Re: micron pipes?

The bike has individual uni filters with a boost bottle crossover between the carbs. Is the Y pipe supposed to improve the intake flow more than the individual filters? My previous 2 stroke tuning experience is on the older air cooled, piston ported engines. The water cooled, reed valve, YPVS is a n...

Re: micron pipes?

Great info. The P.O. said that the carbs had a jet kit and new reeds (but he also said spec II's), so ill open them up and get the jet sizes and report back. In his defense, I think he owned it for a year or so and only maintained it, no mods. The carbs are 26mm mikunis. I do like the idea of Toomey...

Re: micron pipes?

Those look pretty close, and they must be black chrome with the pitting I see. Thanks for the help. After searching the forum and the web I am leaning towards toomy's for the street. Any input is welcome.

Re: micron pipes?

The end cans are stamped micron, the PO called them spec 2's (my confusion). They are I little heavy, but built well. Power down low is good, a bad stumble around 4-5k, and then it takes off to redline. I haven't played with the jetting or the carbs (no airbox, uni foam filters). I have a bunch of p...

Re: micron pipes?

not a good pic- the end cans are aluminum, and the chambers are kind of ceramic coated gloss black.

Re: micron pipes?

Thanks, they are micron. Any idea which are the best for the street? I thought lomas were supposed to be peaky. I run Dencos on my H1/ H2, but I have not seen them for RZ's. I would think about putting on stock pipes if I could find a decent set.

Regards,
Anthony

micron pipes?

Hi all. The forum helped me out tremendously on my search for stock handlebars I am going to ask another question. I have an 84 rz350 (Kenny Roberts) with micron pipes (spec II?). Both exhausts exit on the right side of the bike. I like the power of them, but I would like them to exit on the left an...
