During my previous clutch outer sole replacement, same time I’ve put in a new set of clutch spring (6 pcs). Expect it will improve the clutch gripping and improve power delivery. Unfortunately there is almost no improvement. The original SYM T2 clutch spring is just too soft in my opinion. Many Taiwan’s owner has replaced with WRRP after market clutch spring. These springs has higher compression and will push the clutch plate stronger, thus reduce clutch slip or power loss.
Fortunately we have Yamaha LC135 moped in Malaysia (Indonesia’s Jupiter / Thailand’s Spark). The SYM T2 clutch spring is almost identical with the Lc135. Only the spring diameter is approx 2mm larger, but it should bring no harm. The length of both spring is same. Of course we don’t install the original 135cc clutch spring into a 250cc engine, but go for aftermarket version – Faito Zero II Clutch Spring.
Faito is a Malaysian motorcycle parts manufacturer. The product brand name and packaging are mimic Japanese goods, very eye catching and professional looking. Faito has two clutch spring model, Sumo and Zero II. Sumo is less strength than the Zero II. I was unable to do a test with these two because packaging is sealed. I opt for Zero II version. The LC135 owner told me about his bike has more power and gear engagement is same as before, no difficulty in gear shifting. Since T2 has bigger engine, the Zero II shouldn’t create any problem too. I bought 2 packs (total 8 pcs) of Zero II because T2 requires 6 pcs. The price is quite reasonable at RM70.
After installed the Faito Zero II clutch spring, clutch lever became slightly harder but the transmission is very accurate and without delay. The power just flow all out upon throttle opened. Acceleration is quicker and riding experience just add another star! 🙂 I’m a much happier T2 rider now.
