Low & slow

In January 2014 i had 22 meters of T45 tube lying on the cellar floor. 1 year and 8 months later and it's been transformed into a race ready bike, and on Friday were headed to Shakespeare county raceway to run it for the first time at the Open sport nationals.
We'll need to do a handling run or two but with the engine, nitrous system and electrics straight off the old bike we should be able to put a bit of power in once i'm happy with it and try to find a setup that works.
There's now 7 bikes on the entry list for Funnybike, so that could mean a nearly full 8 bike field, but we could still do with another bike or ten turning up! Qualifying is on Saturday and Sunday, and eliminations on Monday. will be covering the event as usual, the event page can be found here:…/2015openspo…/default.asp

It runs ......

Had the bike outside, fuelled up and checked for leaks etc, and fired it up this weekend.
Dead pleased with the way it looks, it's hard to visualize when you build it in a small space and can't step back and see if it looks ok. Ran well, and everything seems to work. It's very nearly ready for the Open Sport Nationals at Shakespeare county raceway in 2 weeks time.

nearly done

Bit more progress with the paint job. 2 rolls of fine line tape and 4 rolls of masking tape later ....

A lick of paint

Made a start on painting the new bike at the weekend. It took hours to mask out, and there's 3 more colours to go yet!

Some stainless tigging.

Some months ago i picked up a used but very good condition - full stainless Vance & Hines pro pipe exhaust. I wanted it for the new bike as my current one is rusting badly from the inside out.
I guessed it would need some modification to fit my chassis as it was off a prostock bike with narrower frame rails. And when you buy them new they come in several pieces and you have to finish them yourself. It's a real nice system - wafer thin and very very light. Anyway, i had to hack saw it in two and add extensions to the headers and a 2 inch section to the downpipe to make it clear the frame. I'm not a very accomplished tig welder and it's particularly tricky welding such thin material, but I've just about pulled it off i think. I want to ditch the megaphone section for a narrower straight pipe. Will ask a sheet metal place to roll me a tube out of wafer thin stainless sheet i think.

Due largely to a lack of time I've decided to fit my current engine into the new chassis as is, and chosen to save the bigger block and head till i have more time. It also means i have less to test at first, making the transition simpler perhaps.

I've managed to part with all the Lectron WOT switch / carb tops i made, several fellow racers had requested them and I'd left myself without on e... again! So I've now done a CAD file and am having another small batch waterjet cut. It's a slightly different design but is less wasteful, and more accurate to produce. I'll just finish the cut parts on the mill.

I had the front wheel blasted a few weeks ago too. The wheel is Cagiva Mito 125 and had spots of corrosion and some small pitting. I tried to clean it up but it was going to be  alot of work. Anyway - £20 to have it blasted and it's come up brilliant. Too nice to paint almost. But it's been painted black already ..... before it starts oxidizing again.

Lets build a dragbike

I've started on the final build of the new bike. The downside is, I've been pillaging bits off the old one and it's starting to look a bit sorry for itself.
Bodywork is now in white primer awaiting masking out and a nice day to start getting some coats of paint on it. The plan is still to try and have it ready for the next meeting at the end of august. With bits now removed from the old bike there's no going back really.

Yesterday i finished this dashboard/surround and switch thing for the Nitrous controller. It doesn't need it of course but a good example of waterjet cutting put to good effect once again! It took me maybe an hour to design that file and probably 1 minute 48 seconds to cut it.

Top fairing is Ducati 848/1098 but modified a bit.
I also fiberglassed a tiny part of the sidepanels to it as it didn't look right otherwise. I just bought some scratched panels off eBay and sawed the scratched bit off.

Not the summer Nationals

We didn't make it to the summer nationals last weekend. We set off and made it just past Manchester when coolant started leaking into the passenger footwell, not dripping but a full-on flow. I managed to get it home by topping it up and pouring in yet another bottle of radweld, but the heater matrix now
definitely needs replacing.

The frame for new bike is now 100% finished and has been coated with 3 coats of a clear rust inhibitor. It's not getting painted, it looks great just as it is.
