You have the right pipes Crawford pipes make good usable power.
Rick was a friend miss him yelling at me for touching his bikes. I have done a few RG's in my past. I like them over RZ's way simpler. I am a RD guy so Yamaha is my staple. But Dam those thing go fast.....

Will be watching your progress.

The RG has been on my list since 85.  :thumbs:
I almost had an RG500 myself, but the deal fell through when the guy saw the market going up.
So I bought my RZV500R, and doubt I'll ever have the spare cash after building that, for a RG now   :sad:
Genuine engine parts are slowly drying up, but there are enough people out there who still have bits for them.....at a price.
I found several of my bikes here on this Japanese site....as well as all the spares I have for my home market bikes.

After some diagnosis I have found that my powervalve servo is not working. It passes half of the bench tests but fails in the bike. Does anyone know if the can be repaired? Who does work on them? Anyone have a spare they will part with? Thanks -Ian

Zeel ignition.
Fully programable, and cheaper than finding the right used box.

I got my Chinese bodywork, it looks killer imo. The paint is very nicely done!

I also stripped the motor and sent the cranks and top end to Ed Toomey for a rebuild. This bike had been seriously abused. I had to weld this cylinder up where someone pryed on it and created a huge air leak!

Just gorgeous.  :like:
I post waayyy too much

Initially you said the bike was running good.
Did the air leak from the cylinder base cause a melted piston ?

Lucky for me it did not blow up, it would not take the gas, it would buck and cough like it was running out of fuel. Strange symptoms cause it would run ok sometimes. But I did a leakdown on it and found this leak and another on cylinder 2. This bike did run and seemed fine bit as usual it was hiding gremlins. Gonna be super awesome when it's right

The body work does look great!  Where did you buy it from, I'm wondering if they have other models as well.

Fairingmaster they're outta China, did a fantastic job on tge paint 10 outta 10. the fit is probably a 8 outta 10, good but a little fiddling required. I expected that part but the paint blew me away

Considering where you got it from are you surprised it has had a hard life?

I would not have said the PO would have done any hack work though. Wrung its neck? Oh yes. Definitely.

Looking forward to seeing it next May.
