Frame was cut in the rear and tightened up. suspension swap from a hyper. Custom exhaust. Overall a super fun...

    Compression? How low is too low...

    Hey guys. My CX 500 is only putting out 70psi / head right now. The bike feels pretty slow out of starts and has no real top end. Makes plenty of noise but not get up and go. After extensively tuning and cleaning carbs and ruling out other options I figured this was it. (Checked compression...

    JETTING? Is my brain thinking correcty?

    Alright. So I just moved from living at sea level to living at 7500' above sea level. Whenever I do a bike, I usually open the exhaust, and put pods on the bike. I did this back at sea level and usually bumped 3 main sizes and one pilot size and the bike would run great. Now that I am way up...

    XS 750 Valve "Hammering" Noise - Video!

    So I took the heads off the bike to check the pistons, and when I re-assembled the engine something changed within the intake valves. When the engine is cranked, the intake valves make a very loud metal-on-metal hammering sound. When i took the cam cover off the engine, I noticed that the...

    '80 Yamaha XS 400 Cafe / Fighter

    So here is my second solo project. I bought this ’80 Yamaha XS 400sg as a bobber project. Had a handful of parts but still a good amount was missing. Along with the missing parts, it had a homemade wiring harness that was barely half way complete. I was able to pick it up for $300 so I looked...

    WANTED: Exhaust Sound! Low Rumble!

    So I have an 82 GS 450, and an 80 XS 400 and they both have an awesome low rumble to them when they run. I also have an 83 GPZ 750, but (IMO) it sounds like crap. I really like the separate "glug - glug - glug - glug!" of an engine (from the GS and XS) rather than the constant "merrrrrrr!" that...

    81 Virago 750, Sparks SOMETIMES

    Working on rebuilding my buddies Virago 750 last night, and rebuilt the wiring harness. When we tested for spark, #1 coil HAD spark, #2 didnt. Thinking it was a bad coil, we switched the coils just to see, and #2 had spark and #1 didnt. So the GREY wire coming out if the CDI was putting out...

    '82 GS 650L ... Hates the throttle

    So the '82 GS 650 we have been working on hates getting throttle. The carbs have been cleaned 1000 times so there is no blockage anywhere. The only ting we changed was the float heights and reset them to the factory setting, however, after that we went from a running bike, to a backfiring...

    Rectifier, Voltage Regulator, CDI(igniter)...what else?!?!?

    So I have an XS 400 and it has a homemade wiring harness. All it has is the Rectifier, Voltage Regulator, CDI(igniter) and the bike runs great. My friend has an 81 Virago with a rats nest of a wiring job and I was just wondering if we stripped it bar bones if my technique of just having the...
