Interesting, I've never had a problem with starting. First time always.

The noise is gone now. Please refer to w/shop manual how to remove and install tensioner. Do refer to your mechanic if this modification is ok or not.
I have also looked into this. Certainly my spring applies pressure until the tensioner extends to the full range of notches (at 7,500 km my tensioner is on the 5th notch):



Applying a little more spring pressure to the tensioner with a small steel ball (would still retract to the 2nd notch) failed to take it to the next (6th) notch:



Failing with this exercise, I have ordered an APE manual tensioner.

My gen1 did it and my gen 4 does it I figure it must be normal. I have never had an issue and had over 26k on my gen 1.

Second place is the first loser:deathmeta

Your absolutely right. Gen 1 through Gen 4 have all used the same cam chain tensioner and the slap before stepping to the next notch is not damaging, just damn annoying.

I just installed an APE cam chain tensioner. All is well again.

Albeit the shaft was too long and it fouled on a nearby radiator hose. It required a simple modification and a new roll pin. I expect APE will fix this problem shortly.

With the APE tensioner correctly adjusted it is now purr purr purr purr and it is definately smoother at idle and low RPM.

With the chain tensioner tick you guys are hearing, is it doing that just sitting in neutral at idle? Does it increase in speed as you accelerate until somewhere above 4k rpm where you can't hear it anymore? I'm having the ticking noise in my gen4 too. Got used to it now, but I thought it was piston slap. It sounds like it's coming from the motor for sure.
Could someone possibly post a pic of the chain tensioner on theirs? -Thanks

I took my Gen4 out a couple of weekends ago and went flat out.. took it to the limit and stayed there for a few secs. I'm not noticing the 'tick' anymore at all.. weird? It still sounds / runs as great as the first day I got it.

Highway or track? What top speed did you get?

Been 140mph on mine for a short burst. After exhaust, PC, filter and dyno, I'm really going to test it. Really considering the flash too, even though already bought the PC5. Oh well, better tuning overall from what I hear with both anyway.

US-27 highway.. took it all the way to 189 before backing off. I'm hoping to do some mods soon: Leovince slip on, ECU flash, and PC5
