Since this is my first post I just wanted to say hello. I just picked up a 1978 XS400 to build. I really want it to be a sort of desert sled tracker type bike. The bike didn't run when I got it but after a carb cleaning I got it running ok. It starts to cut out around 5,000 rpm but is fine before that. I plan on cutting mufflers off and putting universal type baffles and some sort of tips off the headers, and pod filters. I know I'm going to have to go up jet sizes, but my fuel pilot jets are both stripped so any ideas for getting them out would be greatly appreciated. I'll kept posting as my progress comes along.
