SLOPOKE21 Posted May 21, 2010 Report Posted May 21, 2010 i got a ported 4 mil cub on alky, 39 pwk's, shearer in frames, 17cc domes. i was trying to figure out what length swing arm to put on it. i am going to be mostly hill shooting and some occasional racing on a track, may even be on a paved track every now and then. i want something long enough so if i go bigger on my motor that i wont have to end up buying a new swinger. i was thinking like a +10 or +12 but i keep getting so many different answers i just wanted to see what some of you guys thought. i weigh about 225 and have 14-42 gearing.

I ran a +12 on my 4mil with 15-42 gearing 12 paddle extreem 72 inch rollout and dune raced it and track raced it,ran 4.17s, worked good,i weigh 235.Going to a 558 cheatah and having Stellar build me a +14 arched swinger.I just race mine at the hill on the dunes, so i don't do any tree shots on this bike.I went so long on the swinger because i can't run my wheelie bar at the dunes.

SLOPOKE21 Posted May 22, 2010 Author Report Posted May 22, 2010 those 12 paddles didnt hurt your top end any? i should have a pretty strong engine as i just got it ported and put on alky. i just dont want to buy a set of tires and a swingarm and them not be the right one. i am probably going to go with a +12 but i was hoping to get some more responses. nobody else out there has any more input?

No,the paddles worked good,you might be able to pull a 15 tooth up front, mine did no problem with a 2nd gear launch.I will probably go to a 14 paddle with the longer swinger and bigger motor.You could try posting it up in the drag forum maybe get more response.

camatv Posted May 23, 2010 Report Posted May 23, 2010 on flat drags id say +12 +14 and 12-14 paddle extreme possibly stagger'd sand condition will dictate paddle... tree shots and hill i'd lean more towards 8=10 length and 11-13 extreme's the shorter the arm the less paddle you will need the shorter the arm the more weight you will put on the tires B UT the more paddle you have the more power on top you will need to turn them also sand conditions..
