Yamaha Thailand No Cut-Off CDI Unit for Yamaha 135LC

Yamaha Thailand No Cut-Off CDI for 135LC

My friend Shah has sent me a new addition to the already many variation of Yamaha 135LC CDI. This one is sourced from Yamaha Thailand which have one special feature that we don’t have in Malaysia, that is no cut-off. I’m not sure whether this one is referred to RPM limit cut-off or speed limit cut-off.
Based on Shah’s interview with the mechanic at the supplier shop, it is said that this CDI from Thailand is much better compared to BRT and Rextor from Indonesia. Also, I’m not sure about this. By better, it means that the ignition spark and timing are good all around the RPM.
I have spoken to the mechanic who work at Malaysian Cub Prix about racing CDI and he replied to me that he only use original stock Yamaha CDI unit, but, tuned at Hong Leong Yamaha for each and every track for the suitable ignition timings and ignition sparks. Therefore, I do really think that this Yamaha CDI unit from Thailand is as good as told by the mechanic which my friend has interviewed.
Final opinion is up to you to try it yourself. Don’t just take my words for it, buy it, feel it and share it here for all of us to know.

  1. harge cdi nie brape??
    hmm..klau nk tukar spoket,,,saiz brape yg ok???sbb pakai saiz 37 mcm kurang top..bleyh pegi 130 jew…kalau 39 bleyh pegi 140..
    klau pakai high cam..xde effect k kat enjin??

  2. hm,benarkah kelajuan lc bru yg hanya mencpai klajuan 140km/h adalah dsebabkan cdi pda mt0 lc bru tlah di cut??.. Jika kita guna cdi lc 1st mdel,b0lehkah mt0 kita mencpai klajuan 180km/h sperti mt0 lc 1st mdel??..

  3. hm,mmg bnar n klau pandai raider,mybe bleh lbh lg cket.. Stiap kli test mesin Lc 1st mdel n 2st mdel,cmf0rm Lc 1st mdel akan mendahului dri smua aspek antranya pikup n msa utk mncpai klajuan maksimum,sdangkan kdua-dua mt0r msih standard.. Hm,jika sy hanya tkar high cam,sp0cket & cdi,apakah klebihan & kburukannya?

    1. mungkin ada benarnya kerana 1st model LC autoclutch enjinnya buatan jepun dimana boleh dilihat pada kulit enjin y ditulis ‘Made in Japan’.
      High cam akan bg higher valve lift utk kemasukan udara dan petrol y lebih banyak kedalam kebuk pembakaran. Seperti sistem VTEC y ada dua stage cam, iaitu low cam utk jimat minyak pada RPM rendah dan high cam utk prestasi y lebih namun kurang kecekapan penggunaan minyak. Motor x boleh pasang sistem VTEC, tp boleh pakai high cam terus. Jadi kuasa sentiasa ada pada RPM rendah mahupun pada RPM tinggi.
      CDI tu pulak cuma bagi spark y lebih kuat dan tiada RPM/speed cut-off.
      Sprocket kecik pada belakang akan bg top speed y lg tinggi.

  4. sy guna Lc135.. Tp kne klajuan maksimumnya hanya 140kmh sahaja??sedangkan mt0 Lc first editi0n leh pecut sampai 180kmh.. Leh cdangkan langkah yg perlu sy ambil utk mningktkn klajua mt0 sya ni??

        1. byk boleh buat; guna high cam, big valve head, tukar sprocket, tukar block. tp klu xnak tukar semua tu, cari saja motor LC 1st model 2ndhand. satu lagi, mmg benar ke LC 1st model boleh pergi sampai 180km/h? atau dgr2 crita org saja?
