    Hey fellow HS riders, does anyone know where I can get cheap clutch springs for the HS 142-F, I am running out soon... These things break so fast. I use to get them from bikeberry for $2 a spring plus shipping, which is just ridiculous. So, I found a China source but the springs are 38mm and not 44mm and has 9 spring coils versus 10 coils. Would it be okay if I use that instead? It is about $0.90 per spring (10 order).

    So, I went ahead and bought it. I am not sure but perhaps the spring that I checked was unusually long and 44mm is not the standard size. But, 6mm difference is like 1/4 an inch so maybe these would be fine. Also, 9 coils versus the 10 coils can help with lowering the rpm engagement of the centripetal clutch. It is from China so I will get it in 2-4 weeks. Will report back then to see if these works for HS 142-F.

    So, I ran out of springs and had to get something quick so I tried getting the cheap clutch pads for pocket bikes from a US seller thinking if I can't use the pad I will just use the springs - I did measure it with an inch ruler... I got the pad today and it fits and runs fine in a small test. I mean compared to the prices from gasbike and bikeberry this seems great ($30 compare to $6 for US seller). The 15 replacement springs from China I ordered for $7 is still on its way...

    I mean I am not sure if I am just dense and realizing that this clutch pad works fine too and the springs as well...

    Its too bad i can't use it on my tapered shaft...I bought the hd clutch from staton for over $40 after my stock clutch asploded from 2 weeks of hills. Its still great, don't see much problem of late engagement over stock. I'd love to get softer springs just for that extra umph from takeoff, however.

    When I get the 15 shorter springs (4mm) with 9 coils instead of 10, I can give you a set (3) and you can help me test if it is softer if your staton clutch uses them. Of course, the springs will be new and stiff and need some work in but yeah after a while...

    Not sure if it'll be compatible... 4137.jpg Huge difference. Been looking for softer ones that look similar for a bit now.

    Yeah, haha, they are different. Those springs sure look beefy.

    I received the 15 springs from China... Just a day after I got the replacement clutch from california :confused:. This is possibly the fastest Ive receive something from China, 7 days. Wow

    When does the clutch begin engagement with the new springs and what is the stall speed? Also let us know if and when one pops.

    I just went on a short 3 mile trip with the new clutch and of course the clutch was super tight and low end torque was horrible. Top grip and speed was the same about 32-33 mph. I am going to take out the new clutch and put in the old with new springs tomorrow to see. The old clutch arms are very loose due to use so that will help with low end torque versus the new clutch with really stiff arms.

    Also, I might be a dummy the new springs might be the same as the old. Maybe, I didn't count right 9 vs 10 (seems like 10) and the old spring I used for measurement might have been lengthen from engine use.

    If it engages too soon it might stall while standing at an idle, if it locks too soon you'll see a drop in your torque because it'll be well below the rpm for peak torque at full lock. Do you have a tach? As long as there is no slippage both clutches they should have an equal top speed, it's engagement and stall speed that should be of concern. What rpm does the new clutch begin to bite and what rpm is full lock?

    Oke, so I put the old clutch back on with the loose arms and guess what it broke apart on me... I think it musta been the 35mph I was going. So, the arm came completely out of the bolt hole in the clutch and I am not gonna try to put it back in since it failed once already.

    The springs performed the same as my old springs. The springs are most likely the same springs from BikeBerry and that comes with these kits. I think when I was comparing the two I used an old spring that had wear so it was longer than a new spring and I probably miscounted the number of coils in the new spring, it has 10 coils (same as springs from the kit).

    I put the new clutch back in and while the pick up isn't as good as my old clutch with loose arms I think it is okay. Conclusion, you can buy replacement springs on eBay for $0.47 a pop with fast shipping from China (~ one week).
