So I've had yet another issue with my newly purchased DT R . Was on my way to work and suddenly the engine began to struggle and would cut out. This would continue to happen unless I let it sit for a bit, but would reoccur after traveling a similar distance. Took the carb off this evening and both jets had a lot of shit in so I gave it a good clean. I'm hoping this will solve the issue. I gave the air box a clean out, the filter looks fine but the foam on the filter holder that slots into the air box has quite a lot of black on it and bits have come off it. Can I just glue some replacement filter foam on in the correct shape? Also I've had a look at an oem assembly diagram and it appears that there should be structure that sits between the holder and the filter, however mine doesn't have one. Could this also be an issue?
