overheating issues

[71_400TRX]

i recently made the switch to Mobil 1 10W40 4 stroke synthetic racing oil, and Rotella 80w-90 gear oil, im wondering if this is a bad idea cuz when i went riding today it seemed like it was over heating very fast and acted rather boggy. any help before this week would help, i have a race next weekend and id like to get this fixed. thanks

double check and make sure you didnt overfill it with oil. I accidentally did that once and it seemed boggy. Just a thought.

You put 80w gear oil in the tranny?

ya i thought i heard of other ppl using 80W. bad idea? what shoud i use?

I use 80w bel-ray gear saver. no problems

80W motorcycle gear lubricate is equal to 10W30/10W40 motor oil in weight. If you used automotive 80W gear oil that is way to thick.

I only use Honda GN4 10w40, I have never , ever had a problem.

I use Rotella 15w-40 and have no trouble with it.

I use Golden Spectro 80W gear saver. Any of the above mentioned are fine also.
