Some body explain the grooved piston/grooved rings thing to me. I don't know what you guys are talking about and I am probably going to have to put a top end in my T500.

If you go with Plasticote Engine Enamel in a Spray can it resists gas Very well.It takes a little heat o Cure it so I just stuck all of my parts in an Old Car in the sun during the Spring with the windows rolled up.

One of my other "hobbies" is building model airplanes. They get exposed to raw fuel and burned residue. The nitromethane in the fuel is a powerful solvent that will eat some finishes.

I find that I can use almost any type of paint for the color and then shoot a coat of automotive clear coat on top. The two part catalyzed type made by people like PPG, House of Color etc. This stuff is the same as what's on todays cars and it will withstand gasoline splashes.

You can either do it yourself or contact a local autobody shop. They shoot clear all the time and it isn't too expensive to shoot your colored parts when they finish a paint job for a customer.

I will try to post pictures in a few days of the different pistons. Dofin

got pics hop this will print if not youll have to email me. gyrocfi at yahoo.com. bummer cant post here try the next one.

Better yet here is a post on ebay. Note the pistons on the close up pics!! one is smooth and the other is grooved. I dont think you want two different type pistons in your engine AND the rings are different as well. Smooth pistons have thinner smooth rings while grooved pistons have thicker rings with a single groove in the outside center of the ring.!! From what I have been told it doesnt matter to much which pistons you use as long as you them in pairs.

That is the first time I have ever seen a piston made like that. I suppose the grooves are supposed to help lubricate the skirt?? If it works, I wonder why it is not a common practice.

who knows but seems like the grooves were good ideas but most likely turned out to expensive to make and probably not as improtant with the new oils? Im just happy that I set in extra sets of rings for my groved pistons. !!

The grooves were intended for oil control from what I've read. As an assembly, the pistons/rings are interchangable, but you may need thrust washers on the wrist pin depending on the bike/piston combo. I think Lane has all the info on that set of circumstances.

I wouldn't mix piston types on the same motor as the transfer cutouts are different on the various piston types.

Anyone have a good supplier for aftermarket sprockets (front and rear) for a '73 TS250? The factory OEM ones are kinda pricey...

I checked the piston diameter and the clearance in the bores on my TS250, and it looks like I'm going to need new pistons/rings and a fresh bore. The parts fiche references part number 12103-30850-100 as "PISTON,SET OS,1". What does "set" mean...anyone know if this includes rings?

Thanks!

See attached pics of my '73 and '74 TS250 cylinders. (yeah, I know they need to be cleaned, I'll get to that...)

Is there any significance to the S-1 and S-2 cast into the side of the cylinders (just under the bottom fin?)

The "S-2" seems to be of superior design with the thicker webs between the fins???

Nope that will only be a Bare Piston.

I just checked my 66 X6 project. No lugs. - Which makes sense since they didn't make a scrambler until 67

Hi.

Well, I am looking now to restore those rear shocks on my X6 and I don't actually see any way to do it.

I mean, how could you ever buff out those springs and such if you can't take the shocks apart?

I was going to send them off to be replated, but I don't see how that could be done either.

Can it be done, or is there a different shock still made that looks the same?

Post by **Admin** » Wed Feb 21, 2007 7:43 pm

I'm sure it can be done but with any Plating Job it will be Expensive.I'm sure thereare plenty of other Brands out there that will look pretty close.I know that Redwing Made a Set of Totally Chrome Shocks that looked Close to the old stuff.I think Progressive may make a set of Chrome ones.
If you will look on Ebay now Canamdave has a set for the t500's for sale that are going for around $50.They may be bigger than what you are needing though.Take some Measurements if you can and Post them here and I'll see what I can dig up.
