Co2 · 09-12-2015, 02:01 AM

Another carburated version of ZS177MM my moto Xmotos XZ250RM , fabricated mounted coming with DELLORTO PHBE 34 mm , i buy this moto on 2013 , but moto model is product 2011 , and probably sleep in fabrica , and first day surprised my exhaust color chanced Gold yellow :(

After day i research and found problem is carburator in old benzin carb bowl benzin returned paste ( 2 year stay in old test benzin), blocked carb jets bad surprise.

But Dellorto phbe 34mm carb , non vacum type, spray type i think generally used hot italian 2 stroke bikes , basic constuction, basic maintenance and clean, i like.

I'm try KOSO / OSO 32mm carb , but poor performance (probably need , big jet's, low rpm good but high rpm poor probblem , and manifold gasket harmony problem)

Spark plug trying changing, moto coming DENSO U24 ESR-NB ( good performance) , (big head type"spark plug head attent") ,

Sparkplug crossreference found sad NGK CR8 , i try iridium version CR8EIX ( low rpm very good, but high.. Denso better than NGK)

Owner manual writed sparkplug adviced Champion RG6YC , i try found that sparkplug but cant found , idk how performance or stable..

İgnition coil , i found a old waste Skyteam 200cc cross bike , old ignition coil (same build type) , and i tested Skyteam 200cc ignition coil better than orginal coil , but old and dirty, i try found zero new cant found.

I was wondering , which other carburator types on harmony ZS177mm ?

( forgive me please, grammer and poor english, my age 36 and populer Turk terminology said " age is 35 Half of the way " ,^^ im happy in this forum platform )
