Got back a while ago (just as the rain stopped natch!) and the worst of the
aching seems to have disappated so I thought I'd pop a bit down for those that weren't
there/couldn't make it/different continent/hemisphere.......
PB Track Day Rockingham 2/07/02
Well the day started well enough with blue skies and sunshine (but with some
clouds on the horizon). Promising I thought as I dashed around (really excited now,
just like Christmas as a kid) as I've never done a track day before..... Years spent
on test tracks at work but never on a bike!
Despite being closest to the track I managed to take a wrong turn (in my
eagerness to get there) and was dashing to make up time when a white van man turned right
at a roundabout from the outer lane. Strange feeling I thought as I careened round
the roundabout at 40mph bolt upright while leaning on the van door........... His
fault but he wanted to involve the police/insurance so I bunged him 50GBP for the paint so
I could get on my way. Damage? Scuffed lower fairing? Lucky? Damn
straight!
Made it to the track (less cash) to see the big Dent van right in front.
Pulled up and joined the throng. Loads there already. Great to put faces to
names (always fun and nice to *speak* to people from the list). Lots of poking
around bikes ensued and much dribbling over Mark's Monster (which after a little
persuasion he fired up which got some heads snapping round I can assure you!) Sounds
utterly amazing and believe me the dyno video does no justice to the crackle that
thing generates!
Normal briefings ensued plus photos of all and bikes individually. (BIG
thanks to Mark for stumping up my fee due to accident/lack of cash situation). What
with all that we didn't turn a wheel until nearly 10am. First job? Massed 2
strokes photo round the Indy Bowl at Rockingham (the only one in Europe I beleive)
Pyscho cameraman sits cross legged on top of a van with the baying hordes following
behind! (the cloud of smoke was cool!) You'll all be pleased to hear that the list
members were front and centre right behind the van. Actually that's not quite true,
at one point the guy in the van thought everyone was dropping a bit too far behind and
started waving us forward so Mark gave it a handful and gave them all a fright I
think! Sadly, one of the RG's blew a pipe a cooling pipe off during this low speed
parade (Paul? Peter? ) and my clutch was dragging like a b*stard so I'll not be
recommending Motul Transoil to anyone either!
Track sessions started shortly afterwards with myself and a few others opting
for the slow group. Nervous? I was shaking! Got out and settled a little
and gradually started to get into a rhythym before getting black flagged!!
Wha? Me? Damn, after all that I'd forgotten to remove the TI
kneesliders! DOH! Marshals were having kittens. Not to worry, despite the
obvious embarrassment of being the first (and I think only) person to be black flagged all
day the session finished shortly afterwards so not many laps were lost. New sliders
on, went to watch the inter session which was red-flagged after some one lost it
before the chicane.
Still no rain in fact sunny and warm........
The fast group was deeply scary (no flags tho') with some proper race bikes
present. Mark's beastie was not quite right apparently (it sounded like a genuine GP
escapee to me) and later inspection showed it to be running lean. That'll be the
320s then Mark? Jet? More like a hose!
I then proceeded to christen my new sliders in style (including the left thanks
to a great left hand double apex in 4th (.....) which is a first as for some reason I'm
not good at left handers) and had a great session and a cracking dice with a stock RG
(red/black/white and v.tidy) on stock tyres who was leaving black lines everywhere (in the
slow group remember). Got past tho! Spoke to him afterwards and he
wasn't even aware of the list........ He's buying a computer now just for the job!
The Inters had another session red flagged (!!!!) and the fast boys passed
without incident. Mark now happy with jetting....
Lunch meant more fuel and a visit to the ATM. We then proceed to deafen
each other by riding round to the track cafe helmetless. The infield has a long (300m)
tunnel under the oval to the outer buildings. I'm just glad I was in front as the
noise erupting from behind was deafening. RGs wake the dead? Oh YES matey!.
After lunch we organised what has to be the biggest collection of RGs I've ever
seen in one place for the website. Plenty of new members with a bit of
luck! I think we had about 12-15 bikes. Mark?
Lunchtime entertainment was provided by the scooter fraternity (NOs equipped
twist and go anyone? They weren't slow either) Unfortunately one of their
number decided that a helmetless/jacketless crossed up on the lock stop wheely landing
exhibition was required and managed to (I'm sorry to report) knock himself unconscious and
break his collarbone. Oh well, that many 2ts in one place meant some silliness was
unavoidable. The next sessions were then delayed while the sole ambulance dealt with
the fall out. Gave us more time for the photos I suppose.
Still no rain....... Threatening tho'.
Next session was easily my best with some cracking fun and a top chase (for
half a lap) of an R1 shod PB rider (fast???? Smooth was the name of the game.
Check the lines and strive to improve.....) Got some more left knee down time and
was catching 5th on the back straight, actually more of a long right hander
really (42 tooth rear) Right knee now taking a heavy pounding. Reported
(by one of the legion 350LC riders) to have been leaving black lines (wha? me?
REALLY? Cool!) His number plate was cool: "More seizures than
Princess Margaret" You've got to laugh.
Malcolm made his way home at this point. I'm thinking ( as the skies
threaten) was this the wise choice or do I chance my arm one last time? The bike
looks at me and I know it just has to be done. I'll be careful tho' I promise to
myself!
An interesting observation here: Very little stupidity, plenty of fast
but mostly sensible riding and I'm beginning to think that those of us that grew up with
LCs, paddock jackets, baseball boots jeans and Simpson Bandits have stayed with the
scene and are now in our mid30s and have mellowed (a little). I can just imagine the
carnage if this had been held in the late 80s....... In fact I have a PB in the
garage somewhere with just such an event and I think it was just that. Are we
getting old and wise? OK perhaps that's a little deep!
Rain was just beginning at the end of the last session and I was being ultra
careful (pushed my luck a little today) and the left wrist is starting to cramp so called
it a day and just cruised a bit. Keep the bike to ride another day....
Plenty of post session discussions with other RG riders re: all the mods
we all know about (these non-listers really miss out on a lot) Even obvious stuff
like the flame traps and rubber inlet silencer were still present. Needless to
say we all gave him the details that matter (www.edj.net and Mark's website) so we can all
turn him down the path to the RG "dark side"....... The Moskito ride
height adjuster was admired on various occasions despite being buried beneath the stk
rubber skirt (Thanks Mosky and Jim for selling it on). I can report that a 170 rear
on 5.5 GSXR rim with the 120/80 on a 3.5x16 front really work, with supersmooth handling
all day despite the stock rear shock. Got right off the edge of both sides of both
tyres. Thanks to all the listers who have provided bits for my bike which was stock
until you lot got me going..... I blame you *all*.
Thanks esp to the Maxton front forks from France (lister name lost!!! You know
who you are) which saved my ass on those odd "I really, really should be off the
brake and turning in by now" moments.
Fast session over it starts raining in earnest! Luckily, I've only a
20min ride home.
Needless to say it stopped as I got home. Stiff as a board and twice as
cold and wet! "Fancy a cup of tea" says Suzanne? Manna from heaven
I forgot to mention a nice young lady from Rockingham approached us before we
left offering pay as you ride track day sessions next Sat........ Mmmmmmmm I
think I might be up for that. Hooked now....... My polo shirt still smells of
Castor oil!
Speak to you all soon and rollon the September news stands as with a little
luck 4 Lister RGs will be front and centre on the front cover........

HI folks,
Well, after Ruaraidh's excellent review of his day i thought I'd add my 2pence worth.
Arrived nice and early (8.15am), spotted Mark dents van and parked next-door. After the
hello's and introductions Mark unloaded his bike and we proceeded to admire it for the
next 1hr. I was almost embarrassed to unload mine having only finished cobbling it
together on the Sunday evening, but the guys a couple of vans down wheeled out a rat
RGV250 that could have done with some serious tlc, so i didn't feel so bad. At this point
the bike had done all of 3-400 yards under its own power since built.
After much hanging around we eventually got onto the circuit for the group photo, as
Ruaraidh explained. And yes it was my bike that popped the hose. I was at the front of the
pack about 6ft from the back of the photovan. I suddenly noticed a lot of steam coming
from underneath me. A quick glance over the shoulder confirmed that i was giving the guys
behind an unexpected sauna. Oh the embarrassment, the shame of it. So arm up, and look for
a way to drop out of the group. Have you ever been in the middle of a pack of rabid 2
strokes and tried to make a stealthy exit, whilst trying to make out that every thing is
really under control ? In the end i just pointed to the bit of track i need for my escape
and moved over. People soon got the message and moved out of the way. So a gentle coast to
the pit entrance and hit the kill switch, i would have rode back to the van, but i could
feel her tightening up so decided a bit of leg power was the order of the day. Of course
everyone had returned to the pits by this stage and i received a few well intentioned
remarks similar to " Don't worry mate, you won't be the last to have problems
today".
One jubilee clip later and a few litres of water and we're back in business...or not. Turn
the key and nothing, no idiot lights no nothing.....bugger. A quick check revealed that
the battery -ve connection had come loose, By this time my group was already out on the
track. Never mind I'll wait.
Finally got to sample the delights of Rockingham, nice track, good clean surface,
good mix of corners from banzai braking into the two hairpins to a sweeping triple apex
right hander that you could really attack. Did a couple of warm up laps and then picked up
the pace. All the time feeling how the bike was behaving. Handling was very stable
considering the springing and damping were both shot. The bike tracked a very neutral line
with Ducati like stability mid corner. I wasn't pushing by any stretch of the imagination,
but this does bode well for future development. the 3.5" front and 6" wheels did
slow down the steering and I'm sure contributed to the stability, you could feeeeel the
bigger contact patch.
On the 5th lap of the session the bike started to bog badly. Just as if i need to use
reserve. I switched the fuel tap over and off she went, only to bog a couple of corners
later. The pit entrance was coming up so i trundled in. A quick glance into the tank...1/2
full. Ah, must be fuel starvation, but which part is the restriction. Check the tank
breather (ok), no kinked pipes (ok). Try again on another session. Exactly the same thing,
but if i cruised round on very small throttle openings for a lap or two i could then blast
for a couple, cruise, blast, an so on. I completed the next session like this, just
treating it as a shake down for the bike.
Nothing else failed or caused problems, so my list of "to does" stands at - fix
fuel starvation (probably needle valves), respring and re-valve forks, new rear shock.
Once these are done i can then start to ride it harder and see how she really behaves.
I managed to speak to Mike at PB about featuring the bike when it was finished. He was
very interested and verbally agreed pending the quality of the finish :-).
So mission accomplished, some miles on the bike, had a laugh with the listers, and came
home in one piece.
Cheers
Pete
