Well I got a deal on a TTR. The plan is to make it street legal in GA and do some dualsporting. It does have an issue that I am not sure where to start. At about 3/4 revs, US models don't have a tach so I am guess, it seems to cut out and loose power. Any suggestions where to start looking. I am going to start with a good carb cleaning but the PO claims he already did this. Then I am going to check and adjust valves.
Thanks for all the info so far. Look forward to becoming a participating member from the US.
