I need 225dx help

[muthey]

no it is a little smaller on the sleeve, you can bolt it down and everything but I have a feeling if you run it it will seep oil from the bottom just because of the space around the cylinder and the base. I have a 225 cylinder and and head I will sell you for a decent price, also have the piston as well never been bored

[mike11743]

awesome. How much do you want for it?

[mike11743]

anyone know where to find the part number for the piston to see what size overboer if any it is. All I can find is 29u00 stamped on the inside of the front of the piston.

[leevarnado]

your prob gonna have to measure the piston with a set of calipers.

29U-11631-00-Y0 PISTON STD 70mm
29U-11636-00-00 PISTON 2 O/S 70.50mm
29U-11638-00-00 PISTON 4 O/S 71mm

[mike11743]

i'm coming up with just under 70.00 everywhere on the cylinder and the piston is more like 69.7 but I assume thats stock bore.

[leevarnado]

mike,i have a new std bore wiseco 10:25.1 piston for $75 shipped.pm if your interested.

So I got this thing all back together with a new piston and used head assembly and Still can not get it to start. Getting good spark and I have fresh gas and along with that I cleaned the whole fuel system. Has good compression also, I cant get my compression checker into the plug hole because I dont have the right adapter but I can drift it down a pretty steep hill and lock up the back wheels. I'm thinking my problem might be with the timing. I timed it according to the process in the owners manual. The only part I got somewhat confused on is all the timing marks on the flywheel. I have a line with "F" ontop, about half an inch from it is a "t" and exactly 180 deg. from that one is another "t" There also is another line with no lettering on it. I lined up the "T" clostest to the "F" and spun the motor over by hand and everything cleared. Do I have the right marks lined up??

[muthey]

It should be lined up with the t by the f, but I wonder if it is the stator, on the original that I have 180deg from the t is a rectangular plate that sticks up, so I wonder why you have another t. I will take some pics for you so you can see what I am talking about.

[muthey]

If yours doesn't look like these something is different about it and maybe try the other t, and see what happens, but be very careful I would hate to see it bed a valve

[mike11743]

well it turns out that my stator has 2 f's with t's next to it. I tried both, and both are at top dead center. I assume one is on the exhaust stroke and one is on the intake stroke. I'm not really that familiar with 4 strokes. Niether of them lined up will fire though. Has to be something with timing or compression though becasue im getting good spark and good fuel.
