Apologies if this has been covered before. Wondered if anybody can help?
Ive finally run in my PX125 MY Disc 2003 having had a DR177 fitted (has a SIP Road 2.0 exhaust, 24mm carb, drilled air filter).
Performance wise i was not expecting a thrill machine from this setup but im getting loads of torque, no problem with head wind and it screams along at 62mph GPS verified (speedo is way out, stating 110kmh when it isnt).
When i say scream, its not noisy, but im clearly at the end of my gearing, as if its thrashing the balls of it.
I have heard much about the teeth of the clutch increasing gearing. I know the MY was fitted with a cosa clutch as standard, but does anybody know if it was a 20 or 21 tooth as standard. If its a 20 tooth, what can i expect from a 21 tooth, meaning will i be able to push maybe 5 mph more on my top end which would place me in the same position as my old p200 which would sit about 65/67 mph all day long.
Im happy with the upgrade but would like to sit at 60mph without thinking im trashing my 4th gear's peak. Cheers all malc
