STOCK SPECIFICATIONS: 74mm
BORE X 58mm STROKE 9.5:1 COMPRESSION
Please note: We have not fully tested these products. We developed them for a
race effort, which never went past the development stage. We have checked
clearance on all parts, so we know components will install properly. We have not
run any dyno tests or other "real world" setups with these parts.
Some
customers have tested and like the results they get from this bore kit and cam,
so we are offering them, just realize you will need to figure out your own
jetting and tuning specifications.
