Question about 2002 Yamaha TT-R 225
Your timing may have skipped a tooth. This causes the glowing pipe. Ther are 3 positions that look like tdc. The flywheel has "I" "T" and range marks. This can be confusing. Put the "T" on the mark and you will run perfect. If not you can set it up one tooth or down one from that position. One setting makes the bike run like ****, the other one is barely noticeable more or less power. You may have to play with it a bit to get it right. If your pipe still glows after redoing your timing then your can change up your jet to a higher flow. Usually a performance filter will lean out the mix causing a red pipe. To much fuel just fouls the plug. I deleted my filter box and put a cone K&N filter. I had to jet my carbs to compensate for all the extra air flow. The bike had more power after I did this. The main jet I used was 127 or some where around there, the stock jet is 115 I think.
To much gas would never make you glow. Timing being off or being to lean will.

If your header is glowing red, you are getting way too much gas in the cylinder, and it is burning it in the pipe. You either have a misadjusted float, or your timing is off. You could be as little as a tooth off, and have a problem. I would suspect the carb flooding more so.
