Help me build a pissed off TC88?
I've got a stock 1999 TC88(a) with about 65k miles. It's time for cam tensioners so I figure I'll just do the whole damn thing.
I have engine assembly experience and really enjoy the work so I'm looking to put this together myself.
HOWEVER, I'm new to V-Twins.
That said, I like high-strung naturally aspirated engines and would like to turn up the "angry" factor on this little 88. Not really looking for a specific power figure. Really more interested in the character of the engine. Fast revving, choppy idle, wicked bark, drag pipes (regardless of their poor torque)....
I'm very flexible but right now thinking a 97-100", gear drive cams, head work, ignition, carb, etc. Not terribly interested in opening up the bottom end.
What should I do to get there?

All depends on your budget. After you figure the budget part out then you would want to look at where you ride the bike most of the time. By that I mean what RPM range do you run the engine in most of the time. Once those are out of the way it comes down to personal choice. You can keep it 88 and make a higher rev'ing engine or stroke and bore it and make a torque monster out of it.

Budget is flexible. I'll do it in stages if necessary. Maybe $5k (just for the parts)?
I tend run in the higher end of the rev range. 2500-5500. Lots of highway and back road bombing. NO stunting or antics and NO passengers. Ever.
Bike is quite light for a Dyna. 580 pounds wet. Chain drive, so I can alter the final ratio pretty easy.

5k for parts and no bottom end? For a little more money can't you go with a brand new v111 from s&s and have new everything and more power? Still get to do some wrenching too. Win win

Call Hillside motors for the calculation and level you want to spend...
http://hillsidecycle.com
Remember, while your in there check the run out to see if the crank is in tolerance for that added torque....
99was the first year of the Twinkie and plenty of options now...Fuel moto is another place that gives you levels of rebuild and support for your build..

Sweet. Personally I'd start with the crank if I built it.

Hillside bored my cylinders to 98" and ported the heads and intake. Went with a 585 S&S cam at 10.5 CR.
Very happy with this set up. Revs to 6K and seems to have power everywhere. You'll also need to change the ignition module so you can alter the timing as needed. I used the Twin Tech module, which Scott set up for me in advance to match my build. Stayed with stock carb, which seems to work just fine after proper jetting. I probably left a few horses on the table by not going to a bigger carb, but I'm very happy with the set up. Ended up with 95/106.
