FASTEST PRODUCTION BIKE ON EARTH
« on: September 04, 2017, 08:08:31 AM »
We went back to Loring to enter the 2000 and 3000 class up from last yrs 1350 class. We had a 10mph cross wind all day which I sat out most of the day. I decided to take a safe check out pass and was sideway the whole run and ran 199 in the mile on a 155 record and a 203 on a 205 in the 1.5. I waited until close to 6pm to make my 2nd pass and ran 210 in the 1 and 214 in the 1.5 to take both records. We came back Sunday with predictions of 213 and 217  1.5 but I ran 217 mile and 219  1.5 with maybe a 2-3 mph tail wind. I decided to make 1 more to seek 220, but during all the passes I was experiencing the front end dancing side to side under acceleration in the lower 3 gears and I was after it very early to seek 220, well my eyes were distracted off the tach because of this and  went into the limiter hard in 3rd almost to the point of aborting the run. I recovered fairly quick and pinned it as fast as i could to atleast get a decent 1.5 speed. I was going throught the 1.5 traps higher in the revs then my previous 3 runs so I knea it had to be pretty decent. I got back to the truck and told my buddy I screwed up that pass. He said well you didn't screw up that bad you went 220 + !!!  And 217 in the mile. I told him if I wouldn't of hit the limiter I really think I could've went 220 in the mile and 223 in the 1.5. I decided to call it a day until I settle the front end down with a nice Scotts dampener.   Thank you Larry Forstall for this opportunity.   Whats next? Will see. Many different options to choose from.

Absolutely outstanding!    I think no one really appreciates those speeds until you actually run in Production class.  Incredible!

Production Class.  The bike "looks" exactly stock, except for safety stuff, all modifications are "hidden" from the eye.  Stock fairings, stock tank, stock ride height, even stock exhaust (what you can see that is).  Your suppose to have a picture of the bike from the manufacture for comparison.

Has to be a handful to drive that 1700cc monster at stock height and length. great job!

Question, is a modified header(or aftermarket) with stock mid pipe and can legal? i mean you can peek into the fairings. how picky are rules on this sort of thing? im thinking about doing a smaller cc production bike with a buddy.

I can't answer for all situations, but I would guess if it is obviously different it could be protested.  I know on a Busa you can see the step headers on some exhaust through the fairings, but a slightly larger h  eader painted OEM black you really can't tell.  The big difference is the cans must look stock even if you look down them....

So, you cant open up the cans if it can be seen from the tip. Must be a pain to tune that kind of motor.

You can gut the cans as long as they are stock appearing. You can tell by the sound. Our stock exhaust is the same one used at Bonneville which is the most scrutinised venue in LSR.  There was a bike that had the ends drilled out and went 212 in July that was also lowered. We also use OEM airbox and OEM ram air tubes. I personally dont agree on the  .5mm overbore allowance. Yes its a handful riding it and foot shifting without the aid of a quick shifter. Would the rules allow a Scotts dampener to be added? I feel I needed one or the stocker worked with thicker oil.

What you mean this little old 1999 stocker.  :huepfenicon111:   It put me in the 2 Club in 2000  and Mark went 220 one way for a 217.9 record in 2002 that still stands. LSL

So it a 1679cc motor in there, right ??, Production you say ??

SCTA Rules, section 7.J.1 states:- "OEM engine ""displacement"" determines the displacement class for competition. Displacement "may not" be increased beyond that class limit,,

1999 Hayabusa, 1299cc, which as a Production bike "locks" it into 1350 class,  :?

I congratulate you on the speed attained, however, although the bike looks innocent as a Production class bike, Suzuki did not produce a 1679cc OEM engine package in the Gen1 Hayabusa,,

I would argue that a Scotts dampener would be a safety feature and should be allowed. I started to state earlier that you need to swap out some heavier oil in the dampener after seeing all the shaking going on....

The 0.5mm overbore rule was removed from the Production class a few years back.

Yes I'm aware of changing the oil in them. I just didn't do it to this one. Lets all be thankful that I didn't.

Scott, last I checked they don't make any 2000 or 3000 or even an inline 1650 cc Prod bikes. If ECTA and LTA offers these  classes then we will take advantage of it. I mean the class is there, what am I suppose to do not enter it? Or because I'm worried about what people think. I never said I have a 1300 cc motor, I have a 1679 in a 2000 class. Technically I could run 2000ccs. Everyone is invited to give it a shot right? What about the records I broke, theirs are ok because it only 205? Look in the book the classes are there in print with records attached to them. I broke them. If I didn't break them and especially go 220 everything  would be fine? Btw I have been running this type of Prod bike way back in 06 and 07. Same big engines same classes!!

Scott didn't question the class/displacement, I did,,

I have stated in the post what the rule says, I have nothing to justify,,

My bad, but even the 1650 class, do you think those records are held with a bike thats 1300, 1400 or 1441 cc motors? No they are built motors up to 1580cc that I've seen on a zx14 motor application. If it was meant to be stock displacement why not have a P/P 1300 class, instead its 1350? So now its a built motor up to 1350cc. We're not claiming worlds fastest stock motor Production bike, just the fastest speed recorded in any type of Prod class at any venue but in the designated class we happen to fit in and we're damn proud of it !!! Its stock height, stock seat, stock modified exhaust, stock throttlebodies, stock airbox and ram air tubes, stock wheelbase down to the bar-end weights. Its not like I entered the 1650 class even though I could go the same speed with 1634 motor. You also are referring to SCTA, we are racing ECTA and LTA venues.

I just grabbed this from the lta site

7. MOTORCYCLES
MOTORCYCLE OVERVIEW
Motorcycle records are kept in 6 Categories:
OHC (Overhead Cam), Pushrod, 2-Stroke, Twins, Classics, Electric

B: Modified Class motorcycles with custom APS fairings fall into APS.
SIDECAR (SC)
A: Modified or Altered class motorcycles with a sidecar attached.
B: Riders are not permitted.
STREAMLINER (S) AND SIDECAR STREAMLINER (SCS)

in motorcycles in a volume of 500 units.
NON-MOTORCYCLE ENGINE DEFINITION
A: Engine originally designed for automobiles or non-transportation purposes.
B: Motorsports engines not sold in motorcycles in a volume of 500+ units.

51
PRODUCTION – (P) For all engine classes.
Production engines must be the same model as the model of the frame being
used and must have STOCK EXTERNAL APPEARANCE with OEM cylinders,
heads and crankcases. OEM engine displacement determines the displacement
class for competition. Starter must be retained and operable. Carburetors or
throttle bodies must be OEM for that model production engine. ALL
PRODUCTION ENGINES RUN IN GAS (G) CLASS.

VINTAGE – (V) For all Engine Classes except Classic.
Limited to motorcycle engines produced prior to 1956. Non-OEM cases and
heads allowed so long as dimensionally equivalent to OEM.
2-STROKE (/2)
Defined as an engine operating in a 2-cycle fashion.
A: Motorcycle Engines Only - Production and Modified Frame Classes.
OHC
An engine with overhead cam operated valves as defined below.
The camshaft location must fall within the following limitations:
A: Above the valve train.
B: No more than the crankshaft stroke below the OEM cylinder deck.
C: Pushrod length less than twice the crankshaft stroke. (BMW air/oilhead.)
PUSHROD (P)
Any engine with push rod operated valves as defined below.
The camshaft location must fall within the following limitations:
A: At least one crankshaft stroke below the OEM cylinder deck position.
B: OEM pushrod length at least twice the crankshaft stroke.
C: Replacement heads must have the same number of valves as originally
produced for engines of the same series in Production.

water spray, radiators, enlarged or modified oil systems.
E: Fuel system may be upgraded. OEM carbureted to remain carbureted.
F: OEM fuel injection may be retained, modified, replaced by carburetors.
G: One distributor or magneto allowed.
H: Computers allowed for data collection purposes only.
Electric (E)
Electric is defined as propulsion via electric motors only.
A: Hybrid or ICE generators used to power electric drive motors not allowed.
C: Dual drive motors allowed in Altered class only.
Electric power shall be designated in the LTA records as a fuel class:
i.e. M/E-48 = Modified/Electric – 48 volt.


my interpretation of the production rules would be that a busa must be in the 1350 class, a zx14 would be in the 1650 class, a goldwing would be in the 2000 class and a Rocket 3 would be in the 3000 class.
You would have to talk to one of the race directors to know for sure. we are allowed to race higher displacement classes in mps and aps at a disadvantage where there is no size limit based on oem specs. whatever your motor size is in that case you race that class or higher. looks like the size limit rule has been forgotten???
it would be nice to know what the rules really are as i have a friend that may have a big change in build plans for either 1350 or 1650 production

Great speeds Steve with a bike that anyone at the corner burger joint would pawn off as stock regardless of the rules or class it fits in.

Looks like the rules would even prohibit a spacer plate under a cylinder as it states even the engine itself must have stock external appearance?
Any day on a motorcycle like this that ends just needing parts and labor is a good day.

Any modifications must be out of view, and if you use a certain piston you can eliminate 90% of a spacer. No words in the rulebook say (no use of thicker base gaskets allowed) but you can't run a 1679 in a 1650 class either.  But I did stay at the Caribou Inn  :tu:

Those Ti rods must be shorter than stock, i cant see that much lower piston fitted it would not need thick base plate.
