Brands Hatch GP Meeting 9th/10th Aug 2014 - Entries
HI Fellow Thunderbikers,
As the annual pilgrimage to Brands Hatch GP circuit is almost upon us the BEMSEE team have reminded us of the need to get our entries in early
Currently Tracy has informed us that the Minitiwins and 400's are swamping the TB grid with additional class entires, whilst the clubs ethos is too give championship regulars first shout we are fast approaching the cut off point where extra class riders will be accepted and you will lose the chance to enter this fantastic round!
REMEMBER - You payment is NOT taken until a week before the meeting so get your entries in NOW if your planning to enter rather than holding back

The 2014 Season start draws nearer - Join the Fray!
With the 2014 season nearly upon us, most people are getting their bikes prepped and ready for the opening round of Thunderbikes now at Snetterton 300 on 26th/27th April. Thunderbike Extreme was a hotly contested championship last season with Steve Jordan and Dan Couzens trading paint for most of the season in an interesting battle between an inline 4 750 Suzuki and a twin 999cc Ducati in an aluminium frame. Both had multiple race wins and the Extreme formula proved that it produces close fought racing in the upto 130 bhp class. Jordan eventually triumphed and became the first rider to have won both TB and TB Extreme, he celebrated this achievement by growing a very silly moustache!
Regular Thunderbikes was also a tight championship, with Adam Nelson the 2012 champion on a Ducati 748SP fighting with Martin Cooper the 2007 champion on a Tigcraft 700cc single with various others making regular podiums. Nelson ended up taking the championship from David May as Martin Cooper missed the final round due to injury.
The 2014 season should see a great entry for both classes again with a good number of new rookies joining in the fun. With a large number of competitive riders in both classes we should again see a season of close racing across some of the great tracks that Bemsee have arranged for this season.
After last season grids we are again expecting a full grid to accommodate both classes, and some meetings may again have reserves so get your entries in quick to be sure of a place on the grid.
What are you waiting for? Come and join the most diverse and friendly class on the Bemsee programme.

Tech Inspection - What they are inspecting on your Thunderbike!
Mark has kindly let me lift this from his motoforum post and publish here as a useful guide on what is checked when the tech officials scrutineer your bike, it makes for a useful read whether your new to the class or not, enjoy!
As there are so many rookies starting racing this season it can be a bit strange at your first meeting going to Tech Inspection, what to expect, what are we checking for? Well this is looking through my eyes at what i'm doing when looking at your bike, hopefully it gives a bit of insight to what we do.
Technical Inspection ……………what the hell am I doing?
Most officials have their own routine but basically all will check for the same items
From here I will check the front wheel, Calliper bolts tight? No visible signs of brake fluid leaking?
I will now check that the oil filter, sump bolt and filler cap has been lock wired (some bikes also have dip sticks this also has to be wired) any engine breathers must vent into a collection bottle.
I will run my hand along the bottom of the fairing catch tray, this must be solid with no holes in it and constructed to hold at least half of the total oil and coolant capacity of the engine (generally all race fairings are designed to this spec) as well as the fact that any openings in the fairing are at least 50mm above the bottom of the fairing. If drain plugs have been fitted these must be taped in place from both sides.
Check left hand side foot peg has rounded ends, if standard ‘flip up type’ pegs are used hero blobs have to be removed. Make sure no excessive play or loose joints on gear shift mechanism. Side stand removed? (Yes it does happen!)
I will check the rear shock visually as well as the upper and lower mounting bolts, I will ensure there is no play in the wheel bearings or swing arm by forcing the wheel from side to side. Shark fin fitted?
Check right hand side foot peg has rounded ends, if standard ‘flip up type’ pegs are used hero blobs have to be removed, rear brake lever securely fitted and not fouling on any part of machine.
From here I will move to the top of the bike and check fuel tank/filler cap is securely fastened, give the rear seat unit a tug and make sure mounting is solid.
Assuming the bike passes inspection your card will be signed and a ‘Day Sticker’ affixed to your bike.
NOTE: Technical officials are here to get you on track, not to try and stop you. We will endeavour to be as polite and helpful as we can be to get you on track and to enjoy your racing.
Thunderbikes to use in the Thunderbike Series - Tigcraft SV650
Hello again Thunderbikers one and all, the third bike in our features on bikes to use in the Thunderbike series comes from the Tigcraft workshops in the form of Steve Parrott's SV650 Tigcraft.
A stunning piece of handcrafted motorcycle engineering, enjoy........
In 2010 Dave Pearce of Tigcraft fame built the chassis round the tried and tested SV650 engine, running GRXR1000 K5 forks and ’06 R6 swing arm.
The standard yokes were scrapped and bespoke adjustable yokes fitted with taper roller bearings. The rest of the front end has a Performance technology master cyclinder and brakes fitted to PFM ductile iron discs and a 16.5 inch front magnesium Marchesini wheel running a Pirelli slick.
The body work is from Replicast and is a copy of Hondas 2005 GP250 bike, this close fitting body work created cooling problems and a second delta shaped radiator needed to be fitted with an external electric water pump.
The exhaust system build by Mark Dent needed some thought as the rear swing arm was from an R6 and had no routing for a rear exiting V twin engine. The solution was to run a pipe from each cylinder, one exiting low and the other under seat and running a small bore balance pipe along the left side of the engine linking the two pipes.
The engine is bored to 700cc with some head work, race cams, and lightened and balanced bottom end, close ratio gearbox, slipper clutch and race alternator. Keihin flat slides look after the fuelling and the tank is a bespoke aluminium item. A light weight lithium battery proved inadequate to start from cold and the bike is wired for an external booster battery for starting.
The rear shock is Ohlins TTX and the forks run Ohlins internals. The rear wheel is a 17 x 5.5 Marchesini which allows a Dunlop 165 slick that was run on the original GP250 bikes.
