500 Two-Stroke Tech

Has anyone tried running a 140/70-18 on the rear?

When I’m cleaning up the bike after a good run I’ve noticed there is more oil on the ends of the upper silencers as opposed to the lowers which are Grand Prix style both exiting lower right side. Is this due to the straighter line of the uppers as compared to the lowers? Pulled the plugs and all wer...

Thanks I will give that a try. Cheers.

My oil tank has split halfway down the side. Any suggestions on how to repair?.

I definitely would like a cover and not too concerned with the cost.

Looking for a battery cover for my 1985 Canadian RZ500. Cheers

What is the recommended main jet size for a stock rebuilt RZ500 with Jim Lomas pipes? Thanks

Pipes on, started up the bike for the first time this week, the sound is amazing.

Got my JL’s from Jim at Fast from the Past and he is a gem, the real deal. Absolute professional and I highly recommend him.

Do the JL uppers cross over like the stock pipes or are they a straight run back?

Ihave a full oem set.

Thanks, one less thing to stress on.

My front rotors different in thickness, one is 7.78mm and the other is 7.48mm. Is there a minimum thickness and will this be a problem as is?
