Horizons Unlimited - The HUBB - Rear shock too close?? Fiberglass airbox and rear "under-tail"w/battery tray...HELP

Hey guys!

I've been scratching my head for a few days now and I still haven't been able to fabricate a good enough airbox and undertail for my XT600 setup...

The first few attempts were a disaster... I think it's the type of resin.. it just won't dry completely!
It's always tacky plus it all just wasn't good enough...

So, I'm going in a different way this time.. here are some pictures...

Now:
1 - with the bike on the sidestand I got 21cm of clearance between the battery tray and the rear tire.
2 - with the bike standing upright I got 16.5cm of clearance.
3 - with me pushing down with my whole weight on the end of the frame I get about 9.5cm of clearance (with gear 120kg)

Should I go in a different way with the battery tray as it will give me about 10 cm more clearance and just make a small box to fit it behind the left handside plastic fairing (where it originally fits)????

Tomorrow morning I'm gonna buy some different resin and hardener and try it...
