Hi, and trouble shooting question.
Hi All, Brand new to this forum. I have just bought an 86 xt 600 which I now have running. This is the third XT I've owned and I love these bikes. I rode around Australia on an '84 model back in 1994. However, I've got a tricky troubleshooting question for anyone that is interested.
The bike accelerates well up until about 3000rpm. After that, the power is very flat and won't really pull above 5000rpm. However, there is no misfire. It feels asphyxiated , short on either air or fuel. After about 15 minutes of riding the bike started performing as I expected it to. Pulled hard throughout the rev range. The previous owner reported similar symptoms.
My questions are this:
Could a weakened battery cause this type of symptom? (IE a weakened spark that reduces power until it gets charged enough to give a healthy enough spark under load. (I'm putting in a new battery tomorrow)
It feels like it's either short of fuel and air. It doesn't have the filter on the float valve but does have an inline filter. Any other culprits? The air filter looks clean and is oiled. I have a basic understanding of how the twin carbs work, but can someone point me to a link that explains how they operate. I looked on here but couldn't find a thread.
Is there a link to download the manual for this model. Again I looked. I have the Clymer manual but it is not very good at explaining the operation of the systems.
Thanks in advance for any help you can give.
