New fairing idea

The task is to loose this big heavy weight glass fibre fairing. Its too wide still even though I have tried cutting and pulling in but it still would deck out. A few kilos of weight too. I will weigh the bike once I have got the bike back to track ready condition!
So the task is to put something in its place. My initial thoughts were of some kind of bellypan so I dug out the original fairing plastic lower to see what I could do with that and perhaps graft a bellpan onto it.
This could be possible but would take too long, I have to make sure the extra bits cover the rear exhausts....too difficult!

So I went on ebay and bought a honda hornet acu race bellpan. I reckoned that this would do the job as the hornet has an upswept exhaust at the back. Looks a bit ugly, next make some simple brackets which can attach to one of the clutch cover bolts..easy job. 

Tried to get a snug fit, will have to layer the bottom of the bellypan with heat reflective tape, the exhausts dont quite touch underneath bt it will still scorch the glass fibre. Ive cut a small curve in the rear of the pan where the exhaust pipe exits the rear. Finally sizing up the top fairing, going to re-mount it with a slight angle pullin git up so it the side edges run along the top of the frame rather than the bottom.

Sold the GSA and have gone back to being sensible.

footrests


Made my adjustable re-sets out of 6mm Al plate, used an old cbr600fh footpeg hanger left hand side , much lighter than the vfr hefty item. Right hand side is vfr, just had to nibble out the frame where the rear footbrake master cyclinder bolt sits.

Battery Tips an at

Today I had half an hour spare to loosen the head stock as it was feeling stiff after the last race. After doing this it still felts tight so Ill have to do it again, might re'pack the tapered bearings with new grease. Got a new battery, the last one lasted a year but was rather cheap, not sure if the regulator fried it or I had'nt followed the initial instructions when I originally bought it. Apparently the first charge is the most crucial, its supposed to be trickle charged for 5 hours with the acid caps loosely fitted, then once off charge left for an hour and then push the acid/sealing caps down so they are flush with the top of the battery so to make a permanent seal. we will see.

changed front sprocket to 16, leaving rear at 45.

 Ive started getting ready for the next race weekend, missing Snetterton because Im off to Devon then, but ready for Brands GP. Been a long time away from the bike, still doing the bathroom slowly.
I've already removed the stator from the generator cover, it weighed a hefty 1Kg!....removed the regulator and heat sink plate that I made. Next removing the flywheel..I said good as done a quick job...unpacked my sealey all purpose motorcycle flywheel remover tool...good for 90% of all bikes......except HONDA!...anyhow I went to a 'nut and bolt' shop in Hersham got a M20 fine pitch bolt £3.00. Screwed it in holding the flywheel so it couldn't move and it just 'popped' and fell off...Flywheel weighed 1.5 Kg!

Im going to run a total loss system, free up the engine a little and loose hopefully 2Kg.
I'm also going to make some re-set plates just to  lift the a little higher, along with maybe doing away with the bottom fairing and making a small sump pan...got to slim the width down...or maybe paint the bike in vertical stripes.
