Andrew, the 75TR6 has a sealed crankcase ventilation system. When you take
off the filler cap, you draw air instead of fumes into the carbs, and lean
out the mixture. I got mine thru emissions by doing that."Your compression
should be around 130.You definitely need a valve or ring job, but if your'e
happy with it, drive it!
