chain limiter
--------------------------------------------------------------------------------
i would like more info on what that chain limiter consists of and how it is used and attached.
i run a imca mod. and want to know if this would be a useful tuning tool.

my dw 8 is a touch tight going in and i would like it to turn better without getting off the gas as long, then once on the gas it gets sideways and to get out of the corner i need to slow to correct before bangin the loud peadal . i get good forword bit but no roll and poor side bite.
also i have trouble getting my left side up on the bars (i run a 4-z) 13" long top bar and 11" long lower bar on bc

bar angle is 22 degrees top and 8 degrees bottom.
with the z ink lower at 8degrees and top bar 5degrees down toward the rear

with me in the car the left side % is 54, should i move fuel cell closer to the right side to take off left%
rear is 58%, cross is 49.5%
springs are 600lf,650rf,225lr on bc / slider , 200rr on swingarm. shocks sre 4545lf,4555rf,3050lr,3030rr

just got a suggestion from gary clark at dirtworks and from another person to add 1/2" static rear steer and increase my rf spring rate by 50lb to a 700 lb.
to help it out, whats anyones feelings on that?

the only thing that really jumps out at me thats a little off is that you only have 49.5% crossweighht. maybe if you added a little cross it would help getting in the corner a little, which may fix the car from jumping sideways in the middle.
the tight in problem is most likely causing the loose problem in the middle. hope this helps.

if you raise the RF spring rate you will tighten the car into the corner more...try a 650 RF and a 700 LF spring or just swap your front springs the way you have them now.

If the track is slick and smooth, if it is rough you may want to go the first way i said otherwise it may bottom out on the tierods.

Car is bad fast as long as you can get it in and "up" on the RF aren't they??!!!

Is it tight just getting into the corner or as you turn into the middle?

Trailing the RR will help it turn all the way through the corner if it needs it.
Is the 30/50 an easy up or easy down shock. If its easy down id take it off and go to a straight valve or to an easy up.

yeah its fast when it hooks up, i put in the 650lf and 680 rf as gary told me and i also went with 1/2" static rear steer as he said too. i will scale tonight at 50.5 cross and i just wanted to ask , how much lr bite works best. i am also considering changing my rr spring to a 250 it all goes to work tomorrow night at the powecom speedzone.

paulickr - i have run from 200 LR to over 100 RR and each has their good and bad nights...if you are going with the stiffer RF spring I would say you would have somewhere around 40 -60 LR in it.

ran it last night with only 3-1/2" of rake in the shorty bar and had 650lf and 680 rf springs . also leading lr 1/2" as gary clark at dw recommended. the car practically steered itself through the corner (sideways of course) was a bit hard to get used to but felt better. it did seem to lack some forword bite. i just need to learn to stay on the gas when i am on the bars and it wont bobble coming out, it just felt like i was gonna loop it. then if i stayed with it , it just seemed to straighten out after the corner. seemed a lot better. may try a stiffer lr spring , maybe a 250lb.
