hi all, i have searched and searched the forums for an answer to this question, so follow me here: my question is, if all the rigid frame kits i see for sportsters and buells are made to fit '86-'03, then, if i have a wrecked '03 XB9, isn't it likely that i could put it's motor into say an M2 or X1 or even S1, frame & swingarm?

I was curious about the same thing since my S3 is getting up there in miles (and not running well right now either). The down draft intake would have to be changed but I don't know what else. I am worried because I ran across a brand new '06 VFR for $3,000 under list that is really tempting. | ||

'03 The 03 part applies to Sportys... as they didnt change until 04... BUT... I am pretty sure it could be done... Chase} | ||

yeah, i need to know if the '03 buell XB's engine mount points are that different from a tuber. obviously an older intake would have to be used to enter from the side instead of the top to accommodate a fuel tank. i am really surprised no-one has tried this. | ||

plus, as i understand it the '03 XB's are a good bit different than the '04's which leads me to believe they aren't that far off. | ||

It won't work without some type of adapter to attach the front tie-bar to the XB cases. It's a totally different arrangement than a tubers. It's not a good idea anyway just for this reason alone - you'd be losing the trapdoor for the transmission. You could use the XB top end on your tuber bottom end and you'd be getting the best of both worlds. Believe me... the trapdoor for the transmission is a major advantage. Even the XBRR cases incorporate a trapdoor, unlike the production XB. | ||

Rear motor mounts are completely different. tubers-swingarm pivot and motor to frame mount=same spot, XB series, motor to frame mount, completely different spot from the swingarm pivot. Can it be done certainly, but that is probably the highest hurdle, as the front mounts are pretty much the same. | ||

right on, i'll just part it then and keep on keeping my eyes peeled for that sweet S1 i can't stop daydreaming about.... | ||

OK, what a dilemma....what i'm looking at here, is that the swingarms are likey swappable, but i have no idea if the rear motor mounts are even doable. they look different, as in the tubers use a bolt-on plate for the rear mount and swingarm mount all-in-one, but that dosen't mean the XB integrated rear mounts aren't in the same positions...what are the odds of this?? i'd really hate to just buy a tube frame to try and mount it up and the rear motor mounts aren't do-able, and then there's the front shock mount as well. the thing is, i'm no stranger to making a franken-bike, i've got a pretty sweet ducati, that used to be a '97 916 superbike, that i stuffed an '02 900ss (air-cooled 2-valve) motor into. so yeah, anybody else out there with input or info? i realize the easy choice would be to just source a frontend off ebay or the classifieds and get the XB back on the road, but where would be the fun in that??? | ||

The reason buell got away from the trap door transmission was for strength the only reason the rr has a trap door is so racers can do quick transmission gear swaps without splitting the cases , how do i know this , i asked erik buell about it at homecoming.... | ||
| Edv |
The eliminated the trap door because it is less expensive to produce not because it is any stronger. Ed | ||

Seems odd that Buell would go to a captured transmission on the production bikes when there wasn't a problem with the old trapdoor (the same basic arrangement has been used since the pre-Sportster 1955 KH model). The trapdoor transmission is more than capable of handling the power of a stock Buell and can be removed easily in half an hour (or less). Typically, only GP race inspired sportbikes have transmissions that are so easily removed. Going away from the trapdoor was a mistake. It may save a few dollars and probably is stronger, but it creates a major hassle if you need to do anything to the transmission. It also takes away one of the few real advantages the old XL mill had on its air-cooled competition in terms of serviceability. | ||

Iamike says: I am worried because I ran across a brand new '06 VFR for $3,000 under list that is really tempting. Mike, If I were you I'd be looking at that VFR pretty hard too... You could always buy the vfr and ride it for a couple seaons until Buell comes out with the 1125GT...} | ||
| Iamike |
Nick, Yeah, I really like the possibility of the 1125r but realistically I don't see it happening for a few years for me. When my S3 started acting up last month I was already thinking that I'd need to sell it to buy an 1125r anyway. Then I ran across the VFR. As soon as I get the new injectors in mine I think I'll post it for sale and see what happens. I'm getting pretty good at troubleshooting mine so if yours acts up, give me a call. I'd gotten a little rusty since I haven't had bike ignition problems for at least 20 years. |
