Big inch motor question
« on: August 22, 2010, 02:20:42 PM »


   Im fairly new to Harleys, I used to have a V-Max (pipes and a jet kit) that you could let the clutch out at an idle and roll up to lets say 5 or 10 mph barely off idle and pin the throttle from a roll (NO CLUTCH) and blow the back tire off the bike! 2nd an 3rd gear too if you kept shifting, somewhere in 3rd it would get tration.

   I know this is the internet and all is possible...(grin) Is this possible on a (reliable) big inch bagger? I am being honest, not trying to stir the pot...I don't know thats why I am asking.


  I also have a 2000 Hayabusa 220hp 125tq on pump gas It wont spin off idle, the torque does'nt hit till high rpm, but downshift to second gear at 60 mph and if your not careful with the throttle it will flip you on your back and carry the front wheel through 5th gear touching down at 150-160 mph


   It seems to me finding out what a Harley V-twin is capable of is not easy. I can give you 5 websites for jap bikes off the top of my head that will tell you what engine combo works, what the hp will be, how much it will cost, pump gas reliable.

 I want to build my 110 but I am not going to take the plunge if I cant find a proven setup. You big inch guys what are your baggers capable of? Do they just pull real hard or can you spin/wheelie at will? any help would be great.

If you're looking for a big inch motor that has gobs of torque AND is as reliable as they come, go get yourself a Kawasaki Vulcan VN2000 - it has a 125 cube V-twin motor, pushrod, extremely reliable with loads of bottom end torque, with water-cooled heads (no overheat problems).  Not just my take, I have had one for 51K miles and have only had to replace a clutch cable.

CVO 110" with messaged heads, hi compression pistons, real cams, catless head pipe with 2 into 1 exhaust, 58MM TB Kit INCLUDING new injectors and heavy breather, tuner with custom mapping will get ya about 120hp - 130hp (quite possibly more) with about the same torque.  anything higher than this (IMHO) becomes unreliable and a bar hopper.  the higher the hp in the world of HD the less reliable and rider friendly they become. 

i just ordered my parts and hopefully in a week or so we'll get started on mine.  it's a new 2011 SESG and i'm doing the following:

- taking the current 110" CVO heads to stage 4
- TR 590 Cams
- TR Hi Compression Pistons
- V&H Dresser Duals
- V&H Hi Output Mufflers
- Tuner
- Mapping

the exhaust in my build is the wild card because true duals don't do well in the performance world.  i'm hoping to get 115rwhp and 120tq with this setup.  if it fails, i'll be going with the 58mm TB complete kit as well because i don't like 2 into 1 exhausts on baggers.

her's a video for ya if you think baggers are unworthy........

here's an example of a proven package  http://www.tmanperformance.com/gallery110_4.htm

The 110" engine can be brought to powerful level, and a 117" or 124" is even more so.
All can pick the tire, and all can blister the tire as well.

As mentioned by Don (Deweysheads), making big power without upgrading the bottom end will probably be a serious mistake.  The current Harley crankshaft is a weak link, and I wouldn't invest all that time and money on the top end without fixing the bottom end first.  And don't forget the primary components, the weak clutch, and the marginal trans. 

If you really want crotch rocket performance with reliability, I suggest you stick with one of the excellent products from Honda/Yamaha/Suzuki/etc.  On the other hand, if you don't mind breaking stuff all the time, then by all means go for the big numbers on your Harley.  Probably be a good idea to have a chase truck when you go for any long rides, however.  Like tennisman mentioned, it's a touring bike, not a racer.  Since you are fortunate enough to have a touring bike and a crotch rocket, it looks like you just need to decide in the morning if you prefer to cruise in comfort, or go out and burn up a tire, and then pick the appropriate bike to take.

Thanks for all the replies guys, i wasnt downing baggers I own one, and I don't want it to be a crotch rocket. There is some thing cool about a bagger with gobs of lowend tire melting torque, I don't tour the country...yet, I do ride on weekends and sometimes with some cocky wannabees, me and the ol lady two up on a bagger leaving a solo hero on a softail in my wake is disneyland to me! A picture is worth a thousand words. Thats all I was really looking for.

     I decieded I am going to drop a couple of teeth on my primary sprocket (I have the -1 tooth belt) and stick with the Fullsac Xpipe, 2" baffles and TTS tune that I already have and make the best of it.

     I only have 5k on my 09 SERG, I"ll run it till its tired or something breaks...then all bets are off!

I'm running a 124" engine in my 04 SEEG and take it on the road all of the time without any worries.  Very reliable, no hotter than my 103, and gobs of power and torque throughout the power band.  The dyno sheet is here: http://www.cvoharley.com/smf/index.php?topic=162.msg733865#msg733865

As you can see, 125 ft lbs @ 2500 means that the bike is a LOT of fun!

Well ( I took the advice)----------I went and looked at crotch rockets......didn't like the bikes but I sure wish I could find one of these stands ! !

Jerry, that comment reminds of a person we haven't heard from in quite some time.  Has anyone heard from Hoist?

It seems like no matter what he did with the '07 SERK he had issues.

I just haven't seen his postings lately and have been going back over old threads and there he is with his bits of wisdom for everyone.

God I miss that guy...  :P  :P  :P
