+1 for new Golden Spectro 6 for 6 speed transmission. Really makes 5th gear whine disappear

 

I just changed mine with Walmart full syn 75W140...had shockproof before and 25W50 before that...still have yet to see any different at all...shift, sounds clunks the same....

 

Use SYN3 in all three holes, both bikes.

 

It's a gear box so use a gear lube. I personally use Mobil 1 75-90. You can get it at any auto parts store. Easy to find.

 

Mobil 1 75W140 cause it is a gearbox, need gear oil not motor oil.

 

Before I started taking care of my scoot myself,the shop put in Syn 3 in all three holes.
My last change I put in M1 75-90 inplace of S3. Noticed numerous metal hairs on the magnetic drain plug at the time of the change over.
Just changed it again after 5k again with M1 75-90.No metal hairs. It started shifting way better after the first round of M1.

 

I've tried several including that Pepto Bismol looking stuff (Redline) and am back to Mobil 1 gear lube. I can see no difference with any of them.

 

ant good synthetic GEARLUBE look at availability hate to be out on the raod have a problem and have to mix it cause ya cant find what ya got in it.

 

so then the HD screaming eagle oil aint no good ????

 

+1 Amsoil 75-140 severe gear in mine.
