    My buds 13 350xcf didn't. I refused to do anything until it had proper fuel pressure.

    The head isn't the issue. The cylinder on the 95 model is roughly 1/4" taller than all other years so the wrist pin location in relation to the crown is farther down towards the skirt. The head has a smaller combustion chamber for use with the flat top piston. Our head is fine, but finding a good usable 95 cylinder has turned into a no win situation. Previous years, and following years, are shorter cylinder, with dome type piston and matching head design. We would need the entire setup (head/jug/piston). The cases, crank, rod, powervalve assembly, and exhaust location are the same for previous and following years. KTM just did some weird crap in 95 and its pita to find parts. In 96 KTM added coolant ports on the PV retainer as they were having a lot of issues with cylinders failing on the bridges between the powervalve flap and the smaller rotating valve. its a very thin area and cracks very easy once the piston expands too much from excessive heat. The addition of extra cooling ports fixed the problem. However, those cylinders are also 1/4 shorter than 95. In short, 95 is a bastard year. To add fuel to the fire on this, the jug was perfect along with the piston, but a bolt getting lodged into the waterpump feed hose while it was all "boxed up" (bike came to me in pieces) caused an overheat situation and as soon as it got on the pipe it nuked itself. We just put new main bearings and seals in it as it was smoking like crazy and the right side crank bearing was wasted.

    Cant be 180 out, only has one key and there is only one lug on the flywheel to pass the hall effect sensor for CDI timing map. These bikes are super picky about fuel pressure. Hook up a fuel pressure gauge at the quick disconnect between tank and injector. Roll the motor over. Should build 50psi and then drop to roughly 48psi and HOLD. If it doesn't hold, then either the pump check valve is not seating, or the injector pintle has trash in it. If you cant get 50psi period...put a pump in it and not one of the cheap aftermarket ones.

    Ok a bud of mine asked me to post here since he does not have an account and I work on his bikes pretty regularly. Looking for a 95 250 sx cylinder and piston. I know 95 was a one year only flat top design and the cylinder is taller than all other years. Its kind of an oddball. At this point, would be willing to go to a 96-98 setup as well. If anyone has a lead on one thats not completely decimated, let me know. I found a few older ones on fleabay that needed recoated by the bike isnt worth the money so "usable" used parts would be fine.

    2014 KTM 300xc keeps blowing crank seal

    If the seal doesnt pop out, then the next thing I would have inspected would have been the bearings. These seals are pretty durable.

    Removing the cover from the starter?

    I'd bet the starter maintenance video since the cover has to come off so often to keep the magic button working in most of these. the PO of my bike, drilled a hole in the grommet by the stator harness and installed a the plastic fuel tank vent hose elbow that normally screws into the steering head. A hose is routed up to the regulator area. The small "weep" area is sealed off and the entire cover has yamabond on it to seal it to the case. So far so good. I just pull the crown wheel cover once in a blue moon and put some amsoil heavy waterproof grease on the gears. Seems to be working.

    Hmm, thats actually not a bad idea. Seems less heat would be held on the cover as well.

    why doesnt the bottom of my air filter seal???

    jebus...increasing the surface area in a given area does not not equate to increasing the filtration surface area. Get a uni/no toil and call it a day.

    Well hope the cylinder doesnt need recoated.

    Ouch...yeah thats low. My sons 03 50sx has 176# after 4 kicks WOT.

    Ok, logging into my account at home was a total mffer....sigh The plastic cage has a single more "rounded" corner. It MUST line up with the same mirror corner of the boot. It will look like it fits a few different ways, but there is only ONE really gradual rounded corner on the boot. Also, you can tell by the angle of the filter once its installed. The peg on the spring should fit in easy to the grommet with no binding and the filter should almost be "semi" flat looking on the side that faces the left side cover. Since the p/n matches, it "should" work. Its kinda hard to explain how the cage fits in and since you have the filter out, you should play around with trying to "flex" it in where the flat extended side parts snap into the boot. I jacked around with mine for a good while till I finally took the filter off the cage and found the orientation of the cage to the boot. On the cylinder pics, without measuring the bore, all bets are off. However, some of the lighter areas up around the part where the rings stop, look very "light" like its wore through the nikasil.

    The cage has to be "folded" together like a taco a tiny bit during install (lack of a better word) to get it to go into the boot. The plastic "ears"(top left and bottom right on your second to last picture) or raised lip snaps into the boot. When putting the filter/cage on, put the backside in first, and then bend the cage a small amount to get the outward facing part to snap inside the boot lip. If you dont, it will hold the bottom of the filter out away from the boot and you end up with the problem your having.

    I believe OP was referring to the plastic cover, not the stator cover.
