Happy bunny

Danny Imberg - 1st in class in MRO Stocksport 600 at Brands Hatch this
afternoon on his Daytona 675.

Lozzo - had the 675 in a million bits yesterday and this morning
sorting a misfire and then an overheating problem.

I are a very happy bunny, that's the first win we've had on the 675.

Glad you made it. Great result.

Good lad!

I thought you'd gone quiet as pig flu had got you.

Well done on both counts.

 

Nice one.

 

Well done you.

You know this old BM I have. . .?

Hey Lozzo, Don't exaggerate.... the 675 only has 276,172 bits to start
with....
Approximately!

Well done _that_ man! Good on yah! )

I'm always happy/amazed when that happens ....

Paul.

 

congrats on a job well done.

There were approximately 30 bolts left over...

 

Coo, well done. What went wrong with the bike?

 

Hey, always handy for spares ...

Very well done.

 

The misfire was a blocked 'tea-bag' fuel strainer in the bottom of the
fuel tank, which means stripping the pump right down and cleaning it
out. You can't see it even when the pump is out of the tank, and I
wouldn't have known it was there had I not been told as it's completely
hidden.

The overheating problem is something that often happens with hard raced
675s, they don't quite flow enough water to cool efficiently, but they
need some kind of restriction in the flow to ensure that any cold water
flowing through does take heat away with it. The problem is that if the
thermostat is removed completely, the metal bits run even hotter even
though the gauge shows cooler, because the water is running way too
fast to actually cool anything and is still quite cool when it hits the
temp sender. The cure is to drill a series of 4mm holes around the
circumference of the stat and then replace it in the bike. It's a
common mod done to quite a few 675 race bikes. Not all of them run this
hot normally though, so you don't know it needs doing until you're
running at top level.

I've a feeling the bike may well have overheated once too many times
before I did the stat mod, as it chucked water out of the header tank
over flow pipe and all over Danny's leg on the final lap of the last
race. it looks like the head gasket has blown and the cylinders are
pressurising the cooling system.

Bloody well done, mate.

What are the engines like, in terms of build quality, inside? Good
stuff?

Oh, well done, btw.

 

heh. Me too

 

I've not had this one down any further than throttle bodies off,
thermostat out etc. There's a lot of plumbing and electronics under the
tank, but it all makes sense once you've done it a few times and things
don't break easily. The only thing we've worn out is the dry-break clip
from fuel pipe onto the tank, and even that doesn't go anywhere once
it's cable-tied in place. It's never needed any proper engine work in 3
years of racing[1]except for shims and they were done before Danny
bought it so we've left them alone until the end of the season. Overall
build quilty of the rest of the bike is top notch, the finish on the
frame and cycle parts is incredibly tough, because we haven't managed
to scratch it despite lobbing bare metal ratchet strap hooks over the
tubes time and time again, and then pulling the bike down tight in the
van.

Thanks, it's nice when it all comes together right when the thing has
been spread all over blankets on the pit-garage floor all evening and
morning.

races, and now Danny running it in MRO Stocksport 600s against a load
of British Superstocks kids with Daddy's money to crash and burn.

 

I've read of a few people busting off some part of the plastic fuel line
from the tank (pump outlet?) resulting in having to buy some rather
expensive replacement parts. I only had to lift the tank to fit the
snotoiler, when/if I need to remove the tank completely I think I need
to be uber careful.
