just bought 2005 GTR50, the owner told me that he has the performance kit on it, so far i don´t know what it is, he said it got the bigger caburator, also he told me to dig the brass in the mufler tail pipe out, i did that, but i think the caburator needs to be adjust, the engine flood easy, i have to take the spark plug out and let the fuel evaporate out the engine to get it running again, also the engine stall easy, sometimes the idle go very high, like 3000 rpm, can someone show me how to adjust the caburator, i live in winnipeg manitoba, i thought someone here is from winnipeg, can´t remember which post, thanks..my e-mail address is strangerbyngight@hotmail.com
