Ask yourself, do you want it to be more stable (+ ARMS) or do you want to keep the front end down (SWINGARM) you got some mods so i would go with swingarm but do you take round house or OEM style? if you have the cash go round.
I just noticed your info in your sig. if it boggs at half throttle i would raise the needles 1 clip. if its good keep it and just do a plug chop if its better but not good go up one more. if its worse go down with the needle. got it?
The main jets are for 3/4 to wide open throttle. you need to do a plug chop for that. if it bogs at half throttle i would try raising your needles one clip and see what happens. only do one thing at a time. if you do more you wont know what you did to make it better or worse.
where are you from and what are your mods? hope thats not oem carbs your jetting with a 152M and 45P. if so i would have to say your lean hahaha. ok Keihin carbs and what else you got?
If you pulled a metal chunk out of your oil that resembles a piston skirt and its not the ears on you clutch basket your bike needs more then a piston / bore job. you defiantly need new cases.
yfz front calipers.
honda 250r rear axle bearings/seals.
300ex front shocks to lower it.
R6 rear shock to lower it but not sure what years.
worrier / blaster front shocks.
lt250r front shocks and rear brake caliper. brake pads are also the same.
I believe tri-z and worrier axle and hubs are the same but not sure.
Thats what some look for and you have some that look for that 2mm ring on the bottom of the porcelain. i would say for the most part your good. a little rich wont hurt a thing.
you lost me with the (and i mean cold.) i`m not sure about that cold but i would change that plug and see what happens. bogging at 3/4 could be from running lean or rich. did you look into doing a plug chop? i`m just lost on the cold air part.
The 450 front end will fit on a banshee but you need to trim some off the lower arms and make spacers for the opposite side. the shocks need to be ground up a bit on the lower part of the shock to fit. them mods are easy but i`m not sure where to get the spacers. it you have or have access to a lathe with some commonsense its a easy job.
What parts do you need?
