I've noticed a strange noise in my 700 when you lug it a gear to high. It's had to describe but sounds like something horribly wrong in the transmission when you lug it out of the bottom end. It's fine everywhere else, just a little grumpy when lugged? Do you think it may be chain slap or something??

Mine was doing the same thing and I believe what you are describing is the chain slapping the plastic chain slider on the swing arm skid plate.

Good call, hopefully that's all it is.

mine does the exact same thing.. does this mean the chain is too loose? or is this ok?

 

[Deja_Entendu700]

Probably just needs to be adjusted a little. Maybe just tighten 1/6"

Transmissions are multipliers/divisors. If you are lugging the quad, the actual power that ends up at the PTO/primary will not be correct for the load. The power will pulse in an exaggerated power-on, power-off style, and basically you are hearing the driveline lash (the play in the driveline/tranny) being jerked back/forth and the chain tensioning/relaxing (aka slapping). Find an open, area and watch it happen.

Downshift, and get into the proper powerband for the terrain/groundspeed.

Yup, does the same thing and it is brand new. Phuzz sounds like he has an expensive education. Lot's o big words, but it sounds reasonable.

Mine does it to, before and after the buildup. Its the timing chain jumpin back and forth on the "power on/power off" as described before. No biggie :thumbsup:, just dont lug around, down shift that puppy

The 700 is a strong machine, but your riding style may come into play. Short shift in the trails. I ride in the eastern smokeys, tight trails....

Think Phuz is absolutely right, i had the very same, and it went even worse after changing sprockets to 16/36 (road use) It's a simple matter of downshifting timely!!

Must admitt its a strange thing, high torque at low rpm on one side, and the need to shift down in time on the other side.....

I went 40T rear sprocket and the noise got worse...I made some spacers for the rear skidplate to move it down and that helped tremendously.

i know my stock chain roller makes lots of unwanted noise. even if i spray it with wd40 it will come back within 30 min. very annoying..
