I now have put a 1000 miles on my 2002 silverwing in a month started with 3000 on it noticed i now have to give it a hairs width of throttle to start still getting 50mpg anything to be concern about

Sometimes I have to give just a touch of throttle but I think it is because I messed with the fuel mixture screws. I am going to take it in so they can adjust it with the equipment that is required. But I wouldn't worry about it though. I would take Bill's advice about the cleaner. I do that every few months just in case.

my 02 sw starts and and idles ok when stone cold but when its get up to operating temp it will not idle and stumbles until about 3000 rpm. going to a different gas station quit using ethanol used fuel system cleaner for 3 tankfulls. put in new plugs old ones black, new now look same after 15 minutes, air cleaner dirty but not that bad ran it without no difference.
any suggestions closest honda dealer one hour away.
4400 miles

Hi Eldon,

It almost sounds like your Fuel Pressure Regulator might be acting up. Best to test fuel pressure in your FI system. Darn things do not last forever.

Check to make certain you are using the correct plugs - by correct I mean the plugs should fall within the correct operating temperature range. Verify that the gap is set properly. Check this thread: http://www.silverwing600.com/maintenance-tips-and-hints-f7/spark-plug-replacement-t105.htm?highlight=plug

the plugs are the same as i took out ngk cr8eh 9 gap is .035
i will try the local motorcycle mechanic he works on a wide variety
have only seen one maxiscoot in the area in past year.

This is gonna sound silly, but change the air filter.

Mine does that when I need to clean it.

When I asked the dealer about starting he said "let Mr. Honda start your Scoot". If the scooter doesn't start there is something wrong. don't give it gas, make sure it in a stating configuration.He say it has been engineered to start without difficulty.

what size fitting do you need to check fuel pressure and if i read correct 43 psi at idle

Hi Eldon,

43 PSI at idle (1300 rpm) is right on the mark. There is a service check bolt that is removed (carefully) and the fuel pressure gauge gets installed where the bolt is removed. There are alot of cautions when working on high pressure fuel systems.

This is what gets me, the service check bolt is located on the fuel tank and you will need to remove the center cover to access it.

Hi bigbird,

Some where, there is a picture of a silverwing with all the tupperware removed. I just can't remember where. Darn it...well that's it my memory is going....and fast.

I found one. Totally naked.

....or it could be a.... BRAIN FART!!!!!

what is involved in removing center cover
or do i shotgun it and have the mechanic replacedthe fuel regular very tight budget

OK, here we go.

1. Remove the seat

2. Remove the lamp/bulb out of the cargo area.

3. Remove maintenance lid.

4. Remove the floor skirts.

5. Remove passengers foot steps.

Then....

6. Remove the screws and washer bolts on the floor boards and remove the floor boards.

That was easy!

thank you
so if understand the regulator its not working right its dumping to much fuel causing it to flood and not to run smooth until higher rpms
thanks again

What Happens is the electric fuel pump causes pressure much higher then 43 psi in front of the PR (Pressure Regulator). The PR lets alot of that un-used pressured fuel to return to the fuel tank.

If your scooters PR is letting to much pressure build up, it will cause to much gas to spray out of the fuel injectors, causing the motor to run to rich.

Testing PR is really a good thing to do on an earlier scooter. It also checks your fuel pump.

I just did a look see on Ebay and guess what I found! Honda Fuel Pressure Gauge 07406-004000A.

This is the gauge that honda uses on the Silverwing also. You will need to bid on it, but don't until it's almost done. It has no bids at this time and is at $5.00 with $9.00 shipping. One hell of a deal if you can score this for $5.00

You can always call the Honda Dealership near you. Knowing the price of Original HONDA tools, (est) would be around $45.00-$60.00 Now that is a guess. So go find out if you are really interested.

I just called the dealer here in Tulsa.....And the price is: $74.42 and you need to change the last letter in the Honda part number to "B".

Gee, that darn thing is alot.

just took it to local mechanic withe tupperware off he thinks he got the fitting he will call back lets hope be out of service a week if has to order parts

guess that means no J&P cycle open house this weekend

48 psi when cold ordered a new regulator should get here by monday

just got my wing back 100 parts and labor took half the tupperware off myself why it needs so many screws to hold air cleaner on beyond me
