Technical | How To / Bystarter check
« on: February 20, 2014, 01:11:54 PM »
I tried to check the bystarter on my 2006 Kymco Bet and Win 250 by taking it out before start up,  then measuring the plunger ,then reinstalled the bystarter and started the scooter up and ran it until warmed up(10-15min).   After warm up I wanted to remove the bystarter in order to measure the length of the plunger to see if it changed.   I tried to pull the bystarter out after removing the hold down screw,  but the plunger seemed to be stuck and I didn't want to force it out so I reinstalled it.   Is this a normal thing or not?     I know that the bystarter works off the carb as I tested it by direct hook up to my battery.   

Thanks all

Today I took all the air side apart ( air cleaner , the tube and air box that runs from the front to the air cleaner compartment ,  the oil evaporater tube coming off the valve cover,  drip tube form that tube),.   When I took the air box off  which sits up front there was evidence of a mouse nest ( pieces of fabric , wood shavings etc,  which one mechanic found in the air cleaner compartment right after I bought it .   So the mouse went into that compartment , then through the 1 1/4 inch dia tube , then through the air box and built a nest in front of that. I figured I would check the bystarter so I took it off and measured the length of the plunger before warmup.  After all that I started it up with out the air cleaner in and the other tubes off and it started up fine,  so I reinstalled all the air air cleaner system and it seemed to run ok still. I was going to take the bystarter off to remeasure after warm up , but could not pull it all the way out,  which I assumed meant that the plunger went down as it was supposed to do,  so I re installed.    I then rechecked the mix screw and found that I could turn in some more from where it was and after turning in I found that it did change how it ran .  I now have it at at about 3/4 to 1 turn out from seating and it seems to be running ok now,  but I need to take it out on the road once the snow an ice are off the roads to see how it performs .   

Thanks again!!

After reinstall of carb with 38 slow jet and 108 main jet , new irridium dr7iex-9 ngk plug, new gas ,new fuel filter, I started my scooter up today.  After adjusting the idle knob and idle mixture screw  I got it to keep running .  After warm up I pulled the plug that i just installed which was sooty on the end . I then checked the compression with WOT and cranking it over where it reached 180 on the gauge,  which seemed good to me.   I reinstalled the same plug after wiping off some of the soot and restarted and turned the mixture screw in thinking that it should lean it out some and as I turned the screw clockwise it did'nt change how it ran.  There is no hesitation when throttling up,  but sometimes acts like it is going to stall out at sitting idle.   I have not had it out on the road yet for a run,  so all my tests have been with the scoot on its stand.   Still need to check for vacuum leaks,  but a vacuum leak would make it run lean , right?

Thanks all.

So far I have put the 38 pilot and the 108 on the main jet  after another carb cleaning and checked the bystarter which checks out OK hooked up to my battery and on the carb .  I also drained the gas it came with and filled the tank up with 93 octane gas.  The bike is outside with a cover on it surrounded by snow and I have not had a decent warm day here to reinstall the carb to check the newer jets,  so once I do that I'll see how it runs and if I still have a problem  I'll go on to checking out  for vaccum leaks, then valve settings and then cylinder compression.  .I do have a service manual.   I will keep you posted.

Thanks again all!

So rice10562,  What do you mean by two brothers cf250?  How did your bet and win 250 run with the smaller jets ?  I haven't tried mine with larger jets yet.   How did you end up with using a 125 main jet and how does it run with that set up?

Thanks

I live near Valley Forge PA so I don't think altitude is a issue. I bought it used , Dec 2013 .  I was having problems with stalling out when coming to a stop and and some hesitation on initial throttle up so I took the carb apart for cleaning thinking that could be the issue. While cleaning I looked at the jet sizes and discovered that they were different than those seen in several specs.  Could that difference in jet sizes be an issue?  After reinstall I am still having same issues.  My next steps are to check bystarter then valve clearances and cylinder compression.

Thanks

Can anyone tell me the correct size jets for a 2006 Kymco Bet and Win 250.  Mine has a 35 slow jet and a 102 main jet.  I have seen specs that say 38 for the slow jet and 108 for the main jet.  So what size should they be?

Thanks all.
