It may apply to UCE TwinSpark 350 applications, but order only after confirming KLG00004/A in the old part, dealer bill or catalogue for that exact motorcycle.
Is this the same as KLK00004/A?
No. KLK00004/A is a clutch assembly without drum. KLG00004/A is a decompressor kit assembly.
Will this fix hard starting?
Only if the hard-starting issue is correctly diagnosed as decompressor-kit related. Hard starting can also be caused by battery, starter motor, relay, sprag clutch, tappet setting, compression or wiring faults.
