Chewed trumpet screw

[VTRLichtie]

Finally, after owning my Storm for 4 years and reading this forum I decided I need to do something about the CCT's
I started stripping it last weekend, got as far as removing the inlet trumpets in the airbox and one of the screws will not come out. I eventually wrecked the head on it. A couple of questions - I am thinking of drilling the head off, very carefully. Does anyone have any other ideas? Also, if I get it out where can I get another one? It looks like a bit of an oddity and I would like to replace it with one the same.

I have managed to pick up an old pair of CCT's just to find out how they work. According to Haynes you should be able to push them in but they don't move. Is this another of Haynes myths?

can you use a dremel to cut a slot accross it and use a flat blade screw driver?

drilling out is very difficult

[Diabolus]

mabey get a dremel in there

(took pics for reference when I did my ccts)

i've got a couple of those screws mate, send me your address via pm and i'll send them to you fella....

If it's the rear one, you can also get a junior hacksaw across the chewed head and undo it with a flat blade screwdriver.
Screws tend to go with the trumpets when sold, but Honda won't charge more than a couple of pounds.

It's worth getting the correct ones as they fit neatly into the plastic, trapping them if they come undone, and stopping them falling into the engine and wrecking it.

And a tip:
treat crosshead screwdrivers as consumables, and throw them away and get a new set every so often.
Cheaper in the long run than wrecking fasteners.

I know, hindsight and all.....good luck.

Same happened to mine the first time I had to get the airbox out - and I successfully drilled it out,

If the dremel doesn't cut it ;)

Pack both trumpets with rags so no crud can get in!

Centre punch as best you can the centre of the mangled screw head

Come down as straight as possible, then progressively increase the drill bit size as the objective is to remove the screwhead leaving something for grips to grab hold off to spin the remaining thread out. Hoover and mop out the swarf so the airbox is spotless. On reassembly I replaced all the screws with hex heads.

if you bugger a trumpet i might have one of those aswell as the whole bottom of the airbox, so even if you rock it up you can have mine for the cost of postage mate.

Thanks for the replies, I have sent you a PM Marty.

You are right Tony, hindsight is a wonderful thing and it was an old scewdriver. Didn't think they would be so bl**dy tight!

I'll have a go at cutting a slot in it and let you know how I get on.

[Wicky]

Tight cos they (rightly) loctite them in so as to stop any chance of them working loose and getting sucked in!

[tony.mon]

Those screws Marty is holding are some of the set of eight that hold the lower airbox onto the carbs, not the ones that hold the trumpets on.

bugger!!!!!!!!

If it is the airbox screw and not the trumpet, I had the same problem, they are made of cheese! I carefully used an impact driver to remove it. It's tempting to replace with allen head screws an locktite, I will do that next time unless someone says that's a bad plan!

[VTRLichtie]

Finally got round to doing something about this today. After plugging all the holes in the airbox I attacked the screwhead with increasing sizes of drills until eventually I managed to jam a flatblade screwdriver in it and out it came.

I ordered a replacement screw from David Silvers which turned up within a week. I now have a couple of spares so if anyone is looking for one get in touch.

Where is the best place to get manual CCT's as I think this is the way to go?

p.m bazza or rideronastorm i think is his name, they both make and sell cct's.........
