I didn't have the tools or space to take care of the bike myself as it also needed a new back tire and breaks so I took it to a bike shop for repairs.

They cleaned out the carburetor and put a new gas filter on.

They also recommended a new clutch as the old one was worn down.  The bike has 19,000 miles on it so I guess that might make sense.

At this point the bike runs really well and the clutch catches the torque extremely well but I it has a lot more back fire coming out of the Dyna muffler then before.  Could this be an idle or fuel mixture problem?

Well it is my first bike when I bought it a 4K.  It just catches a lot faster now.  

The Dyna has been on there for 6 season already.

I did have the back breaks changed but that was my request since it was advised two years ago.  I had my suspicions on these guys when they had me pick up the bike.

First they told me to pick it up saturday but when I went monday the tech hadn't test drove it yet after doing the repairs.  I asked him to test drive it since that was his job.  If he survived I assumed I'd be fine.

When they turned the bike over they kept suggesting to change the engine gaskets and put a new muffler on it because it backfired a lot.  I told them I'd ride it for a while.

When I got home I cleaned the oil off and drove it around a while.  Everything runs fine except for the backfiring.  I remembered that since they changed the clutch they probably removed the Dyna muffler.

Low and behold I pit my hand near the joints and theres air blowing everywhere.

This shop is definitely not worthy of any respect or business.  They got the tire and breaks changed which was the main objective I couldn't do without a garage.  I'm going to fix the rest myself and just put a really crappy review on Yelp for them.  These guys were terrible.  And they wanted to screw me over for a new muffler and engine gaskets too.

They are called Al's Cycle Shop on Glendale Blvd. in Los Angeles.  These guys give honest mechanics a bad name.
