Hello all, thank you for helping in advance. I have recently started to do some work on the bike I’ve had for a few years now. It hardly ran when I picked it up but I needed a first time bike project. It’s an 07 GSXR 600. The issue: While riding around the town to see how everything is...

Just got a 2008 GSXR 600 and sometimes when I ride it everything is perfect. Then sometimes I’ll be riding and it just looses power, rpm gauge 0,s out for maybe 2-3 seconds then picks back up. I’d say 1 out of 4 times I take it out it does it. I’ve done a recent service on it. Any suggestions?
