People 50 / Re: Real Speed (GPS) vs Speedo
« on: May 18, 2011, 01:18:21 PM »
I took the jet size to a .78mm and it pulls better up hills. I will have to do a plug chop to see if I'm running a little on the rich side. If I am running a tad rich, I probably won't do anything about it until I get a new pipe.
A couple of people have recommended the Leo Vince SP3 pipe which is what I have my eye on.

rejetting is easy. ask the shop for some extra jets and get yourself som micro drill bits. I did this last night. I opened the mainjet up one size and will do a plug chop (running full throttle for at least a mile with a NEW plug, kill the engine pull over and check plug tip for color) to see if I need to open up the air box more. I have the exact same bike as you down to the year. speedo maxes at 45 when on a flat road but GPS says 41-42. I'll post later to tell ya how the scoot behaves with the new jet size.
what pipe are you looking into?? I was advised not to go with an open air filter. what kind of performance are you shooting for??

does it run wide open all the time or just when it first warms up?? It sounds like to me its either your idle jet or your air mixture setting.

sounds like the same problem I had when I got the scoot out of storage. I did the same thing you did with taking the carb off and just clearing out the jets. It took a long time of kicking before it started, seriously like a straight minute of constant kicking to get it to start. I would try changing the spark plug and just keep trying to kick start it. I would have to kick it like 10 times in a row before it would start, but now I replaced my battery so I don't have to kick start it any more (at least for a while anyway).
Good luck.

I opened the carb up to drain it and to unclog the jets; stupid me left a half tank of gas over the winter. The main jet had a M75 on it, leads me to believe that the main jet is a 75. I did a plug chop last fall and what I could tell is that the scooter was running just a little on the lean side.
The exhaust might not be deresricted, I took it off last year and there was no "cone" on the intake side BUT there looks to be something simular to a cone restriction on the very end of the exhaust.
By the way I took along a GPS unit to see exactly what MPH I was hitting. *sigh* Speedo says 45, GPS says 41.
This summer I might take the carb off again and take a weilding tip cleaner (or a micro drill bit set) and open it up to the next size up.
I'll start saving my pennies for a new exhaust. Any one recommend which Technigas??

that is what I paid for mine without the perfomance parts added but they were kind enought to change out the boss drive. I would jump on that!! Nice deal

that is what I was thinking. But what can be said about the exhaust? I don't have the cash to plop down on exhaust. will the stock exhaust be able to keep up with opening the jet and air box??

I have a 2005 people 50 2t, de-restricted cdi and boss drive. I have taken off the exhaust and could not see any restrictions and do not believe it to be one of the overly restricted versions (no extra tubes coming off exhaust). everything else is stock and I get a good 45mph. I want to acheive a solid 50-55 (actual mph).
My plan is to take the carb off and open up the main jet and open up the air filter box. The manuals say the stock jet is #85 (.85mm). I am thinking about opening it to #90(.91mm) - #92 (.92) by drilling the stock jet. I am going to open the air box up by drilling at least one 1/4 inch hole. I might go for a performance cone filter in place of the air filter box but I think it would be a waste if I can't get a hold of a better exhaust.
Will my plan get me to where I want to be without a performance exhaust???

Isn't #85 the stock size, at least that what it says in the manual. Has anyone tried restricting the air flow instead of changing out the jets?? In colder weather air is more dense so if the mixture is too lean then couldn't you just restrict the air flow?
Maybe I'm just stupid.

I got the scoot out of storage and my goal for this year is to get over 50 mph. scooter is de-restricted, cdi is de-restricted. now I am going to pull the carb out and open the stock #85 main jet. I'm shooting for about .92mm on the main jet and at least one 1/4 inch hole in the filter box. Can't wait for slightly warmer weather!!

quick question for future reference, when you remove the carb do you have to pinch off the fuel and/or oil line? Or does the throttle (slide needle) take care of that for you??

Thanks Art! During the winter months I plan on pulling the whole motor out and possibly go with a bigger cylinder kit either with or without the stock jug. I've heard interesting things about the Malossi big bore kits can sieze in cold weather because of the different metals between the jug and the piston, temperature expansion/contraction. I kind of doubt it though, given all the testomony here that Malossi is the shizznit.
I'll either go with a kit or just rebuild if the stock piston doesn't seem that beat-up. What I WILL DO is rejet, new exhaust (chrome Technigas), free flow air filter cone, paint flat black, and add some LED running lights to the front where the dummy light covers are.
Thats my plan.
I brew beer as my other hobby, I try to do most of it during the summer.

It'll be a while till I tinker with the scoot. Our next "bundle of joy" is expected soon. I promised SWMBO that I would put off any more tinkering until fall.

Funny, I am the QA guy at a place that manufacturs particle accelleraters, pelletron.com. I am blessed to work at a place that has a great machine shop. The parts that come out of the shop have to be within .005" tolerances. I'll have to bother one of the scooter shops to see if they have any jets for my carb.
Thanks guys!
