    Good looking sled as is. Should help restoration to have a straight and complete start

    Hello cloughrin. To clarify about blasting the engine. I abrasive water blast my engines with fine sand or crushed glass to remove all dirt and grime buildup. I then water blast with glass beads to smooth out the aluminum surface and creates a satin shine. I do not tear the engine apart to do this unless I am doing a tear down anyway. But then one must make covers for the intakes and exhaust ports and seal off any other openings and protect the PTO shaft and seal. I make simple 20 gage steel or aluminum covers and use silicone gasket maker for 100 % sealing and this works perfect. The blasting media will get in anywhere that you do not 100% seal up real good. See my restore project 75 440 Sno Twister.

    Thank you for the replies. That motor looks great. Now I just have to find someone with a set up to help me out with this.

    A few more pics as I got it to the front of the shed. Hoping to get it into the shop this weekend. Pictures make it look better than what it is. The lighting is not great but I had belly pan redone when I first got it along with the seat. Belly pan was spray bombed with Polaris midnight blue paint. ( Will probably regret that).Not decided how far I am going to go with this thing yet....

    Looks like a nice shape original as it is! Your plastics pieces (dash, tank, trunk lid, etc) are not faded or broken looking so thats a HUGE bonus and a good start to a resto! Looking forward to seeing more.  8)

    Thank you. Trunk lid is excellent. Tank and dash are faded and need some work hard to tell in pictures. I got the sled moved to the shop last night so hopefully take some pictures in good light and start with a basic cleaning and put a plan together from there.

    Anyone have suggestions for rebuilding the master brake cylinder? I noticed it is very soft and low on fluid. Is there a seal kit for these available? I have never had one apart before.  Thanks

    I don't what level of restoration you are doing, all correct or just a rider. The newer style master cylinder from the mid 90s makes things easier as you can remove it from the handle bar quickly. Parts are available from many sources.

    Not a professional restore by any means... But Iwould like to rebuild the existing brake cylinder if at all possible.

    Nice TX 250, I have bought rebuild kits from the Polaris dealer that worked, they were for a late 80's early 90's ATV's.  Have them show you the diagram and look for the same looking brake cylinder and it should be good.  Basically all you need is the cup and O ring anyway. Also I use Dot 5 silicone brake fluid in mine, if you spill some it will not eat the paint and it does not attract moisture. Don't mix the two types, flush the Dot 3 out and refill with Dot 5.

    Drift Buster: I will look into that this weekend. Thanks. Does anyone know what the center to center measurement should be from primary to secondary. Or crankshaft to jackshaft?

    Thanks ACRNEON. I did download and print everything I thought I needed. Must have missed that.

    Long story short this is what I came up with tonight as I started taking things apart. Engine number and model number. The way I read this the chassis is for a 250 and the motor is a 340? What would you guys do.. Change decals to match the engine? Find a 250?
