Issues after valve adjustment on my TBR7

757nick · 12-09-2021, 09:03 AM

I did a valve adjustment last night and everything seem to be fine then on my way to work the bike started to stutter as I went over 45. I’m not sure what the issue is but any help would be appreciated! Thank you!!

Check your valve adjustment. It's not uncommon when tightening the locking nut for the adjustment to get tighter. Always re-check after tightening the nut.

Yes, recheck the valves. Also make sure you didn't accidently put the choke on half choke. I've done that.

When i adjust the valves, i use one feeler higher and lock down on that because it will compress as you tighten. This usually allows the correct feeler to slide in with slight drag.

Might be something completely unrelated to your adjustment. Might check spark plug and kinked fuel line.

Usually the lash is tightest (on most aluminum head ohv motors) when they're cold. The symptoms are they get harder to start. This doesnt sound like your issue.

I probably did. I turned around and went home and got my roommate to take me to work. I never checked. When I get home I’ll check but that’s probably the issue

It happens to the best of us. Glad it was something simple.
I might be psycho.
