[QUOTE="gwunter, post: 560431, member: 9742"] On the subject of gear trains. I have looked into this a bit. It seems that some suppliers offer different options. One company offers to replace all 3 gears(cam, crank, pump) while HMax, I believe, only offers an injection pump gear; which mates with cam gear. I would think that if it were a routine issue of breaking the cam nose off HMax would not offer just a pump gear. Once again with just needing to buy a pump gear, for a street setup, I think the HMax would be the way to go. Running off the HPOP gear would almost create a weak point. Perhaps another crank gear could be utilized, in place of the HPOP gear. This would make going from there to proper pump speed easier math, for a hilljack like me that is. From there one could source a more generic 2to1 raito set of gears. JMHO [/QUOTE]
