Whats the difference between the Sportfire heads and the intruder heads??

The sportfire heads are marked: 440 2B -1
And the Intruders are marked: 440 2A -2

Could it be so that the Intruder has a higher compression ratio..?
If so it could be a good hop up for the sportfire....

If no one knows i will measure the cc....

Thanks!

Hi Magnus,

I don't have alot of technical info on the T-7 dual carb Instruder motor, other than seeing a few of them in person.

It is probable that Kawi ran a higher compression ratio, like the Invader head vs. the Liquifire head for example.

If you do CC one, please post the results, or even pic's of the head on your web page would be nice too.

Good Luck Magnus!
