TW-6G cams installed
TW-6G cams installed
I got my bike back yesterday with the 6G cams in. To me this is what a Harley is supposed to sound like...Good potatoe sound, very little gear drive noice but I can hear the whine which personallyI wish Pete Jackson would make a noisy set, I love that blower whirl sound. Anyways, to me the bottom end is lacking 1k-2.5k but at 3k she comes to life and is very fun but I have to limit myself with the rising cost of gas on how much I can turn the whick up no a days. Here is what I have.
Stock 88 engine
SE Intake
PCIII
Rinehardt TD's
TW-6G cam
Fueling lifters
SE adjustable rods.
Dyno numbers are
81.83 HP
84.93 TQ
And from seeing the print out the dyno says the samething I feel, flat on the bottom and 3k she starts pulling hard to 5k. The tuner said the true duels hurt my bottom some and he could have gotten more out of it with a 2 into 1 but I'll give up a little for that.
Not bad imo for stock engine. I have a 95 kit for it with a set of heads that have been re-worked but I think when I go bigger I will get the cases split and do a 100+ build instead of the 95. I always look back and think I wish I would have done this so instead of going 95, just wait and go BIG.

RE: TW-6G cams installed
X....Tw6's generally require more compression to work well. I'm not surprised your bottom is hurting. The typical CR for the 6's is about 10-1. I wouldn't think they would be very satisfying on an 88" bike, but only you can say that. I've had them on two different bikes with compression at that level and I likeded them but found them very noisy, mostly valve train. Even at 10-1, Bob Wood reccomends his +2 degree tuning key which essentially knocks the power delivery sweet spot back 200 rpms.

Hardly sounds stock to me. [8D]
If it were me, I would throw on the 95" for the time being. You would get the compression where it needed to be for those cams. Wouldn't take that much to do it. Think about what GliderXXX said about the tuning key. A guy I know did it on his 95" Road Glide, made a big bigdifference.

Thought I would update this thread after putting over \\;3000 miles on it. \\; The more I ride it the more I like it and while I intially stated the bottom end seemed to be lacking I think what I was hoping for was more of the 3k RPM power down on the bottom end of it. \\; This past week we loaded the SG down with the tour pack and headed out to the outer banks. \\; We had her loaded down pretty good and i had the wife on the back and never once was I looking or wishing for more power. \\; The bike performed great and I think this engine combination is a very good upgrade over stock with the added HP and TQ. \\; I am sure after I up the cubic inches its going to be a lot better but for the money spent I am very happy with this setup.

Thanks for the updateglad you like your set-upthat's what counts.
 \\;
Also, I agree with you about not doing the 95" motor. \\; I have HQ-0034 bolt-in cams in my otherwise bone stock 88 '04 EG with Rinehart TD's and SE a/c. \\; And I ride frequently with guys with 95's ranging from SE Big Bore kits, Big Boyz street ported heads, etc. and they either are not as strong as my bike in the what i consider to be normal riding, or not significantly stronger to warrant $2-3K expenditure.
 \\;
On the other hand, a well-built 103" or bigger will absolutely walk away from methat added stroke translates into seriously bigger torque from roll-on. \\; So why spend money on cylinders and pistons that may not be compatible with a future 103"+ build, or have head work done for a 95" that may not be compatible with the stroked motor???
 \\;
So I'll wait till my 88 gets tired of haulin' my butt around and stroke itnow that will be like getting a new motorcycle.
