Just food for thought.
Eh Tutt .. Ya its me again
ya know how I feel on the topic my friend as it has been the talk of the town on many occassions not only on VTF but recently on HTT.
I cannot speak for the TC built after 02 as I am on a 00 but what I can say without any BS at all is the 00 has been solid. After 128,000+ Kms it still has 0.0005 on the primary side & 0.0015 on the cam chest side.
be running the 37G cams & the S&S gears.
I am not going to get into the advantages & disadvantages of gears VS rubbing blocks & chains based on claims without real past experiences. I can say if I have to eat the gears once it is up & off the tune table I would most certainly conceed to your dedication of the chains if I want to settle for second best.
I will admit I am just as dedicated to the gear-drive & the exact valve train timing to the mechanical poisition of the crank, rod & piston at any RPM that the gears offer as some are sold on the chains & blocks.
If someone can stuff a Gear Drive Setup into an 03 or later cam chest with a runout in excess of the 0.003 maximum which they state is crucial why is it then the majority of the sales for gear drives is allocated for the TC engines built after 2002.
There is also significant evidence that not all riders are willing to give into the thought that .003 is the limit yet they still continue to operate without any hitches Mile after Mile - Kilometer after Kilometer. The evidence is face-forward in posts on your thread not to mention countless others on both forums.
The key is that if gears present a problem with your engine why would anyone settle for chains. If money or Worth the Cost is your anchor in a perspective that puts second best against first place
I would have to ask why is this even a relentless topic. It is futile to consider especially when someone will spend 2800.00 on a set of wheels while the guts of the machine is running out of specs & settle for the nothing but the best for their engine. Better yet why would anyone even invest in a substandard set up.
If HD hasn't got the balls to correct their own FKUP I would never admit I don't have the wherewithall to correct it. I would eat hamburger helper for a month rather than run the alternative & spend my time trying to advocate that Chains & Plastic Blocks are cost effective
All anyone has to do is get geared uo for HD'S short-fall & get the engine running as it should have been done from the factory rather than buy Chinese clothing & chrome dodads on a substandard engine.
