junkyarddog Posted May 8, 2016 Report Share Posted May 8, 2016 I'm new to driveline stuff but all I hear is good so fare I'm looking at the 421 kit and the 392 kit for the wife seems like a sweet deal at 800$ with Pistons and plate work done by Millennium Quote Link to comment Share on other sites More sharing options...
J-Madd Posted May 8, 2016 Report Share Posted May 8, 2016 Cubs are a more proven setup (only because they've been around so long) but I wouldn't hesitate at all on running Driveline cyls. Quote Link to comment Share on other sites More sharing options...
trickedcarbine Posted May 8, 2016 Report Share Posted May 8, 2016 Strictly drag, go cub. Dunes or trails, serval or driveline. 1 Quote Link to comment Share on other sites More sharing options...
jbooker82 Posted May 8, 2016 Report Share Posted May 8, 2016 Why not run both 421 setups? Quote Link to comment Share on other sites More sharing options...
junkyarddog Posted May 9, 2016 Author Report Share Posted May 9, 2016 I guess I should have made the listing (serval vs drivline) since Its dunner/trail bikes and drag for fun Quote Link to comment Share on other sites More sharing options...
junkyarddog Posted May 9, 2016 Author Report Share Posted May 9, 2016 Going to experiment on the wife's bike first here's has a fresh welded crank in it now only a season old so I'm thinking just slap on the 392 kit on her's 1 Quote Link to comment Share on other sites More sharing options...
trickedcarbine Posted May 9, 2016 Report Share Posted May 9, 2016 Makes sense. Quote Link to comment Share on other sites More sharing options...
junkyarddog Posted May 9, 2016 Author Report Share Posted May 9, 2016 I'm just wondering if the extra cost of serval is worth it? I have never owned anything but ported stockers, My motor is crankless and no top end so I have to get everything, does the 68mm domes even fit in a noss/pro design/ modquad style head?

trickedcarbine Posted May 9, 2016 Report Share Posted May 9, 2016 (edited) Yep. Should just be standard style domes. Yours just have one little tit that aligns the dome, correct? Just make sure you are ordering big bore domes if you are running a 68mm piston. Edited May 9, 2016 by trickedcarbine Quote Link to comment Share on other sites More sharing options...
junkyarddog Posted May 9, 2016 Author Report Share Posted May 9, 2016 I have noss head that uses pro design domes just making sure the big 68mm dome will fit in there Quote Link to comment Share on other sites More sharing options...
junkyarddog Posted May 9, 2016 Author Report Share Posted May 9, 2016 Is there anywhere I can get a better deal on this stuff? I'm pretty sure that's the cheapest crank deal Iv ever seen but hoping to findthe cylinders a little cheaper lol "hoping" Sent from my iPad using Tapatalk Quote Link to comment Share on other sites More sharing options...
gusto Posted May 9, 2016 Report Share Posted May 9, 2016 Buy the DRiveLine cylinders at 800 bucks, it's a no brainer. 421 as cast made 86 hp. Quote Link to comment Share on other sites More sharing options...
jbooker82 Posted May 9, 2016 Report Share Posted May 9, 2016 I'd buy the crank from Fast and have them put a better weld on it. Quote Link to comment Share on other sites More sharing options...
PaymentPlan Posted May 9, 2016 Report Share Posted May 9, 2016 (edited) If you buy from ebay, you should expect any help if something happens.Zilla, Why do some distibutors refer to their CP industries cylinders as serval cubs or cheetah cubs?

ClaudeMachining Posted May 9, 2016 Report Share Posted May 9, 2016 Zilla, Why do some distibutors refer to their CP industries cylinders as serval cubs or cheetah cubs? Same cyl, different timing/port Serval: 126/188 Cub : 130/197 My Driveline LP : 122/189 Quote Link to comment Share on other sites More sharing options...
