Agree totally hilly, the variations in the numbers being posted are huge. There is a lot of generous dynos around these days that's for sure.
I love my stage 4 and am happy with it. Glad I have a good honest tuner who knows his shit, has a great rep and is also me mate... Even he finds some of these numbers questionable.
Specially when I see blokes running shit V&H short shots and getting over 120/120. I say bullshit
The kit gasket is already .055" , piston 6.5cc, too much for little old 54's.
Would like to see a current compression test. Anyone with Stg 4 here checked ? The Wood's are only $390, don't you like Bob's cams Hilly ? 777 are only .575, OK even for stock springs.
Thanks for all the advice guys, I must sound pretty silly, but I guess the stage 4 just doesnt suit my riding style. I love the bike, more fun than all the Jap, German, and italian bikes Ive owned over the years. The best bike Ive owned and this is my 20th bike. It has been dynoed at Pro Cycle by Fred and he is the best. The map M&W the dealer put in it was total shit and Fred sorted it out but I still enjoyed it more before the Stg 4. Fred is a really nice boke and knows his shit hey. He suggested the torque cones and also larger baffles and a retune. I like the new cam and head gasket idea. I dont really want to back build it to the stage 1, but if I did I'd have a stage 4 kit for sale only used by a little old lady to church and back.
PaulT can we see a pic with the scale ?
Hilly, not sure what figures your using ? I'm asuming zero deck
Thanks paulybronco, Yeah Im sure lots of people would love it, but I'd rather smooth bottom end power, Its sports bike quick above 4 grand. So what do you think would be a good Head gasket and cam combo? and I'll take it to Fred at Pro Dyno.
Get a Tman (nice cams with broad power range and quiet), S&S or Andrews cam that suits your present 10.5:1, get a 2;1 exhaust longer rather than shorter which is also smaller rather than big diameter, a smaller throttle body if it wll still fit (a bored to 50mm and well ported standard one or a HPI will out flow the harley SE 50mm and have better response). Big exhausts, throttle bodies etc etc etc are OK if you want to ride around at 4000-6000 RPM in first or second gear all day, try to resist the urge that bigger is better. Quick easy way to do it yourself and keep the costs down without having to take the heads off. Get your money back by selling the over the top bits on there now. If you want revs and power a second hand japa will do it better and not be much different in cost to what you might have spent just on the top end so far if a dealer did it all for you. Spend that much on modifying a jap motor which is half the size and see how fast it will go. At the end of the day it is a heavy bike with an air cooled twin cylinder motor not far removed from the first Harley OHV big twin made around WWII in it. NRHS I think it was did some dyno tests on exhaust cones and some other stuff, most of it is not worth the money, you might ever lose a bit of power. Still love mine as well even with all its faults.
Just my 2 cents.
I know it sounds stupid to go backwards, but the tuner said he'll put some nice cams in it so I'll be smooth and make the same if not more torque as the stage 4 did, and really, isn't torque in the real world where its at? Also this might sound picky but the high compression pistons gave the V&H long shots a real sharp note, I really preferred the deep rumble of the stock pistons. One thing, I took off on the stage 4 bike the other day and didn't give it the 4 hours the St 4 needs to warm up and left from a standing start from a tee junction and the bike popped almost stalled and fell over mid corner.
