Working on a 1970 TC120; airbox questions
Posted: Sun Feb 01, 2015 10:33 pm
Hi all. I picked up a TC120 that hadn't run since probably 1975. Pretty cool vintage bike with all the parts still on board. Cleaned everything and changed the cables and the replaced the original tires. The airbox boot was unsalvageable, so I put on a K&N I had lying around and tried to start it up. Managed to get it going after a while, but it bogged on any acceleration. I started taping off the K&N to reduce airflow, and I have the bike running pretty good now. Thing is, I probably have the entire air filter taped off except a small square about 5mm on a side. That's not much airflow, but it is the only way to make the bike run properly.
So questions: Does this sound right, or do I have some massive air leak into the cylinder somewhere? I haven't started looking for a leak, but I will if this sounds likely. Or am I badly deficient in fuel flow?
And does anyone have a suggestion for sourcing a new air cleaner boot?
All suggestions welcome, and thanks!
