I am thinking of buying the sportgear and wounder if any one else has tried it and have some feedback to give before i put it in the bike.I have a XB9R -03 and it should fit pre -06 XB.
It lower the 1-4 gear and leave the 5th original so i was thinking to change the primal gear ratio so 1-4th would be original and 5th would be like an overdrive lowering the rpm by 1000 when cruising on the highway and get the top speed up about 30mph.:tour

I have the sportgear in my 2002 Sportster and like it.
Does your Buell have a trap door in the transmision.

No it doesn't have any trapdoor,but should fit any way just take a little more time to install.Have you done anything to the final ratio or are you driving it as it is?
Don't now how i calculate the right ratio on the primal to obtain original ratio on 1-4th.The final sprockets are to expencive and cant find a belt that would fit.

I changed my front belt pulley to a 30 tooth, but I did have to do some minor alterations to the swingarm. The belt was a little to tight in stock form.
I have a calculator to determine gear ratio changes. Let me know what changes your considering.

Well on the sportgears websight it says 13% reduction in 1-4th so i would like 13% less rpm at the lower gears to obtain 1-4th original and have 13% rpm reduction in e5th.
Just browsed the web and find out that the original ratio and sprocket size are 34/57 1.676:1 ,think it is for all XB9.

Don't know if you've seen this table, it may help.

If it doesn't I can run some numbers for you but I'll need the following info:
Tire size and stock overall ratio's in each gear.
Or tire size and engine and trans. sprocket sizes, each gear ratio, and front and rear pulley sizes for the belt drive.

Come to think of it tire size is not relevant unless you want to know engine rpms at mph.

Thanks, haven't seen that one.See if i can figure something out of it.
Otherwise is it hard to install except the benefit of an trapdoor.

You have to completely disassemble the transmission, but it's not nearly as hard as it sounds. You definitely want to have a service manual on hand and it's a bit time consuming if you haven't done it before.
My transmission was in very good condition, so I didn't have to change gears or roller bearings, etc.. Although replacing anything like that would be easy when putting in the sportgears.
I did replace the recommended things like the main seal, c-clips, gasket, fluid, and whatnot. Your suppose to use the recommended tools for the job, but a little ingenuity goes a long way.
The sportgear with seal tool, shipping, misc. parts, misc. tool (large socket), tax, and whatever else I might of forgot came to around $860 USD.

OK, Thanks allot.
Sounds expensive and tricky but what can you do when theres no six speed available,would cost allot more by the way.
Now i have some thing to do in the winter,thats a good thing.

Glad to help.
Johnson Engineerings tech support is very good, but they probably won't answer any questions that aren't directly related to their product.
Give me a shout if you have any problems or questions.

Sorry, but you can not have it that way. First the sportgear changes your transmission to a close ratio gear box meaning less rpm drop between shifts so less power lag and this equates to harder aceleration. When you drop into fifth, you still will have a gear reduction but a wider ratio so you will have a slight power lag and a tad bit less pull. If you do what you are saying, you have accomplished nothing because gearing and rpm will be stock. If you want the over drive effect and stock gearing, do as they say. If you install the sportgear and run a 55 tooth rear pulley you will have the best of both worlds other than a six speed $$$$$$. Is it worth the 500 bucks??? Depends on what you want. My xl at 7500 rpm will run about 163 mph in stock gearing, with sportgear addition only my top end will decay to around 140 but it will accelerate like a scalded dog, but the pulley change with it will leave acceleration near stock but push my top speed to 180 mph. Another added bonus is with pulley change my rpm will be about 500 less in fifth gear just cruising along (sorta over drive like). So do you want to open their eyes on a short run or look at them disapear in the mirror on top end, your choice.
