Not reving past 16k and..

According to the Dyno sheets I have seen, peak power for a ZXR250 is hit just before 16,000RPM , perhaps its a good idea to change gears and ensure your cylinder head doesnt implode at 19,000 RPM (been there done that, twice)

 

Most defiantly a good point. Not really planning on revving it out anyway. It's more of a if it can't rev out and there isn't a good reason for it there's still an underlying issue that needs resolving/answering.

 

totally agree Doug, my last resposnse was tongue in cheek

 

my A model goes past 16k without protest, never know, you may have a Balius CDI lol

 

I saw a thread on another forum where someone fitted a de-restricted CDI. Just had to re-pin the the connector to switch the ignition coils around. I actually would've gone down that path had I found it earlier. Here's the links:

What do you mean by 180km speedo? Don't both the A and C models go to that?

 

hey chris, what actually goes kaput first? is it vavles bending/breaking? or? - curious

 

Valves into pistons then grinding sounds, followed by loss of power, swearing then a long walk home

It's a viscous cycle

The 180k one is off the later C model i think .
The dashes get swapped around a lot on these bikes. Hence to say the mileage reading on these bikes is almost always inaccurate. My ones reads 38 thousand on the clock.........

 

yeah i got the 180km/hr speedo also, bought it with 38k, now has almost 41k
