I recently ordered a tecnigas next r for my bike,I put it on and went for 1 mile of test run,felt like losing power at WOT ,.I knew I had to upjet anyway,came home and upjet my main to #90 from #72.I put everything back together and as I start the scoot ,It won't start .checked and replace sparkplug,siphoned gas replace with fresh one,cleaned carb and still would start...Now I'm thinking did I damage the piston in that one mile of test run?(mostly half throttle).Any advise would be appreciated.......
