Muscle Carb Cleaning Service:
We offer carb cleaning and preperation services here at the shop and can clean and prepare your carbs as well as test them on one of our bikes. The carbs are dissassembled and inspected as they come apart looking for obvious problems.

Once taken apart the carbs are run through our heated ultrasonic tank in a special solution designed for industrial cleaning. After a few hours in the tank the carbs are removed and rinsed with parts cleaner ensuring that all the passages are clear and ready for assembly. The small parts are also tanked, cleaned, and inspected prior to going back together.

We proved new jet block and choke gaskets, as well as new jet block plugs, o-rings, and misc (about $150 worth of OEM parts are used – we do not ever recomment using aftermarket carb parts). The power diaphrams and slides/diaphrams are inspected and we do have them on hand if needed but will warn you that they are expensive to replace.

Float levels are set (see the recommended settings for the do-it-yourselfers out there) and the carbs reassembled. Finally, we road test them on one of our shop bikes to do our best to ensure the carbs work normally. You will want to resync your carbs when you get them back on which is a fairly simple process.

Chrome and Stainless screws are available to be used on reassembly. We can also use our chrome exchange service at this time and install chromed carb covers (see chrome thread for current pricing). If you happen to purchase one of our Muscle Jet kits (we also sell dynojet kits) we will install those for no additional labor charge and do our best to get you a good baseline for your bike.

Carb Cleaning Service $400
Also available on exchange for a little more – please inquire (slides/diaphrams must be in good shape).

Maybe if you can clean this up and post this somewhere in the carb section?? Shows the difference between the 2 common jet brands made.

Mikuni jets are marked according to flow rate, ie: a MK150 flows 150cc of fuel per minute.

Dynojet jets are marked according to the diameter of the hole, ie: a DJ150 has a hole diameter of 1.5mm.

With this is mind …
The following chart compares Mikuni and Dynojet jet sizes based on diameter.
Jet sizes in BOLD are actual sizes, those in ITALICS would be the equivalent if they existed.
