Bogging issue

Air filter is clean - i just checked the exhaust and pulled out the old solidified packing and will try to clean everything out. The comments abt 35 jet size being too small - ?  I will try anything at this point but need to have some kind of recommendation for the jetting as a starting point

Still haven't got a clear answer on what the plug looks like. wet,black ,tan,white? May need to have a few extra plugs on hand when your jetting. If your fouling a plug need to have a fresh plug to get a good reading.

Cleaned the exhaust with my 12 Gauge cleaning rod, brush and some Hoppes No 9 - worked great. I'll check the plug and put up a pic.

Mine did the same thing this spring. I pulled the carb several times and made some adjustments. Turned out my petcocks were clogged. I took them off and cleaned them out and the bike ran great.

I put new petcocks on recently - the old ones were leaking.
