I would love to buy a new vapor recovery canister but I can't find one on line and my parts diagrams show only a thing called a one way valve with a hose going to a canister looking thing but no part # for the canister.

I thought of putting a balloon over the canister vent just before I pull it in the garage. If that stops the stink, I'll know the canister is bad.
Just in case, can I change the line from the tank to the canister that you mention without draining the tank? Or will I have gas all over the place?

Ever since I got my JCL MP250A there is a strong gasoline smell when I pull into the garage after a ride. The next morning, it's gone. I have checked thoroughly for leaks and there are none. I'm wondering if the problem could be the charcoal canister. These bikes are 2007 models which were gassed up and tested when they were made. They have been sitting around in crates for four years. I'm thinking the charcoal canister may have gotten a snoot full of gas and crapped out in the crate. Have you ever tried to find a charcoal canister for your scooter on line? Good luck!  Ernie |

Only problem is it always stunk like gas when I pulled it in the garage after a ride. Now it is really strong. My wife is making me crazy over the smell.
Any ideas or is this just the way they are?

I just took it out for its maiden voyage after the new tune up and WOWEEE!!!!! It has twice the power as before and it even seems quieter. Now if I can just figger out where these two 1.5" black sheet metal screws and this 1" by 5mm black machine bolt go, I'll be as pleased as a pig in poop. They must go somewhere in the rear half of the scooter since all I had off was the seat, seat pan/motor cover, top case and the big plastic wrap around. The sheet metal screws don't bother me too much but I worry about a 5mm diameter machine bolt missing. I hope my butt doesn't fall off someday on the road.  Ernie |

If we're changing oil every 500-1,000 miles, I doubt if it's really an issue. I put Castrol 10W-40 in mine and next time maybe Valvoline or Shell.  Ernie |

Well, it's done! I found the perfect little wrench for that nasty bolt on the exhaust valve cover. I don't know it's name but its an open end on one side and a tiny 8mm ratchet on the other side.
Valves adjusted. Mixture set. When I crack the throttle it wants to fly.
Funny thing happened though...after I adjusted the intake valve the first time, it ran sort of ok then it got sluggish. I came find that the locking bolt on the tappet unscrewed itself and fell down into the exhaust valve cover. It still ran. What a forgiving little motor.
Who knows, maybe the Chinese will learn quality control some day and they'll have a decent product.
BTW, the exhaust valve was tighter than a $3 whore.

I finally got that nasty bolt out of the exhaust valve cover but now I can't seem to see the arrow in the peep hole when the line points to it's mark. I've turned the motor maybe 25 turns and still can't see the arrow.
HAAAAAAAAAAAAAAALP!!!!!!!!!!!

I tried laying on the floor and using a wrench. I couldn't get a grip on that little devil for love nor money.
I guess I will drop the bottom and try again. Maybe a 1/4" drive socket with a short extension will work.
Do those TDC marks have to be perfectly aligned?
Thanks for your help JR.

I set the mixture to 2.5 turns out. I let it warm up and it was stumbling all over the place and wanted to stall. I increased the idle to 2k. After warmed up, I gave a quick full twist on the throttle and it was straining to pick up rpms. Only thing I can figger is when I adjusted the valves(could only do the intake one-fuel tank in the way.) I must have made an error/ I had trouble getting the arrow exactly on the mark in the peep hole by the oil filler. I was off maybe 1mm.
I'm going to let it sit all night and tomorrow evening I will remove the valve cover and crank it around until I get maximum opening at the valve tappet and reset it to .004. Since I'm not doing the exhaust valve, it shouldn't matter having to align both marks for TDC.
Correct me if I'm wrong. Any other suggestions would be appreciated.

I took the plastic off the back and I have the carb on my MP250A upside down. On the front end of the bottom closest to the engine manifold, there is a long brass screw which was turned out 4.5 turns. Behind this toward the center direction is a small 3mm circle which could be a plug. What are both of these things and what should I do with them?
Also, I have a slight fuel leak which appears to be between where the bottom fuel line connects to the carb. I snipped a piece off the line and plugged it back in. Is this enough with the little rabbit ear clamps the use or should I get a screw type hose clamp?
Thanks
Ernie

I want to remove the big plastic dash panel on my JCL MP250A. This is the panel that surrounds the steering shaft and has the glove compartment in it.
Can anyone tell me the secret for removing it? I tried once but it would not move very far, even after removing the large bolt inside the glove box.
I am hoping to mount a small motorcycle radio in the recessed circle on the left side. I want to use the existing speakers. The only other thing is I need to find a switched +12v and +12v going directly to the battery. I hear reverse polarity can cook one of these little radios.
Thanks in advance.

hope you have better luck at the shop then i did Please tell me you didn't take yours to Hy Pro Motor Sports? To clarify, I meant I hope I don't have to wait a long time to get it back and they fix it right. They seem like nice folks but I've not dealt with them before. Ernie |

Thank you very much. Is there anyone on here that is specifically familiar with the JCL MP250A?
