Just replaced my manifold and rebuilt my carburetor and yes the new manifold had rough edges. I ground them to a smooth rounded curve and the back of the T smooth. Runs great ! FYI , keep on hand a fuel valve o-ring, after 83,000 miles it split and leaked. Glad to be riding after two years of it sitting. When your 69 you have to stay in shape for this heavy steed. Live to Ride and Ride to Live !

Very simple actually to me it seemed easier in real time vs following this live feed good job thanks

Great videos thanks for taking the time to help the roadster owners out there

I used a dremel tool with an attachment that was round with little flaps of sandpaper it was just the right size. I like how you cleaned up the ends also

well explained I'm about to do some work on my '07, and your video help a lot thanks again

So this is actually de burring your intake manifold . Nice video

Nice video walkthrough. Just remember, any gain in horsepower by porting the manifold, is a trade-off with getting less miles per gallon on your fuel consumption. There is always a trade-off, between more horsepower and more frequent stops to fuel up, especially when cruising long distances. Just saying. I have a stage 1 mod, with a K&N filter and Cobra Speedster Longs, exhaust, but, and that was all the trade-off for me, decided against porting the manifold, and weakening the rubber manifold, walls, too. Too each his own, as I say, though. Happy trails to you.

this is great video! I need to clean the carb of my 06 road* and I have never done b4, I feel kind of intimidated by this but after watching this video I think I can do it. My bike problem is that need the choke for about 2 min to idle fine, she runs fine after but the starting part is what is hard for her, hopefully a good cleaning will fix the problem. Thanks again.

You did the best Video. Verry nice job. I did it the same way. Please do more Videos. Best Regards from Germany .

Хороший мотоцикл , слежу за твоими видео , у самого такой же только 1.7 ) продолжай !) удачи тебе )

Good video. I've done 3 of my Road Stars the same exact way James did on this video. Take your time and there's nothing to it. You will experience a noticeable horsepower increase. Good job on the video James. Ride Safe..

I have both. The PR version and the stock one. The biggest difference in the PR version is that when you look through the manifold from the carb side you can see into both of the motor ports about 3/4 on an inch. Not on the stock one. The biggest gain is 1/2 throttle and above. The flat spot when it pulls with the stock manifold is gone, now it continues to pull all the way to rev limiter.

im guessing its the same for the roadstar warrior 1700?

Can you tell me what all you need to do to bypass and remove the fuel pump

Great videos you've been showing. I really appreciate it. Question, where could I get a nice passenger cushioned backrest like yours. My wife would greatly appreciate it.

Noticed the intake manifold nipple has a cap on it. Is the AIS removed on this bike? Or should the nipple should always be pluggled?

James how are you. Need your help with my 2002 yamaha 1600. My bike idle to high . It's free spinning.when I try to idle it down. Rear foot brakes not working

Great video brother I was going to do it myself but I'm just going to order a barons ported intake brand new but all your info is greatly appreciated

I just bought a 2002 Roadstar 2 days ago. This is my 1st v twin. I love your videos. Using them to go over and learn about my bike. Do I need to get an oil cooler? My buddy says its a mandatory item. Thank you.

So did it make a noticeable difference? I've got an 02 with high compression pistons, bigger carb, ecu, Vance and Hines pipe. It was my dads bike he had all the work done but I don't know if they replaced or ported the intake manifold, so im like 🤔.. I have a shadow 1100 also that I did a similar thing on the the intake Y pipe and it did help it quite a bit..

And what is the purpose of porting and what is gained ?

Nice video, good information. But missing port matching. The mismatc between the manifold and the port opening probably is the most congestion you may have at your manifold. If you don't do port matching, all this work is - well, not pointless, but also not finished.

Hay there I have a 2000 Silverado has around 64,000 miles on it. Daily rider. Was wondering if that’s a steel manifold? The one on mine seems like it’s plastic and I’m sure I need to replace it has cracks all over it 😅 Just noticed that one looked different.

so just to be clear, every stock oem manifold should be done like this because factory manifolds are molded in a way that restricts the airflow a bit? and also how much should you take off? it seems pretty thick where it makes the turns

Wow, really well done video. I wish you did a follow up with results. Was it worth all the work?

Is it illegal, or is a warrantee VOID IF you remove the AIM system from those bikes in question (Yamaha Roadstars)?

Will a Dremel be able to reach inside where I would sand the manifold

So I'm basically rounding out the sharp edges inside the T correct also wanted to know where u got the lil plastic cap for the piece on the manifold I don't have on on my current or new one

hey bud seems like you know the bike pretty well I need some help my bike won't start it just clicks I was wondering if you knew where the starter relay was ?

So what does porting do for your bike then?

James, did you notice any significant improvement when you ported? Did it make a big difference?

May I point out that it is a carburetor, not a corburetor.

Great video thx! Noticed your fuel pump is either bypassed or hid somewhere else. How'd you do it?

Very nice detailed video.I traded a Klr 650 for a 05 roadstar midnight Silverado .I love my new bike,but after it warms up it makes a lot of noise from the engine.Sounds like the valves need to be adjusted or something.I started running synthetic 20w50 mobile 1 and that made it better,but it does seem a bit out of the norm.I got the bike with 5000 miles on it ,and have since put another 5000 on it.Do you have a Email address I could Email you easier.Thanks and keep the awsome videos coming.

So, with ALL that work, what did you gain? (Was it worth the effort?)

Hi realy like your roadstar posts its strange cous in sweden same bikes name are wildstar. My question is why do you porting the manifold ?

It makes little difference you can hardly notice it.

I’m surprised these big bikes only have one carb.

You didn't show me what gas lines to disconnect at 3:14 :(

Those allens are 5mm...

Belt sander

Man, thanks for video, but it's not a VTX! IThis bike like a tractor: slow ride :)))) Ceep calm and do not any things while it works! (I have same bike, '99 RoadStar 1600, same problems with fast gas masturbating on the road- THIS BIKE DON'T LIKE IT !!!!! Just let them work long time and happy).

Informative but I cringe at your lack of care protecting the chrome bits while you work.

It should be illegal. It's a waste of your fucking time. Might as well instead count your pubic hairs while wearing boxing gloves and you'll achieve the same result. Just get irritated. What results are you thinking you're gonna get? Be serious guys!!! Polishing rubber. That's rubbish!

I would think porting a manifold would also include matching the part where it connects to the head.
