hi gents. I run the china clone dominator pipe on my baja on a rovan 29,5cc with a 1mm stroke crank. to what extent can I chase timings with this pipe on both the intake side and exhaust side. we race on road oval tarmac. thanks gents.
 
done with my motor. now we have moved to level 4 lockdown, so no racing for us till 11 July. I kept the timing moderate on this built.
squish 0,300mm. intake 155* and exh 184*. motor for sure spool up much faster and much more responsive and I added a Walbro 257 carb.
