'07 Advantages:

1. TC96 engine provides better low-end torque because of its increased stroke. In my experience the TC96 is also smoother than the TC88.

Cam plate has "native-metal" bearings instead of rollers, and this has not been a problem area. Many auto and MC engines have this bearing arrangement for cams and balance-shafts, and it is similar to sleeve bearings on auto and most MC crankshafts. Contrary to rollers, the bearing surfaces move on a thin film of oil provided by oil galleys in the cam plate. Inner cam bearings are larger (1" vs. 7/8") and oil pump has a higher capacity. Early TC's can be upgraded to the new cam-plate and oil pump, but this is an expensive proposition.

2. Cam-chain tensioners are improved with much higher lifespan. These are actuated by oil-pressure rather than springs. Early TC engines (TC88/95) require periodical inspection of tensioners, usually recommended every 25-30k miles. Later TC's don't appear to need inspections nearly this often.

2. Six-speed gives one more gear, but without IDS may be noisy. If IDS hasn't already been retrofitted it should be on the top of your list of to-do's.

'07 Disadvantage: Noise and vibration may occur if no IDS installed. Earlier models don't need it, so this isn't a disadvantage for '06's.

I may get flamed by early-TC owners, but IMO the '06 has no advantages over the '07 except cost.

The only weak spot in the '06 is the spring type cam chain tensioners that need a little more maintenance than the '07. The '06 motors run very well (that's very with a capital 'V').

I will do a bit more research on the IDS and it sounds like the 07 is a great choice.

One last thing....how many miles can I expect out of a motor before something major needs changed or serviced? i guess I mean like a rebuild.

No, that should have given him the advantage. Come to think about it my bagger outpulls another guys 88 Dyna and it's way lighter than my bike and I also outweigh him. The 96's I have seen run well. They all need the lean F.I. condition fixed. That's caused by the E.P.A.
