its like 50 2 stroke. i spoke with guy in local scooter store and he thinks that its already derestricted based on speeds i am hitting. i can go 40+/- no hills. i went almost 50 on steep downhill by my house. my problem is going up that hill. even with running start at the top of hill i am only going 10. what does exhaust washer do? not sure exactly where to look for the washer but will do some more research. thanks
Here's what Gosku said in the variator tuning thread about his People and hills , " Today I installed Malossi torsion controller, changed the belt to a new one (OEM of course) and changed the OEM rollers to Malossi 7 grams. The spring is the stock one. The difference is huge. According to my speedometer (which I have fixed today too) I'm doing above 60kmh when going uphill, and the hills are actually quite steep. Before changes I managed to ride 40kmh at best. Another good thing is that if I brake when riding uphill, I can then gain the 60kmh again with no problem. The engine stays at good RPMs no matter the terrain. On flat I'm fast to 70kmh, then it slows down but I'm nearly able to get to the limit on my speedo which is 80kmh. Overall I'm very satisfied and do not want to mess with torsion springs / rollers anymore because it feels like I have already found the sweet spot"
Keep in mind he has a Tecnigas Next R pipe which adds quite a bit of power. On my stock unrestricted People, I just changed to lighter rollers, 6 grams, and that helped me quite a bit on hills and I didn't lose any top speed. I'm planning on adding a performance exhaust to help more on the hills. Will post back later on how that goes.
