Page 13 of the TT250 Owner's/Service Manual from CSC says:
"Use only non‐synthetic oils during the first 1000 miles of use. After that, you may wish to change to synthetic motorcycle oil." I will follow that. I recommend others do too, but that is their choice.

definetly never add slick 50 to any engine until its properly broken in.
ive never heard that about synthetics though. |

Azhulem I agree with your assertion that synthetic oil is generally not a problem, however my TT250 clutch made horrible noises and vibration when I put in synthetic oil. I have never had that problem with any other motorcycle using synthetic oil before.

take it from a 62 year old guy that has been riding almost daily since 1973...
Synthetics when they first came out had some issues, and caused some problems which gave them a bad rep. 1) They lacked the seal swell properties of mineral oils, and caused some motors to leak oil that were otherwise fine with mineral oil. The makers of synthetics learned from this and added seal swellers. End of issue. 2) Some old motors that had a ton of sludge from running mineral oil and lack of oil changes, they had that sludge loosened up by the new synthetics, and this caused issues as well, that were attributed to the synthetics, when in reality it was due to poor maintenance and sh*t mineral oils, and the pre-existing condition of the motor. Lesson, don't switch to synthetic if you have an old abused motor you are dealing with, unless you give it a good thrashing with clean mineral oil first.. 3rd item worth mentioning. Synthetics because they are so slippery, can cause issues during ring breakin. If the cylinders are not honed just so, the rings/cylinder interface can lack enough friction, and the rings can glaze and not bed in, causing lack of compression, oil burning, over heating etc. Manufacturers now hone cylinders with the proper grit hone and to the proper surface roughness so that rings will break in using synthetics. If you hone your own cylinder during a rebuild, or if you get your local billy bob machine shop to do the cylinder prep, you might want to use mineral oil during breakin. End of issue. Other things you can do, is to take care during breakin, do hard acceleration, together with throttle chops to seat the rings. If you end up with glazed rings, there is the old brit bike trick as a last resort, throw some bon-am-i (or comet) sink scrubbing powder down the spark plug hole (and start the motor) in an attempt to seat the rings. I would not do this however, I'd pull the cylinder and re-hone. Me when I'm building a motor, especially one with a nikasil cylinder coating, I use just one drop of oil on the piston skirt during assembly. Assembling dry (or near dry) is a good way to ensure the rings seat. Bottom line. If you use the sh*t chinese motor oil for a few hundred miles, and the rings seat, you will have no issue running synthetic. This is what I have done with mine. If you change the oil immediately on receiving your TT250, consider using mineral for the first interval, or if you use synthetic, pay attention to ring seating for the first 50 miles or so. |

I concur with mtiberio. Some of the early synths had their issues to straighten out, which they've done long ago.
The biggest difference between dino oil and synthetic (besides cost) is that the dino oil molecules are all different sizes. Picture a volley ball, next to a baseball, next to a soccer ball, next to a ping pong ball. This characteristic of the oil did help the damming effect in worn seals in worn motors. Synthetic oil has cloned molecules. They're all the same size ball. If these molecules were wheels, which wheels would you rather have under your skateboard? Bottom line is, run what you feel comfortable with. ALL oils are superior to what was offered back when I was in high school. If I have a choice, I usually run synth. If I don't have any at the time, I always have some dino 15W-40 in the shop. I'm not rigid on my choice and either will be fine.

definetly never add slick 50 to any engine EVER! That crap will make your rings stick to the pistons, lowering compression and cause it to burn oil.

I was just re-reading through your excellent thread in preparation of winter ending and Mod/Maintenance time beginning I would like to remove the SMOG stuff while I do the exhaust install as you did.. Just wondering what exactly you had to do aside from the block off plate.. was there anything else that needed to be fabbed? or just remove the canister and hoses?
Thanks!

Other than the block off plate for the head, there's a port to plug coming out from under the gas tank that used to go to the purge canister, and a port to plug off on the intake manifold. It's been a while but I think that's it.

I been looking within this thread, using it as a reference, and the pictures that went along with the posts are missing. Is it just me(viewing it through a mobile device) or are they no longer available?

I can't see pics either, and that's with a PC. Perhaps it's a Photobucket problem.
