crustydemon Posted January 18, 2011 Report Share Posted January 18, 2011 As far as I know all Servals are for a 4 mill. Quote Link to comment Share on other sites More sharing options...

zachass9 Posted January 18, 2011 Report Share Posted January 18, 2011 Yes, there is a stock stroke version of the serval as well. Check with Andy @ M&M ATV with questions, he is building my stock stroke serval. Zac Quote Link to comment Share on other sites More sharing options...

gotta_goatsfast Posted January 19, 2011 Report Share Posted January 19, 2011 hell yea 10 mill serv!! Is this the motor you build when your banshee is required to pull trailers and race all in the same day? Quote Link to comment Share on other sites More sharing options...
SonOfSand Posted January 19, 2011 Report Share Posted January 19, 2011 what is +4mil mean? (sorry for newbies question) , would suggest me just a good trail port to stay on original crank? how much hp can we get out out of a trail porting? thanks The term "4mil" is in reference to how many inches over stock the stroke has been increased. 4 millimeters, 7 millimeters, and so on and so forth.

400sbc Posted January 19, 2011 Author Report Share Posted January 19, 2011 ok thanks for informations and what about the Vito's racing kit i saw that on sale on ebay ist that a good price? here is the link: http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&item=120651251025&ssPageName=ADME:X:RTQ:MOTORS:1123 Quote Link to comment Share on other sites More sharing options...

He missed the whole dune season. If you do a search you will find similar stories with Vito's. The best bang for the buck is the 4 mil stock cylinder build, Herr Juggs Racing is a site sponsor, and is one of the best at building banshees, do yourself a favor and call him.

Haha, you and me both brother. I chose the 4 mil cuz I already had a 58mm longrod crank... otherwise I'd have waited for a 10 mil. Wonder how crazy they'll get... maybe a Serval Super Cub with 72mm bore? Quote Link to comment Share on other sites More sharing options...
