People 50 / Re: Actual hp/torque/rpm for 2003 People 50 2t
« on: May 11, 2012, 02:58:27 PM »
Hi Axy. Actually I would be ok with cruising a solid 45mph so I was assuming that in order to do that for prolonged periods of cruising time the engine would need the ability to do a little more. This is assuming that you don't want to cruise WOT. Currently at the max. speed of 43mph my rpms are at 7500. If this little engine can run at that speed all day long then I'll save money on upgrades. Zombie's suggestion of moving the power band higher to keep the engine cooler seemed logical in that maybe with the mods the engine can run at 8500 but I would not expect to hold that rpm for cruising. Therefore if i cruise at 45mph/7800rpm? then I have a cooler, safer engine with some safety overhead. If the consensus is that this engine CAN run at 7500 all day long stock, then It will stay as-is. Thanks for you help.

Zombie, thanks for the short answer. Based on your other postings you seem very knowledgable. Here is my current plan based on the goal of increasing top end by moving power band of motor up to sustain higher rpms.

Leo Vince Touring exhaust with restriction ring removed if it has one.
Current main jet is #85 so get a 90,92,95 jet. Start with 95 and work down if needed. Do I need to change/adjust the needle as well? More air intake?
Experiment with roller weights around the 5-8gm range, keep clutch parts as-is.

Comments or suggestions are appreciated. Thanks.

Nice forum, had to join! After a lot of conflicting information, I could use some help please. The service manual for the 2003 People 50 2t says power band is 1.76kw@5400 and .33kg@4600. However, I read somewhere else that it is actually 2.72kw@6500 and .4nm@6000.

Here's what the KymcoUSA tech guy told me. He was reading off a document and said he did not know first hand. Power band is 1.76@5400 and the stock CDI with green wires connected is limited to about 5600 rpm. Disconnecting that wire would employ a new limit of 7500 rpm. It is not "unlimited" but protects the motor at it's limits. He also stated that he could recommend a max. sustained cruising rpm of 6000-6500 with short runs (<=10minutes) at 7000-7500 rpm.

With stock engine,  cdi at 7500 /Naraku cvt with 8g weights, acceleration for me at 190lbs seems very acceptable. Up to a verified 35mph in 8 seconds from stop. Top speed verified is 43 with 48 on speedo. I'm just looking to be able to cruise at "real" 50 and not be the pokey one on local roads where limits are <=50mph. I know a lot of mods will get me up to speed quicker but I'm happy where I am now. Just looking for a little more top end. CVT is running at max ratio based on magic marker wear pattern.

So my questions are the following: What is the actual power band? What is the max. cruising RPM on stock motor for continued periods? Is he being safe with his numbers? Does anyone have real-world knowledge for example that they have been running xxxx rpms for long periods with no issues on stock engine. And lastly would just allowing engine to turn more rpms accomplish this and if not how to actually get there?

Thanks for your help!
