Rocket stuck in top (5th) gear and now making grinding noise... 240HP

If it has tha motec ecu I would not know the process involved in setting up the TPS . That being said if it was me I would check the low tension leads to the coils number one being the hardest to get at. (Incidently had someone call me two days ago with a similar problem and like a lot of people only check the easy coils. They were leaning towards the fuel filter and was not sure where it was or how straight you have to hold your faceto get it out). Anyway after talking to him he then realized it would be easier to check out the leads on the front coil first before messing with the fuel filter. About 1/2 hour later i received a email say bingo front coil did it. That being said I would check ALL coils first then vacuum lines and caps the chang the TPS and do a full ISCV reset. If there is any worn spotsinthe TPS it can muss stuff up. Even the F to L switch over since this point is a combination of rpm and throttle position. Imagine your throttle position point bouncing around sending hair brain signals to the ECU and the ECU saying WHAT ???????
Again I am not sure how the MOTEC is programed but I am sure it's technical. Have a look at the high tension coil leads whil your under there for any cracks and such maybe at night in the dark would show a weird spark jump just in case.

Also if Nev pops in and gives advice I would listen to him before you listen to me

Outstanding write up and advice as usual @warp9.9 my man! Love it!

Very interesting about this low tension side business.

As for fuel filter, I'm fairly certain my setup is factory still and is still inside the fuel tank. (You do have to hold your facial expression in a strange manner to make it happen hahaha ) but it's really a fairly straight forward job. I have been led to believe that inside the fuel filter housing that there is a corse and a fine filter element. The latter is, of course, the most likely culprit for low fuel flow which leads to a low fuel pressure issue, this can make ya bike lean out under load, and can sometimes even kill the pump.

I'll check this low tension stuff today and see what transpires. Going to check out and possibly rewire the fuel pump/level wiring today (as it's short and has been tugged on once or twice). Then I shall turn off data logging on the motec to free up some memory as I had a 30 min convo with a mate in cairns early this morning that's a bit of a wiz kid, and he has seen similar problems due to this.

Looking forward to smoothing it out because she halls some serious ass when it pulls right through clean.

Cheers again @warp9.9 you truely are a legend

If you have the parts about 24 hours start to finish would be my guess. To me it sounds like you have more then a detent spring problem. Sounds like fourth and fifth dogs are in mess or partially engaged. What year Rocket is it?

@3Katz I'm looking forward to this salt thing, on paper looks like the bike should be capable of the world record, and I'll be going with a friend, who's a bike mechanic, and currently holds 5-6 world records in different categories himself. We have every chance of making this work, so wish me luck!

Hope to see you over there, if ya find my bike, the black ice racing crew, and our camp, don't be a stranger! Come over for a beer or 30, shoot the breeze with us!

Cheers

It will be a bloody spectacle record or no record to see this thing in full flight but I'll be wishing you luck for sure. Cheers mate you'll definitely see us there, looking forward to it!

REMEMBER the salt will ruin your bike so spray it with a protectant we use LEMON PLEDGE spray it on and dont wipe off the excess let it sit and keep using it to remove the salt when your there it keeps the salt from sticking so spray everything especially under the bike
