20 Steps : ZXR250 Valve Clearance Check Only (NO PIC YET)

Memandangkan kamera takdak buat masa ni.. aku tulis dalam bentuk ayat dulu..

1. Bukak fairing kiri & kanan.
2. Keringkan minyak enjin, simpan dalam bekas bersih.
3. Bukak coil cover. (guna socket 8mm)
4. Letak coil cover atas tin biskut sbb ada wayar magnet melekat.
(magnet takyah bukak)
5. Longgarkan 4 bolt radiator, 'rehat'kan radiator kat mudguard. lapik dgn kain.

6. Cabut cable plug
7. Guna spanar 10mm, bukak 4 bolt head cover.
8. Keluarkan head cover punye gasket (getah) & plug gasket (plastik bulat).
9. Bukak plug silinder 1 & silinder 4.
10. Masukkan straw plastik kat silinder 1.

11. Gunakan spanar yg sesuai, pusing alternator sampai :-
a) straw berada dlm keadaan paling tinggi DAN
b) inlet & ekzos camshaft free, tak tekan valve. (utk dapat Top Dead Center)
12. Ukur clearance INLET silinder #1, #3 (0.15mm ~ 0.24mm)
13. Ukur clearance EKZOS siinder #1, #2 (0.20mm ~ 0.29mm)
14. Dah siap, masukkan straw kat dalam silinder no 4.
15. Ulang langkah (11).

16. Ukur clearance INLET silinder #2, #4 (0.15mm ~ 0.24mm)
17. Ukur clearance EKZOS siinder #3, #4 (0.20mm ~ 0.29mm)
18. Jika shim TIDAK perlu ditukar, pasang semula komponen.
19. Jangan lupa letak Silicone Gasket pada head cover & coil cover.
20. Jangan lupa masukkan kembali minyak engine.

[] Kalau bacaan clearance tu OK, bolehlah anda melenjan moto anda Very Happy
[] Kalau bacaan ada yang TAK OK, bersedia utk menukar shim anda.
[] Nak tukar shim, bersambung di topik yg lain. Very Happy
[] Pic coming soon although not very soon enough
[] Dont understand Malay? PM Me, i'll be glad to assist / translate.
