ok I dont meen to sound like a moronr but the 350X was NOT liquid cooled right? It just had the oil cooler radiator? Im dieing to get one, as im more of a 4 stroke kinda guy no doubt. In equal conditions would a Tecate be a equal trade for a 350X??? I offered my Tecate to one guy for a 350X but he turned me down.

this isnt really a ATC question but a 2 stroke question. Im about to rebuild this RM 125 to trade this guy for something with more wheels.. So its a topend rebuild (piston & rings) and someone told me that i needed to hone the cylinders. Ive never done this before, is it really neccisary? thanks

Yeah the X is oil cooled. As far as the trade, if you have the T3 and want an X and y'all agree on a trade, that would sound fair to me. I have made a couple trades that others thought were silly, but I traded for what I wanted and was very happy with it.

Yes, you need to hone the cylinder. It's super easy, I just use a brake cylinder honing attachment (maybe $10) on my drill. Run it up and down the cylinder and it does fine. Very easy.

ok, how long should i run the honer in the cylinder? This is suppose to help seal the new rings right... thanks

Till the cylinder takes on that cross-hatched look. Usually just a few tiimes.

what you are basically doing is breaking the glaze off the cylinder wall to give the piston/rings a better seal

Before you hone - you'll need to measure the cylinder to see if it needs honed only - or if it is egg shaped you'll need it bored - then honed. If you need it bored - you will need to order and oversized piston - then take the cylinder and new piston to any local engine repair shop for the bore to match the new piston. If you just hone and put a new piston and rings in - you may have problems depending on the existing cylinder condition.

I find it is best to have a professional look over the situation first - a dependable honest professional that is..............
