Small Company...

This is a very small company. Many of the ignition units and system kits are made to order, which do require a lead time. Often the lead time is mentioned in the product description. Being a small company does not allow us to often some of the amenities and conveniences such as a liberal return policy like high volume giants like Amazon.

2006-2008 Triumph Scrambler CDI Ignitor Unit

“Just wanted to say I’m shocked at how fast you shipped my recent order. After purchasing the coil, I went back and read the main page again. Uh oh, there was this “red font” in the middle. Like a bull, I focused on that. I thought I missed the deadline by two days late on orders. To my surprise, it showed up in just two days. (today) It was like Christmas. I bought this coil for my son. Then told him maybe September for delivery. He was good with that. You should have seen him today. I didn’t have my phone but a picture is worth a thousand words. Thank you very much! I hope this solves his issue. Either way, have a great weekend and I will do business with you again soon. – Dean Much Vancouver, Wa. Aug 3, 2021, at 10:10 AM,”
