I recently re-torqued the head of my '70 TR6R as I was told I should do so after 150 miles. Granted I did go a little longer than that (~200ish), but I got it done. I was also told I should do a valve adjustment as they would be too tight after the head was torqued down. I set the intake at .002'' and exhaust at .004''. I assume this is correct. What I'd like to know is if there is a special type of feeler gauge you guys are using to get in there.. I did the adjustment to the best of my ability and I have the feeling something isn't right. I immediately noticed a lot more 'chatter', or 'ticking' when I first started the engine. I thought I was being paranoid so I took it for a short spin and noticed a little smoke. Before any of this I never noticed any smoke. What could I have done wrong? Where can I get a feeler gauge that would make this easier and more accurate? Should I stop riding the bike completely? The smoke is very light, but it is noticeable.. Any help would be very much appreciated. Thanks.
