cutting out

[t11]

Hi wonder if anybody has come across this problem before,done a couple of long runs bury st edmonds to manchester and back, the bike will loose power and the cut out, will re-start after 10mins or so but won't rev above 4,000 and then cut again, all conections checked and new plugs, wondered about fuel tap diapham or vacum pipes ........any thoughts........Gordon

i guess youve had the tank off recently.....
youve either put the vacuum pipe from the rear cylinder intake on the wrong spout on the fuel tap or the fuel lines are kinked.
whip the tank off again and have a look.

theres no other reason for it to cut out - youre not the first lol

as Benny says check the pipes under the tank first to eliminate these.

I used to have a similar problem that mine would always cut out after I had done 70 miles from a full tank of petrol. It would always fire straight back up again though.

It turned out to be a split diaphragm washer


I managed to get a repair kit from these guys http://www.nrp-carbs.co.uk/honda_fuel_t ... ir_kit.htm

I am not allowed to play with sharp objects unless my carer is with me, so I can only dream about cutting out!

Hi thanks for the reply......these two brake downs happened 2 months apart and yes the tank has been off when new plugs where fitted, its used every day and in all weathers and apart from the 2 problems starts every time very odd........on another matter I did mention fuel injection on a vtr, well its now been on test on my vtr for a year now with no problems good mpg with a home built ecu but there is more to do yet so watch this space..........Gordon

Mmmmm, that needs a post all by itself.
Did you use the Vara throttle bodies?

[AMCQ46]

+1 on that. Need to start a thread and get some pictures and details of which sensors you are using, and how you did the ecu and te map?

Throttle bodies, injectors from vara?
Fuel pump?
