I have a 98 ATK 605 that I have had since 2003. It has a Big Gun exhaust with the quiet core that works great.
lately the bike will not start when cold. I usually need a tow to get it going. After that it starts great. It will start every time with starting fluid sprayed on the filter.
I adjusted the valves (they were very tight) and took apart the Delorto 40 PHM. I run a 65 pilot and 188 main as recommended by Keith at ADB about 3 years ago. I also went through the choke as this has given me problems in the past.
Anyway according to the manual there are 2 timing marks on the upper timing pulley, I have a groove and a white mark next to it. Am I understanding correctly that the grooves on the 2 pulleys should line up exactly? (Both currently line up.)
