430 air cooled expansion chambers

what are you running?

How did it help in power delivery?

Was it worth the cost?

How much lighter is it from stock?

Dont ask Schimm! The one he got didn't fit very good and was (is) a sore subject. It would be good to have a reminder of the brand though.

Just a "fit" report

Your thread got me motivated to put my new Vintage Iron Retro Rocket pipe on my 82 430XC. Its only been hanging on the wall looking cool since the June. Most of the fit is good. The bad, had to remove exhaust spigot from barrel and "massage" pipe to fit. Next bad, upper pipe mount rubs head, placement sucks and will be redoing that. My Ashe pipes have alot better upper mount. Next bad, pipe hits frame down tube. The good, rear section fits great, mount actually lined up which suprised me and silencer fit back on right and is straight. The "fixes", going to cut a 1/4" off of the pipe at the exhaust spigot, should fix the down tube interference. Going to remove the upper pipe support and fab my own. I could not get the pipe "wiggled" enough to have a straight start onto the exhaust spigot because of the upper mount hitting the head. Hopefully removing it will allow th epipe to go on without removing the spigot and the trying to bolt it back onto the barrel with the pipe attached. No ride report as its winter here.

My opinion of pipe: I have a Ashe pipes on my 82 CR250, 82 XC250, other 82 430XC and my previous 83 500XC They fit perfect. Maybe I was spoiled with them. As in most aftermarket parts this pipe needs a little work to work but I'm kinda picky.

I think that is why if i ever go with another pipe i will take my bike to Maico`s only in Ontario,Ca. and have them make one that way there will be no fitment problems.

I was just wondering if the performance gain is worth the $250 and also how much weight it will save.

Just doing the pipe in each hand thing I didn't see much weight difference. I think it would be a good idea to have the bike there when the pipe was made-no excuses. I modified a 83 500XC pipe to fit in a 82 chassis. Mocked up a chassis, engine, tank, airbox, side panels etc. to make sure it fit. Last thing I wanted was the guy to be mad at me. Never heard a word bad so it was all good.

A good friend who has raced bikes since 52 told me the greatest weight savings is the rider! He's was always 130lbs though and me being 265lbs I think he may have been picking on me. He said the best weight saving on the bike was the tires. Each brand has a different carcass weight to taken in consideration.

Amazing how we will all compare wieghts of parts but two weeks of a low carb diet would put us all ahead on the weight or rider to weight of bike curve!

LOL!

Back to the subject at hand... wha about Circle F.. do they make one for the 430's?

[oldhuskychuck]

ok, i gotta toss this in,,,
like me, most of us are older, fatter, and slower then we were many years ago,
do you really think a 300.00 pipe will make you any faster, younger or lighter then you are??lol..
however....they do look cool as hell..and might make someone stop and check out your old iron at the track...
i doubt any of us, would feel the differance in 5 to 10 pounds on a motorcycle...
hell, i doubt that we could tell 30 pounds spread over a motorycle...
admited, id spend 300.00 on a bad ass looking pipe, swingarm, ect...will it make me faster?? not likely....but in my mind....im smokin fast lol..
i tried a Bike with a Circle F pipe, a 74 400CR compared it to my stock piped works bike 400 CR....it sounds real cool...but actually seemed slower, maybe a little more top end,
but in a flat out drag race, my stock piped tuned, Bing carbed, moto plated, CR smoked his Circle F piped, Mikuni carbed, Penton statored CR...and not by just a little...
smoked it...
if it aint broke...dont fix it...
his bike does look sweet though...and that in itself is one reason i would buy a after market pipe.

Thanks for slapping me back to reality.

But you are right, they are really cool looking.

Heh dez, I'm having hats and t-shirts made, welcome,

This is me: Nothing is ever "practical". My daily driver back and forth to school, I teach mechanical tech. at the local college, is a 39 Chevy 5 window coupe. It was a real "gasser" out of Sacramento in the early sixties. BB Chevy with a tunnel ram 2X4's, ridiculous cam and 4 speed with 4.88's. A Yugo or Festiva would do the job perfect right? My last service truck I had for my diesel repair business before I started teaching was a 62 KW conventional 2 axle. I built a twin turbo'd 700hp engine for it. 200hp would of worked fine but thats boring...... The list goes on and my wife finally after twenty years quit shaking her head. Now for motorcycles! Lets see, I'm 44, 265lbs on a light day, really bad back-reason for teaching job and two shot knees. Practical bike would be a CRF150 Honda with max speed of 35, governer controlled remote by my wife. Which is actually my level of riding anymore! So, how many of you guys fit the above description? Need to know for the hat and t-shirt order.
Any suggestions for the name? Has to include some of the following, old, crippled, fat, bald, still think were 16, good God I hope I never grow out of that one, Once was faster than the the really slow guy and the most important one- "man doesn't that (me) look cool"

I know it is changing the subject and maybe you have talked about it elsewhere. Have you carved on your reed block parts? I have some 360 ones a guy modified quite a bit. They seem to be the same as the 430 stuff I have, well the air cooled ones. As for the pipe itself, For riding in rocks the way it goes down then makes a tight turn and goes back up is great for not getting smashed. I would expect a less tight turn there would help. I am assuming the cr pipe is similar to the wr. To get lighter you basically have to go thinner or shorter right?

Hey!
I thought I was getting shorter... but it was an optical illusion.

Nice daily driver,your students must think that you are the man!

I have a 69 El Camino with a 4speed and posi that i want to set up like a gasser for street/strip

The shirt should say "go big or go bigger,tell practicallity to take a hike!"

"The older I get, The faster I was."

I haven't messed with any aftermarket pipes for the 430. I just love the way they run with good jetting and a good squish distance.

Thanks Pick,

i will put my money into a personal trainer instead
