need a quick answer please can the XB 12 rotor and sprocket assembly be used in place of the origina l parts with the longer XB primary chain this is a 99 x1 edit need to ADD I did this allready and I am noticing a slight rubbing noise from the primary area at idle. I am thinking it could be the rotor bell making contact with the case but it's so slight I don't remeber if it's normal or not. (Message edited by 12mpghwy on March 02, 2010) | ||

The parts I used are 32494-04 sprocket With rotor and 40147-04 chain | ||

Loren's thread detailed the install. Will search for it when I get home, I have a link saved somewhere. | ||

"i" plan to put the XB12 motor sprocket and chain on my S3T which would be a RETRO FIT ... Have already done this on my 2000 BLAST P3 which was a RETRO FIT with no problems ... Want my ADJUSTING PRIMARY CHAIN Class 101, e-mail me(Ljenne73c@verizon.net) and it is yours ... | ||

http://www.badweatherbikers.com/buell/messages/476 23/433236.html?1233572275 I found the rotors to be the same, but the inner hub depth on the XB sprocket was shorter than the one off my '02 S3T. I'm betting the rubbing you are hearing is the rotor rubbing on the stator coils. | ||

Rotor to case/stator clearance is set by the sprockets hub I have seen numerous posts refering to the xb 38t sprocket as being interchangeable with the tuber 35 tooth. Can anyone confirm this? Does it require a different crank spacer, that is the one that the seal rides on can someone with a parts book help me out | ||

can i put a 34 tooth sprocket in my 99 m2 and if yes what year xb and what chain would be the best fit ??? i have uk final drive gearing and want to lower the gearing a bit doing it this way i dont have to alter the speedo sensor, | ||

All you change is motor sprocket, not the motor sprocket and rotor ... | ||
| Brinnutz |
But, if wanting to up the charging system and adding the XB12 sprocket, you could just switch out the stator, rotor, and sprocket and be good to go right (with changing the VR also)? | ||

Buellistic the problem is if the rotors Are the same the rotor to case clearnance is set by the sprocket. Do you know of anyone who has actually done this with a tuber and not a blast (Message edited by 12mpghwy on March 03, 2010) | ||

Ok took it apart this morning... Rotor was indeed rubbing on the case only in one high spot, which is the steel plate that retains the stator wires. The back of the sprocket hub is 2mm shorter, but the rotors are identical otherwise. So indeed you cannot use an XB sprocket on a tuber without other changes. fix would probably be a different sprocket spacer that being the one that the seal rides on. | ||

A good MACHINIST can make you a spacer ... | ||
| 12mpghwy |
a newly machined spacer would be the right way to do it. for ref it needs to be 2.45mm thicker than stock. The spacer also sets the chain wheel alignment. I am impatient,so I found a washer that is within .2mm thinner than 2.45mm and I am using that as a shim. The spacer does nothing else but set the chain wheel alignment and that's not .2mm critical. Its a steel cut washer from a zx7 axle. that mikes out at 2.25mm thick all the way around, so while using a mild steel washer as a shim can't be good it shouldn't be terrible either. Its back together now, and while there is some noise from the primary its def not rubbing the case. Ironically enough I think the amount of noise coming from the primary is about normal, I was just being over sensitive yesterday. | ||

OK so far ridden 160 miles with the new gearing. I would highly recommend that no one do this. this gearing sucks, I just did this because I needed a new rotor and none of the local dealers had the OEM one so what I will do is take of the rotor, and put it on my stock chain wheel. 3K RPM at 80+ is too high numerical gearing If anyone (Buellistic) wants to buy the chain wheel and chain cheap (and they have only 160 miles as I have said let me know.

12mpghwy: Of course "i" or someone should have told you that you might need more HORSE POWER to pull the taller gearing ... You can correct this if you are running a 29 tooth counter shaft by going to a 27 tooth counter shaft sprocket ... 3K a is not too high to cruise at,you just got to be at 2500 RPM or more ... | ||

I'll take those parts off your hands!  | ||
| Brinnutz |
Aren't you at like 3700-4000RPM at 80mph with stock gearing?? Wilson | ||

I have a 99 X1. It cruises @3800 RPM @ 80 MPH. In my (limited, I only been able to ride the bike for the last five weeks)experience, cruising at this RPM is good for the engine and good for 40-45 MPG on highways. Ride safe, Chris C |
