thanks for the friend invite

love your pics . bikes

So, Jag, would I loose my lower end torque if I took off my intake extension for reed valve?

I am a huge believer in reed valves. I think you would have a broader range of power if you had one. But the intake extension is unnecessary with reeds because the resonance is interrupted by the valve.

As you can tell, I haven't been around here for a few months.
I just got your message from 1-23-12.
If you haven't received any recommendations from anyone else here, your plug color indicates that you either have an air leak (new one?) or the carburetor needs to be tuned up richer- adding more fuel. This can be done by lowering the clip position on the carburetor slide needle which in turn raises the needle adding more fuel in relation to the slide position. Check the spark plug color after each clip position change. If that will not enrichen the ratio enough, you will need to replace the fuel jet with a larger one. Re-jet one size at a time and test for proper coloring of the spark plug after each re-jet. A lean burn will color the spark plug white and the engine will still run like a banshee from he11. It can easily do serious damage though due to overheating the piston.
Sorry for the ridiculously late response.

i see your icon do you see mine?? and whats new??

With a reed valve you will get worse performance if you don't hole the intake skirt of the piston. Better yet is also making a boost port. You will have to rejet the carburetor. But I couldn't get the standard carb to work with the reed valve I made which is why I had to buy a Dellorto. Intake extensions only work with piston port intakes. A longer exhaust pipe should still work though.

>If I just bolted on the (Reed Valve from Rock Solid engines) to the HT 66cc, do you believe that one would notice anything? Thanks to you I've really improved torque lows and mids with longer intake. If I did extention with Reed Valve???....Wonder then what

Reed Valce hmmmm was thinking about that..... Let me know

Hey these things are a blast to ride to bad the only German thing I have one the bike is the braided fuel line...lol

I saw you port matched and did some work on your engine. Any chance I can hire you to do the same for a new engine that I will use that reed valve intake I got from australia? Any engine enhancements would definitely help the reed intake.

As for climbing pikes peak. I did get my stock engine/bike with a shifter kit up to 12,000 feet (just shy of cottonwood pass summit) before my freewheel failed. Engine was weak at that altitude but still had about 15 mph in her climbing at that altitude.
