they aren't to stiff the problem is they aren't stiff enough and your bottoming out. only solution is to get new front shocks and play with the compression on the rear.
If i was gonna spend the money avenger swing arms look sick and they look really well built. Other than that i really only know of laegers and LSR swing arms which are wonderful products if you wanna pay the money.
Awesome set of a-arms man but in the condition they are in your gonna have to lower the price down a bit. 300 may be a bit more respectable. not trying to tell you what to do its just my opinion.
I saw on your myspace that you had anodized ones would you be able to make a red one with just 1/4 holes just like my bumper? If so send me a message and a price.
I use DOT5 now and it seems to work great. Its not harsh at all compared to dot 3 and 4, you can actually get it on you skin and paint and it doesn't eat away at it. Other than that breaking performance didn't really change.
Give Hoosier or American racing tires a call and see what their tires are rated too. Im sure either one could do 120 since iv seen a few 1/8th mile guys using them up into the 120s.
For my mx setup right now i run 14/40 with 18s but thats even too short honestly. Id say 15/40 or 41 is the ticket for for 18s. Thats just me though you have to take into account what your motor can pull your weight the bikes weight. YOull just have to play around with it
In essence they are stock jugs on the outside whether or not they have been sleeved and ported. Its not that people don't want to believe you its that trinity doesnt do work like that to often if ever from all iv seen them do. All they try to do it say hey what type of riding do you do? you say trail... they say well hell you need a 18mil Cheeta motor for that. As for the head yes its a stage 4 trinity head... but its also referred to as a cool head. Also id love to say looks don't mean shit but on a banshee if i see a set of cheetas and i see a bike with stock cylinders id bet on the cheeta knowing if the outside is a cheeta the inside is just as good. So take a second to chill out and relax like the post before you were not trying to be asses to you we just found it hard to believe. If your a die hard banshee guy youve herd ever possiable bullshit story about i have this and this it goes this fast.... 120+ i think you get my point. other than that have a nice day
With mx its suspension before power in my opinion. Since you've got the motor almost done if you can spare the cash try and pick up a single carb setup to get even more low end grunt.
Ok not to be a douche but i must point out once again the seller is a liar unless im completely fucken retarded and cant tell the difference from stock jugs and cubs/cheetas. Like said before if its not a cub motor or a cheeta it would require a 12mm stroker to be 420. Ill post the pics from your profile so others can confirm this and see the bike. I have a feeling you've been dooped by some ass hat. sorry if im annoying you man i just hear this on endless posts and on alot of ebay auctions so it really gets me riled up.
