    1985 250SX Resurrection

    I picked up a '85 250SX a few weeks back for basically $100. It had been sitting neglected for a few years in the back field. PO decided to put it on Craigslist with a little pull behind trailer so I nabbed the whole lot for $200. He said it had not ran in a year but with the condition everything was in and how disintegrated the front tire was I am willing to bet a few years. Either way the motor turned over with good compression so I took a gamble. I only got a bill of sale and until the title process was finished I wasn't putting one finger on it in case someone tried to claim ti during the process. Luckily though no one did and now its all mine with a clear title!

    I was not sure of the full condition of the motor so I did the bare minimal to see if it would run. Changed the oil and filter. cleaned the carb, put some deep creep in the top end to lube it up a bit and a new spark plug. I grabbed the battery from my XR650L and a quick prime and a second on the starter button and it fired right up! I even got a video of it starting for the first time in years.



    Well it fired up and ran so its all fair game now. First with the cleaning.

    This was the day it came home

    Cleaning the carb. Man this was some of the thickest turpentine Ive ever seen. Pull the slide up and it just sat there slowly sliming its way down.

    After the cleaning. I didn't put no new parts or gaskets in because I didn't want to put any money into this if it was shot.I got lucky as you can see in the video the carb held together and didn't leak.

    The initial cleaning was a ton of work, a couple cans of degreaser two brushes and a lot of elbow grease.

    Along with cleaning her up I also made a quick trip down to Tucson and scored a 1985 250SX motor with harness, controls, carb, exhaust, airbox and rear swing arm assembly with drive shaft for $150. The plan is to rebuild that motor down the road and then swap it out.

    Since the motor checked out with 160lbs compression I went on a shopping spree for this old girl.

    Carb rebuild kit
    UNI Filter
    New battery
    New Red Maier plastics
    New petcock
    New Clarke tank
    New seat foam
    New seat cover OEM style
    New PRM-ATV Grab bar
    OEM style sticker kit
    New10x5 ITP steel front wheel
    New 9x9 ITP steel rear wheels
    Duro Thrasher front Tire 23x7-10
    CST Ambush rear Tires 22x10-9
    Pro-Taper SE 7/8" ATV High Bend Silver bars
    New front brakes
    New steering stem bearing
    New front wheel bearings
    Fork seals and oil
    Some new grips
    and some small misc OEM replacement parts.

    Thinking about maybe taking the rear shock out and down to ZR1 Suspension and having him rebuild the shock and maybe install a heavier spring since I am viking sized anyways.

    Upnatm it's actually your build thread that I got most of my ideas from. All the way down to the HRC decals, I love those.

    So credit for the ideas of this forth coming build mainly goes to you.

    Nice score. The SX is my favorite trike. I've done ground up rebuilds on several. That's the one they will pry from my cold dead hands. My daily driver is the one with the white star. The others I've sold.

    If you need help on anything, give me a shout. You can always get me at jamesbaldwin99@gmail.com. I rebuild the ES/SX carbs and differentials. I have a tutorial on both here if you need information.

    Thanks man, it was a fun build. Actually, without the help from the folks here on this site, like Jim, it would have been a lot harder to finish. I sorta wish it wasn't done, and I was still working on it.
    It's been a while since there has been an sx build thread here, so I look forward to watching yours unfold.

    Nice write-ups! Picture are what make them possible. I did similar of on some chevy truck forums and they got pinned to the top they were so detailed.

    I'll be using some of your carb thread for sure this week and the diff thread when I attack the rear end. GOD I LOVE DETAILED WRITE-UPS!

    Does rubbing alcohol,really work? Does it break all the dirt and hardened gas down? Never thought of using that before.

    You go well above and beyond what I normally do for a carb cleaning and rebuild. Just curious what you charge for the carb service? Do you have a carb to ship out and I send you mine in than? If not whats turn around time?

    I use 99% Isopropyl alcohol (technical grade)for many things. For the carbs, It dries out any residual varnish, dirt, or whatever is on the carbs. It makes bead blasting the bodies and bowls go faster. My cleaning process is done in several steps but the final step is to shoot carb cleaner through all the holes in the carb. I prefer to soak the carbs in Heptane but that stuff is a little spendy. Alcohol works pretty good and it doesn't leave any residue behind. I also use alcohol to clean and degrease parts prior to powder coat. Isopropyl alcohol has many uses. I buy it by the gallon on Ebay.

    I charge 95.00 for my rebuild services. I have done dozens of the ES/SX/350X carbs so I've got pretty good at it. My turn around time is only a couple of days but most of the time I try to get them back in the mail the next day. Right now I'm out of ready to go carbs but I am more then happy to give yours the love it needs. I have plenty of spare parts if I need to replace anything. I do all my carbs the same way every time and it seems to work.

    Ok Ill have to see if I have that lying around. As you can see from my list I went on a spending spree plus the spare motor I just bought has kind of left me stripped of play money.
