perplexed I am

[ghostrider0975]

ok 3 weeks ago m scoot died on me. I worked on it for like a week and a half then I ordered a orange cdi and coil from scrappydog turns out it was just my cdi died now I thought this odd because there is only like 520km on my chino meter which is like what 320ish miles but now that I have changed the coil and cdi my scoot bogs down till it warms up for about 2-3 min now also note that I took the emissions junk off my scoot also..

any ideas??

The auto choke might be messing up.

It seems to me that the most common failure on these is usually the valves need adjusting and the cdi dies.

I have a friend that owns a scooter shop and he does not agree about the cdi, he says it is usually the pick up on the stator failing, I have not heard people saying their stator pick ups fail.

So anyway, check the valve adjustment, and if it still needs to warm up for a while to run right, check the choke(enricher)

i would rank the issues i see cdi valves petcock fuel lines autochokes

question has anyone had anytrouble after switching to the clear yellowish fuel lines? I changed mine over to the new stuff the same time that I changed the cdi and coil and now the fuel line is soft... I am wondering if it may be collapsing when the scoot start to suck down the fuel?? any thouhgts on this??

[Rebel]

Those lines are called tygon tubing, the only problem I know of with those is that they harden much faster than regular fuel line, look cool but I see no real advantage to them unless you just like to see the gas flow through them as you are riding it.

[ghostrider0975]

the reason that I swapped to it is because it is supposed to be more resistant to the ethonal that they are putting in the fuel and isn't supposed to brake down as quick... but the new line has been on for less than 2 weeks and it is now softer than the orignal cheap fuel line that was on my scoot when I bought it..

[Rebel]

Did you actually have rubber degeneration problems?

Yes the tygon would be better for that issue, but if it was not really giving you a problem you might just go back to the neoprene lines. A lot of people that are in parts of the country that have recently (in the last year or two) gone over to alcohol in the gas are expecting problems that probably won't happen with quality lines.

[jmkjr72]

any of the regular fuel lines that you would get at an auto parts store would be just fine

normaly i spend a little more and get fi safe lines they tend to last longer

i never did buy into the hype of ethonal causing issues sure some of the cheaper products are using fuel lines that were not ment for ethonal if people were to start fieling warranty claims and file complaints with the bbb and other sources
this would force the companies that are using parts that theya re not suposed to be

sense the late 70s everything with an internal combustion engine that comes into this country is required by law to be able to run on ethonal

[ghostrider0975]

well not only am I getting the ethonal I'm also in the area where they are startting to cut back the octane levle here in the area of Ky where I am they have cut it down 90 octane for test..so I am having to use octane booster do you think that could be part of my problems??

[Rebel]

Was it pinging on straight 90 octane?

Is the motor stock?

If you have not done something to change the compression and the timing is not advanced from stock timing I think you should be able to run fine on 90 octane. I don't know if Scrappies orange performance CDI has an advanced timing built in or not. Some people say that the only difference in the CDI is that some are rev limited and the others are not, that if you have one that is not rev limited the money for a "performance" one is really wasted because they are really just not limited. There are some that the timing is adjustable though.

If it is not pinging without the octane booster I would not spend money on the additive.
