here's a couple of photos from the first ride out.







the good news is that the bike runs and rides well and sounds fantastic... I couldn't help rolling on and off the throttle just to make it burble and crackle... childish but fun  :007:

First Track Day Done!









Finally got off my ass last Wednesday and did Cadwell Park, it was a bit last minute, so had no time to sort out the race nose cone. Ended up just whipping off the headlights and fitted the race seat unit.

Had a couple of problems on the day, first was the noise test ....
The nice man said "Give me 6500rpm" he got somewhere between 6 and 6 1/2.
After he'd stopped pissing himself laughing, he said "well done that's the loudest so far ... 112db".
after fitting the db killer I went back to throw myself at his mercy  "Hmmm it's just scraped through". That was a lucky escape!

After a couple of sessions it was pretty clear that it was over geared.
I'm running 16 49 at the mo and I could easily leave it in second gear from Mansfield all the way round to Barn. 15 tooth front sprocket is now on order.

After a couple of sessions one of the forks started to leak, not from the seal, but from where the fork tube meets fork bottom. I've never seen this before, so I'll have to strip it and see what's going on.

oh, and my expansion bottle didn't work too well, for some reason it didn't drag much coolant back into the system when it cooled down, so the bottle ended up full and the rad 1/2 empty... not good.
I've now fitted a Daytona expansion tank, so I'll see how that goes.

Even with a few problems, it was a great day.
Just need to fix the above issues and book another track day :002:

Sounds like it was a success how did it handle?.. Might be worth trying a new rad cap if its pushing that much water out,I have had the same problem with several cars,strange one with the fork leg maybe a loose bolt & I have a feeling there's an O ring down there... All in all worth all the effort you must be pleased with it

forgive me, for I have not posted any updates in months 









since the last update, the Dominator end can has been binned in favour of a LeoVince. fitted a new Ohlins shock, different tank and had the wheels and sub frame powder coated at moto-wheels.co.uk.  the powder coating only cost 120 and they did a proper job.
it did have a set of STr forks on for a while, but they were weeping from the foot / stanchion joint, so I've had to put the poverty forks back on until I can get the R forks fettled.

we're at Oulton on Wednesday, so I took it out for a quick spin..... I realised a few thing... I'm Fat, Old and I don't like the cold :003:

wrapped the exhaust because it was a slightly scruffy Ebay special + I was a bit worried about the amount of exhaust heat being blasted at the shock.
eventually, the plan is to have the whole exhaust system ceramic coated, that should dramatically reduce the heat and improve its appearance

Gotta say that looks awesome - not usually a fan of Daytona rear ends on STriples, but yours looks really good...and an absolute hoot to ride  :062:

                       ** Serious Update Alert ** 

I track day'd the bike like this for a year, but I was never completely happy with it



there was nothing wrong with it, it was good fun, but I just wanted that little bit more...
so I bought a Daytona, stripped all the goodies off the Street and put it back to standard ready to sell it.
I rode the Daytona at Cadwell, Oulton and Anglesey and it was faster than the street, but there was a problem....
it wasn't as much fun.

so I decided that FUN was more important that speed and switch back to the Street.
the plan is to try and make it good as I can make it.
so bring on the upgrades!!!

OUT with the STR forks and IN with a set of 2012 TTC spec Daytona forks.
it'd have cost over 500 to upgrade the standard forks, I picked these up for 330.
 
OUT with the Triumph Ohlins shock and IN with a Nitron race shock.
The Ohlins (ish) shock was only marginally better that the original and I picked up the 6 month old Nitron for 1/2 the price of a new one.

other bits I've done over the last couple of months.
removed all of the ugly brackets from the sub frame.
removed the casting seams from the triple clamps.
fresh powder coating for the wheels and subframe.
added some bits of carbon and titanium fittings.
added an HM dash.
fitted a new TRS bellypan.
and had the scruffy bodywork painted.

I couldn't decide on the colour scheme, so I had a play with the rattle cans to see what looked best.



these are some of the bits I sent





This was the end result
