2021 CSC TT250 fix for sputtering under acceration above 4k

Rickeyradfo · 02-05-2021, 07:07 PM

Hi I am new owner of 2021 CSC TT250 & new to forum
While putting break- in miles noted bikes would run fine below 5k rpm..bike would start sputtering under acceration above 5500 rpm. Returned home & noted fuel line from tank to carb was long & routed from tank was route down then up over harness down to carb. I disconnect fuel line & cut 3 inches from line. Repositioned line with a direct path to carb. Now bike does not stutter & pulls up to 8k with no problem. Bike only has 100 miles on it & i saw this fix in another forum.apologies if this should have been posted in another area.
Good luck & love this forum's feedback

I had the identical problem and identical fix on my 2020.

I cleared up all problems once I rejetted.
