Class questions
Ok I am a moron. I have read through the Loring rule book and am having problems figuring what class my scooter falls under.
Build details.
Engine displacement : 1417cc
No power adders
Race gas
Stock frame
Rear sets
Modified seat and tank
After market windscreen
A description of what class and why would be greatly appreciated.

Your correct classification is MPS/G 1650. The record is 237.7 (sorry about that). Any external changes from dead stock (pipe, rear sets etc) puts you in modified class (M). Your displacement is above 1350 and below 1650 so you are in the 1650 class.Your fairing makes it partial streamlining (PS). Race gas allows you to run in the gas class (G). Loring allows class jumps upward so you would be better off running MPS/G 2000 with a 202 record. The A classes are for more highly modified bikes. Hope this helps. LSL

Thanks. Now it makes sense. My reading of the rules was that using race gas would put me in a /F class.
If I read the rules correctly the bike pictured in your avatar would still qual9ify for /PS since the rider can be seen from the side of the bike. Is that correct?
Shoot, I am not concerned with records just yet, still learning to ride at speed. Haven't even busted 200 yet.
It appears the different sanctioning bodies try to keep thier classes roughly aligned and the rule structure similar.

I don't know about Loring, but at Maxton you can run most race fuels in Gas class if they are in a sealed container, and inspected. Perhaps that may change for 2010, best to check with the event organizers. 
In my case, I ran MR9 at Loring, in the fuel class. The MPS/F 2000 record is me on my bike. Fortunately none of the fast guys ran in my class that weekend.

Yes my bike runs in the Partial Streamlined class but due to a rule change at Bonneville it is now an A bike. Bonneville requires gas class bikes to run Bonneville gas but Maxton/Loring has allowed sealed containers of most any gasoline as Shane stated. LSL

Randle, your modified fuel tank wouldn't happen to be under 5 liters? That would put you in Altered.
Like this bike, just buttoned up last night

The spec fuel at Bonneville is ERC fuel.
ercracingfuels.com
You can have some shipped to you if you want. Pretty expensive to have it shipped though. Unless you plan on racing in a "gas" class at Bonneville you don't need to get any. You can run your own gas at Bonnevile. It just moves you to the fuel class.
For racing at Loring like you are talking about you wouldn't need Bonneville/ERC gas. You would need to run whatever the spec fuel is at Loring. If they allow sealed contains of your own fuel then that is all you would need.

If you want to run in a gas class, you can get pretty close with an equivalent fuel (ERC A8C ~ VP C-16), then tweak the tuneup at the track. Start richer than you think of course. This is wasier for a turbo than an NA bike of course, but doable.
Loring had a VP fuel supplier last year, sold by the 5 gal pail. So you could run C-16, or U4, MRX, whatever, and be in the gas class.
Thanks for the kind words, I am counting the days until Maxton.

Actually the VP guy couldnt bring any fuels into Maine with MTBE in them. This in cludes all the MR fuels and many other fuels VPsells.
I had to pic up my fuel in Hampton Mass. on the way up because they cant sell it in CT as well.
I have heard that race fuels have now been exempt fron the law in many states now.
so check with your local VP dealer.
Dean the bike looks great!!

Thanks Jim, for the bike, and for the correct info on fuel. Sorry about the misinformation. ECTA will allow the oxy fuels, as long as it shows up in a sealed can, and you tip the gas guy.
(Jim I still haven't put the NA bike on the dyno, but will prolly take it to Maxton as a backup for the turbo.)
