People 250 / Has anyone fitted a mechanical "needle sweep" style tachometer?
« on: September 02, 2010, 08:03:56 PM »
Hi,

 I'd like to put a Tach on my 2006 P250 but i'm having difficulty finding one. I've seen the digital ones, but i'm old school and much prefer mechanical gauges.

Thanks in advance

OK, Happy Days...it's fixed! ;D

 Firstly i need to give myself a kicking for going against first thoughts and spending hours looking at irrelevant things. Secondly, and more importantly, at least now i have a much better knowledge about the transmission and drive unit.

 It was a fuel problem. As soon as i got into the carb and saw that it was a diaphragm variable throat i knew straight away what the problem was. The Diaphragm seal where the cover goes over had not been installed correctly and was leaking air. I've seen this a thousand times on jetski's i've worked on and felt an instant feeling of embarrasment  :-[ What i spent hours taking apart and researching on here, was a simple 30 second fix.

 Now this is more like it! It is now great to use on the road, pulls great from a standstill and hit's 60 with ease. Couldn't really go over that here in the Northern Virginia beltway area, but i could tell if it were not for the traffic it would go more. Still getting used to that rear brake not being a clutch, but otherwise a great bike to be on in the traffic. I'll not miss the big manual gearbox bikes in the DC traffic that's for sure.

 Thanks for the input, always appreciated.

Here's some pic's. I think you got something wrong with the veriater. once assembled correctly you have to hold it in place as you slide it back into place,if not the rollers can turn sideways on you


Thanks for the pics.

The only thing i've noticed is that my rollers are pale yellow and not black. May be completely irrelevant, but just in case it could be something, i may as well mention it.

The belt is new and geuine. The part # matches what's listed as a replacement. As for the rollers, i would assume they were also the correct genuine ones as they were all bought at the same time. With not having worked on one of these before, i kind of dropped the ball and the roller/slider assembley was upside down in my hands and fell apart, so i can not confirm how they were positiond when installed. The cones where the belt runs seemed to be ok, but i haven't pulled the clutch apart to make sure that's all ok, just checked the lining depth.

 My thing with theis is the fact that under any kind of load at all it will not get up, even just the load of the drive freewheeling. I'm just stumped. i'm going to try to find some carb settings and take a look at that.

Hi all,

 A couple of days ago I entered the realm of scootering. I have had bikes all of my life, but usually the race replica style with a couple of naked's over the years. This scooter is a new world to me, especially the automatic transmission.

 I bought a 2006 People 250. It was primarily intended for my wife to use as a commuter, but i have to admit I was really wanting to get on it myself. She test rode it, liked it, and the deal was done.

 Well, when i took it out, it just wasn't right at all. It was just gutless! I am used to bigger bikes with more power, but for a 1st bike for my wife i got her a Ninja 250, and this was not even comparable. Something has to be wrong.

 I read through a few tests before i bought it that said it was quite a brisk scooter to ride, one of the best ones out there performance wise. This one we have won't go over 50 mph with me on it (190lbs) and that takes about 20 seconds to hit! It doesn't even sound like it's even trying to rev hard. It was supposed to have had a new belt and rollers just before i got it.

 Being mechanically competant, i got stuck into trying to find what could be wrong. I took the drive cover and pulley assemblies off. Belt and rollers were new and well within spec. Clutch was also within spec. There are still a couple of measurements i need to check that are in the manual that i have not got around to.

 Replaced the spark plug and fuel filter - verified there was no fuel restriction, checked the valves and adjusted (Thought i found my problem with a too small gap on the inlet side, but it didn't change anything when i rode it afterwards)

 With the engine cold i got 130PSI cylinder pressure, warm i got 180 PSI. What are your thoughts on this, the manual states the equivalent of 213PSI, and i'm not sure if thats a warm or cold reading? I would assume warm.

 The spark plug looks like it may be a tad on the lean side being a bit whiter than i would like.

 With the drive belt off, the engine will rev up high like i would expect it to, with the belt on with bike on center stand it just doesn't want to rev at all. When i'm riding, it just feels and sounds like i'm at half throttle. I have checked the carb to verify the butterfly is opening all the way.

 I would assume if it was a drive problem, the engine would still rev properly, and the drive would just slip and i would smell the belt? There is new gear oil in the diff and it spins freely. It's just weird that it just won't rev. I'm thinking maybe a carb problem or a weak spark box?????????? 

 I'm running out of ideas and would appreciate any input you guys have regarding this problem. Maybe it's something simple that i'm just not seeing.

 Not really the introduction to scootering i was looking for, but it keeps me busy i suppose  ;D
