I have an 85 Maxim XJ700 w/19k & just got it out of the shop 2 weeks ago to have the carbs rebuilt @ $90/ x 4hrs. She is STILL one cold blooded machine until its been rode for about 5 miles, after that she runs like no bodys business. Would doing these procedures help with this cold bloodiness? Also for what's worth I have a YT video that show how well she runs for a 25 year old bike :)
The procedures will prevent you from having to pay for another carb clean, but will not take out the cold blooded condition. The carbs are setup lean to meet EPA emission standards. A jet kit, if available for your model, will take most if not all of the cold bloodiness out. Be careful though, as your bike will no longer meet emissions and may be illegal for highway use in your state...
I may be in California now and also one of the stringist states as far as EPA goes but I'm yet to see motorcycles showing up at the smog test stations....yet. Thanks for the tip.
On this video, a Canon SD780IS. Other cameras I use are Kodak Zi8, Kodak Zx3, Canon S5-IS, Canon SX10-IS and Canon G11. I use the Canon SD780IS and Kodak Zx3 the most...
This 07 Yamaha with 1,100 miles in over 3 years means it has done a lot of sitting with fuel in the carbs.
Yes, this was caused by faze separation. Ethanol has an affinity for water; this means water in the air will be drawn into the fuel. This accelerates the fuels degradation and decreases combustibility. Combined with the alkaline reactivity of ethanol, the fuel system components can suffer. It robs fuel of BTU's (3% less power at 10% ethanol).
Ethanol is not aside and shouldn't eat any thing that new. It is possible that their was faze separation if the fuel got exposed to oxygen by leaving the cap of of the fuel or something. Ethanol alone should not have done that, i run a 50 percent blend in my car and 30 percent blend in jetski. neither of them are flex fuel. I think ethanol is a grate fuel and i hope you don't give up using it.
When the pump says that it may contain up to 10% ethanol, it may legally contain up to 20% by law. Its very moist up here in the Northwest and this has been a huge, huge problem for carbureted motorcycles! I've been doing this for over 30 years and never seen so many carb issues until all our fuels up here started containing at least 10% ethanol over the past three years.
that suck that you are having issues with Ethanol. I have never came across that with my equipment, but i have fuel injection instead of carbureted maybe that makes a difference. Hope you have better luck in the future.
We have not had any issues with the fuel in the fuel injected models (other than the loss of power - that only a dyno would notice...). Thankfully, the majority of the new bikes are now fuel injected. However, there are a tremendous number of carbureted bikes still out and about and the fuel related problems are huge.

What kind of camera or video recorder do you use?
