Mallory park BSSO Test Day

Well... here we go...... the first track action for 2010!

The weeks prior to the Mallory test had been really hectic one way or another.  Unfortunately I had totally run out of time to do the intended new paint job.... but my good mate Dave Crampton's Gp6 was looking nice once it was all bolted together!

The big changes to the scooter for 2010 were all based around the new 2010 exhaust.  John Howe at Jahspeed has done a brilliant job with this new prototype design for Group 4!  It looks and sounds amazing.  Initial dyno test shows 2 HP increase and more torque...... although achieved slightly at the expense of a wide power band as its a bit peakier now!


The new exhaust is built around the engine and runs real close to the back tyre and will nicely warm the rear tyre ready for left handers!!  The engine now has direct air scoop for cooling (the aluminium cooling scoop was erm,... interesting to make!)  In order to allow for the scoop cooling I have a new cylinder head - large!!!!!!

Chalky White at Replay has remachined the combustion chamber to a new 2010 shape, and also machined down the mag housing to a bare minimum..... no cooling fan now!

So...............  following the initial run on a dyno it was time to get on track.  Finishing Dave's Gp 6 had been very much a last minute affair with lots of midnight oil being burnt.....  which meant we had to take it to Mallory having not even started it (more in a future update on the Group 6 bike)!  So once we had got there.... I proceeded to get ready to go out.......  whilst Dave proceeded to try to start his for the first time!





so.............  first session....... felt great to be on track and the new exhaust sounded great!  It was really cold so would be taking a while to get the tyre warmed up (Chris Geyton managed to bin his scooter at the second bend!)   .............  scooter felt good.....  but the new exhaust seemed to have changed some of the engine characteristics and although I had put in higher gearing than last year... it was not by enough as I was hitting 4th really early on the straight.

The first session was over all too soon............  as I pulled in Dave was still struggling to get the Gp 6 running as the clutch was permanently binding.....  decision was made to strip it and see what was up!

The second session seemed to come around really quickly and we were back on track.  The sun was out now and the track was getting warmer, so time to try a bit harder!  End of the session again came all too soon and towards the end there was just a little clutch slip starting.......

So adjusted the clutch and then checked on Daves progress which had been good and the clutch problem  seemed to have been sorted and it was firing into life!

The third session was just before lunch and the clutch slip was much more noticeable!  As was the gearing issue now I was getting more used to the power delivery of the engine.  I thought about stripping it to check the clutch and change the gearing but by now the sun had dipped behind the clouds and it was starting to get really cold.........  so opted to just adjust the clutch again and hope for the best.

Dave had now made it out on track and was enjoying riding the Gp 6 although gear change was an issue and will need to be modified!

Next session.....  I managed a couple of laps and then called it a day as the clutch had totally given up the ghost and there was virtually no drive at all!

So we spent an hour or so chatting and catching up with other riders and spectators, including Kieran Doherty - a world renowned photographer who is hoping to attend a few meetings this year to complete a photoessay on scooter racing.  Check out http://www.kierandoherty.typepad.com/kdblog/  and www.kierandoherty.com for his work.

The clutch problems will obviously need sorting out, but the exhaust seems to work well ......  I guess some new experimentation with gearing will be needed so I am hoping to do a couple of tests or track days to iron this out during the year.

First race is back at Mallory Park on Easter Monday .... 5th April........ looking forward to it!

Dragster Painted!

Well I started respraying Miles Dragster over Christmas..........   not exactly the best weather for spraying to say the least!  It has been a struggle to get the paint to dry and harden, even with a paraffin stove, a calor gas heater and an oil filled radiator all on the go!


The dragster has been painted in the fancy Ford Frozen White colour......  a very 'bright' white! Some parts are painted in satin black as a contrast and its almost finished now and looking quite nice





It took way too much paint to spray the scooter after I wasted quite a bit after initially using an incompatible hardener, and then managing to get a couple of runs on a panel, then in disgust as I stood back and cursed, I managed to knock a freshly painted panel onto the floor!  Much swearing and cursing and rubdown and start again!




Now its more or less done I can get on with the race bike!   Deadline looming....

ScootRs Quality

First off...... let me declare an 'interest'......   ScootRS are helping me out in 2010 with supply of an anti-dive kit, so there is an element of sponsorship to me for 2010.........  however.....  there is a debate raging across the forums over quality of ScootRs products vs some of their competitors!  >> http://scooterotica.org/forum/viewtopic.php?f=7&t=7313&start=20


ScootRs disc external disc brakes are the main 'benchmark' external disc in the BSSO race series, between myself and race team colleague Dave Crampton we have three ScootRS discs fitted to our race and road scooters and have always found them to be great quality.  Although I have now upgraded the pads used to EBC HH race compound, even the standard pads gave pretty good braking performance last year- until I wore them out at least!


I have noticed recently that BGM products have also taken a bit of stick on web forums too......   and I'm kind of linking the two brands together here.....   but ScootRS products may be manufactured in the far east, but in particular their disc brakes I have found to be of good quality, as are the absolutely superb BGM dampers..... yet there are people who question the quality simply because of the country of manufacture.  


I really don't think you can do this as a sweeping generalisation.  The UK can make some superb products and also some utter *&%$.  The global world we live in nowadays means that products can be designed, sourced, and manufactured all over the world.  The most important thing being the actual end quality / price - not simply the country of manufacture!


Its interesting to note that Apple products proudly display 'designed in California' on their packaging..... but where are they predominantly made?... ermm..... well your sparkling new Ipod or Iphone is finest quality product of China!


Sometime people like ScootRS get bad press over the odd product that is a 'cheap copy' .....   they have a wide range of products of varying prices and qualities........  but you pay your money and make your choice.....  but with regard to things like brakes....... you have to make a careful choice!





Its pretty easy to see from the pictures on the scootRS 'censored' advert that there can be big differences in the castings of different brands.  But I guess its just difficult to make that point without showing pictures of different products!

Winter 2009/2010 Rebuild


I thought I'd post progress over the next few weeks on the winter rebuild of the Group 4 race bike. Progress may be sporadic as I have two other projects on the go as well! But there is a definite deadline with the race bike so that will focus the mind!


Today I went down to the workshop at Replay Scooters - it was very handy to have use of the hydraulic lift in Chalky's workshop!






On the bench - mag housing removed







The old mag housing will be machined down to an absolute minimum for 2010 as engine will be upgraded to scoop cooling




mid transmission removal!  Race engine cases are never together long enough to get dirty!




Gearbox and clutch out!











It's always noticeable from this angle the different geometry of a race bike set up












A hydraulic bench makes it soooooo easy to work on the scooter!

So......   progress is started for 2010 race season.  Main upgrade planned is to convert the engine to scoop cooling.   This will involve a new exhaust system (££££'s!) and machining down the mag housing to remove all but essential material.  The cooling fans will be removed from the fan and a new - much larger cylinder head will dissipate heat away.   Final piece of that jigsaw will be a cooling scoop underneath the barrel to help channel cool air over the head and barrel.

A few other modifications will me made inside the rear frame section aimed at helping with cooling......

More progress as it happens!

Anglesey ! - The Wet One!

Anglesey...... wind..... rain...... sleet...... hail....... typhoon........ just a normal day in Anglesey it seems! Apparently it was sunny earlier in the year for a good couple of hours......

I really liked the Anglesey circuit last year which was the first time I'd been there (my second time on track). It's like the best features of a whole load of other circuits have been all built into one.... it's fab....... certainly amongst the top circuits in the country for sure.  It has a brilliant smooth surface, is nice and wide with a good variety of bends.... and a stunning coastal location.  Unfortunately this location is part of the downfall of the circuit as it is extremely exposed to wind, rain and fog coming straight in off the sea!

I arrived Friday night after the 200 mile journey and parked next to some dodgy looking multi-coloured fun bus. Turned out that this wagon was Darren and Wendy Glenn's latest aquisition....... it could only bring a smile to your face ....... and was pretty much a bargain. No indicators.... but hey .... can't have everything!


Saturday Race 1 ....... erm.... wet!  Fancy that!  I really don't mind the wet, I generally do a little better!  I had a good race and tousle with Mark Shirley and Dan Lewis and was reeling in Tony Rudd towards the end. Finished 13th which I was chuffed with.  It seemed as if no-one told Charlie Edmonds it was wet!  He was some 7 seconds faster than anyone else in the damp conditions!  Incredible!  He was trying out a new front tyre...... erm..... it works!




Race 2 was similar to race 1, except after lap 1 a persistent misfire crept in and gradually got worse..... I managed to finish the race but lost a few places towards the end as the motor cut out a couple of times...... hhmmmm water in the electrics?  Water in the carb?  Fair Chance




I managed to get the awning cover sort of secured between my van and Darrens funbus to try and get a bit of shelter ..... the awning had already been destroyed by the wind!  So I stripped the carb and cleaned it all out. Checked through the electrics and dried/cleaned everything through.  Unfortunately by the time I had done this we were past the curfew for running engines so I could not start it!  Fingers crossed for Sunday morning then!




Saturday evening had a lovely chinese from Holyhead.... mmmmmmm ...... and sat naughtily on the bed eating it!  Saturday might have been wet and wild outside but I was lovely and snug in the van...... never felt cold at all!

Sunday we started the scooter to try to make the sneaky extra practice, but it was a no-go...... misfired.... popped.... spluttered and died! Oh dear!  Another check of the carb, and a change of plug and all was well again!  Ready to go!

Race 3 was initially just damp, but part way into it the rain started to fall and the race was stopped after two people came off at the blind top bend.  As we stood awaiting the re-start the rain really came down..... well actually that's not true.... it went more across!  The start in the wet conditions soon showed all the oil on the track!  The dropped oil from previous races was shimmering on the water and it made it very hard to find a clean line!  Everyone was going very gingerly!  Despite this, my lap times were faster than the previous day and I had another good tousle with Dan Lewis as we reeled in Steve Pollit who was carrying the new BSSO onboard camera.  We passed him on the last lap and I went through a tiny gap down the corkscrew to pass him virtually on the rumble strip! 16th place across the line.

For the 4th race, conditions were drying a bit, but still wet and very windy which was quite unnerving on the straight as it shifted you across the track!  The formula had been set though, and it was another 16th place after another battle with Dan Lewis!

It was a good weekend of racing at this fabulous circuit despite the weather....... Cadwell Park is next...... the final meeting for 2009.
