Spitting

undertulsa · 08-28-2009, 10:27 AM

200-GY, 2007 - when I get the bike up to 50-55 it sputters and kinda coughs like something is missing?

I'm no expert.

Since you can likely move through the gears without any other trouble, I'd start by looking at the electrical side. Have you installed a genuine NGK lately? If so, maybe the plug wire is bad (you can also change that for an NGK and lose about 1000 ohms of resistance).

Replaced the spark plug per our earlier discussion. havent done the wire will consider next. What is the electrical slide?

My HSUN will not rev past 7500 without the same symptoms. Ditto my buddy's identical bike. I thought it was the CDI's rev limiter kicking in. Our bikes do the same thing at about 55.

Both have aftermarket rev limiters. The origianls went Tango Uniform.

FastDoc, When they went Tango Uniform, did you say Whiskey Tango Foxtrot?

Did the aftermarket rev limiters solve the problem, or does the bike still sputter?

undertulsa, I'm saying electrical side, not slide, meaning not the fuel or air side of the equation. Make sense?

undertulsa · 08-28-2009, 12:01 PM

electrical side ok duh moment.

Can you get a spark wire at any bike shop or is this a paypal situation?

undertulsa · 08-28-2009, 12:03 PM

Is that when at full throttle? Does it smooth out if you ease the throttle a bit from full throttle? Any changes to the bike like exhaust, carb, jets?

urban dictionary : tango uniform adj â€“ slang: military phonetic alphabet for letters â€˜tâ€™ and â€˜uâ€™, used as euphemistic abbreviation for â€˜tits upâ€™.

Or he could have meant a "Tango" "Uniform" ?????

undertulsa · 08-28-2009, 12:48 PM

oH TITS UP, HA

no changes to throttle or adjust carb jet.

850mi, yes it smooths out when i back off.

Yup. 8)

I was lucky to get home when they took their respective dumps.

The 'cutoff' was the same with the original and aftermarket CDI's.

FastDoc · 08-28-2009, 12:58 PM

Based on my experience, I'd bet it's (Chinese standard) normal. Maybe one of us has tried one of the 'race' CDI's which supposedly remove the rev limiter, if there is such a thing.

I think, for me at least, 55 MPH and 7,500 RPM are reasonable operating limitations for a little 200 cc OHV engine. As long as it continues to run well I'll quit while I'm ahead.

Weldangrind · 08-28-2009, 02:05 PM

Has anybody tried an NGK plug wire?

liverchip · 08-28-2009, 02:29 PM

I replaced the plug cap with an NGK due to cracking on my old one, but not the whole wire. No notable change in performance.
