Hi W@zza
my rear tensioner completley let go at 14000m no warning at all bent everthing cost me Â£500 at Wakefield Honda Leeds thing is its now at 16000m and due major service and i am thinking of checking the front myself as the rear is practicly brand new.I am just a little unsure about this and how do you if it needs replacing or should i just replace it anyway i have just done a mates nc30 valves but they are gear driven any help would be great thanks Alan

I'd bang one in Alan,
you know what it costs to have one fixed after they go (and yours was cheep compaired to some) and the front is prone to the same collapse.
All you need do is make sure the front cylinder is at TDC when you whip out the old one so the valve springs dont cause the cams to rotate.

Must have slipped Pete's mind, the cylinder you're working on does as Pete says need to be at TDC but it must be on the compression stroke and to make absolutely sure it is you need to remove the cam/rocker covers. If its not, when you remove the tensioner the cam chain will jump off the sprockets driving the camshafts, then you will have a big job on your hands

Yes my sons front one failed broke spring luck no damage, i got springs made , see my for sale ad, also tony wilde has a clever idea which is a failsafe , the spring is important as this ensures constant cam chain tension, solids yeh they cant break, but in my opinion all they achieve is putting the strain on the chain, so why risk it?

I think my spring and tonys bolt are a match made in heaven.

Good luck

There's probably hundreds of messages about CCTs on this sight, probably adding up to the most comprehensive set of ino. on possible whys and how to replace.

General view is that the fronts fail most often, some say thro' lack of lubrication. I changed the springs in mine at 12000 miles from some made by David Greenwood (see his Sticky - Sales and Wants I think). 1000 miles later I have no probs. When I changed em the front looked worse than the rear.

If I hadn't seen the add from David I'd have gone for the fixed type from APE (I think) - but then they look so simple I could probably make em.

Hi VTR owners - just found this forum. I didn`t know about the CCT problem. My 98 model had done nearly 18000 miles when I got a thorough service before departing on it to Spain for about 6 months - the garage did say the CCT`s would need checking for the next service and probably replaced and they had "knocked them in" as the chain was a bit loose. On the second day I was heading towords Zaragoza on my way to Barcelona for the MotoGP races doing a comfy 70 on an A road when I got the really loud clatterring sound. Got off the road as quick as I could thinking I`d thrown a valve, but it turned out to be the front CCT. Luckily I hadn`t damaged anything else apparently and 2 new tensioners were fitted, new coolant etc, 8.5 hours labour - 300 quid in Zaragoza - they even cleaned it, so I got off lighter than other people here!

If anyone wants to see my blog about my travels in EspaÃ±a on the VTR and whether there are any more gremlins, then check my profile.

Â¡Hasta Luego!

That's an interesting story, I think being able to take notice of any strange engine noise and acting on it pretty quickly is what it's all about with the Storm, although we have heard of some stories that conflict with that statement, if like yourself you are mechanically minded then that should be a bonus IMO

I was going to buy APE but couldn't wait so I made some. It wasn't difficult, but you need access to some machinery. Since done over 1000 miles with no probs

My VTR had rear CCT start making orrible noises this weekend. Spoke to my mate ( ex Honda Mech ) he reckons oil nothing to do with the problem but just a crap design.

None in country at the mo hoping to get it replaced next weekend. Appears to be the achillies heel of the bike.

Would seriously recommend getting replaced as soon as poss. Could be very expensive if it lets go. Bike now on 14,400 miles first time been done.

Apart from that the bike has been fantastic.
