Although you're welcome to order directly from our web site, many projects are best served if you have a dialogue with us instead. Our forte' is helping customers individually, which means taking the time to understand your particular situation: what parts you already have, what your goals are, and your budget for getting there. We then take that information and plot the most cost-effective path to help you reach your goals.

Therefore the majority of our business is done after working with the customer and creating a formal estimate. Once we've "hammered" out the details and have it down on paper and it meets your needs, that's when the project proceeds. So don't hesitate to contact us using the sales & tech form above, or feel free to call the shop and talk directly with "HAMMER Dan" Norlin.

Often a project will involve shipping parts to us for services. Usually this means a set of heads, but it can also be things like cylinders, flywheel assemblies, assembled lower ends, even full engines. In this case, the project is really kicked off when the parts hit the door. We unbox them, inspect them, identify the estimate associated with the project, and put your parts into the shop work queue. We then gather the remaining parts needed to complete the order, ordering in anything we don't have in stock. When the parts come out of the shop, we'll contact you for payment info, ship your order, and send you a tracking number. Simple as that. In general, if we have your parts here for service, we don't need any kind of payment until your order is ready to ship.

However, there are some cases where we'll ask for a deposit at the front end of the project. This is generally the case when the order involves custom parts of some sort, or a significant cost for parts that we don't normally stock. We'll let you know if we need a deposit when we work out the estimate with you.

Thanks in advance for your business with HAMMER PERFORMANCE, we sincerely appreciate it.


The most important thing to know about shipping parts to us is pack them well! Many people underestimate how fragile the fins are on heads and cylinders, and there's nothing we hate more than opening a box from a customer and finding bent or broken fins. It's best to wrap each head or cylinder in thick bubble wrap, box them individually, and then put both of those boxes into a larger box with plenty of padding around each. DO NOT SHIP US CYLINDER HEADS IN INDIVIDUAL USPS MEDIUM FLAT RATE BOXES! Yes, we know, the box is about the size of a head. But it's not nearly enough protection and there's a very low chance it'll arrive to us undamaged.

Along the same lines, if the parts are oily put them in plastic bags and seal the bag tightly! If you don't, the oil will find it's way to the cardboard box and dissolve it.

If you're sending heads, there's no need to disassemble them. Leave the valves and springs and all in place, we'll take care of it. If you have an appropriate socket, go ahead and remove any head temp sensor your heads may have. But if you don't have the right socket, just leave it in place and we'll take care of it and make sure you get it back.

Same deal with throttle bodies. If you'd like to remove the injectors and sensors and what not, that's great. But if you don't, we can deal with it.

Use the carrier of your choice; most customers choose UPS or USPS or Fed-Ex, but they all know how to find us. Ship to the address shown above. Make sure you put a note in the box to identify yourself. We deal with numerous customers every day and we have no way of knowing who shipped us parts unless you let us know with a note in the box. If you have an estimate, it's best to include a paper copy in the box; that way we know who the parts came from and exactly which estimate to work against.

Shop Turnaround Time

The turnaround time for work to go through the shop varies depending on the work being done and the time of the year. Contact us for the current lead time on the service you're considering. Our busy season is January through May, when everyone is getting their bikes ready for the riding season, so expect longer turnaround times during this period. It's really crazy in the February through April timeframe. We will not compromise the quality of our work to get things out faster, though. Also, all work is done in the order it was received.

Making Payment

As described above, most of the time if you've sent parts to us, that's enough of a deposit that we don't need further payment until your order is ready to ship. We'll contact you at that time to arrange payment. However, you're free to make full or partial payments toward your order at any time. We automatically apply any payments received to your order and you'll get full credit for them.

Any time you'd like to send a payment to us, your options are:

  • Pay Directly by Paypal. If you already have a Paypal account, the quickest and easiest way to send payment is to click on this link. Alternatively, you can log into your Paypal account and manually send payment to payments@hammerperf.com. Whichever way you do it, there will be an opportunity to add a note to us. Please enter the estimate or invoice number into that note.
  • Request a Paypal Invoice. The advantage to this method is that in general, a Paypal account is not required, you can check out as a guest. So if you don't have a Paypal account and don't wish to open one, just click here to write to us and request a Paypal invoice that you can pay with your credit card.
  • Call the Shop and Leave a Credit Card Number with HAMMER Dan.. We can, if you'd like, keep this number on file for future purchases. Please note that we do not accept credit card numbers by email, sorry, we've found this to be a common sign of credit card fraud.
  • Send us a check or money order. See our mailing address above. Keep in mind that unless it's a guaranteed check or money order, your shipment may be held up until the check clears.
Paypal is our preferred payment method because it provides protections for both the buyer and seller. To ensure those protections, please be sure the correct ship address is provided with your Paypal payment. We are required to ship to the shipping address that comes through with your Paypal payment. If the ship address that comes through with your Paypal payment is not correct, let us know ASAP and we'll refund the payment and you can resubmit with the correct address.

Likewise, when paying by credit card, please be sure your shipping address is on file with your credit card company and approved by them. We cannot accept your credit card payment unless the ship address is verified and approved by the credit card company.
