Best pipe for 85-86 250r?

[250rmanfmf]

Well, I am getting ready to upgrade my 250r. First thing I want to change is my pipe. I have a fmf now but know there are better ones out there. I have heard about paul turner pipes and esr pipes. Any suggestions on which pipe performs best? Most likey the trike will be a straight drag racer in the future so a pipe good for topend.

Thanks
Tyler

Allot of it is personal preference. Some guys like it to hit hard, some like a smoother transition....

Seems like the PT Hi-Rev pipe is popular.

I know DEEPA has tried quite a few pipes and they all acted different. When he comes back from his 3WW vacation, maybe he'll chime in.

KASEY must have some thoughts on this too as he has probably owned a dozen or so different 250R expansion chambers,

I'll bet MOSH has tried a few also, or at least rode 250R's with different ones.

Paul turner high rev !!!

[KASEY]

if you want an inframe pipe that won't get you into the real fast reahlm you will have to buy a out of frame if you really want to go faster.... the pipe is a small part of going fast,, and if you have deeeep pockets and want to go real fast a hand made drag pipe will be your choice ,, a paul turner hi rev pipe will carry you along way along the drag race path,,, but you will know when its time for a oof pipe, duner on here built a pretty fast 370 and was using a pt hi rev for a while , but he had to move on to go faster too,,

If you plan on using it for the dunes hands down the ESR atc pipe, also owned the Paul Turner high rev pipe for my atc but the ESR was hands down night and day difference at Glamis. I also had both piped dyno tuned by Kenz Cycle Tech and dyno numbers were better with ESR pipe all accross the RPM range.

[DixiePlowboy]

Marty, are you referring to the ESR ATC-5 pipe?

Am I understanding that the ESR also made more high RPM power than the PT Hi-Rev? If so, roughly how many more RPM?

Either way, great info having a dyno-backed review/comparison. Thanks for the input!

[250rmanfmf]

Yea, this is a sand dune racer, this trike doesnt see dirt! I will be doing some big time cylinder work to the motor when she gets tired. Just wanted to go with the best pipe possible.

Thanks

My wifes R runs a ESR 5 pipe on a 20 over, non ported cylinder, with a PJ36 carb and plus 3 swingarm with 13-38 gearing.

MY R is 50 over, with a PWK 38 mil carb,V Force 3 cage, CR head gasket, with a heavily ported cylinder on 50-50 race gas with a plus 3 swinger and 13-38 gearing.

We have drag raced repeatedly, and I will tell you this. I eat her alive out of the hole. That ESR pipe works so well, that Stock engine of hers, will catch me and run 1-2 feet behind me all day long and never lose any ground.

My conclusion on these 4 pipes I have ran and tested is this, in this order....

(1) The ESR is hands down probably the best pipe made for the R, if you want a nice mellow transistion of power, and expandable power potential. In other words, if you are running a stock R, and plan on engine mods in the future, this pipe will suit a wide variety of builds. Plus, it is the most heavily well built pipe of all of them. It is thick and strong, with good chrome,and only minor fitment issues.

(2) The PT Hi Rev. This pipe makes great power on built engines, but I feel may lack power on a stock engine. It likes to run hard,and it will take a rider with a heavy thumb to use it to it's potential. The snappy on-off feel of this pipe may not suit some riders, that do not prefer that un-expected Punch while riding. However, I have never seen these pipes fit worth a crap. You will have a harder time mounting the PT pipes.I would still run one on a built motor, if I found one for a great price.But for what poeple want for them used no less, I will spend the extra 75-100 bucks and grab the ESR New.

(3) The FMF. This is a good pipe for stock or even mild built engines. They are affordable, and they fit good. The chrome is Ok on them, but not as nice as the ESR. They work well in all facets of the powerband, and do not have a undesired hit to them when they come on the pipe.However, I do feel that they will hinder a well built or ported R engine.

(4) The DG..Like I said before, this pipe is a better replacement than OEM for a stockish engine. For the guy on a budget, that does not need more Hi RPM power, it will work good for you. It is a great woods pipe and the fit is usually decent, but the build quality is flimsy, and thin, and will wear out after a few seasons. They also tend to be the leakier of the pipes at the jug.


I am not a expert, and I have not tested these back to back on the same machines. I am just offering my opinion of what I have felt.
If you want the best inframe pipe for a R, that has expandable power, rugged built, and great appearence, the ESR is the only way to go.
***However, if you run the ESR on a stock engine, be prepared to use the clucth alot while down low in the RPM range, and also be ready to stir the gearbox some, as you will have to put in some extra effort to make this pipe work down low on a stock engine vs. a DG or FMF Fatty.****

And new for new, I think the ESR is the same price as the hi-rev, if not cheaper on the chrome models.
Hope that helps.

Interesting that your impression of the DG and FMF is 180-degrees of mine. My boy's R is wearing an FMF and mine came to me with a DG. Both are otherwise stock. I felt like the FMF was a weaker pipe than the DG and that the DG had a bit more rev than the FMF. Maybe some other differences in machine tune influencing the different impressions we have.

I had a PT hi-rev back several years ago and I agree on it being more of a true rev pipe. I actually like the hit and prefer it, BUT.....you need to work for Eddie Sanders...lol, because you may have just sold a pipe for them. I like the sound (in your description) of a strong mid-range with all-out rev capability., though I don't have any desire for a "mellow transition" pipe.

Question: I may have overlooked this, but what pipe you are running on your R when the Mrs.(with an ESR) is staying on you in a drag race?

[Tbcoplin]

I have a Paul turner on my 86. It performs extremely well.

I tested the DG and FMF back to back on my ported MX racer. Keep in mind that I run really tight compression, but have the cylinder raised and ported for good top end, while keeping a strong low and midrange torque.
The DG definately falls short on this engine vs. the Fatty. The fatty felt like it had a little less bottom end when I switched to it from the DG, but it really did not affect the trike.But the Fatty definately pulls harde in the mid and top end on my Ported engine.

When we raced, I raced her both with the DG,and FMF on mine. No matter what the ESR kept up with them. Actually, with the DG I think she was able to run me down and pass me at the end of a 400 foot field run.

If you do get a ESR, just keep in mind that this pipe works good stock, but will perform way better with some mods. Particularly, a CR head gasket and reed cage along with a larger carb, would probably make a huge difference on a stock engine with the ESR.
The guy that ported my engine, runs a similar engine to mine and switched between the PT pipes and ESR pipe.
He said one made it hit almost out of control. I guess I forget which one he was referring too.


I plan on putting her ESR on my trike this spring to see what it does. Then I will probably order a second ESR.

Its simple, if your under 370 cc's and on gas, stay with an inframe, if your going bigger, then dont waste your money on an inframe, spend the money and get a Shear, there is no comparision.

Do your research before doing anything..there is what most think as going "fast", maybe a 330 with a 4 mil and an ATC5 pipe...then there is fast...and ESR/CT dont sell anything "over the counter" that is fast, and those that tell you they do...aint seen fast!

Paul Tuner Hi Rev , Love it ! Rev's to the moon ...

[powerslide250R]

PT all the way.... my 85 is the best 250R i have owner and the PT pipe is music man.... and hang on as well !!!!!

[Jason Hall]

Most of these guy's that are praising the PT Hi Rev have never ran a ESR pipe. The ESR has the smoothest low end pull I have found so far. It lugs good on my ported R, It has very strong mid and top end also. On my engine the ESR pulls top end better than the PT Hi rev. For all around riding you cant beat the ESR. I tried a PT type-6.This Is the pipe Mosh was reffering to, that pipe was CRAZY on my R. It would pull one gear higher In the same turn as the ESR, but pulled so hard (out of control with stock swinger) down low through mid RPM's my boy did not like It. We then stuck with the ESR, smoothest best power IMO. I would like to add that from a FMF to a PT Hi rev the difference Is AWESOME. The PT Is a Great pipe, when I changed from the fmf to the PT hi rev, I was screamin wheelies In 5th Instead of 4th on the road. So both are great pipe's.
