Due to the major differences in the height of the CBR1000RR engine that we are fitting, I have had to chop quite a lot out of the bottom of the airbox to get the bonnet on.

Can anyone recommend a suitable method of plugging the BIG holes. I have kept all of the plastic that i've cut out and have access to a plastic welder. Some form of flat sheet would be good. Would it be ok to use a sikaflex type sealer to seal some of the gaps.

It won't be tidy I know but it's only temporary and you won't see the ugly bit. Next year I will build an Aluminium plenum.

Would be good for the students to hear it run before they finish their Qualification.

I have to do something similar with the remains of my airbox. I am using a carbon sheet (aquired from work!) but any sort of fairly rigid plastic would do. Just make sure any adhesive/sealant you use is 'sensor-safe'. As they cure they can give off rather nasty fumes which can damage sensors.

Would you be better off desining your own bespoke box?

Buy a hot melt glue gun for a few quid, you'll probably get some sticks with it to do the job and it will come in for other stuff as well.

I will be making an air box in the long run, but I'm overseeing a group of students on the build (I've done most of it) and have limited time this term.

Good one I'd forgot about the hot glue gun.

I did wonder if sikaflex would be too smelly, but I'm not planning to run lambda control. We will during a mapping session though. Sensor safe sealant I havn't used yet but may give that a try too. I do have a big tube of windscreen sealant which doesn't smell when cured.

Use the traidsmans best friend, repairs and covers all sins...........
