Picked the bike up Saturday afternoon from the Nitrous specialist and headed for York Raceway to test it on the Sunday.
The fitter had told me I had to purge the system before use and he had shown me the procedure.
I got ready to run, had purged the system and was all ready to make history.
The little Honda bogged off the line as is usual, cleared it's throat then rocketed down the strip.
As I hooked 6th gear, I tightened my grip on the bars and hit the button.....nothing
13.7122 seconds.
On my next run, I hit it in 5th and 6th but still nothing
13.8660 seconds.
I spoke to my engine builder during the lunch break and told him that the system didn't seem to be working and that I was going to do a static test to make sure that the arming switch was flipped the right way.
I started the bike and held the revs at 5,000 and pressed the button and........Bingo....11,500rpm
For my third run, I was paired against my engine builder and sponsor...there was no way he was going to win cos I had 10cc on him and a nitrous kit that was working allthough I couldn't feel anything exiting.
The last time we were paired, he came off worst and by the way he launched it was obvious he wanted revenge.
I spun up and he grabbed a slight lead. As I regained traction the torquey little motor soon had him overhauled which saw me the winner. I had hit the nitrous from 3rd gear upwards.
On returning to the paddock, he told me the system was working and that he was catching me at three quarter track when I just pulled away in the higher gears......14.0410 seconds
Run number 4, I only hit it in 5th and 6th and the time dropped back to 13.9031 seconds
On my 5th run I thought, fcuk the gas and recorded my fastest time of the day with a 13.6198 second pass.
The gas was obviously killing the motor, the more I gave it the more the power dropped off.
The guy from the nitrous specialist phoned me as we were making our way home wanting to know how we had got on and were we pleased. I told him what had happened and he said that the only way the system would not work under load was if the spark at the plug was not strong enough to fire the extra fuel that had been injected...basically, the extra fuel is not being burned and is causing the mixture to be very rich.
New stronger ignition system needed
