First ALL MOTOR SETUP in Karachi on a motor bike :)

Hv installed wiseco hi compression alluminium - forged piston 61mm - 13mm pin

hi performance racing cam shaft

Hi performance 55mm stroker crank

cylinder stud kit

hv installed titanium valve springs retainer

bigger intake and exhaust valve
30mm intake valve
24.5 exhaust valve
5mm valve stem

ceramic coating alluminium cylinder

kitaco oil pump kit

racing CDI with harness

Hv installed silver head gaskit 1mm

but the problem is tht i cant control its knocking increase head gaskit size to 1.5mm but no result then 1.75mm find result so thought knocking is dere becuase of lean fuel so increase the fuel by havng bigger jets first the jet size was 92 then installed 104.. knocking ends in 1st and 2nd gear in 3rd it do little knocking and in 4th when accelarate it it starts knocking..

Help advice required plz

allmotor cd70?:eek:

SpoonMotorSports (SpoonMotorSports) 2012-03-09 12:39:47 +0500 #4

how do you guys control ignition timing? retard it a bit and add more fuel

FC (FC) 2012-03-09 14:17:56 +0500 #5

@spoon motors
bhae jaldi uth kar rply dein yesh all motor on a CD-70

Ignition timing is controled by a CDI unit... The CDI which i have Is a fully digital Stage 3 CDI unit. It has 1.65 Degree advance limit and + 800 - 1100 rpm... becuase in these bikes the engine is runing on fixed timing. Only Current timing varies and depends upon CDI UNIT.

And for adding more fuel... i m already using carburetor of CG-350

FC (FC) 2012-03-09 14:18:58 +0500 #6

M using HI OCTANE

Hv also changed the DRIVETRAIN PARTS

6 Disc Clutch kit with KEVLAR REINFORCED CLUTCH DISC for decreasing the final drive ratios

Transmission also changed
Old ratios were
1st-3.272, 2nd-1.937, 3rd-1.350, 4th-1.043

1st-2.623, 2nd-1.937, 3rd- 1.437, 4th- 1.300

bro try reducing your timing i dont know how your bike engines work but 1.65degrees or 1000degrees timing should vary depending on engine speed and load and it should be variable try using a step colder plugs

classickia (classickia) 2012-03-09 17:35:12 +0500 #15

change the carburetor altogether , which has more space in the float section,or adjust the float level to the maxium, dont' think this carburetor, serves the purpose, needs more and constant flow at high speed, at present its getting starved, also look into the exhaust.....if still no chang than let me know here .will not be available after 12 till 18 march

@spoon
bike runing fit till 2nd gear means PICK ACCELERATION is extra ordinary lkn in 3rd it starts knocking and in 4th gear end up in knocking i chckd out the piston condition it dont get any cieze or sum line or a hair line chckd out the head its all ok Valve spring + rocker all are ok... but cant figure out sum one said kay install a electronic fuel pump in ur bike is that will work ??? i got one LANCER electronic fuel pump vl it surve me ???

uptill now wht i end up wd the conclusion is she needs rich fuel but aint getting tht as when i changed the jets it improved alot following the threads of N20 and starletgt i chnged up the head gaskits but not find results

@classickia

@spoon
colder plugs means m using DENSO IRIDIUM IY24 8mm and 10mm tip iridium plug wht u suggest.. yar these are COLD plugs comparing to platinum as they got high melting points around 1100 or 1200 F

FC (FC) 2012-03-09 18:45:38 +0500 #18

@CLASSICKIA

Sorry yaar,
Abhi text parha hai tumhara.
Seriously yaar mujhe is alteration ke baaray main kuch nahi pata.
Never been into such kind of mods with bikes so cant debate much on this topic.
BTW Im still suprised on your level of mods.
Will be waiting for the pictures of the after market items installed.
