doesn't link and isn't too rusty have that tank painted as the plastic tanks for these bike is incredibly ugly.

    Thanks for all the suggestions. I believe I'll invest in a plastic welder. I have a 185s also that needs some plastic work also. I've got an air stapler I use for woodworking. I'll give that a shot on the seat cover.

    I hope the tank is salvageable. My 185 tank was in pretty bad shape. I wire feed welded all the holes up. Slow process chasing the holes, grinding down, leak testing, then chasing holes again. Finally got it sealed though.

    Supposed to pick it up in about an hour. Will know a lot more then.

    You called it. Front forks are frozen. Gas tank has a lot of rust inside. Ive got an electrolysis tank, so I'll dunk it this weekend and hope I have a tank left when it's done.

    Did get a seat cover with it and a new throttle cable.

    Pretty excited about this one. Brings back a lot of memories from Chistmas 1984.

    I've been looking online for some replacement forks. I'm leaning towards the 200m. Quick question though. I should be able to weld the existing forks where they are and prevent the scenario you descibed. It would allow me to ride it without the possibility of the forks compressing. At least until I was able to do the swap.

    Update on the progress. The gas tank has some rust holes in the typical locations. I used my wire feed to weld the larger holes up. Then mixed up an acid wash for the rust in the tank. It cleaned up pretty good. Good enough to pour a tank liner in. Pulled the tank off my 185 to use for the time being.

    Gave the carb a good cleaning, changed the oil, and installed a new battery. Neutral light came on, but wouldn't turn over. Checked the wiring and the starter wire was disconnected. Hooked it up and the starter started spinning. I guess the switch circuit will need some work.

    Pulled choke and touched the starter wire to battery and it fired right up.

    But...it smokes like a freight train. Blowing oil out the tailpipe. I'm figuring stuck ring. No real history on the machine, so not sure how it was running when it was garaged two years ago.

    So, should I spend some time with marvel mystery oil, or just pull the head and start the rebuild?

    Well, I tried the steam cleaning method. Didn't work too well. I'm sure it cleaned the compression rings, but didn't make it to the oil rings. The engine runs good, starts easy, and has good power. Just fumigates everything.

    I poured some ATF into the cylinder and will let it set for a day or two. If that doesn't work I'll try the chemtool treatment.

    In the meantime I'll start sourcing some other things that I need. Starter relay, tank liner, and bearings.

    I hope it doesn't come to that, but if it does I should have a solid machine that will last another 20 or so.

    I inspected the front forks a little closer yesterday and they are in pretty bad shape. It's going to take a little truing up to get the tubes centered so I can weld them.

    I noticed when I was riding it yesterday, it was really difficult to turn left. The rear tires are mismatched. I have a scorpion on one side and a Carlyle stryker I believe on the other once I get the rings sorted out I'll need to address that also. Would it be best to move the stryker to the front and put the on the back with the scorpion, or move the scorpion to the front and get another stryker for the rear?

    She's still smoking. I've tried all the tricks and haven't made any progress. Looks like a rebuild is in order. Will more than likely have it bored, put new piston and rings in, and rework the heads

    While I have the engine out, is there anything else you guys recommend doing? I'm planning on cleaning everything up and laying some fresh paint down on the frame.

    I pulled the motor this morning. Except for a few broken bolts while removing the plastics everything came apart pretty easy.

    The bore didn't look as bad as I thought it would. The piston had quite a bit of play in all directions in the bore.

    I've got a local motorcycle shop that will bore the cylinder for $40.00. Depending on cost I may have them do the valve job also. It will be interesting what the bore measurement is.

    I'll upload some pics later.

    If you can not do the valves yourself I would defiantly have them just take them apart and clean up where the valve seals again the head. And also change the valve seals out. It would be horrible if you had to pull the motor again because the valves are sticking or generally not working. Now as for the cylinder I would ask the shop to only to the minimum I would not bore out the cylinder if it only needs a hone The closer you can stay to the stock bore size is best big bore on a utility 4 stroke is not only unnecessary it probably does more harm than good. Sound more like someone put the wrong size piston in the bike to me.
