Finished stripped off the plastics off today , borrowed a trailor and took the scoot to a friends house to do the major work on the scoot. His son took on the job which was a relief for me cause I am returning work after being off for 3 weeks with a kidney stone.
When we unloaded the scoot , I told him about tbe piston size, He said ," look here" . Stamped on the head were tbe #s 170 , Is this the piston size ?

As I started stripping down the scoot today I found a tag and here is what it had on it. Engine Displacement : 244.3 cc Engine Family 8GLDCO.25NFG Is this something I need when I order parts ? It also said to use 90 octane or higher. Engine oil sae 10w-40 type SE Spark plug: CTS-C7SHA Gap: O.7MM . Can someone translate the O .7MM over to Thousands for me ? LOL'S I don't know if my guage has metric on them or not.

Thanks for the help guys. I'll keep you posted as I get time to break it down to see what kind of damage has been done. Still, I'm wondering what has been the cause of such damage.

Thanks for the scrappydog site. I think it looks like the best for me. This is all new for me so I think I'll take some pictures as I go for reference for putting it back together. I know it's easy to cross the vacumm lines and where to hook up the gas lines on the carb.

Thanks J. R. Didn't know that there were 3 different sizes. The break down will be 1st.
Cruiser I have the horizontal engine not the vertical. A friend has the vertical Mc-13 Bali.
Hey Guys, check out scrappydog and let me know what you think. Are these parts for my scoot ? I can even get the head and the valves here.

Can't thank you enough tvnacman, you may have saved the day. Going to make a call Monday morning to see if they have the parts. If they do I think i'll order them and get them on the way. I may need lot of guidence to get this scoot back in order but 1st. I need to know what caused this . I really don't want to shell out $$$$$$ every 10,000 miles. Not worth the money and time. Afriend of mine said that I could get a big bore upgrade that would make it a 300 cc , huuuuuum ! Now that's worth thinking about ......

Well don't feel to bad, my wife thinks I'm going to get killed out there with semis on the inter state. So she says " Why don't you just junk it and forget riding a scooter". My answer " Not on you life, I like my scoot and I'm riding ".
Now I'm not much of a mechanic but I take it one step at a time. Plastics on a 250-B has a lot of screws, bolts, and clips. I take off one piece at a time and use pill bottles to put them in and then tape the bottle to the parts they came from. This helps a lot. As far as getting parts to fix yours, what did you end up getting?

Yep tvnacman, that's the plug. And I can imagine that is what I'm going to see when I look at the piston but you beat me to it. Can you tell me what was the cause of such damage ? I startred to take out the spark plug with the cheep wrench that came with the scooter but I ended up using a socket and ratchet and still had a tough time getting it out. When I got the plug out, the end of the threads had a lot of aluminum shavings on it.  |

Yesterday I was comming home from a friends house on the scoot . About 3 miles from home I hears a loud " POP " and some loose change rattleing in the motor. Looking in the mirror I see lots of smoke. The engine dies out all together as I'm pulling off the highway. Tried to start the scoot and the motor spun like there was no tomorrow. No Compression. Called another friend and he came and saved me with a trailor. This morning I took the plastics off so I could find the problem. Took off the valve covers and checked if the rocker arms would move. They did with no problem. Next I took out the spark plug and Wow, the end of the plug was completly distroyed. Checked it for compression, None at all. I'm thinking that the piston is shot. Next Question is , I'm thinking that I'm going to get a new motor for a MC-250-B and replace the old motor with a new and then fix the old motor for a backup. Where can I get a new motor ? Might be down for the rest of the year. |

Yes, the rubber bushing that hits the bottom of the motor. Bolt and bushing completely gone. Just wondering what size ? I ride a MC-250-B Just like the Professor.
Ever have a kidney stone attack while ridding a scoot ? Not fun !!!!! And hurts like HELL !

Got home the other night and getting off my scoot I noticed a loud rattle. looking for the problem, I thought I would put the scoot on the center stand to check it out. I found out that it was the bushing and the nut and bolt were completly gone from the center stand. Oh ! 250-B and red Please help with the part # for both of these. Just trying to pass a stone . First one Scooterran |
