Right now Ive got 30" backs on my bike, and I really like the backs, but there are a lot of people willing to trade 31" laws for a 30" backs and Im thinking about it. My questions is do the 31" laws put that much more stress on your bike than the 30s? I know both put a lot and there is a good chance of breaking something with the 30s, but does it increase that much more with the 31s? Also, I have the red EPI secondary, is that enough for 31s? Thanks for the help guys

The 30's and 31's are very similiar, i think you would be happy either way you went. The 31's do have a little more lug but I wouldn't consider it enough to say they will break more and if you were happy with your red secondary with 30's then you will be with the 31's too.

agreed wit bighead up there

I personally wouldn't get rid of my backs for 31's and I personally don't like the yellow spring but everyone has they're opinion on both.

i run yellow with my 31's. Seems to do the job.
We'll see how she does with the new pipe.

the only problem that might be an issue wit the yellow is the heat it produces from being tight on the belt. u can smell the belt "burning" alot. but we shall see how it does.

yep you can smell it when in a hole under load. We'll see how long that belt lasts.

Thanks for all the help guys. So I should be safe to go ahead and get the 31s? Im just going to pay alot more attention to the right thumb.

I like my 31's. You should too :)

I was looking at your thread on heating the plastics to make them fit, is that still needed if I am running the IRS offset rims and a 2" lift?
 
#15 ·
probably so. They're large tires. If you have to though it doesnt take very long and u cant even tell you did it later on.
Mine still grabbed the front bash plate and ripped it right off. :D
i like how it looks without it I think. now I need a HL bumper and a new front bash plate.

Guess spacers may be in the future, I'll have to see once I get them on. Im not to worried about the footwells are anything cause they can easily be trimmed.
 
#16 ·
From that story I'm not so sure I believe the tires just "ripped it off" lol.:naughty:
Or is that the story you had to tell somone to get the new HL parts.

I'm telling you, i was just riding and they came right off.

I'm his witness for it ripping it right off we were riding and kept hearing SLAPPA SLAPPA SLAPPA every time he turned hard (yes, that IS the sound it was making:D) And before we new it the front plastic bash plate was folded under draggin the ground.

yep :( now its a cut off piece of junk laying on the floor of my garage. In fact it's still in the same spot it was when you were here, Jon. I'm a tidy guy :)

one of our guys that ride in our group bought a new tyrex and put 30 silver backs on and broke one of his axles the first time out

That has to suck major!

yeah i guess he did :haha: prob had his foot in it when it happened !! LOL I destroyed my right front axle about a week after switching to the 650 from the old 400. had to learn to be easy on the throttle :haha::haha: kawie V-twins love to break ****:agreed:regardless of what its on
 
#24 ·
tends to happen when you put little too much throttle to it and catch traction

Yea, I've broken 3 gorilla axles on the back and still have 2 1/2 months of warranty left. I'm moving those to the wife's bike and I have a set of turner's sitting there ready to go in. Gotta love having a warranty, just don't think I'll need it with the turners. I'll definitly give them a full test this summer.
 
#27 ·
Turners are THICK
 
#33 ·
To me the difference is easy....I'm only an hour from Gorilla in W. Monroe, LA. lol No shipping necessary!!
 
#29 ·
All the bending, spacers, and clearance issues made me decide to just get a new set of 30" backs. Thank goodness for WARRANTY, lol
