What Makes Harley Twin Cam Years Worth Avoiding?
Harley Davidson with Twin Cam engines is stylish and fun to ride. But no motorcycle is free from fault & the Harley is also no different.
In the Twin Cam of Harley Davidson, the years we mentioned above show more faults than the others, making it suggestive for avoiding. Let’s check the reasons.
1999- 2002 Harley Davidson With Twin Cam
The main thing that makes Harley Twin Cam’s 1999-2002 years models avoid is the camshaft chain tensioners failure. It wore too fast then & the users have to replace its rubber shoes too frequently.
Apart from it, these are the early years of introducing the TC 88 engine. The engine appears plagued by issues & the riders face horrible engine failures.
In the 2000 models, the engine problems became so severe that Harley recalled the 2000 models.
2003 & 2006 Harley Davidson With Twin Cam
If you want to buy the later years, like 2003 to 2006, we will suggest you think again.
Because apart from the cam chain tensioner failure, these years also have had high crank runout issues. Riders face bumps and shocks, resulting in a poor riding experience.
Besides, the 2003 model is the first to introduce a six-speed transmission. Due to the massive transmission issue, Harley had to recall the 2003 models.
Now if we talk about 2004 or closely newer models 2005, the riders suggest avoiding the one equipped with DTP or Deluxe Touring Package. The DTP has an electronic throttle control system, so it is prone to fail.
Besides, some 2005 models have oil leak issues. Due to this reason, Harley has to issue another call for the 2004 & 2005 models.

Which Year Is Harley Davidson With Twin Cam Worth Buying?
Now that we discussed the worst years of the Harley Davidson Twin Cam, that does not mean all Twin Cams are identical.
Some years of the Harley Davidson Twin Cam engines have meticulous performance and are worth buying. That year can be 2009 or newer, like 2010 to 2016 of Twin Cam 103. It is because-
Better Engine Performance
In these years of Harley Davidson models, the TC 103 has a larger piston with a larger ratio of compression range. As a result, the engine offers more incredible speeds as the compression ranges between 9.2:1- 9.6:1.
The torque difference has also been upgraded these years than before. For compassion, we can see the Twin Cam 96 has 92.6 lb.-ft at 3500 rpm, whereas the Twin Cam 103 has upgraded to 102 lb.-ft at 3500 rpm in 2010 to 2016.
Oil Cooling System
Besides the Twin Cam, 103 has an oil cooling system which the older models do not have. As you know, a pollution-reducing catalytic converter can make the engine hotter, so Harley Davidson upgraded the oil cooling system from the TC 96.
So, from the discussion, ultimately it appears that the new engines come with high quality, better performance, and speed, making the older years, like 1999 to 2002, experimental & bad years, right?
