Abe Posted March 24, 2013 Report Share Posted March 24, 2013 Ok guys I am building a 421 serval with supporting mods such as inframe drag pipes and 35 pwk carbs advanced timing etc. so predicting 75 + hp as cast for now and later on once I have the entire bike as I want it I will probably do a serval style port which would bump up into the 85 + hp range. The bike will be used as a trail/play bike that will need to perform a little of all types of riding, hill climbs , buddy drags, and just about anything u can think to throw at it. My ? Is a +4 or +6 swingarm gonna be the better match. Will probably run 22 in tires and I'm a heavy rider so traction should not be an issue with either arm.

Abe Posted March 24, 2013 Author Report Share Posted March 24, 2013 I really like the looks of the +6 but haven't rode anything bigger than a +4 and was worried about the the ride ability since I'm not fortunate enough to own more than one bike so it must do it all Quote Link to comment Share on other sites More sharing options...
5150banshee Posted March 24, 2013 Report Share Posted March 24, 2013 I run a 6 on mine and I'm able to dune it just fine and its there when I wanna hit the hill. Sent using Tapatalk Quote Link to comment Share on other sites More sharing options...
trickedcarbine Posted March 24, 2013 Report Share Posted March 24, 2013 If it were me, I would just leave it stock length, but then again I'm the idiot running 80 HP on a -2 swinger. Btw my DM will be in the same chassis. If you must go longer, just remember you said you wanted it to be trailable. The longer you get the harder it is to turn. But you said you wanna climb with it so I guess the +4 is a happy medium. Just make sure to pony up for a round house swinger though.

rjdgriff Posted March 24, 2013 Report Share Posted March 24, 2013 My 421 serval has a +4 swinger and it works great... I had a +6 on it for awhile but I really like the +4 in the trails Quote Link to comment Share on other sites More sharing options...

locogato11283 Posted March 25, 2013 Report Share Posted March 25, 2013 A DM with a -2???? Why? For riding in circles. Quote Link to comment Share on other sites More sharing options...
sprinklerman Posted March 25, 2013 Report Share Posted March 25, 2013 Either way, id suggest bugeting a little money to get the rear shock setup for it. It DOES make a difference. Id reccomend MattSCSS ,even though he's a prune-picker. Quote Link to comment Share on other sites More sharing options...

If you don't like it we might be able to work out a trade on my +4 Quote Link to comment Share on other sites More sharing options...

If you don't like it we might be able to work out a trade on my +4 That sounds like a good idea Quote Link to comment Share on other sites More sharing options...
