Questions about front cylinder timing.

Hi all new to the forum, long story short I had my front CCT fail, pulled the head and found no damage to valves or piston, cam chain was slipping so bad it wouldn't engage the valves at all. As I'm putting the motor back together I'm wondering about the timing for the front cylinder. I have the flywheel at FT and am aligning the cams to the proper mark. My questions is since this is a 4 stroke had the piston is at TDC twice per cycle how do I know I am aligning to the correct one? I haven't touched my rear cylinder so I'm thinking I can use the position of those cam lobes to know when I am at the correct TDC. Thanks in advance!

Good question and you're right about using the rear cylinder to time the front cylinder. There's a copy of the shop manual in the Knowledge Base and an article there on CCT installation. There's another helpful article on www.vtr1000.org, the British VTR site. Read the manual and the articles and you'll have no difficulty sorting it out. You might consider installing manual CCT's while you're at it.

Welcome Shawn.
Please read the threads on manual Cam Chain Tensioners (CCTs).

So from what I can discern from the other thread is turn the flywheel until its at RT AND the cam lobes are upward and inward on the rear came, then turn 450 degrees counter clockwise to align with FT and align the cams to that correct??

Yes. See p. 8-21 in the Service Manual.
