I have a 2001 rocket and just cant get the thing to work. I was wondering if i should have my rr clamped or not. Was wondering what that would do. This thing is very seldom right. Its just a mess most of the time. Cant seem to hit the right setup. Any help? Thx!!!

i would say no. some guys are messing around with the rr clamped up but behind the axle.
i think you would be best to just run a standard lr behind setup (rocket setup manual). we tried and tried to make our rocket work with rocket's "high wedge setup" but i think you need to be a way better driver than me, with a heap of horsepower to make that type of setup work. we have since switched to rocket's "low wedge setup" and have found that quite user friendly.
what problems are you having? and what is your current setup?

First of all rocket thx for the reply. I think u hit the nail on the head with the high wedge setup. The problem were havin most is being able to change with the track.As a rule most tracks go slick through the night. Ours dont.most of the time.They gotta big old water truck.So most times it dont get that slick.Took a yr to figure that out. So were gonna try low wedge ( rockets 2004 edition) and try to tune from there. It looks like we can work our way into the low wedge/big rr spring if we have to without a whole lot of takin springs off and on (ie- sping rubbers) and wedge adjustments. Just gotta do the math in the shop and write it all done. If this sounds like the way to go please let me know .Any help is appreciated thx again.

We ran a High Wedge setup in our Rocket and it worked great if you could keep in the gas and only used the brakes to put it into the corner. When I had to get out of it quick the car got really pushy to the right and would almost throw us out of the track.

cessnaflyboy,

I run the Low Wedge Big RR about 80% of the time. When I'm not on that, I'm on the STD. Low Wedge. Very seldom do I run the High Wedge, usually only at very big momentum tracks. The LW big RR set-up is very user friendly, and quite comfortable to drive. If your running on really hooked up, hammer down tracks that are full of holes, the Double Clamp set-up works quite well. It will run with most swing-arm car's through the holes.

I'll be honest with you though. Most complaints about Rockets not working, are a result of how they are being driven. Not saying that your driving wrong, but if your used to a different brand of car, the Rocket takes some getting used to. What I found out when going from my GRT to the Rocket was the following. In my GRT's, as you would enter the corner you would wait for the car to scotch, then you knew it was time to pick up the throttle. You can't wait for this in a Rocket! If you wait on a Rocket to scotch up, you'll be waiting forever. This will make you feel loose as **** getting in, all the time wanting more side bite. If your waiting on the car to scotch, then your going to get a throttle push when you finally do pick up the gas. So don't wait on the car, driver her in, and pick up the throttle. Rockets will feel very loose getting in, until you pick up the throttle, then she will tighten up and drive. This is just what I've found out for myself.

we index regularly on the left side. usually just chasing bite coming off the corner. it does work well but you have to learn to drive a little different when indexed. as you get out of the throttle to enter the turn, the chassis sort of settles down (comes down) which unwinds (de-indexes) very quickly which tends to loosen our car just for a second as you get out of the throttle. The first couple of times i looped it, but once i learned to keep the car under me, nice and straight at the corner, it worked well. thats what i have found anyway.

I too have a new Rocket and suffering through the same things and noticed that the throttle will tighten me up getting in. But here is one of my problems. Running nose to tell say behind a GRT. How to you keep from knocking there quaters off when there not gasing up as soon as you are? If I got a cushion or a big wide corner..I love this car, If I have to run the bottom and stop and go, I ain't real sure about her *grin*

No doubt bizkit!!!!! Running behind a GRT or Mastersbuilt is a little frustrating. I've had the problem your describing, your off the gas for them which really tightens you up in the middle. Then you have to break the car loose to get off the corner, which still relegates you to running behind them and burning up the RR tire. Traffic has been an issue for me in this new car as well, and I've replaced a few RF fenders along the way...LOL! If there is more than one groove however............... One thing is for sure, you can't just ride in line in one of these car's. So I'm really not looking forward to running at the one lane, little, dry, ****py track that we have to go to this Saturday!!! I guess I'll just have to qualify good...lol!

Bust'er on the pole my friend. You running the purple stuff, or have you gone the AMERICAN way *grin*

On a side note. I'm going to start playing with the double RR stuff in the slick one lane tracks. I'm thinking it might just tighten us up enough getting in or short corners. Just hoping I don't loose this great fwd bite

Had to ditch the purple tread, and go the American way. When the Americans are 3/10's to 5/10's faster, I'm left with little choice ;-) I must say though, they hold up pretty well! There has been a lot of purple "deals" getting lost around here......know what I mean ? ;-))

Let me know about the double RR set-up. I'd like to try it on my Rocket, just haven't had the nad's enough to do so.

Will do my man, But it want be for a week or 2. Running big cushion tracks the next few weeks and this baby on the traditional low wedge deal makes me real happy.

I will tell you what I learned last weekend that helped more than the 250 RR did. Evening up the 4 links 18" tops and 16 bottoms, actually ran the 16" top on the LR and kept everything else the same. Also if you need it I got Jimmy Ownes set up he used when he was with that team Scott Sexton is with now. Just PM or email me at khanvey@mmm.com and I'll pass it along

Thanks, I'll be curious to find out how she runs with the double spring.

I've tried the short LR top rod, and the long LR bottom rod once. It probably wasn't a fare test, and I did not care for it too much. I might try it again this weekend though. I also tried the 18-1/4 LR top with the 18" LR bottom in the 6th hole up. Once again it wasn't the best place to try this at, but it felt pretty good. I feel like it would work great at a small, slick track with slow corner speed.

I'll email you about the other set-up you mentioned.

How did you do in the slick one lane track this weekend?

I drew a bad number for qualifying, and qualified bad............real bad! The car was actually pretty good, but the driver was being too careful. Started 17th, drove around in circles with a good car and nowhere to pass for 5-6 laps, and cut a break line. Didn't matter much though, the race was pretty much over after qualifying.

Now I'm leaving for Ukraine on business today, and when I get home it will be time for 2 real race tracks......Thunder Valley in Lawndale, NC and Wythe Raceway in Rural Retreat, VA. I'll be able to take off the vacuum secondary carb., and let her breath a little.

I'll catch up with you when I get back from Europe. Hope you had a good weekend!!

Man I had some bad luck..was racing for 2nd and I'm not sure what happened but I believe the battery got up in the decking, and she just went dead, lost all power.
Saturday night we took our open motor car (GRT) to GreenValley 4/10ths track thats pretty fast. Qualified 5th and first lap, darn power steering or rack messed up. So I didn't finish a race all weekend. Have fun in Europe!!
