87 Yamaha 350 question...

[J-man]

hi all, im new to the world of motorbikes, but i have an 87 yamaha 350 tt that doesnt have more than 10k miles on it. The previous owner rarely used it and its in great shape. Problem is that it sits for a long time and im sure the gas has turned to carmel in the carb.
I had a buddy take it apart and clean it out, however after about 15 minitues of driving it stalls out, and still feels a little rough while driving. Im thinking maybe just replace the carb entirely and start fresh - or any other ideas??? thx

ive done simple maintenace like oil, filters, new gas, etc...

Assuming you haven't been running it for months like this, I'd suggest running some carb cleaner through it and just letting it clean itself out. My first KLR had a similar issue, but a couple of days of the fuel treatment carb-cleaning stuff and all was well. If you have time and inclination, take the carb apart and clean it out (again). Check the petcock as well, and there may be gunk floating around in the tank. It's pretty simple if you've got some time, tools and a place to wash it out with a little diesel..

thx john. I actually have only run it like this for 1 tank of gas (clean gas with a can of carb cleaner), then filled it up with new gas again and still having the same issue. I guess ill just take it all apart again and let it all soak in some cleaner.

If i did want to replace/upgrade the carb - any ideas?

Check the petcock in the fuel tank,, if you have debris it will clog on the strailer, shut off,, then once settled out will run again,, The 350 tt thats a 4stroker right?? Should be a good bike for you..
