Is the sparks racing head a very good bore.

 

That right there is a question I am not qualified to answer.[img]i/expressions/face-icon-small-wink.gif[/img]

Anyone else?[img]i/expressions/face-icon-small-happy.gif[/img]

 

What is that supposed to mean.

 

It means I don't know the answer, the way the question was stated.

Nothing more......[img]i/expressions/face-icon-small-wink.gif[/img]

 

Is it a good big bore

 

kl Sparks does not makes any thing for Bombardier

 

I want it for a z not a bombardiar.

 

Sparks is a very good engine builder. They make some strong running Raptors and 450's. As for the z-400. Im not sure. Havent heard or seen any Sparks z's.

 

I haven't been able to get any of the Sparks big bores to work on my DS either. Seemed like none of the holes would line up! I tried every kit they had and none of them would fit they all seemed really small... like my piston would not fit in the jug at all. I don't know who is running the Sparks R&D over there for Bomb's but did they know these things are 650cc from the factory. They must be making a displacement reducer for the track... I think AMA rules limit them to 450cc. I don't know...That is just my experience... maybe try the Suzuki forum they might have more experience with this type thing.

 

Excellent suggestion Fatholly! Excellent suggestion!
