Hello all and fellow bikers. 2 weekends ago, I bought my first motorcycle (07 Rebel 250 36000 miles). Then that Sunday, I drove the bike from my place in Lincolnton Georgia to Harlem and the bike ran fine, then on my way back from Harlem, maybe 3 or 4 miles from home, I started losing power at 4th gear. I backed off the power little bit and I had power again but I couldn't speed up and that would happen with all the gears if you gave it full power, the engine will lose power. It could be several things like water mixed with the fuel, clogged fuel filter, bad plugs, or bad coils and the next problem is a small clicking noise on the left side of the engine when it's running and if I'm in 4th gear going up a hill, that clicking becomes louder and I only hear it's on the left side not the right side. when I started taking the bike apart a little bit I saw that someone had really done a botched job on this bike possibly just to get it sold. Paid $1,000 for it. I hope this is enough information for you to possibly diagnose the problem.
