Hi there sorry. In order to start this thread I thought I could attach a photo. I went through the Help section several times and did not see either a paper clip icon or any further notion of how to attach. I am using an ipad. So anyway I changed my oil yesterday on my 2008 Roketa 250.---BTW before I get to my issue the gentleman who posted the original valve adjustment tutorial has always been my hero since he is the reason I have turned 12,000 trouble free miles (except for stuff caused by local people I used to bring it to to repair). Anyway yesterday I changed the oil as I do every 1000 miles and in the bottom of the crankcase was a "fluted" engine part about a half inch long. I wish I could figure out how to show you my bike and the part. Obviously it came from "inside" the engine. I was installing a slip on muffler from parts for scooter and since I have always run the guzzi as I call it though I know its not a guzzi well into the winter now on these warm days we get in the Northeast. I wear a full crochrocket suit and fullface Core. Pretty comfortable. I have always done above 60 or more runs on our blue routes staying away from North Jersey. Anyway, i didnt mean to start a whole thread either. I havent been here in a while obviously since I adjusted the valves this bike has given me nothing but pure pleasure and a finger from Harley rider once...maybe it wasnt me ha-ha. Yea and hello to you too! Anyway anybody out there with a similar discovery or somebody. Please help! Thanks!  |

If it's not the oil-filter screen, it's possible that it's something that didn't belong in the engine to begin with: something accidentally deposited at the factory... It can happen... But for it to have been inside for years, then suddenly "emerge" without damaging the engine would be a major miracle. I DO hope that is the case with your engine!  Please DO try to get a picture posted so we can see what the part appears to be. You can save a jpeg into an on-line source like PhotoBucket and paste it into your thread that way.

![]() Hey thanks for the reply! Can I just say.....you dudes are the best! I mean the dudes like you who respond with just a chance to help somebody out. Hey in case you can't see it here in the in line URL. You should be able to the part and my guzzi. It ain't a Guzzi of course...but with my new pipes I get head turns! URL rrrocketa.shutterfly.com/pictures#:type=Pictures&title=undefinedYou should see the part I found. You photo shows the elements I am familiar with the screen, spring etc. but this bugger has got me totally flummoxed. What is it? I was thinking without ever having cracked open a block any block that it was in some machined insert for the pistons in the cylinder wall and just fell out...but that can't be.....it woulda torn something up! It had to be from somewhere "up" right? Jeeze I sure don't know. Like I said just noticed it when I changed the oil this time. BTW I meant what I said about you dudes especially that valve tutorial I guess was on SD...that deal solved every problem I had and this little scoot has given me nothing but the best rides since! Like I said she cranks up an hums after three ties like always, a little tougher now that its colder even though she's geerage kept. Anyway anything you can come up with is cool. Lemme thank the other dude too. |

Hey chopper guy! Please see my reply to the dude since he responded first...but you came up with what I think we may be dealing with. Now you and he may have by now seen my pictures of it. Thats my finger so i could give an idea of how big it is.
Again I just dumped the old oil into the pan and I was retrieving the stuff in the picture the other dude showed and there was that other part. I was looking at it just now trying to see if had evidence of being sheared off by force or scoring or any other damage and im saying there does not seem to be any. So if there is no sign of damage to the part and there's no damage to my engine than your theory seems right.
Only thing is that since I changed the oil there is an inordinate amount of blue smoke on ignition. I NEVER noticed that before. But its not like its oil getting into the piston chamber or anything believe me I had a Sunbeam Tiger with a blown main oil seal...I know what that is.
I figured maybe I dropped some oil on the muffler pipe and it was just burning off?
Im definitely stumped. So man thank you so much for reachin out. You dudes are awesome.

Yea that piece found in the crankcase, I checked the inside of a motor and there is nothing like that in the crankcase or the top end. I think that fell in there when they were slapping the motor together.
As far as the motor burning oil it is probably your rings.

Looks like a dowel pin to me, but from where?

tatsvamasi,
I'm with alleyoop... And he KNOWS about these things! I believe you just got away with something truly amazing... THAT part should have caused absolute havoc in your motor... But it demurely "pooped" itself out during an oil change. I think I'd like to have you buy me a lottery ticket... LOL!Sometimes you're the DOG, and sometimes, you're the TREE. THIS time, you were the (lucky) dog!  Ride safe, and enjoy!Leo in Texas PS: My "new" old Kymco has some major miles on her clock... I hope the boyz in Taiwan didn't drop any "surprises" in my motor back in the day... LOL!

It also looks a bit like the Oil seal on the Oil Pipe?  |

rrrocketa.shutterfly.com/pictures#:type=Pictures&title=undefinedhey. i put up a couple more pictures. That diagram of the fitting on the oil seal pipe in my mind looks just like it! But the fluted part I don't know the machinist term for it seems again according to the diagram to be "outside" the "inside" of the crankcase. Don't it? alleyoop and co. must be onto something since if in fact it was that oil seal it would blow out my pipes and never stop...you know the telltale cloud of blue smoke. Or it was happening all summer and I never saw the smoke and like alleyoop says the rings are going. I have to think in scooter years and miles since 12,000 on a scoot could compare to what 70 grand on a car? I guess im going to settle on something that was in there that was not supposed to be and when I jacked it up on the stand BEFORE I changed the oil it tumbled down...whatever it was....thinking that as unbelieveable as this sounds while it was running full throttle whatever it was COULDNT drop down. i dont want to go on and on but this bike whatever trouble it was has always and get this left me in walking distance of my house. The only time i had a tow was when I used to do tire changes at this place and I never imagined you wouldn torque down the rear axle nut. They didnt and I nearly lost a rear wheel at speed. That was the one time the scoot's karma failed tatsvamasi. So I gotta go with Lottery Winner...Today is a fine day before a week of winter and I will ride no doubt. I will post for everyone's benefit if something develops. Hope there ain't another shoe to drop if you get my drift!

tatsvamasi'
If the old gal's smokin' a bit, it doesn't necessarily mean the motor's all THAT worn. There's a lot of "wiggle-room" between "new" and "worn-out"... LOL!
There are a LOT of varied opinions on just what type of oil to use in these scoots. All have merit, but I'm of the old school when it comes to air-cooled bikes. Long ago, we used the heaviest oil appropriate for the season with good results, but it required changing oil every season with temperature changes. The old Harley Davidson "Heavy" oil (approx. straight SAE 70!) turned to "tar" at zero degrees... Yeah we were dumb enough to ride below zero in Chicago... LOL!
While modern multi-grade oils truly have fixed that problem, there are still a lot of differing thoughts on just WHAT to use. My Xingyue 150 "manual" called for 15W-40 Heavy-Duty Diesel oil. I always used that oil (Ford Motorcraft brand from Wal-Mart) with good results.
Now, my "new" old Kymco watercooled 250 service manual also specifies the same 15W-40... So, it seems Chinese AND Taiwan makers favor the heavy stuff. I agree. I know with these small engines, you don't want the oil TOO thick for the pumps, but with multiple factory-specifications for the Diesel stuff, and the multi-grade feature of the oil, there's no way the 15W-40 will be too heavy, even in winter.
The thicker-viscosity should also help some with minor oil-burning, AND with an older engine, I would not hesitate to add a SMALL proportion (no more than 2 oz) of one of the name-brand "No-Smoke" products like STP or Motor-Honey for a slightly higher viscosity. I've used those products in older cars and motorcycles with excellent results. Those additives bolster the viscosity and cling to rings, bearings, etc. without gumming up the oil.
Just my own experience... The scooter crowd seems to lean toward light-weight oil, while the motorcycle crowd leans toward heavy-weight oil. Since both Xingyue and Kymco specify the heavy-duty Deisel 15W-40 oils, I'll stick with them myself. And as a side-benefit, they may reduce oil-consumption too. Something to consider...
Stay safe, and buy a lottery ticket! LOL!

PS: If your scoot uses some oil, and you have to add some regularly, you benefit by the oil remaining "fresher" than normal between changes... See, even minor problems can be a good thing! Ain't life grand?
