HOWEVER, I've seen these slightly different ones selling for under $500.....

first one mentioned has multi spark (inbuilt spark control) and rev limiter

second one is just timing retard no spark unit

so for extra 2-300 i can get spark unit and timing retard in one unit

cheers for the advice

[Taz_Rx]

Ahh that explains the price diff. Sorry I didn't really read the specs.

Deffinately get the first one then. :)

Similar...yet different. That Jaycar kit isn't a CDi unit to start with. Plus it doesn't have a vacuum port for an internal map sensor or equivalent so it can't retard timing in relation to boost pressure.

[Damon550]

i was thinking that it didn't have any sort of map sensor

[Felix]

That bike is a beast.

 

You will find that the jaycar kit can use a map sensor if you do a little research.

[4k trike]

how the hell did you do a head gasket so quickly?

 

did you wear the engine in without the charger hooked up?

[4k trike]

hope gasket was faulty mite have had air lock in it i did notice gasket dident have all holes for water to flow through opened up got any sugestions?

ran enjin for 1 hour nateraly asperated

[ae824ate]

A new head gasket shouldnt fail that quick. Have you got a temp guage hooked up? Seen your videos but don't remember. Was it run in and on boost at the time? Love your work mate. Also, how was the engine worn in? How was it driven? Cheers.

Blowing a gasket that quick isn't all that suprising..... it means you're not pulling enough timing out of it on boost. The HG is always the first thing to fail. Makke sure you have no more than about 25-30* of timing while on boost. Or start on 20 and slowly increase it.

 

Oh and the head gasket doesn't have holes in the FRONT of it to try and promote water flow through the back of the head. Otherwise the water would take the path of less resistance and just loop around the front of the motor between the water pump and thermostat housing. :yes:
