Since some weeks my engine cogs when I am riding in low speed and engine speed is low as well (for example in roundabouts when I am behind slow cars). When I accelerate the engine cogs sometimes and then follows the acceleration very rapidly. Sometimes I an startled and this is no good feeling. I wonder where this problem comes from. The engine runs also irregularly when I am riding slowly through the city for example. When I remember correctly I did not have this problem from the beginning. After 1.000km I have mounted the REMUS Powercone. I did not change more. And after the change to REMUS I did not recognize this problem for a long time. It began about two years later - so I do not tink that it comes from the exhaust change. Does somebody have similar experiences with his XR1200 and how did you fix it? Cheers Günter

Try a set of new spark Plugs, clean the air filter. Crappy Gas. Easy stuff 1st.

Sound like you need a tuner Gunter.

Welkomme Gunter! I assume you are in Germany

.......I agree with Scotty, I think you need Fueller.....but it looks like you have had your XR at least 3 years so a spark plug change is a good suggestion..............

Hey buddy,

These motorcycles come with a Tachometer. What RPM are you talking about? If you are under 2000 RPM, then you are "lugging the engine" - and that is bad for the motor.

I agree with Joe. My XR will start chugging & making noise in the primary as it want's to stall at real low speed, low rpm's. I'm sure it's normal, just need to pick up the rev's a bit. My XR does have a Scotty Mod, so it tends to make it a bit taller down low, not wanting to chug along very bad.

Your engine will be running lean with the pipe Gunther ,so as the above suggests Tuner and letting the engine rev a bit.

Hi Guys, thank you for so many replies in short term. Yes, you are right, I live in South-West Germany (Black Forrest region) close to Switzerland and France. How is it possible to get the Scotty Rev to the engine? Do I need Powercommander or something or is my mechanic able to program it directly?
The Problem appears when I am under 2.000 rounds per minute. Sometimes you can not avoid it when you are in very slow traffic. Then you have this in the first gear and it is not possible to work with the clutch all the time.
I think that the spark plugs could also be a good hint. Gas quality is absolutely no problem here. And I run my XR1200 only with 98 octane so I think it should be fine. Perhaps you have an info to the Rev-question? Here I have been told that it is necessary to mount Powercommander and then you shoud perchase the license for a mapping. All together should cost about 1.000 Euro. I wondered a little because it was a problem that appeared not directly after mounting the REMUS. So there should be a problem that is not related to the exhaust (too less gas because ot too less ram pressure?).
Viele Grüße aus dem Scharzwald! Günter

Hallo Gunter,

Na also:

Den scotty mod ist dafur dass man die motor beim hohe geschwindigheid nicht zoviel touren machen lasst.
Dass hat nichts zu tun mit deinem problem:
Unter die 2000 touren kan den motor schon ein bischen unruhig laufen aber nicht so ubel wie du es darstellst, also ich wurde die folgenden sachen machen

(entschuldigung fur mein mieses deutch ;-))

1st step: please change the plugs and the airfilter
2nd step: use a device like the patriot top fueler (you can buy them from one of the sponsors), to enrich the fuel/air mixture a bit

If you want to go further you can always buy a power commander or TTS tuner or similar and get the bike sorted by a professional tuner

let us know what happens ;-)

Hi Alaskan, danke für Deine Antwort in Deutsch! Ich konnte alles verstehen - Dein Deutsch ist gut ... :clap:

First of all I will change the spark plugs. As I mentioned the problem increased over the months. If it would come only from REMUS it must have been from beginning on - I suppose. So I do the first step and try it. If the problem still exists after the new plugs I will go further steps. Then I hope that my HD-dealer is able to provide the patriot top fueller because I do not want to have more power. For my oppinion it is okay for me. I think that it is also healthy for the engine to enrich the fuel/air mixture a bit because of a better thermic. Let's see what happens after changing the plugs. Thank you all for helping so quick! Cheers Günter

Don't ask your dealer about the Patriot Top Fueler (PTF). He probably does not know what it is.
You will find the PTF banner on this forum. Click on the banner, and you have access to their website. The PTF version you need is the M141200R Top Fueler Sportster Race Only. Don't let the "Race Only" scare you, it IS the version you need. There is a discount for xr1200ownersgroup members. Payment with Visa is easy and safe, and the postman will drop it in your mailbox one or two weeks later. You may have to pay some import taxes and VAT (MwSt), as the PTF will be sent from California. "Streettracker" is a forum member who works for PerTronix Performance Products, the company that sells the PTF.
Installation is easy, really straightforward, and the base settings are spot-on.
Most users are satisfied with this solution, so am I. Check the thread dedicated to the PTF, lots of informations there.
Your bike will run better, cooler and smoother.
Und übrigens, viel Spass im Schwarzwald mit dem XR!

Thanks for the good words about our product E.H-57
The PTF will help with low RPM fueling problems as an inexpensive way to cure those issues. It should help a lot. Your dealer in Germany will not be familiar with this product, you can buy it direct right here with the forum discount http://www.patriotpipes.com/XR1200.html and it is a very easy install, with no computer or Dyno tuning necessary.

Here's the thing though, Cracking the throttle on these bikes at under 2,000 RPM will cause a bit of a lugging situation, It is better in that case to work with the clutch a little bit to help get the RPM's up. I know that can be difficult to master, when i traffic at slow speeds with cars trying to run you over, but it is all part of good motorcycle riding. Do not do the Scotty Mod to the gearing as this raises the gear ratio and will only make this situation worse. It is for lower RPM at higher cruising speeds.

@streettracker

I have been in contact with Patriotpipes and I asked for a detailed assembly instruction for the top fueller. Optimal it would be with pictures. It is an electronic part I would implement into the system and I fear it a little because I am not so skilled. Unfortunately I did not get more than the instructions written in the PDF file to the product. Perhaps somebody has made an assembly instruction for himself or for the forum? Or exists something in youtube? Would be very helpful for me. As long as I am not sure I hesitate to order the top fueller.
By the way - today I will get my new spark plugs. I will mount them this afternoon and then I will be in the Black Forrest to test them. The airfilter can not be the problem because it was changed not too long ago.

Xelsix, here is a link to a thread where a member in Bahrain installed his Top Fueler. It is complete with pictures:

Installing a PTF is much easier than changing the air filter on this bike. It is a simple plug and play as long as you remember red/positive black/negative.

Yesterday after work I rode to my Harley dealer and bought the spark plugs. Then I replaced the old ones on site. On my way back home I recognized that there was no improvement. Today I rode about 100km in the Black Forrest. Now I am very sensitive because I consider very much about this topic - because it is very current to me. So I experienced an engine very similar like I have told you in the beginning. Later the ignition seemed to fail sometimes even in higher revs when I rode without accelerating. All in all the engine was very rough - and I am sure that it changed during the day.
I considdered that the following reasons could be responsible for the changes: During the day the weather changed and also the temperature was different later. Also we were up to 1.000 hight meters. Is it possible that the engine shows differences according to these circumstances? When the engine works too lean I could imagine that these circumstances could have the running even leaner as before. I am curious what you think about my theory ...

Another theory: At the beginning of this thread I told you that the engine worked better after I had mounted my REMUS Powercone recent. The changes came after 2.500 or 3.000km. Is it possible that the REMUS was more "open" after working about 3.000km and so the ram pressure was lower than in the beginning? So it could be explicable why the engine worked more rough after riding the bike 3.000km. What do you think about that? ...

In the meantime I have checked the mounting of the Top Fueller in Bahrain and I think I can cope with it. If you have no other ideas or if you think that the Top Fueller will resolve the problem I will order it soon.

I am looking forward to your answers - thanks!

Xelsix, you have to get a Tuner on that bike soon. There are many different tuners that will work - PowerVision, ThunderMax, Screamin' Eagle - but the perfect tuner in this case is the Top Fueller. It is easiest to install, easiest to program, and gets the highest reviews from its users. You can spend more time and money but I don't think there is a better solution.

We will help you through it . Good Luck!

+1 on the Top Fueler for Xelsix, you and your XR will be happy :nana: you did.

I'm not convinced this is a fuelling problem, could just as easily be electrical, bad contact somewhere or ignition circuit.

He says this started two years after fitting the Remus, if it were a tuner issue it would have shown before now, the more I think about it the more I'm thinking electrical.
