Power...Power, I need more power

[SJR]

Well, I have put about a thousand miles on my CSC conversion. It started out as a 2010 Ultra with the 96 c.i. engine. It was more than enough horsepower for me in it's total stock condition as a two-wheeler, but now at 1400 lbs plus, it feels a bit sluggish. It really only likes to be in the 2600 to 3000 rpm range and 6th gear is almost useless unless its a totally flat road or downhill of course. Starting at a light on an up hill grade is almost embarrassing. I'm glad I dont live in San Francisco.<br />
<br />
You guys have always been pretty helpful so....what do you suggest? I need me some torque for my birthday!

 

[clsimmonsjr]

I feel for you, but you will probably have to spend a load to get the power your looking for. A trike really takes a lot of power, Thats why I went with a goldwing.

After 32 years on a HD it couldn't touch a wing for power with a trike kit

</div>Hi looking for a quick help try the 30T conversion of the trans sprocket. It will give you some more low end boost. If you search this forum there are a couple of threades on the subject.

</div>Apart from getting the final drive ratio correct ( critical ) are you sure your fueling is correct ? Do you run a Power Commander or similar device. If not I will just about guarantee you are running too lean which = lack of torque.

I have a 2009 RoadGlide/Lehman conversion, with a 96" motor and a 6 speed.
This what I did, and it really does a fine job even in 6th gear.
BigSucker air, SE-255 torque cams, ThunderMax tunner, 4" SE touring slip on's, Jag 10 row oil cooler Rivera Primo clutch (i just dont like HD stock clutch).

It pulls 6th on cruise, and accelerates from 2500rpm, even up hill (am always 2 up).
Went for a little ride to day with the wife, 45 miles interstate up to 8,000 ft above sea level at 75 to 80 mph (i am at 3600 at home), then then another 68 up on top 50 to 60 mph, and 45 back down the interstate 75 to 80 mph.
37.5 miles per gallon, and it was 80 up on the mountain, and 105 at home.

My point to all this is the 96 the way i have it is equal to or alittle more hp and torque of a stock 103 that is in the tri-glides. It run cool as it can be, and the poer is fine, went to the Black Hills with this same set up, no issues good milage and runs just fine.

Hope this helps you!
Oh running stock gearing, have not changed anything there, and will not change it!

I'd switch to a 30 tooth transmission sprocket, the SE255 cam works well in the 96"engine, switch the air cleaner to a SE Stage 1 or a Arlen Ness big sucker. If your still running the factory head pipe I'd look at options to replace it. Then a tune is in order, I'm a fan of the TTS which will allow you to adjust for the speedometer change from the 30 tooth sprocket.

 

[1550vt]

Re-gear it....that's all you have to do. Follow the msocko3 directions and stick a 30-tooth sprocket on there....or have it done. You can spend all kind of money on engine mods and maybe accomplish the same thing, but it may still tend to be boggy in 6th. The Twin Cam was designed to run better in the 2900-3100 rpm range. The older stock 2-wheelers with the 5-speed ran real sweet at 3100 and 70mph getting 40-plus in fuel mileage.

Just as a test...forget you have 6th. gear for a while....don't even use it. The engine may feel like it's revving too high out there on the highway at 3100-3200, but it's not, it likes it. I just don't think you're in the power-band unless you can cruise it at around 3,000 rpm.

 

[SJR]

Thanks for the great suggestions. I am fairly competent mechanically but I don't think i'm up to getting into the transmission myself to go to a 30 tooth gear. I'm more apt to have the dealer do it and probably put on the low restriction air cleaner at the same time.

The service manager did see my trike when I was at the dealership and suggested going to a stage 3 build for around $2500.00

Maybe I will try the gear change and air cleaner,,,should be a lot cheaper.

 

[sportyharley]

I have the 2011 so pulley already a 30T.But free flowing air cleaner and swap out the stock header pipe made world of difference.Also cooled it down too.

 

[Oldmsocko]

As M3 said I would first change to the 30 tooth pulley and go from there. It will make a big difference in it self. A good fuel management like the TTS would be your next move.

If it's lean on stock gearing it will still be lean with a 30T drive sprocket. You cannot de restrict the inlet & or exhaust without changing the fueling unless of course you wish to exacerbate the issue in question and also introduce others caused by running far too lean.
Do it correctly & change the state of tune as well as the drive ratio & in this order.

CSC (I am assuming California Side Car) makes a gear change when they do the conversion. They use a jack shaft to drive a 3" belt to the final drive. That jack shaft is driven by the front sprocket, but it is changed out to allow for a wider belt and is geared to work with the jack shaft. So a change to 30tooth sprocket is not an option. I have a CSC kit on an 08 Ultra with a stage two 103 kit, Screaming Eagle breather, glass packs, Andrews Cams and a retune. I can keep up with any stock 103 two wheeler. This thing will pull in 6th gear doing 65. I really like it

The only gearing change you can make on a HD/CSC conversion is to change the tires (smaller for more power) or by changing out the motor sprocket. CSC uses a dual belt drive system and you cannot change the transmission sprocket. I built a good strong 103 and it still wasn't very good, then I changed the motor sprocket and it was like a whole new bike. All six gears became usable. I really liked the CSC after the gearing change, not so much befor.

Dwight

PS: you can also change out the clutch basket but the motor sprocket is much easier and probably cheaper.

Does the engine sprocket retain the compensator or does it do away with it?

 

[1550vt]

I HAVE tweaked the gearing by going to a little smaller tire. You may be amazed at what a 1-inch overall diameter in wheel size will do. You can get tires in all variations of aspect ratio. The only things you have to watch is ride-height and fender clearance. A tire 1-inch smaller in diameter will drop the ride height 1/2-inch.

I believe Hannigan also uses a double belt. I had a friend that had one and he was quoted 12-hours labor for a belt change. Makes me glad I always had a straight axle kit under me. Changing a belt on a Harley is enough trouble as it is.

 

[flynng]

So, On the engine sprocket change, you went from what to what. What year bike? Anything else you can share

Thanks

The change reduces the motor sprocket from a 34 (stock) to a 30. It does not retain the compensator. If I remember correctly it is an Evo Industries kit, it was a hot topic several years ago on this board.

I know the sprocket your talking about. IMO I wouldn't run without a compensator on a heavy trike, running without one does increase the risk of damaging the crank. I know of some guys who have tried them on their 2 wheel touring bikes and ended up taking them off and going back to the compensator because of the engine pulses being magnified.
