Getting pretty irritated.....

[JustynCRX]

Okay here's the questions....

1. Does the warranty cover this? Doesn't hurt to ask.

2.The cyclinder, is it okay? And if so since malossi doesn't let me buy individual parts from the kit, could I just get a polini 47mm piston?

3. I'm going to disable the oil pump and premix from now on. What ratio should I use once this thing is back together?

4. Can I just remove the shaft from the pump and bolt it back in?

If there are no scratchs on the bore that you can catch your fingernail on you may be able to lightly hone the melted aluminum off the walls and clean up the sharp edges on the ports after the hone. It is definately possible lack of oil caused this damage since it is all the way around as far as I can tell. Baka-san will be able to tell you exactly I am sure he is pretty kewl like that.

With that piston the bore is going to be screwed. You either have to over bore and use an oversized piston or buy a Big Bore Kit (BBK).

I'm thinking I might have to get a whole new kit. Which kinda sucks. Now I gotta find something to do with all the extra reed valves I have because none of them fit my stock intake. Not that I'm even going to use the stock setup since I have a CT setup coming.

d***, that sucks. Anything in your current kit good, that you could sell to recoup?

Well my carb is BRAND NEW, like only a couple hours on it. The old carb is still good its just filthy. I have both sets of reeds. the two petal reeds are set in a 2 bolt cage for a spree so I could sell that for a couple bucks, I still have the three petal reeds. Also have an extra spree engine case with gears. Double throttle cable will be for sale since I cant use it on the OKO. Unfortunately its 73" long and I have to find an OKO cable that long. The longest I've found is 60".

As suggested in PM, I'm going to write down my plans and get some approval from the masses.

Buying a new bbk.
Using my malossi head. (Installed correctly)
CT intake, 21mm oko, foam pod filter.
Disabling the oil pump and going premix. (Don't know ratio yet)
I'll be using the jet sizes recommended by Baka.
And bpr8hs plugs.

Opinions?

Greetings:

That sounds like a good plan with the possible exception of the Malossi head.
The diameter of your unspecified new kit has to match the head's - 47mm?
Port timing and head volume both affect dynamic compression. Slapping the Malossi head onto another brand may or may not yield best outcomes. Some kits come with a cylinder head. If yours does, I'd use that one.

Malossi mhr bbk sorry I left that out.

yeah that bore will need a at least a 1mm over bore on it by the looks of the scratches. order yourself a oil plug or just grind the gears down and put everything back in.its so you dont take away crank case pressure. you will only be able to use the malossi head on a bore of the same size. premix to 32to1

Best place to get an oil plug?

Update:

Engine has been removed, ripped apart, and awaiting parts. I went back to 9g and 10g weights, put a brand new polini belt on, new brakes, and cleaned everything up a little. I did a little reading and had a question. Should I double my head gasket during break in? Since I will be getting another BBK this weekend. (the same one) I will have 2 head gaskets kicking around. Also since I am doing premix and dont want to use the oil pump, can I loop it back on itself until I can get a plug ordered? I used to do it with my cars when I removed my heater core. (in Maine? yes) and in theory I'm thinking it should still work for this. I would have to get a reducer of course.

the malossi cast for the se50 is not that high of a compression ratio so 1 head gasket is good. just grind the gears down on the pump and put it back it.just make sure you either take the oil tank out and empty it or drain it. that way you leak oil by accident all over the place. since your using the stock unrestriced exhaust you should have just stuck with the stock carb and manifold setup and just got a stock airbox. trying to tune a aftermarket carb with your experience with 2 strokes is going to be even more of a headache than you know. look how easy it was to fry a bbk with a stock carb with the wrong jets, oil ratio and no airbox. now you have to adjust and tune 4 areas of the carb plus the trans together with the engine.
