That's awesome. Hope you have many more K's!

Hi all,
I'm trying to replace my speedo cable, but I can't seem to get the front cover off. I have removed all visible screws, and it loosens, but does not come off. I've also noticed that I may have to remove the turn signal lights as well since the plastic completely surrounds them. Am I missing something simple? TIA!
Add some wd-40 too?
the kickstand doesnt retract to its original position, maybe something is broken? spring? it was working good for about 5 kicks then it stopped retracting) This being said, what can be wrong with it? broken bendix? it was working fine untill i opened it up to install the new parts.
Warranty does not cover towing. And most likely the dealer did not clean your carb. Tell them you want them to go through the entire carb and make sure it's not plugged up. Not much else it would be on a new bike.
Hi, all.
I've been doing research into fuel additives to improve fuel efficiency, and I ran across the genius of Sir Harry Ricardo. He gave us large parts of the technology that are used even today in modern high-compression engines. In 1921 he patented the Racing Discol 1 and Racing Discol 2 (RD1 and RD2) fuels. Apparently RD1 gave as much as 20% better fuel efficiency, and more power.
It was comprised of 80% ethanol, 10% acetone and 10% water. Apparently, to protect their IP and patent rights, they also added a bit of finely ground bone meal, which confounded chemical analysis, but made the exhaust stink to high heaven. Of course, that needn't be added.
Given that most fuel is 10% ethanol now, that 10% ethanol in regular gasoline can be converted into RD1.
This can be done by adding 47.32 ml of acetone and 47.32 ml of water to each gallon of regular E10 gas. Unless my math is off... please correct me if it is.
So for each fill-up of ~2.5 gallons for a typical scooter, something on the order of 118 ml of water and 118 ml of acetone would be added. A small amount of Lucas upper cylinder lubricant, to ensure fuel lubricity, would also probably be a good idea.
Apparently the complete miscibility of acetone in water and ethanol binds the water to the ethanol, and the ethanol to the gasoline, making a homogeneous mixture that doesn't separate out. The ethanol and acetone add to the octane rating of the pump fuel, while the water provides an expansion medium that far exceeds that of combusting fuel in air (water expands to steam at approximately a 1:1600 ratio, at the same pressure), adding to cylinder pressure.
Given that gasoline itself and the ethanol in the gas are solvents, the relatively mild solvent acetone shouldn't affect any o-rings, gaskets, etc. But it, along with the steam in-cylinder, should help to keep combustion deposits from forming in the cylinder.
What do you guys think? Has anyone tried this?
No prob, you get everything ok?
Bike is from 2011. It is 4T with roughly 7600km in the meter.
I took it out of the winter hibernation like a month before the oil change and it worked before and after the oil change albeit starting was getting tougher after it and then I noticed that the kick start was not getting the job done no more. Kick start used to be surest way to get the scoot going when temperatures were low.
About the variables;
I did put maybe a bit too much oil in the change and took out some oil after few days so that the level was at the middle of the oil stick and not little over the max level.
After the hibernation i did drive few days until I noticed that i needed to add some motor oil (2dl) and transmission oil.
There is indeed spark in the plug, though i am not sure if the spark is strong enough cos I can't compare it to anything. The plug is a Iridium one and cap is right. Carb gets gas so I did not yet clean the gas filter nor check the petcock. Filter is not transparent so I can't see if there is gas there. But I guess there is. Going to check/clean those next then.
I have also changed the air filter to a new one at the same time I changed oil.
The scoot is still starting from the electric starter. I have tuned few times the fuel/air mix and going to still do it more precisely soon.
Intake valve was roughly 0.05mm and exhaust valve under that. I put both to roughly 0.08mm, which is the recommended value here in north. I have order already a new spark wire. There was little brittle in it in the top cover but there seems to be an extra cover underneath it.
I have cleaned the variator and kick start system, bendix etc. and put some grease to the places that require it.
Edit: I also changed the battery after the hibernation cos the old one was pretty done. Got a new 7Ah one to replace the 4Ah original.
Yes, the small hose at the top of the valve cover is the crankcase breather and it NEEDS to get fresh clean air from the airbox, just leave that as it is Good luck man, post up with any questions.
Cool, easy job. Next time I do one, I'll make a detailed write up with pics but for now:
A) first pic, cut that large hose and block with a bolt or rubber stopper. (If your feeling ghetto a larger spark plug works great) Done
B) completely remove the large cylinder canister and cut the lines going to it.
C) the "T" that goes to the canister, intake, and petcock you need to re-design so that it goes just from the intake, to the petcock (pro tip you have multiple feet of extra vacuum line from taking the canister out, use it!!!)
D) take the gas tank one way vent off, and route the line from the gas tank vent somewhere clean and out of the way.
Double check that you vacuum line goes just from the intake to petcock, and they are nice and snug. Make sure that you route the gas tank vent slightly ABOVE the level of the gas cap, so in the case of an over-fill it dosent gush out that hose. If you get lost doing it, feel free to post up more pics and I'll walk you through it.
I hate to bust your bubble but the only thing a scooter uses less of is gas, emissions are MUCH higher than modern cars. http://carbonpig.com/article/motorcycles-create-more-greenhouse-gas-emissions-suvs
Less gas is the draw, motorcycles and scooters pollute like MOTHERf***ERS. They actually banned scooters in the most dense city's in China because the pollution was so bad. Most newer motorcycles are getting better, with efi and catalytic converters and everything, still worse than a new car. You don't even want to see the chart for two strokes, it's terrible. Particulate pollution is especially bad, it's the main reason for smog, and the particles travel far and wide. I was watching a documentary and some scientists were studying the soot later in Antarctica from mostly diesel, which emit particulate like 2t. Some spots had an inch later of diesel soot (i would imagine coal too). Anyway were doing our part to save gas, lighten congestion, lighten the abuse the roads get, and best of all its just fun!!!
