Question about 1988 Yamaha TZR 250
After striping and re-building the carb on my yam tzr 125 2rk 1988. and put a new fuel filter on due to spluttering the bike was fine, iv done 40+ miles and ran as good as ever. i stopped in at a shop and when i got back on my bike i rode away and the bike spluttered and died. the bike has never been a smoker but now i can only get it to start for about 5 secs every now and again with the throttle wide open and in that time it gives out loads of smoke. any ideas where to start?
Not sure but it sounds like it's running too rich a mixture and/or your float levels are not adjusted properly. When you stopped the excess fuel has gone into the bore not burned which will wet your spark plug making it very difficult to start. Depending on the colour of the smoke it could also indicate that your mixture is too rich. For extra power you need more air not necessarily more fuel. I hope that helps you. Again not sure but sounds like that is your problem. :)
