stock ports? WTF! t-6's are you kidding me!! paulturner midrange ON A DUNE MOTOR whatever!!
i have a 350cc stock motor with big ports ( drag port) 35mm pwk's modded reeds w 2 stage boyesens, very very true crank and welded light flywheel, +2 arms STOCK front shocks, big front smoothies, 11 paddle extreme straight paddle cool head, t-5's its an ABSOLUTE blast to ride its VERY VERY stable the stock axle with extended wheels is plenty wide enough and keeps the weight down, the 350cc motor if built corectly will run for a LONG time. this particular motor is about 3 1/2 years old and see's sand on almost a weekly basis, its dragged for fun 90% of the time it has plenty of bottom for trails and tree shots its a BLAST ont he big dunes.. i am also thinking of switching it to alky.. cooler motor and runs even harder..
the stock shocks with +2 arms end up being very soft intially and take lil bumps and hits great.
i run a +6 i dont just wheelie around but if i want to it will come up easily,,, but is plenty stable in long whoop sections at speeds more than 25mph. if you want easier wheelies a +4 or 2 over is great..
look at how YOU ride what do you like to do? step the sides of dunes? tight tight tight trails? long winding traisl at higher speeds? BIG dune jumpin? and go from there
EVERYONE that has rode the bike loves it its got plenty of zip to actually be fun if you want a boring bottom end grunt bike buy a fuggin 400ex.. and go get stuck in the tree shots witht he rest of those turds..
you obviously like the way the banshee blasts on power on the top end.. or you wouldnt have sold the boring 4 poke.. why kill it with turdy trail pipes or a woods setup in the dunes?
