baker 6OD

[SuperJoe]

first post here after hours of reading. i was referred here by a guy at a food stand at phx bike week 2013 that had a blue buell parked outside his food shack. i noticed his pipe had dual exits and thats what started the convo about exhaust and this place. i have a stock 04 xb12r. i like riding the bike just fine as it is, but i was wondering if anyone has done a 6 speed conversion. i looked through the lit i could find on the baker site and it seems that i dont know enough about HD models to keep up with the options. there must be a case change after 03 as what i read states that the gears will fit through an 03 sportster. reason i ask is because i was walking through the bike junk yard in town and think i found a sporty with a baker plate on the side of it. im not a 100% though as i didnt know what it was till i got home and looked it up. ive had my bike since day one with one mile and never thought to add to it or change anything. any thoughts on this subject? ive been through all thread titles in the stickies and the search seems to elude me slightly. thanks for all i have learned on exhaust options and opinions so far. this will be quite the resource

Cant do it on the xb bikes. But it should work on the older tuber models, which I happen to have now. Feel free to pull the transmission and send it my way. They got rid of the trap door inside the primary so you have to split the case to change the trans. This also means you cant fit a different trap door to allow for the 6th gear. Maybe it could be done with custom machining to the case but I dont think its worth all of that.

I completely agree it could use a 6th gear. I think everyone here feels that way.

I think you can only do this on the 03 xb9s because they still have the trap door, right?

 

[konarider94]

None of the xb have the trap door (except the xb rr) even though I think the 2003 sportster still did have one.

 

[greasyxb9s]

So why can't it be done? A door could be made easily....

 

[konarider94]

Oh yea i could hammer this out in an afternoon in the garage. Im not sure what trap door you are thinking of but I think you should search a little more. The 6spd kit comes with a different trap door but the case is not machine to accept it. Which is why i said you would have to machine the case in my earlier post and why you have to split the case to do any transmission work.

Ah I see now.... it could still be done..... with the right equipment

 

[snrusnak]

Can you use a case off an older bike? Or does that cause other issues? I'd LOVE to have a 6 speed. If there's any possibility of having it then during a rebuild would be a good time.

 

[konarider94]

yea sure it will bolt right in, go for it.

Are you being a smart ass? Or will it really work? I don't see why someone would go through the trouble of machining a trap door in a newer case when you could just swap it for an older case.

Picked up on that I see, I guess Im in an easily annoyed mood today dont take it too seriously. You wouldn't machine a new trap door into the old style case. No one will ever do that...ever, prove me wrong.

Have you even looked at the older cases before asking that though? There are quite a few differences. The main one being how the swingarm attaches to the back of the engine. And i dont even want to hear well it could be done.

 

[snrusnak]

Obviously I haven't, that's why I asked. If I knew the info then I wouldn't ask...

The Factory XB cases never had a trap door. The Sportster cases with a trap door can not swap with XB cases. All the motor mounts and engine tie bar mounts are very different.

The XBRR engine cases ($$$$$$$ and can't build a standard XB motor with them) and the Buell Race 3.6 cases (Very rare but I just bought a set) are the only XB style cases that had a trap door. Those trap doors are different than the Sportster trap doors so special parts would have to be made to fit a Baker 6 speed trans, if it would even fit. I'll take some pics of the 3.6 cases I bought when they show up tomorrow. They have been on eBay for a long time and I decided to buy them. They still need lots of machining to finish them but they are really neat. I'm thinking I might build a special motor out of them!

Anything could be done you just have to have the right stuff the set of mind and $$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$

 

[greasyxb9s]

For the $2000 or $3000 bucks for the baker kit I don't even think its worth it. Keep a happy medium for low end and change over to a chain drive and adjust for top end there.To be honest would we even benefit from a extra gear and gain more speed anyway?

 

[konarider94]

its not for extra speed its to drop the rpm in the highway cruising speeds without losing any of your bottom end like a gear change would

 

[greasyxb9s]

Yeah I understand that 70mph on the highway I'm around 4000rpm it gets annoying

 

[SuperJoe]

that pretty much settles it in my mind. thanks for the replies, especially the ones with pics. i didnt know what they meant by trap door. its very obvious now.

 

[user_deleted]

Very rare but I just bought a set

of course.

Coming from you, it`s a bit scaring .... You`ve got my attention
