Running in after new cct valves & shims

[dimesredbeard]

As title really guys my front cct exploded !! and took the exhausts valves with it .... head was ok piston etc.... i love my storm so got it repaired..... the mechanic said to take it easy for a bit as the new parts need to wear in ... how many miles you reckon??? And is it worth dropping/changing the oil in a couple of months ??

Any advice mucho appreciated

If it's just valves that have been replaced then there is no need to run it in as you would a new engine. It would be different if you had new pistons, but valves should be good to go. Just don't go thrashing the wombles out of it. But then that is not particularly good for an engine at any time. To be on the safe side just take it a bit easy for the first few hundred miles. If you want to change the oil then do so as fresh oil is always better than old, but there is no need to change the oil outside of service intervals.

Did you have new Honda CCT's or did they fit manuals. Honda ones will fail again at some stage. I suggest you do a stopper mod or fit manuals.

Some links regarding the Cam Chain Tensioners (CCT's)

Honda CCT's can go at any time, it's a gamble!
You can either go for the stop mod http://www.vtr1000.org/phpBB3/viewtopic ... 31&t=19416 Which is the Honda auto CCT's that are converted to a fail safe. So when it does fail, it don't send the valves crashing.
Or
You go for the full manual conversion, your options are here http://www.vtr1000.org/phpBB3/viewtopic ... 16&t=22720

I assume the mech didn't replace the guides?
If not, thrash away; it'll be fine.
If he did, then a hundred miles at less than full load and under 6K should be fine, a precautionary change at two hundred miles will be a good idea.
This is to get any particles that have circulated through the engine and will by then be trapped by the filter out and thrown away.
Obviously change the filter as well as the oil.

What did you pay, out of interest?

Cheers for the advice lads..... Guides were not replaced so all good there. It cost me 780 big ones but obviously labour was quite a big chunk of it. Gonna replace the rear tensioner soon as a precaution... I don't know anyone who would do the stopper mod but sounds like a plan to me!

I had some cash ready for hagon fork springs new fork oil and different sprockets 14 t front.... N some other shiny bits but I ll have to save again now !

so are you still on honda auto cct,s? cos as carl said they are likely to let go.

Jesus!
The parts are only about £120, if it's just two new exhaust valves on the front pot, a head gasket and a couple of shims.

It's only three or four hours work..... I'd have been happy with £250 all in.

But get the CCt's changed to manuals or stopper mod them soonest, before you have another big bill to pay.

Tony,
looks like you are under charging !!!!

Is a good reminder to anyone on the forum that you could save loads by
a) fitting stoppers or manual CCTs
b) if you ignore a) and do have a fail, then you should get the bike down to tony and give the money to him rather than some rip of garage.....keep the money in the family and save some hard earned, everybodys a winner
