Johnny_3_Tears Posted March 4, 2009 Report Share Posted March 4, 2009 Hey guys, Im building a duner... I am looking into the 404 re sleeve setup from Vitos (comes with sleeves pistons bearings yadda yadda) My question is, is it real hard to re sleeve the cylinders? i have a pretty decent understanding of how to take this motor apart and put it back together..(ive rebuilt my banshee, a handful of snowmobiles...) but I've never re-sleeved anything. Now i understand that after the sleeves are in they will need to be bored to fit the piston. No big deal... But how hard is it to re sleeve? Thanks for your help!

shanYE west Posted March 4, 2009 Report Share Posted March 4, 2009 The big bore sleeve will not get you anymore power.. By increasing the bore they're further choke down the tranfers.. Best bet would be a good port job. Or.. If you go with the big bore sleeves.. the trasfers need to be welded and ported to make and real gains. But it gets a bit pricey when you have to weld stuff up. Quote Link to comment Share on other sites More sharing options...

Right on thanks, so you think that a 4mm stock bore stroker would make more power than the vitos 404 resleeve... either way the cylinders are going in for a port job...

flyhighprerunner Posted March 4, 2009 Report Share Posted March 4, 2009 I think you would be alot happier with a port job anyways but thats just me. Quote Link to comment Share on other sites More sharing options...
Johnny_3_Tears Posted March 4, 2009 Author Report Share Posted March 4, 2009 I think you would be alot happier with a port job anyways but thats just me. With just a port job? or with a 4mm and a port? Or a 404 with a port? What port would you recommend, i do mostly dune riding, some (very rare) trail riding.

The cub is king of the drags but not every one builds a drag engine. Yea you could have built a cub for way cheaper than a big bore stock cylinder 4 mill but if the power is not where you want it why build it. josh Quote Link to comment Share on other sites More sharing options...

But it gets a bit pricey when you have to weld stuff up. My transfers still have some aluminum left in them. I think it depends on what sleeves you have put in. I can see the big 68mm plus sleevess needing some work Here are some pics of the transfers. The sleeves are just 66mm to 68mm bore. Quote Link to comment Share on other sites More sharing options...
tony cub Posted March 5, 2009 Report Share Posted March 5, 2009 my trail bike is a 10 mill 72mm cub,so the bigger the better for me..at the end of the day you can spend over 1k resleveing and welding for a 72mm bore..i know thats not what he is doing,but why spend all that cash and still not compair to a cub..thats my .02..

jbooker82 Posted March 5, 2009 Report Share Posted March 5, 2009 A cub is not a TRUE trail machine. And Fire roads do not count as trails. Your right a resleeved stock cylinder will not compair to the Top End power a cub has. Just like I said above. The cub is king of the drags but not every one builds a drag engine. Yea you could have built a cub for way cheaper than a big bore stock cylinder 4 mill but if the power is not where you want it why build it.

tony cub Posted March 5, 2009 Report Share Posted March 5, 2009 (edited) if you want a "trail bike" just bore out your stockers if possible..the guy is looking for power hence the big bore kit..get a cub your going to be much happier.. :thumbsup: Edited March 5, 2009 by tony cub Quote Link to comment Share on other sites More sharing options...

Johnny_3_Tears Posted March 5, 2009 Author Report Share Posted March 5, 2009 he never stated his riding style. i was just giving him some options. Yeah, really I'm just a dune rider, my friend also has an track in his field that we goof around on. But the majority of my riding is in the dunes. (I would say 75% Dunes and 25% track) I wasnt looking to do a 4mm big bore stroker... i was only looking at one or the other. a big bore or a 4mm kit. im just lookin for a little more power to carry my big ass around. im 6'1" 230...hehe I think im goin with the 4mm i found one for a great price with a spacer and pistons for 300. Craigs list is the shit. And i get my port work done for a 50 bucks case of beer, its a hook up through work :-) He works for DeMaegd Motorsports, its a local baja racing team. BTW Jbooker, i like your jugs :biggrin: Quote Link to comment Share on other sites More sharing options...
