Intake Cam

I have logged plenty of data but only on the standard ECU. That was with the standard GPS and also with a home made TRE by installing a 6.8K Ohm resistor (5th Gear). It maintains the bike at 13.2 beautifully no matter what load or revs it was under and I honestly think it launches a bit harder with the TRE, so far my best 60' is 1.673 stock wheelbase.

I fitted a PC3 yesterday and will get some data from an adjusted map in the next couple of weeks. My R1 ran its best time on the 1/4 at A/F of 12.8 so I am keen to get it to that and see how the times are compared to an A/F 13.2.

My best time so far at A/F of 13.2 is a 10.224 with a top speed of 137mph. So that will be my benchmark.

I will keep you informed of my results.

If you are going high comp pistons and some "headwork" you can go with bigger cams than what you've mentioned..just depends where the budget sits.

Unfortunately I dont think the head work is in the budget or the bigger cams. I have been contemplating doing my own exhaust port cleanup but cant find any info on it other than to leave it to the pros.
Still not ruling out 1mm oversize exhaust valves with a race cut though.

I am also planning to build my own headers as a winter project along the lines of the sidewinder. I have almost finished making up a jig from the standard headers and exhaust and will also shorten the stock headers 2 inches and convert the stock exhaust to a 4-2-1 system.
