- HRC delimiter: not required - do the wiresplice
- Zeeltronic: not required* - the standard PGM-III is good for in excess of 70hp
- High compression: DON'T DO IT! - the NSR doesn't need, or like it!
Stock MC21 is 7.4:1. The above TT-F3 motor ran the HRC spec 7.9:1 and pump unleaded. No need to go wild with compression ratios on the NSR. It will just hit an RPM brick wall and detonate. You'll note there is no need to rev the knackers off of them either. Even the TT-F3 makes peak power below 12,000rpm.
Check the new crank is true. They're never as round as you would hope/expect, even from Honda. We true ours beyond HRC spec, and you can feel the difference through the footrests and less harsh over-rev. The motor will be significantly smoother with a well built crank!
*Programmable ignitions are more likely to be useful with 300 conversions, where they seem to respond more to tweaking the RC Valve and ignition timing.
