are you saying you can wheelie at 70mph? ive heard of this on the xl but theres no bloody way i can see mine doing that.

my gearing is 15-41. works well with speed limits and the rev range with gear changes usually when the next speed limit is reached - if that makes sense.

15/43 is pretty tall. It shouldn't be buzzy at 60-70mph unless it just sounds buzzier than you're used to.

I did not know wheelies were a problem. I guess I've needed help since, forever.

The bike won't rev out till over 100 in 5th gear with the stock gearing. If it won't go over 70 something is wrong. Mine revs out at 85 with 13/45 on it

By revving out you must mean the rev limiter comes into play. This is built into the CDI unit and protects your valvetrain from the consequences of valve float (bent valves ) Valve float is what happens when the valve springs can't keep up. The engine is rotating so fast that the valve springs don't close the valves fast enough.

Man, I'd like to build a 600 RFVC to have the kind of power to take me up to 100 effortlessly and with minimal vibration. I get quite a bit of vibes at 65-70, probably because of out-of-spec rockers and cam, that's the only thing I have wrong with my engine right now.

Mine will do 75 pretty easily. The problem is that I get that knock at that speed. And when idling. Y'all have told me that this is the timing chain slapping around and normal. Being conservative with machines to make them last longer (read: cheap) I'm looking to go with a 15 / something combo that will get the rpm's down to where the bike purrs along. Currently, thats at 60 to 65 with the stock tires.

My 2 cents.

I tend to thrash mine, it's a toy rather than my daily transport so I have no qualms about running 4-6k which is where the power is. My bike hits about 95 with the stock gearing but it's nowhere near the rev limiter, it's just out of grunt. The bike handles poorly above 75 but it's the chassis that limits it not the power.

15/40 is the best for commuting.

Is that 95kph? I'm talking mph. IF I was going down I-70 out of the mountains, with a tail wind, I MIGHT get to 95. At altitude here, we lose power. Got 14t counter sprocket. I haven't checked the rear sprocket, but it is not large. Gonna have to change them for more speed. And more cowbell.

Yup, that's what I was thinking.

What does the vast knowledge base here think could be the problem??
Bad contacts on switch?
Bad switch?
Thanks as always for the help.Would hate to think I would be out on the trails,turn off the bike and not be able to turn her back on.

Same thing happened to mine. It's the switch, get a new/used one. Check Fleabay or these guys. http://www.tricountymotorcycles.com/ they were close to me in CA.

You must have taken that picture when it was new.

[Janosh]

Sorry, where am I? Oh yeah, 13-15 and 41-44 lets see....big drive gear , smallwheel gear. Try 15/41. I think thats what my 83 had when it would do 100

Thanks. I cleaned it but it still wants to act up occasionally.
I'm ordering a new contact base assembly from Honda of Troy. Only in Ohio so shouldn't take tooo long. Just trying to button things up for my vacation in 2 weeks to Moosehead Lake in Northern Maine.
New tires coming this week. I'm trying IRC GP-1s. Have to see how they do. My knobbies are just about gone now
