I'm in the same boat as RedHawk, at 5,000 ft outside Denver and will be riding a lot at 8,500 to 12,000 ft. I'm sure I'll need to lean things out a bit. My first assumption is that the carb will be on the lean side to pass EPA testing and may be OK at 5,000 feet.
I did ask Ryan when I put the deposit down on the TT about carb jets. He indicated CSC would stock a number of jet options. I'm on the RX3 Baja ride and will be hoping to haul a TT back with the Orange Blossom Special. I'll ask about suggested jetting options when I'm at CSC. Rojo

Watch the plug. If it turns black at 5000 feet, the first step is to determine where in the range it is lean; idle, mid-range, WOT or all of the above. A plug chop in each range will tell the answer. Once you have the answer, you can jet and move the circlip accordingly.

CSC is not only doing a great service for it's customers, but also for all owners of CG engines! I'm going to print these all out and voila, my service manual for my trip!

The counterbalancer is gear driven. We thought about incorporating a chain drive for the counterbalancer, but Eagle Mike thought he might have a problem keeping up with new doohickey demand (you KLR guys will know what I'm talking about). The small chain drives the oil pump. I just added that tutorial this morning. Keep an eye on the CSC blog...Gerry just put the new larger-diameter front brake on my RX3, and I'll have a tutorial going up on front brake installation this weekend. I'm going to finish Moto Colombia this weekend, too. Lots of time on the keyboard these last couple of weeks. |

Joe B.,
I was just looking at the TT250 Clutch Replacement tutorial. I noticed the info on cleaning the Centrifugal Oil Cleaner: There's no mention in the turorial (http://californiascooterco.com/blog/?p=20111) of a service interval for cleaning this. Is it addressed in another turorial or in the service manual that comes with the TT250? Cleaning the oil slingers was a must-do maintenance task on the old BMW airheads and could lead to engine failure if neglected, so I am curious how often this needs to be done. It does look much easier to do on the TT250 than the old boxers though. Cheers, Dan K.

Dan:
That's a good question. I'll have a good answer (and an update to the tutorial) by the time the bikes arrive. There seems to be several opinions on this. One is that you don't ever need to clean it if you change the oil regularly and keep the strainer clean. Another is that you should clean it when you do a clutch replacement because you'll be in there anyway. And the third is that you should do it every 7500 miles, based on what Honda originally recommended for the CG125, which is kind of the grand-daddy for all of these engines (but guys who have played with those say they never found any contaminants in the centrifugal oil cleaner). We're talking to Zongshen about this now. And, of course, we'll keep an eye on this with our bikes, as we intend to rack up more than a few miles on them. I'm sure others will have inputs on this question. We're eager to hear from everyone. |

steering head bearing/wheel bearing replaced ,swing arm/linkage etc..changed the oil & cleaned the centrifugal filter... It was clean , next to nothing in it , this is a 03 model that had not had any maintaince done on it ever I would say...So can't imagine the filter had ever been cleaned before... PS... That Zongshen motor looks a bit better built inside than most other chinese bikes I have been inside of..... ..
