tl200

Hi everyone... Q1. Without being laughed at by all of you on this site !!!! , I have seen alot of references to "SEELEY" what is seeley, is it a Honda upgrade? can anyone give me an idea and point me in the right direction about Seeley, I hope to earn my wings one day, lol....... Q2. I am getting back on a trials bike after 23 years when back then I owned a TY250, I have just purchased a TL200 (mid 80's I think, red,white and blue) I wanted a 4 Stroke and this was the most affordable one within my budget, did I do the right thing ?... I've read mixed reactions towards TL's..... does anyone have good or bad stories about the TL200 ?
