odaen Posted March 3, 2006 Report Share Posted March 3, 2006 porting....some timing advance, compression all come to mind Quote Link to comment Share on other sites More sharing options...
supercoop Posted March 3, 2006 Author Report Share Posted March 3, 2006 how much would these cost me? porting....some timing advance, compression all come to mind 481560[/snapback] Quote Link to comment Share on other sites More sharing options...
odaen Posted March 3, 2006 Report Share Posted March 3, 2006 35 for the timing plate 50ish for surfacing the head for compression 300ish + Pistons for porting With all of those, you'll have a completely different motor Quote Link to comment Share on other sites More sharing options...
. Posted March 3, 2006 Report Share Posted March 3, 2006 It's all about the pipes.....I'd recommend LRD's if you can find them, pretty much wont find a better mx pipe. higher compression, dual stage reeds or vforce's is a biggy, a little bit of porting and some timing will go a long way.

odaen Posted March 3, 2006 Report Share Posted March 3, 2006 he has DMC aliens in his sig, heard they were a good mx pipe, so I just ignored pipes altogether. Quote Link to comment Share on other sites More sharing options...
Chad Posted March 3, 2006 Report Share Posted March 3, 2006 2-1 carb, they are expensive new, but you can find used ones for about 2-300 Quote Link to comment Share on other sites More sharing options...
supercoop Posted March 3, 2006 Author Report Share Posted March 3, 2006 thanks for the replies so far. I have been looking at the 404 Big Bore sleeve kit at Vito's Performance at http://www.vitosperformance.net/BANSHEE.HT...%20SLEEVE%20KIT for $469.95 would this be good for me or can you recommend anything else?

You need a PORT JOB! Plain and simple. You're other option would be finding some RZ350 jugs but that might be too much trouble than it's worth for what you want. Search the forum for "MX port" and you should come up with days worth of reading. Find a reputable builder and go from there. A 4mm portjob on stock cylinders would be plenty of motor for MX. Suspension is what I would be worried about... Quote Link to comment Share on other sites More sharing options...
rocketboy Posted March 4, 2006 Report Share Posted March 4, 2006 like Odaen said ... higher static compression , midrange porting ,advance the ignition timing totally different bike Quote Link to comment Share on other sites More sharing options...
Wicked98Shee Posted March 4, 2006 Report Share Posted March 4, 2006 porting will give ya the best BANG for the buck .. toss in a adj. timing plate and get head milled ..... and then its like Odaen said she'll be a different animal Quote Link to comment Share on other sites More sharing options...

V-force reeds, 30mm carbs and a set of Rocket pipes. I was running PTR mids which ran the same down low on these jugs and the Rockets really let it rev high. I ride trails all day long in 3rd gear. I rarely shift and it pulls hard as hell from idle up. Quote Link to comment Share on other sites More sharing options...
macgillivary Posted March 4, 2006 Report Share Posted March 4, 2006 Your gonna want a good set of rear tires too, you can have all the power in the world but if you cant hook up its useless power, shorten up that swingarm, it can be done by yourself do a search, 18's on the back for quick acceleration, no reason to run big tires building an mx banshee gets really expensive, trust me i built a budget one and its not much of a budget once you get into it, thousands of dollars to make it competitive Quote Link to comment Share on other sites More sharing options...
