CFH87 Posted November 19, 2010 Report Share Posted November 19, 2010 For a while now I've been thinking of rebuilding the motor on my banshee. My main question is this is it really worth it to rebuild? Im kinda leaning towards getting it ported and raise the compression. Only reason I ask is because my cousin is killing me with his cr250 and he has a fresh build. I will go with the following things. Wesico pistons weld stock crank new bearings dune port from fast cool head 28mm carbs rocket r2 pipes With this set up should I be able to keep up a little better? Thats my main worry if not I hate to say it but I might go to the dark side... Quote Link to comment Share on other sites More sharing options...
bansheesrtoys Posted November 19, 2010 Report Share Posted November 19, 2010 also try to gearing it different. and instead of welding your stock crank go with a +4 and have the jugs ported to match with a coolhead a specail cut domes. and then hell yeah u should.

I had Wildcard do an Aggressive Dune Port on my stock 350... and it makes a huge differance. And here in Utah at 5000FT, anything helps But a 4mil would be sick for sure.

CFH87 Posted November 19, 2010 Author Report Share Posted November 19, 2010 How would the power be on a 4 mill I'm worried about how much gas it'll drink Quote Link to comment Share on other sites More sharing options...
06specialedition Posted November 19, 2010 Report Share Posted November 19, 2010 How would the power be on a 4 mill I'm worried about how much gas it'll drink My friend has some of the same mods as me on his banshee, except his isn't ported, vforce3's, duel pingle...etc. And my bike used ALOT more gas than his. But its well worth the power gains Quote Link to comment Share on other sites More sharing options...
CFH87 Posted November 19, 2010 Author Report Share Posted November 19, 2010 Would it make a good trail bike? And id imagine ill need atleast a +2 swingarm to keep it down Quote Link to comment Share on other sites More sharing options...

jbooker82 Posted November 19, 2010 Report Share Posted November 19, 2010 Would it make a good trail bike? And id imagine ill need atleast a +2 swingarm to keep it down It would make a great trail bike. The 4mill doesnt add a bunch of top end on its own. It gains you a stronger midrange. Wich in turn most people exchange for more top end by going with a more agressive port job and pipes. So you still end up with a stronger or as strong of a midrange with more top end.

Jereme6655 Posted November 19, 2010 Report Share Posted November 19, 2010 yes rebuilding is worth it if your low on compression.......but just getting it ported is not going to raise your compression. Hook up with a sponsor on here....they all do really good work...and have them port your cylinders and bore/hone out your cylinders for the rebuild. Then make sure you get that thing jetted right and give it hell against your cousin (after break-in of course) Quote Link to comment Share on other sites More sharing options...
midlifecrisis Posted November 19, 2010 Report Share Posted November 19, 2010 Things to start with pipes, port to match the pipes & advance the timing. Forget going long distances on your bike once you start modding it heavily. Especially if you are doing carbs as well. These girls are heavy on the fuel consumption as it is, even with stock carbs. If you want to go for the day trail riding, hide a few jerry cans of premix along the way, for peice of mind. Quote Link to comment Share on other sites More sharing options...
