I think Tom is giving you some great guidance on this- I'd try the 2.08 and like Tom said it's easy enough to swap up the rear sprocket to 51, go a little shorter if needed.

your lack of low end grunt could very well be a simple as tuning. stock and even stage1 HD tune maps are very de-tuned with spark advance in the off idle, roll on and off the line pull areas. also the maps tend to run lean. Do you have a tuner like Powervision / TTS? SE255 cams or different?

 

I must of sounded like an idiot sorry. I do have basic mechanical knowledge of how it all works. I was simply saying what it feels like, and I should leave it as a stock ratio because smack in the middle as it is. The tune is great, that's definitely not an issue.
Or maybe it could be simply I'm use riding something with more power

 

I was thinking the other night I should just stick to a stock like ratio. Feeling like there's not enough top or bottom end, I'm not wanting to lose any more off either end to better the other. Thank for your help fellas, pretty much gave me the answer I was looking for, keep the ratio I've got

 

When you say not enough top or bottom end, is that the RPM range or the actual gear shifts?

My sport bike has a tall first gear to the point I am doing 75 mph before needing to shift into 2nd gear. My Harley has a 124" and it feels like a snail is passing me because I have to shift multiple times before I reach 75 mph.

 

Just feels like there should be another gear up the top on the highway. I wouldn't say it revs excessively hard but it does love the juice when in 5th cruising 110k/hr (roughly 65mph).

I might try the 23/48 as you suggested

Yeah I think Its just in my head having higher expectations jumping on the heavy slug

 

I felt the same way when I was running the 5 speed.

If I knew then what I know now (that is always the case), I would have went with a Baker OD6 or JIMS Fat 5 instead of the Baker DD6 and kept the front/rear pulleys stock.

Unlike changing a front/back pulley and effecting the whole range, the correct transmission change would have given me the best of both worlds. I could have a short 1st gear for better take-offs and still keep the rpms low during highway cruising in last gear.

I should add that my overall riding style (longer time between shifts) has changed since I started riding a sport bike since installing the Baker DD6.

 

Thanks buddy I apreeciate your help. I'll keep the OD6 in mind if this tranny packs it in

 

I have the Baker OD6 in my Big Dog chopper - for exactly the reasons described above. 1st-5th are short for good ratios in town, and 6th is overdrive geared. excellent combo. But let's not forget about the new DD7 too

Anyway, just like designing an engine, setting up gear ratios is 100% mathematics based. there is no reason to guess on the best setup if you use some of the available online calculators. I recall back when I was rebuilding the Big Dog from the ground up, baker gave me some excellent advice and guidance on selecting front / rear belt pulley ratio and primary ratio to go with the stock gearing in the OD6.

IMO, the gearing ratios on most 2006 / earlier HD 5 speeds is pretty much spot on, including the single gear overall drive ratio and the final overall drive ratio (which are the most important calculations). Ink83, you'll probably be fine sticking close to the stock ratio.

 

do you know what your rpms are at 65mph in 5th? I kinda know what you mean though, I go ride the Big Dog and then get back on the Breakout, it feels pretty pokey in comparison.
