Decent Ignition Coil / Spark Plug leads

[gros21]

Well I've hot 2 mini bikes just wondering if coils/make that much difference. Both will be running pitster 160ho with a bbk.

Do performance coils make much of a difference also what about Irridium spark plugs?
Will bike require a retune after these mods.

I just want to know if I'm spending $100ish per bike it's money well spent.

What do u guys run?

i have a china Performance coil, it gives a bigger spark than the standard coil.
i also run a Splitfire lead, which helps by keeping the spark at it's biggest, they have a capacitor built into the spacer on the lead that stores the energy and releases it at it's peak.
you can certainly hear/see the difference in the spark intensity too
and i run an NGK Irridium Spark Plug too, CR7HIX
those 3 parts cost me under $35 for the lot delivered.

a lot of engines will need a retune after upgrading your ignition coil,lead and plug

yeh, my 125 needed the mixture richened slightly, after putting on my china splitfire lead, but there was a definate improvement in performance, it was a worthwhile mod IMO

A coil like this?

I've ordered some split fire leads.
Spark plugs I haven't found yet.

How easy is it to retune a carby?

tuning the carb would be easy enough, it would most likely be a mixture screw adjustment, i highly doubt you'd have to change jets. i would say just screw your mixture screw in 1.5 turns, and see how it is with the new coil/lead

I thought CR7HIX was the one I would be needing?

That coil would be fine though?

i think your right on the plug, lol im a tad tired..
as for the coil i would not be too sure, i've never used a chinese performance coils, although a few members on here have used performance coils from takegawa, chp, etc, and they have said they are a big improvement from stock. heres a link for a cr7hix lol
