Hi all,
I'm looking at carb options (large temp range here, and the bike's lean as hell at the moment) and the VM26 seems to be popular with the Hawk owners, I'm making an assumption that the fit is similar for the TT250? Anyway, there's clearly two different tiers available, the $80-100 dollar ones which I'm guessing are genuine Mikuni, and the $30-40 ones which are probably replicas. Are the cheaper ones worth getting? |

The cheapo ones will usually bolt right on the stock "intake" (before and after the carb)... some don't like these because of the "butterfly choke restriction"...
The more expensive ones that don't have the "butterfly choke restriction" won't bolt right up... you will have to either modify the stock "intake" system for it to work

Thanks, I ordered the cheaper version (it looks like only the cheaper one has the 48mm flange fit) and a set of jets.
My bike's been running really nicely, but the plug is pretty dry looking and when it's below zero out the bike's idling slightly faster once it's warm, I believe that's a good tell for a lean motor. |

I jetted them at either 115/30 or a 12.5/25....depending on aftermarket pipe and pod filter. Set the slide clip at the 4th notch down too. https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1

Not only that but we aren't discussing a Super Duke. We're playing with an Old World, pushrod, old tech motor that's built for longevity and torque for a very small displacement. That's part of the fun of being a China Rider. "What's the best results for dirt cheap?"

I commute about 15 miles, and as long as it's dry I'll try to use the bike. I can cope pretty well down to about 20F, below which my feet start hurting...

I have a stupid question: main jet kits for the cheapo carb are fairly easy to find, as they use exactly the same description on ebay as the carbs themselves, but I'm less sure about the pilot jets.
The reason I ask is that the OEM Mikuni fit at least for the main jet appears to be different - I've been using this page for reference: http://www.jetsrus.com/a_jets_by_car..._selection.htm |

My commute it 9 miles. My record low for a commute is 12*. If the roads are clear and there's no precip expected during the day, I'm out there. Heavy liner in the jacket, quilted over pants, heated gloves, balaclava and neck gaiter. My main issue isn't the cold, it's keeping the visor clear. It fogs up then freezes quickly if I don't crack it open periodically. My coworkers think I'm nuts (I don't necessarily disagree)!
Back on topic, I have the cheapie mikuni on the TT. I run the stock jetting at 100/20 but I'm also at ~6,000 feet. Rojo

You guys are brutal. I did the "rain, fog and freezing temps" much of my younger days. Now???? I do almost 170 a day, round trip. Anything below 65' and I'm in the Jeep.
The pilot jets from jets r us are listed here in multiple places, including my Rhino thread in the ATV section. Unfortunately, for some odd reason, China Riders is acting very weird on my daytime PC and I'm not able to search since later last week. Anyone else experiencing issues????
