2 Months, 750+ miles, now some improvements By vintner (Read 960 times)

I don't post much, but thought I would provide an update.

1) I took the MN Motorcycle Safety Foundation and have passed the classes. I will have my new license soon. I took the test on their motorcycle and am still amazed that I passed. That tight box was hard for me to balance, not sure why, but I did it.

2) Some over 750 miles on the YY250T scooter. It has been a great ride to work. No riding this past week, 90-102 degrees is just too hot.

3) I have added LED front blinkers, big improvement on visibility. I have replaced the spark plug (looked a little lean). I have put on a bike speedometer and now know my actual speed.

4) Today, I am adding the Mr Gasket 42S fuel pump. I have had a problem at take off from a stop when I crank open the throttle. I also need to adjust the throttle cable (too much slop) and will add Counteract balancing beads to the front wheel. Maybe the magnet I glued to the wheel for the bike speedometer is throwing off my balance, but I hope the beads smooth the ride.

I get on the site and read a fair amount. From what I have figured out, I have the Honda Clone engine. I do need to research further for the valve adjustment, (external slide valve adjustment), not I have been doing it from feel and sound, but I believe there is a better way.

Thank you all for the helpful posts and especially the pictures and youtube videos. A picture is worth the the thousand words and very helpful on finding 'where that thing is'.

Fuel pump went well and does make a difference on take off from stop as well as the upper end running. Happy with that addition.

Fixed the throttle cable and it now functions as it should. It is much more comfortable to operate.

Counteract balance beads didn't do it for me. At 50 mph and over, the front tire shakes through the handlebars. I will try removing the magnet I added for the bike speedometer and see if it makes any difference. I have to get this smoothed out somehow.

Is this going to come down to removing the wheel from the bike and static balancing? Now that I have the beads in the tire, it is this going to throw off any balancing weight effects?

Good info on the fuel pump, we've had guys asking about an electric pump upgrade.

Was the pump difficult to install? As I understand the balancing beads they will throw off a regular balance job. I had a tire problem like that and it turned out they had installed the tire 180 degrees off. If there's a yellow dot on the tire it's supposed to be opposite the valve stem to compensate for the extra weight. I had a guy do a slow spin balance and the tire sank noticeably to the same spot each time he spun it. Rather than pull the tire off he put a couple grams on the other side and it's smooth as glass.

Hi, Rich. I have essentially the same electric fuel pump on my scooter. I installed it when I did the PDI. I installed it on the frame opposite from the original pump. The inlet of the pump has to be below the fuel tank (gravity feed). The outlet of the pump should be about 45 degrees higher than the inlet. The pump draws about 1 amp and I use a 3 amp fuse on the power line. Works well and you don't have to worry about a dry carb after a long period of not operating the scoot.

Rich, When I removed the hockey puck fuel pump, I used one of the holes to mount the new pump and did drill an additional hole for the second mounting tab. To be honest, the job would have gone much faster had I grabbed the corded drill and not the cordless drill. The battery would hit the frame so I tried an extension for the drill bit. The corded drill would work just fine without a drill bit extension. That was a 'duh' moment.

I'll attempt to post pictures soon.

If there is no significant change with the balancing beads for your front tire it is probably out of round and needs replaced -- even if it is brand new. You can perfectly balance a square wheel but it will never roll smoothly. Check the wheel for out of round at the bead and run-out as well.
