Serval is a great trail motor and cam at redline has some of the best results I have seen when it comes to porting. I got my 421 serval from FAST and it runs very very well. List of my mods can be seen on my profile
Compared to tapatalk it is, it's slower, you have to consistently zoom in and scroll left and right and zoom out and yeah... Tapatalk is much more efficient
I have had the EZ pull from fast and I am now going to the asv. I couldn't tell a big difference from stockto the EZ pull but I know a few ppl with asv and the are a hell of alot nicer
I have looked into them as well, I need to break down and do a dc conversion... Jd do you make a battery box that mounts where the overflow bottle was?
