upright 600's
 

I have recently been looking into purchasing a mini sprint and have a few questions. First i was woundering if anyone could tell me if I got a car where the motor sits between the frame rails, would it be a big disadvantage over the offset motors in 600cc racing? Also could I use the same car with different motors for both 600cc races, as well as 1000cc races?

Re: upright 600's
 

You are correct. If you purchase an upright mini sprint you can run either a 600cc or 1000cc engine. The only point to be careful of is the diameter of the tubing. Most upright mini sprints should be legal as a 600 or 1000, however there were a few cars built several years ago that were built out of smaller diameter, lighter tubing that can only be run as a 600 car.

thank you Motorsportspr,
Also I was wondering when running with the 600's would not having the offset motor be much of a disadvantage?

Re: upright 600's
 

Make sure that you understand the difference between an upright and a modified midget or sidewinder. The modified midget has the motor offset and the driver sits with his legs straight out in front of him. The mini sprint is like a midget with the engine more centered and the drivers legs underneath (more like sitting on a bar stool).

There are very few places where the upright mini sprints and the modified midgets run together. In some cases a modified midget organization will allow an upright to run with them, however modified midgets have not been allowed to run with the uprights. The modified midget is smaller and lighter, however out west there is an organization where the two run together and the upright has won races.

Make sure you understand what is running in your area. There has been more than one case where someone has purchased a modified midget, thinking that they had an upright mini sprint - only to be disappointed that there was no where to run the modified midget locally.

If you are in the Ohio/Indiana area the upright mini sprint is probably the best choice. There are plenty of places to run as either a 600 or 1000.

so what is the difference between a modified midget with a 600, and a micro sprint with a 600? or is it just a terminology thing?

Re: upright 600's
 

[QUOTE=tomkat;81882]They are the same thing. Modified Midgets are as motorsportspr said, Offset engines with the driver sitting on the floor with the legs stretched out. They are also slightly smaller weighing aroun 700 lbs. The run a 12 sq ft wing also. They are also called Micros and sidewinders depending on the part of the country.

Upright mini sprints use basically a midget chassis capable of housing a motorcycle engine. The driver sits upright in the car with the motor directly infront. They use often the same wheels, tires, suspension components, and shocks as a full midget. They use a 16 sq ft wing.They are run with 600cc, 750cc, 1000cc, and 1200cc, though in this region you will just see 600's and 1000's/1200's. The tubing is sometimes slightly smaller than that of a midget, depending on the manufacturer. FOZ race cars, ERC, Henchcraft, and Baily are all leaders in manufacturing upright mini sprints.

Where are you from or planning on running?That would be the first question.

Re: upright 600's
 

Well I would mostly be running with the MMSA, or the AMSA. Just thought I might want a 600 to start with because I think Salem runs them every friday if I am correct, and that would be close to home.

Re: upright 600's
 

So that leads me to the next question ... I see MMSA and AMSA are both on the new Twin Cities schedule, whats the difference in rules, etc between the two ? thank you

Re: upright 600's
 

AMSA allows more open rules, can run 1200's, have to weigh 940 if your car is a 1200 or run alcohol(IDK why?) and 900 if it is a 1000cc. Pays $500 to win $50 to start. MMSA is a strictly stock series, must be 1000cc or less, have to weigh atleast 900. Pays $1000 to win, $100 to start. I think MMSA has a slightly higher membership fee. Both websites have a complete list of rules, most are generally the same besides the motor rule.

Re: upright 600's
 

i am also looking to get into racing the 600cc class i'm actually racing in ohio at 35 raceway since its only about 20 minutes from my house my question is what kind of car are they racing ie,upright or midget they are calling them minis ??????

Re: upright 600's
 

I am curious as to where all in the midwest they run both the Micro (600) and the upright Mini's WINGLESS?? I watched footage of the Tulsa Shootout where they were running non wing classes, but curious as to where all they run wingless on a regular schedule ... thanks for all the great info

Re: upright 600's
 

They run upright mini sprints with 600cc motors.

Re: upright 600's
 

As far as I know, the only place left in the tri-state area that runs uprights non wing is Bakersfield Raceway Park in Linton, IN. I could be wrong.

Re: upright 600's
 

Bakersfields runs non -wing uprights and wing and non -wing sidewinders

mini sprints are useally 250cc and under

Re: upright 600's
 

we were at lebanon (north of indy) a few years back in a tq and they ran both but not together, they must have had 5 classes wing non wing micro's and mini's

Re: upright 600's
 

I was in a motorcycle shop in bloomington a few weeks ago and they had a good deal on a mini sprint with lots of spares..Call 812-332-5262 ask for Gene or Jason!!

Re: upright 600's
 

Linton is the only place that runs non-wing upright 600's.
The MMSA and AMSA are organizations for upright winged mini sprint racing. MMSA rules say stock bore and stroke 1000cc or less only. AMSA lets you run as high as 1200cc +/-
I recently filmed the MMSA at two tracks. One was the Bartholomew County Fairgrounds in Columbus, IN and Bloomington Speedway in Bloomington, IN. My advice to anyone looking to get into mini sprints is to go to a race. Go in the pits, talk to drivers and their crews. Most drivers will answer all your questions.
I personally ran an upright 600cc @ Salem and with the MMSA and AMSA at Twin Cities. I ran an ERC chassis with a Kawasaki 636. I was told that the 636 was the BEST 600cc engine you could use. I may have heard wrong, but more than one person told me that. If you run with the MMSA there is bonus money available for the highest finishing 600cc car. And if you run a smaller track with the MMSA or AMSA...a 600cc really isnt going to be that bad, and you could do quite well.
To the best of my knowledge...MMSA pays $1000 to win ($600 for non members) and AMSA pays $500 to win. $100 to start for MMSA and $50 to start for AMSA.
If you had an upright mini sprint this year...you could run at these tracks....
Lawrenceburg
Bloomington
Columbus Fairgrounds
Brownstown
Kokomo
Gas City
Linton
Salem
Twin Cities
Moler Raceway

There may be more...but those are what I can think of off the top of my head. Mini sprints are a great way to get out on the track. I wish the drivers and the organizations the best.

Re: upright 600's
 

If you are looking for a motor, I have a 02 GSXR 600 ready to bolt in. All you will need is a muffler to go on the end of the S & S Headers. Wiring harness is complete, hook the switches up is all that needs to be done. Has two races since top end was refreshed. We switched over to 1000's for both cars and need to make room in the shop.

$550.00 complete.
