In the process of fitting my original one piece fiberglass bonnet/nose cone on to my zx9 powered strike. To get it to fit I’ve had to cut a hole in it and now my pipercross air filter and carbs poke through.
The carbs and air filter stick out about 10cm above the level of my bonnet.
Looking for a clean professional look so contemplating fitting a bonnet bulge to give me the clearance and finish I’m after
Any ideas
Been to see a fiberglass expert who suggested I look for a mold roughly the right size and shape.
Other option is to buy a fiberglass bonnet bulge and fit that
Any suggestions

Have a look at Honeybourne Mouldings they have a range of production car bulges replicated in fibreglass.

Will have a look thanks but not sure if they are going to be tall enough

Thinking of things I could use to make a mould
1. Small rooftop box lid
2. Plastic sledge
3. Half a kids hardshell suitcase
Need 10cm clearance so don’t think the off the shelf bulges will fit

I made one for my striker having fitted a crb1000rr fireblade engine. I new little about them when I bought it and realised I had to keep the upper injectors. I had to do away with the original air box but it was still fairly high and fashioned a mould out of cardboard and fibre glassed over it. I used filler to get it smooth but had to use loads so it is quite heavy. over winter I will take a mould of what I've got and do it again. Its bigger than I wanted but had no choice.

Thanks for the pics. Looks good. I’ve got a original 90’s bonnet so it’s even lover than yours. Running carbs that need still air apparently so need to be cover completely.

Make your own- it can't be that hard if I've done it! I made the two side bulges to fit my throttle bodies.



I used expanding foam to get the rough shape (cut with a bread knife kind of thing), then went over it with body filler and sanded it to get the finish. Then polished, applied release agent and made a mould with fibreglass. Once done I made the new parts in the mould.

Took me a while, but I took ages trying to get the two sides symmetric!

I'm in the same position but in my case I've got turbo poke through, I've decided to make some alloy trims to go around the opening

Found a suitable mould in the form of a babies plastic bath tub
Plan is to make the bulge then cut down to size.

Used a small babies bath tub as a mould and got my local fiberglass bloke to make me a bulge costing £45.
Trial fitted it before cutting it down in half height wise then going back to get the bulge fiberglass into position.
