Howdy! My twin brother is the original owner of a 2001 X1, 13K miles and fitted with slip-on muffler and race ECM since new. I have a 2003 Ducati Monster 620 and we took an overnight trip into the Texas hill country. It has been a while since he ran the bike at high speeds and he was shocked when the X1 could not keep up with the Monster at speeds past 90 mph. He asked me to ride it, and sure enough the X1 runs out of steam. You can hit the rev-limiter in each gear, but when you try to go past 90 in top gear, it will not continue to rev. It just stays at a constant rpm. Bump it down a gear, and you can coax it to higher rpms, but no extra power. The clutch does not seem to be slipping, and there are no strange engine noises, no pinging or overheating. Could it be running too rich? Does the ECM have to be reset? Any suggestions would be greatly appreciated!  | ||

Wow that's odd. How does the air filter look? | ||

I agree, that is a bit odd. Mine has always pulled well to at least 110. I'm interested in hearing what the problem is. | ||

Same here for me. muffler condition air filter condition plugs Fuel filter condition. assuming that the engine is in good condition fuel starvation might also explain your problem. consider a fuel pressure check.

My X1 pulls hard all the way to the rev limiter in 5th gear at over 125. I agree, go through the basics, also look at plugs they tell the tale, black or gray? Fuel filter, air filter, broken butterfly maybe? Still got a snorkel? My brother that looks like my twin has an X1 too.... | ||

Nothing like that with my X1, but I had another bike that pooped out about 3/4ths up the rev range. After a number of tests and opinions, it was determined I toasted it and I had the engine fully rebuilt. You should have seen the service manager's face when after a $2500 rebuild it did the same thing. Turned out it was a collapsed baffle in the silencer. Moral of the story: Take your time and diagnose everything before jumping to conclusions. PS: They gave me a significant discount on the rebuild and virtually free parts and labor on everything but normal service during the following two years I owned the bike. Now, that's a Dealer, eh? | ||

Howdy! Thanks for all your responses! Turns out to have been the set screw in the muffler that secures the baffle came out. The baffle was skewed, and was blocking the pipe! Cheers | ||

Sweet! I love it when a plan comes together. | ||

I am absolutely astonished that someone else experienced the Baffling Silencer Syndrome.  Glad to hear it wasn't anything more serious. | ||

WoW! Good call, Outrider... | ||
| Outrider |
Thanks...But not a good call. Just bad luck with a different bike/brand.  | ||

Thanks Dudes! My brother was very happy to discover the loose baffle in the muffler. He stripped off the remains of the glass packing material and set it right. He will probably pack it with new material, since its a bit loud now. As for me, I am still torn between getting an X1 like his, or a XB9R or XB12R. I really like the "hand built hot rod" look of the tubers, and they seen more versatile and spacious. On the other hand, I like the smaller GP chassis and improvements of the XBR. I guess they are like comparing apples and oranges. Both are very appealing and fruity too!  | ||

You need both. I have the X1 and think I need a XB12Ss. The XBs are a good bit stiffer chassis wise I think over the tubers so if corner carving is high on your list buy an XB first then get an X1. | ||

The XB series rides like a "bike suit" It's like the bike is transparent. I took an XB9s for a test drive and it's spooky. You look down and you don't even see any bike there! Just the street. It's like you're flying. I think I will get a Ulysses next year. (budget permitting) |
