Hi All,
Newly rebuilt 1979 RD400 Daytona Special Canadian. New bore Run in finished(4 Heat cycles)
2R9 cylinders running on CDI 2.0 BTDC
2R9 Carbs with all stock settings. Filter is from Yambits ( Paper)
CDI box is from HPI Belgium. Plug : BR9ES
Running good, today I took to 140km/h but at that point the RPM was 9500. My 1977 Rd400 do not go that far for 140km/h.
And also noticed that in any point the RPM was way more than in any speed, for example 1977 would coast 70mph at the RPM of 5500, but the Daytona was RPM 6500 close to 7000
What could be the reason, is that the CDI box, should I do some setting. Please give some insight. Or is it Normal
