On the basis I'm about to strip and rebuild mine I would say that's an excellent idea.
It appears a lot of TTR owners have carb issues at some time from simple tuning to jet sizing and cleaning.
For info, mine's leaking a bit of petrol and has a bad hesitate after deceleration also temperamental as to wether it likes some choke or not to run.
Well that's my six peneth worth.
Cheers Dave
PS - that's the old one not the new one which is still sweet.
