SEND US YOUR COMER 50 ENGINES IN FOR SERVICE NOW TO BEAT THE SPRING SEASON RUSH!!

At Midwest Mini we really do know how to build Championship Winning Comer 50 Engines! From stock WKA/IKF Legal Blueprints to Full On Modified Outlaw motors we can do it all. Our fast turn around time (2-3 days) and excellent customer service is second to none. RUSH service and Air Shipping are also available for an extra charge.

Are you getting beat by other kid karts with supposedly " stock" engines? WE CAN HELP!!

If you want your Kid Kart to really fly, then you need to send us your motor for a full speed blueprinting service. We will take your motor completely apart, square the cylinder base to the bore, align and polish the crankshaft, replace the stock bearings with high performance dual bearings and the stock crankshaft seals with new low friction units, install new race spec piston rings, hand lap the engine cases, match the intake manifolds and muffler to the cylinder, properly jet the carburetor, install an advance timing flywheel key (if desired-depending on your tracks tech), new high compression spark plug and a whole bunch of other details to produce more power, more RPM's and less friction. The motor is then precision re-assembled to our exacting specs. We will also cc the combustion chamber to be sure that the volume set at the minimum legal limit. After reassembly your precision built engine is tested on our Precision Engine Dyno. This service includes break in, jetting changes and adjustments to get maximum power from your engine. You get the printed read out with all the crucial settings documented for your reference. Upon request we can also do a "Loose Rules" or "Stock Appearing" blueprint. This is a very popular setup for tracks that really don't tech the Kid Kart class but claim they go by the rule book. Engine still looks and sounds stock but will be a bit faster. With all our engine packages you will also get our special tuning and tip manual to help make your kart faster. A $50.00 extra value!

Price includes all parts and labor Turn around time: Typically just 3-5 days from receipt of your engine and it will be ready to ship back out.

This is a "no holds barred" type of engine service. It includes all of the work done above with the addition of cylinder mods with higher compression, piston mods, exhaust mods and our BIG BORE 16mm carburetor. This service will really make you motor rip but can only be used at tracks with no rules or just to cheat along with the cheaters.

If you are just starting out and not yet ready for a full engine blueprint service, we still have an excellent package for you. Includes our Engine and Chassis tuning manual which has a wealth of information that we developed over years of racing, testing and engine building. Also included are 4 high compression NGK Spark Plugs, Our Advance Timing Flywheel Key and High Flow Fuel Line. All in all, if you follow the tips in this manual and use these parts, you will be faster...for under $50.00!

LEGAL STOCK MOTORS @2.4HP OUTLAW MOTORS @2.8HP - AMAZING!! INSTANT BOLT ON HP!

The is the ultimate hop part for your Comer 50. Our MM16 racing carburetor looks just like the stock carb from the outside but the bore is a whopping 2mm larger at 16mm. Dyno tests have shown increases of 1/4hp! This is especially true in the upper RPM range where the power just keeps on pulling. Works great on stock motors as well as full mod outlaw motors and is the perfect fix for those so called "stock" motors that are continually running away from you. Great for adding that needed boost when visiting no rules tracks and then you can easily switch back to your stock carburetor for legal tracks. Includes complete carburetor ready to bolt on and 2 main jets to help you get dialed in for your weather. (not WKA/IKF Stock Legal) We also have the best price around on genuine Stock bore legal carbs blueprinted to WKA/IKF specs. Many top class champs run Midwest Mini BP Carburetors!

This handy aluminum jet holder holds and identifies all of the WKA / IKF legal jet sizes you need from 54 through 58 and is available with or without the jets. CNC machined, polished and engraved, it can be put on a keychain or hung on a wall. Have those jets ready when you need them!

We have by far the best price around on Comer 50 replacement Jets and Carburetor parts.
