does the 3 clutch and T springs wearout?
I put about 4500 mi. on the springs and now they feel like the orig. sprg.
So, what I did is, I took the spings off the clutch and gave them a half turn to tighten. It worked for a while now getting slower.

So, what I did is, I took the spings off the clutch and gave them a half turn to tighten. It worked for a while now getting slower. Depends on the rating of the springs. I run 2k clutch springs and 1.5k contra springs with 5 gram slider weights with my big bore kit. My clutch springs hold up for about 2,000 miles whereas the contra spring lasts around 1,000 miles. They get weak from heat and from fighting the roller weights..and this is common. Stock springs last longer because they do not suffer that extra stress..but then they don't give the performance we seek..hence the reason we replaced them with performance springs. Anytime we seek performance whether a car..scoot..motorcycle atv etc..there is a going to be a trade off. Another is that my piston rings don't last as long as stock 40mm ones either. Again just a small price I pay for the jet like performance of my setup. I am not understanding what you mean where you say..you gave the springs a half turn to tighten them. They are not adjustable..or was your clutch nut loose? Glenn |

Glenn I'm just a fifty no bore. 6g sliders shaved, this gives awesome perfomance. { run the sliders upside down [and wow, the take off but not much top speed perf.] about 5k mi. or untill you get two seperate flat spots on them. (file the sliders, keeping shape, 1mm or about 2mm from the center ring) Great acceleration from 20-45 on the chine-o-meter and lacks from 45-52ish. whereas, when i first bought them, put in the right way, good acceleration all the way through the band untill 45 where it normaly slacks. I figure the springs will take the rest. (Acceleration) About the springs, you know how when you take a coiled cable to lock up with, grab the two ends and twist it one way and the coil gets bigger the other way gets smaller. Well, with rod bending, to make suspension coils, works the same way only the spring is set to a specified spec you can effect the perf. of the spring by this method. Stretching the T-spring does the same as twisting. Since you can't mess with the diameter. The down fall of this method is the springs wear faster cause of the stress from this method. though, it would be great for a drag secret. This was done as a test to see if it was wear that is effecting the perforance of the scoot. And, this thread was to clarify. |

Ok..sounds like slider wear also. True as you said..you can reshape a spring..but as ya know..once you do it must be annealed again to regain its temper. Regardless..they do wear quicker than stock springs..even without a Big Bore Kit. Flipping them over does give super hot take off..and I have done this just to drag race folks. But for normal daily driving long distances as I do..I install them normally so my 70cc BBK can get me up to 56mph..yet cruise easily at 50mph without the engine revving as high. Anyway I would also check engine compression as it fades slowly..therefore we miss it and just notice a slight and gradual performance decrease. But it also sounds like weights and springs need to be replaced. Filing them down also keeps the variator from opening all the way..which degrades speed..  |
