Since my bike is approaching 2k on it I'm thinking on switching to semi synthetic Bel-Ray oil.
It's around 8 bucks a quart.Anybody here use Bel-Ray or have any opinions on it?
"They" say it's really good for the transmission.

 

I was using a blend, but recently went to full synthetic...it made a huge difference. The bike shifts better, runs smoother, and actually has more power. I use the castrol 5W superbike synthetic...can't remember the name exactly....r5 or something?

 

And you don't have any clutch slipping problems with full synthetic?

 

None at all, everything is actually woring much better on mybike, some of the guys said they had some prob. in a past thread, but none had a zzr. My brother put it in his 06 gsxr the same time I did mine and he really like his as well.

 

I used it for the first 4 oil changes, and now I'm on Amsoil 20W-50 full synthetic. $10.00 a quart and worth every penny. Oh and just like the Muzzy pipe, Amsoil is also the best.

 

It is quality from what I hear...but the best....I dont know, havent used it, but castrol works well for me.

 

20W50??? Why so heavy.... aren't our bikes supposed to run 5w30???Does it give you any advantages???

 

His might be different because it is a dual-sport.

 

Repsol full synthetic

 

Right..... I just looked at this sig..... yeah VTwins take 20W50.... and I also checked the ZZR600 manual and it recomends 20w50 for really hot tems
