Exhaust Options for a '86 250r... Need help!

[ChopDunkSplit]

Actually Cuztom Racing is correct ESR does make a pipe.. its called the CT5, but it will run you about $320...

[ChopDunkSplit]

Thats a nice bike sir... What kind of silencer do you run Mosh? It looks clean paired up with that ESR

oh! kewl!! how the he** did i miss that on their site?? lol


oh and that IS a beauty Mosh! BTW, at what point would you consider heavy mods and better suited to othe ESR pipe? Big bore and better? I will be getting mine ported soon, already running the ESR Air Stryker, 1nder racing reeds and torque spacer and they seem to work real well with the Fatty....Fatty be good with porting, or would the ESR be better suited? sorry to hijack, just curious while we are on this...

[ChopDunkSplit]

Hijack? Nah, No worries at all, I'm a complete NoOb when it comes to 3 Wheeled contraptions... That's what I'm here for, to soak in all this "Trike Knowledge" the more posts... the more I'm seeing the big picture..

I wish I wish I knew what kind of pipe I had on my flat track 250R I bought it years ago off ebay no name no nothing its a sectional and makes perfect power throughout the rpm range. Alot of times you can snag you an older sectional pipe from a member here and most likelly then not they will make the best power over any pipe you can buy new.

[Mosh]

I will try to answer your guys questions here as best as possible.Bare with me as it has been a GOOD Monday night..LOL

That pic is my Wifes ride.
At the onset she had a stock engine with a PJ 36 mil carb from a CR 250R.

My trike had a PWK38 mil carb with Port work,(Which the guy that did the portwork knows his stuff!) and a CR 250 head gasket and V force3 reeds.
When her machine was Stock with the ESR pipe, I beat her out of the hole, but she would run me down..
Keep in mind she has about a 80 pound wieght advantage on me.
We both run plus 3 swingarms.
Her engine got weak and I put a .020 piston in it with That ESR Pipe and a 89 CR 250 head gasket..
Mind you, My machine is heavily modded..Port Polish, PWK 38 Mil carb, V force reeds, .050 bore...FMF Fatty And straight 110 gas...
She can damn near eat my trike alive with That ESR pipe,Boyeson reeds and CR head gasket on a stock .020 over jug..I can get her everytime, but if I fall asleep, she gets me..She can get me if she is on her toes.(My machine is getting hindered bigtime with that FMF pipe) She can even run me down if I get a jump on her..That is attributed to that ESR pipe she runs.
Now keep in mind the weight advantage...I almost give her 100 lbs. Cuz I am a fat azz.

If it was me,and I can buy that ESR pipe and a 35$ CR head gasket...I would run that steup.
But DG pipes are CHEAP and get great bottom end on a stock motor...So if I had 200 bucks to blow and didnt want to open up my motor..I would slap a DG or FMF fatty pipe and 86 (34 mil) ATC 250 R carb on it..The stock 85 Carb was good for throwing at stray cats,and that is about it if you ask me. lol
If I planned on spending 800$..Definately portwork, a PWK 38 mil carb, CR headgasket and the ESR pipe..Hands down a good setup for the average or above average rider.

If you put that ESR pipe on a stock motor for trails and midrange power....You may get disappointed...
At very minimum, you need some good compression and a 36 mil carb to get useable gains from the ESR pipe.Dont get me wrong, the ESR will work on a stock motor, but it is like throwing a Edelbrock intake and carb, on a 77 Chevy station wagon. It will work, but not at it's premium level.
Porting will make that ESR wake up like crack addict.

That is a question we have never answered. We have no idea.
We have been told it is either possibly a Bill's or Motofast silencer.

[ChopDunkSplit]

Thank you Mosh as well as everyone else who has posted in this thread... very informative, something to chew on especially if I get deeper into modding.

Nevertheless, your saying I didn't do quite so bad with the FMF Fatty and DG Oval Silencer... Nice to know.. My R is an '86 model so it came stock with the 36m Carb.

Although, I haven't even laid eyes on it in person yet, they guy I bought it from obviously didn't know too much detail about it himself.. except that it runs like champ he claims, and never gives him any problems... He did mention it has a Kerker Silencer and Maier Rear Fenders but other then that its pretty much stock, and the engine has never been opened to the best of his knowledge. I havent seen a single person on this forum that mentions Kerkers... so I went ahead and ordered an entire new exhaust system, cool though I wanted a Chrome/Polished Finish.

[Mosh]

No worrys..Chrome and polish requires more cleaning...So dont be sad..
And FYI the 86 R carb has a 34 mil rating.

[88 Turbo Coupe]

So you might want a pipe with low to mid hit when you goose it.

so Mosh: one other thing i forgot to mention about my ride is that along with the things listed, i do believe it has a thinner than stock head gasket in it as the compression is too high for pump gas. I bought the trike from my brother who did the build, he got 230psi before the rings seated. He couldnt figure out for the life of him why the comp was soooo high. Then he remembered noticing how incredibly much thinner the gasket he got was than the one that came out of it, so we inferred the higher compression was due to the head gasket. Its bored .060 over now, other than that, no internal mods. Just the 38mm ESR Air Stryker carb, 1nder Racing reeds, cage, and torque spacer. So, if im reading you right, it sounds like i may be ready for the ESR pipe now, let alone once i get my porting done. Sound about right? Just to give an idea what the current goodies have given me including the FMF Fatty, it settled on a 195 main jet at about 50 degrees farenheit (i dont ride it in cold weather, and dont mind being a tad rich when its hotter out)..thats quite a jump up from the stock 142. And she hits REAL hard up through the gears. I cant wait to see what its like with a port job and head shave, should be fun....

these are the reeds im running... http://1dirracing.com/catalogs/produ...34&cat=0&page=

HEY Red Ride.

Your buddy at 1dir racing ripped me off a while back. He's a real POS. Do yourself a favor and buy some REAL reeds..........V-Force. And leave that scum bag 1dir behind.

I dont really have any feedback on your reed set-up. I have ridden ESR pipe on Rad valves, Boyesons and V force cages, and honestly, I think that any aftermarket reed valve is about the same in performance.
I know they all have different flow rates on a bench, but many times that does not always translate to real world seat of the pants losses or gains. It is all in preference if you ask me, unless you have a full out drag engine that needs maximum breathing..Then Flow rates could be considered..That is just my opinion though.

It sounds to me like you have a CR head gasket on the trike now.
The ESR is a great pipe...On a modded engine that has some bottom and mid to it, but is looking for a lot of over rev it is a good add on.
The powerband is smooth with the ESR and really pulls hard in the mid, and the top end seems to go on forever.
So if you have a hard hitting bottom engine, with those compression readings, it sounds it should be a low end torquer, then the ESR pipe should give you noticeable gains across the board with your current set-up.
Like I said earlier, the ESR works on a stock set-up too, but you will find that the stock engine can't pull the pipe to it's full potentential, and it will leave you looking for bottom end on a stock engine.
It is hands down the strongest constructed pipe I have ever seen.

I know it seems as I am pushing the ESR heavy..And for all out gains I feel it may be the best pipe on the market for a hopped up R engine.I know their quad pipes rock out too.
But I still like the DG and FMF.
I like that HARD hit into the midrange most of the time, and the FMF fatty gives that, but signs off up top compared to a ESR.
Stock motor on a budget that needs low end for trails, DG is good.
A little more ummph on that same Stock engine the FMF fatty is better, and leaves some room for moderate engine mods, and still works well also with the hop ups.
A pipe that almost has infinite power to work with and strength, the ESR is the way to go.

I would mod out an FMF Gnarly off either a KTM 300 or 250. you would get some torque and it is close fitting, you just need to adjust the outlet location and inlet mounting style. My next project....
