I inherited my father's 21 fxbbs this April (making the bike almost 4 years old). He purchased it new and between when he got it till now there's only about 200 miles on it. He kept it in a covered space equivalent to a car port, and I was able to ride it to my house about 2 hours away and now it's garage kept......I plan on using mobil 1 v twin for oil, and bel ray in the tranny and primary when I do the fluid swaps.

Should I go ahead and just send it till I hit the 1k? Or go ahead and swap all the fluids?

 

I'd change all the fluids now, the bike and fluids are almost 4 years old

 

Another vote for now.

 

Any reason to not use mobil 1 and bel ray as opposed to the syn 3?.......I realize fluids are fluids, but figured it wouldn't hurt to ask.

 

I NEVER use HD'd fluids.

 

Ton of oil and ton of opinion.

Id just change the oil now and be done with it. For break in, many change it 500. Some used to even do 50. It's all black arts.

 

Alright I'll go ahead and do what I was initially planning to do and swap em. Flush the brake lines when I get around to it this fall.

 

If it has abs or hydraulic clutch sooner the better . Not sure if that bike has either.

 

Change the oil. Manufacturers say at least once a year, oil companies say no longer than two years even if new due to moisture absorption from atmosphere.

 

I'd go with Amsoil for the motor.
