It looks as though you need to put it into gear and try again Andy.

Coil and plug appear OK

Also experienced similar problem as
The coil requires a permanent live feed - . Corroison in the live feeding the coil - picked up another permanent live and the engine returned to normal. Corrosion/abrasion of the main harness is a problem with HPDI

May be worth a quick shot to get you going - best of luck

An Update on my loss of the top 1k revs issue.

The engineer has checked it with the laptop (twice) and all looks fine.
He has checked the spark strength - ok
Checked compression - ok
Fuel pressure at pump - ok

Yam are saying look at the injectors - micro filters nd so the engineer will now strip down the fuel side etc ....

This is becoming a pain the boat has been off the water for ages!

Saw you down at the Camber this morning with the cover off so assumed something was still up. Weird as I'm having a similar problem at the moment. I think I've managed (touch wood) to fix the problem - crap blocking the fuel supply.

I thought it was you but only noticed as you left the camber.

inside the vapour seperator there is a pickup gauze for hi press pump that might be worth checking

When did you last change all fuel filters.

Have had similar problems in the past, lack of power and unable to get max revs. Didn't believe it was filters until I changed them - was amazed at the difference !

Do you get "proper" WOT action for a bit then it drops 1k after X secconds / minutes use? If it's going into a "limp home" mode, it could be any one of your sensors are going in the huff or loosing contact. My only reservation about that thought is that if this is the case, I would have thought a far more spectacular drop in revs would be seen..... Unless Yam have been especially clever with their emmissions protection?

Probably worth checking every 'leccy connector under the lid - unplugging & replugging is usually enough to scrape off any cr@p on the contacts. Then reassemble with your favourite water dispersing fluid!

Most ECU faults (in cars anyway) will self clear if the problem isn't detected continuously / regularly, otherwise engine warning lights would become disco lights on the dash! Mind you, if you were out with the laptop plugged in, any fault code I would have thought would be flagged up even momentarily.


It's moments like this that old two- strokes have a certain appeal!
