i have also heard from someone on another site that you can buy these motors already modded, yet i have never seen it advertised anywhere.

Have you tried different tuned-pipes? A JP-2 seems to really wake up the top end on 3 port motors...

i have been running the VG for 3 gallons now, all i can say for 150 dollars, its worth it.

its an excellent small to medium sized track motor, for larger tracks, its stretching it

i ran this motor out here locally, i couldnt believe the power it had. i took it out to KZ and raced twice with it, and it seems too much of a track for this mill. im sure i can maintain, but its best to buy a motor that is more suited for such applications.

none the less i am happy to have this motor in my pit box or at races. at KZ, i was pitting at the 8 minute mark EASY, for it to get excellent milage at one of the biggest tracks in cali, gatta say something.

i will be racing with a different mill at KZ for now on, but if i ever hit the smaller tracks, my VG is coming right out!

the JP-2 works great with this motor, but i am currently using my Mugen 1005 pipe with a long header just because i have it. but the JP-2 seems to be the best way to go with this motor.

if you have the Novarossi 086 pipe, that also works well, the Sirio 2013 with a long header also ripped and the OS 2050.

i forgot to add, i have been running this motor in my Mugen MBX5T.

if it last me 2 to 3 more gallons, its well worth the buy. if it last longer than that, thats excellent.

what's the difference between a jp-2 pipe and a os 2050 pipe? for that matter, what's the difference between an os 2050 and an os 2060?
