I recently bought the IRK kit off ebay that everyone has to try and freshin up my 70cc bike. I installed it on my chinese crf 70. The bike ran flawlessly before i put this kit on. I installed the components and ran it off my stock harness into my aftermarket rev box (didnt use the red one that came with it) The bike backfired while trying to start it and would not start. I adjusted the timing componnets to be i nthe middle and the clearances to be a paper thicknesses. So I disconnect the old harness and tryed installing the red box you get with the kit. Still no luck. Now the bike doesnt even back fire. It has plenty of spark. I tryed jumping it. Checking if its flodded. Cleaning the plug, heating the plug, adjusting the timing. checking all the wiring connections etc. Im starting to think this kit was the ****tiest idea ever. Everything is hooked up just like the picture and its worse wit the ****ty red rev box. I need to get this thing running. Help. I think the timings off still or somthing? Did i miss a small detail.
