Hey guys,

Not sure if I posted this but about a year ago I pulled the trigger on a 1980 P125X that has a real nice (not perfect) body. I got it for $1200 and am very happy with it. It started right up when I was at the sellers house and also ran when I got it home. However, it was popping out of every gear. I have been extremely busy getting our winery building finished and the business open so it has sat for the last year slowly leaking two stroke oil. Now that I have the business open I have a bit of time and want to get back to this thing. My hope is to have it rideable by the time it warms up for some summer fun.

So...Before I dive in what do you think I am looking at to get it to stop jumping out of gear. And what will be involved getting the 2 stroke oil to stop leaking?


Cheers,

Alan

I haven't had to deal with this (yet), so no personal experience, but since no one else has stepped up, I'll give my 2 cents. The most likely cause of jumping out of gear is a worn shifter cross (aka cruciform). If you do a search here you will get lots of information.

How many miles are on your scoot? High mileage would tend to confirm a worn cruciform. Low mileage would tend to point toward something else. Replacing the cruciform requires splitting the cases. If you have high mileage, you probably should do a general refresh including new bearings and seals while you are in there.

Leaking 2T oil while parked is probably a crack in the oil tank or in the hose running from the tank to the carbureter.

Sorry I missed this. Welcome.

Good advice above, but a few things should be checked before splitting the cases.
First, make sure the cables (shifter and clutch) are adjusted out properly. Scoothelp has some good how-to's.

Also, make sure the selector box and it's components are in good shape. They do wear and I had this happen on a P with only 2500 miles or so on the clock. It's a much easier lift to check all that stuff before splitting the cases for the shift cross.

Can you locate the general area of the source of the leak ? Dripping of the bottom of the motor or mostly on the floor of the rear body ? Cracked oil sight 'glass' is not uncommon.

I have decided to pull the entire engine/transmission/clutch assembly and send it off to a pro to fix. I love tinkering and fixing my own stuff but I have a full time job and a new winery so I just don't have time. And I want to ride this thing in the spring. Once I pull the engine I'll dive in to the oil tank/hose leak.
