non starter

[mojo1162]

Folks a couple of questions

ive just done a small service on my xj900f (94) oil first with new filter, the old oil smelled kinda like petrol, could this be because the bike was running rich?and the excess fuel getting in through the bores

new air filter

next was new plugs changed out with type recomended in the haynes with a 0.70 gap as recomended(the old plugs had gaps ranging from 0.25 to 0.35 and were pretty much carboned up) however the bike ran with these plugs

on trying to start her up the starter motor turns over fine and the engine is turning over but no spark and a strong smell of fuel obviously flooding, should i reduce the gap to say 0.50

or can anyone see another problem

thanks in advance

Mo my 750 runs with a 0.25 thou plug gap, are you saying that the manual says your bike should be 0.70?? that dont seem right you could drive a bus through that, go back to 0.25 and see what happens.

Cheers slice ill do that, i dont get the manual saying 0.7 though hmmmmmmm, ill let you know how it went

0.7 mm =.26 thou.

I'm assuming that it was running well before?

Might be nothing to do with it but I had a 600 suzy Bandit and the diaphragm went on the fuel tap? The petrol seeped through the tap then into the carbs finally filled up my sump with fuel....

That made the oil smell and look like petrol..

just a thought?

thanks guys, ive adjusted the gap to 0.25/26 and she fired up first time runs pretty rough though and im getting a backfire when the choke is off probably the carbs need worked on

bonnietiler -ive had the fuel pipe disconnected and run it into a tub with the petcock at the on position and nothing is coming through ill check that again in the morn

thanks again all ill keep you updated

had an eye on the petcock overnight and the next day --all ok with nothing going into the bucket, refitted the tank and marked the oil check window with a fine marker nothing getting into the sump thats with the fuel tap at the on position so the diaphram must be ok, ill take some oil from the sump and take a sniff tomorrow just to be sure there's no fuel in it, ive found a lad who's going to help out with setting up the carbs,

thanks for the advice though its always worth a looksee

All going well, had the xj out for an hrs run on tuesday just farting around and getting used to two wheels again and it felt just fine in fact it felt bloody good no backfires and a lot smoother at idle although as i said before the carbs are in need of a look at,also no smell of fuel in the sump, burnt the skin off three of my fingers on the exhausts though when i first fired up arsehol!!e, ive tried attaching a photo of skinless fingers but no joy

many thanks for all your advice
