Volicity Stacks do or don't

[SIDECAR77]

Hi guys just wanted some info on volicity stacks they came with the my bike 66 cb77 before I resotred it and just slaped them on and went for a quick boot and wow there was a big difference for me, should I keep them on or am I running a risk of damaging something, also made no carb adjustments.

I am running them on my cafe' bike, mainly for the retro cool factor. They do not filter the air, so shorther engine life is inevitable. If you plan on ridind a lot, get some proper air filters on it, and jet carb accordingly.

Mine have a brass fine mesh, do yours I've seen a few that have no mesh and would understand the engine destruction at some point but this mesh looks like only fine dust would get through is that enough to kill the motor, becaues I really like the way the bike runs with these.

Depends on how much riding you do, but if you're wanting this engine to last, I'd use filters.

What about K&N filters? You'd have that additional air flow, and you'd also have the 'protection' of an air filter. With the K&N's, you oil them with this red K&N oil, and that's what helps trap the dirt.

Problem with those mesh screens on your stacks is that it's not going to stop the fine particles from getting through.

Just my two cents as a non-mechanic, but long time rider.....

Yes, mine have the fine gold screen. It will not filter air properly, and will result in shorter engine life.

I have the k&ns on there now and find its a little restricted for air flow, whats alot of riding? I ride the bike for maybe 30km a week if I'm lucky, I guess I can live with the kns, I don't want to kill the motor I just finished restoration not long ago. Thanks for the info this is great site I get alot of help from posts.
