Since the powers that be can't keep their hands off the rules, yet another edition of the GP rules was published recently.
Interestingly, they've tightened up the fuel testing spec (proper ISO procedure - I wonder what that was in response to) and added transgressions that receive penalty points (passing under a blue)
But of interest to this thread is the Moto3 engine rules for 2014: (Sorry about the colour and .... formatting, that was a Ctrl+V from the reg document).
In a nutshell:
6 engines per rider.
In homologated batches of 2.
Euro60K for the 6 engines, gearboxes and spares.
Max rpm will drop from 14K to 13.5K in 2015.
(My first thought....this is getting nuts. My guess as to why they haven't just imposed a spec engine a la Moto2, is that this is where lots of little Euro/Brit companies have slunk off to. Not full engine manufacturers, but supplier of rods, clutches etc)
Effective 2014
Maximum number of engines per contracted rider per season is 6.
Maintenance and rebuilding of engines by teams is not permitted,
except for one camchain replacement and one valve clearance
adjustment per engine. Engines will be delivered to the team sealed.
Each manufacturer may homologate a maximum of two engine
specifications per season. Manufacturers must supply all permanent
contracted riders with the same specification engines, the second
specification (if any) is intended for Wild Card entries only. Only
homologated engines and parts may be used in GP events.
Engine distribution will be controlled by the Organiser, with random
distribution to teams to ensure equality of specification, as follows:
Engines will be sold to the team and remain the property of the
team.
Manufacturers will deliver the 6 engines in three batches of 2
engines per rider, in a schedule approved by the Technical Director
prior to the season.
Each engine batch will be sealed by the Technical Director, who
will randomly select engines for delivery to the teams supplied by that
manufacturer.
The delivery schedule will also include sufficient spare engines,
as approved by the Technical Director (normally 50% of the number of
riders using that engine brand). Spare engines will also be sealed
ready for distribution as required.
The manufacturer may charge a maximum of €68,000 (excl.
VAT, excl. freight) per rider for the Moto3 engine package for the
season which will be comprised of:
o 6 engines
o 2 throttle bodies
o 6 gearboxes comprised of the two specifications “A” and
“B”, as required by the team
o 6 camchain replacement kits (if required)
For engine manufacturers in their first Moto3 season (when the
minimum supply number is 8 riders), the maximum number of
engines per rider per season is 8. These engines will be delivered in
three batches, minimum of 2 engines per rider per batch, in a
schedule approved by the Technical Director. In this case the
manufacturer may charge a maximum of €84,000 (excl. VAT, excl.
freight) per rider per season for the Moto3 engine package comprised
of:
o 8 engines
o 2 throttle bodies
o 6 gearboxes comprised of the two specifications “A” and
“B”, as required by the team
o 8 camchain replacement kits (if required)
Engine manufacturers in their first Moto3 season will be permitted
one parts/specification update prior to the second engine batch
delivery, subject to approval of the Technical Director.
In case of a proven, documented reliability or safety issue (eg. a faulty
batch of parts), a manufacturer may apply to the GP Commission to
allow replacement parts to be fitted to rectify the problem. If
approved, teams may not be charged, and engine power performance
may not be altered in any way.
Optional and aftermarket parts are not permitted, except for parts that
can be changed without removing the official engine seals. For such
parts the homologation, supply and price rules from 2013 will apply,
except in the case of a Back-Torque-Limiter clutch (BTL or Slipper
clutch) assembly, where the price limit will be 1,500 (excl. VAT, excl.
freight).
Effective 2015
RPM limit will be set at 13,500 rpm.
The supervised maintenance allowance will be cancelled, so sealed
engine covers may not be opened. Therefore camchain replacement
and valve clearance setting are not permitted unless these can be
done with the official seals in place. Manufacturers will no longer be
required to include camchain replacement kits in the engine package.
