cheese monkey Posted November 20, 2019 Posted November 20, 2019 Getting occasional carb spitting on idle and severely bad on small throttle openings. Just done the valves, they were tightish and are now on the loose side. It was present before but nowhere near as bad. Not sure what to do with it. I would hazard a guess the timing is off, but obviously I haven’t touched it. I suspect getting the tight valves may have been masking it? I will try a B12 cdi too, have been using the standard GSX750 but as it was running on load didn’t think it needed swapping. Also still got a fucking awful oil leak. Anyone make up lines for standard B12 coolers? Quote
dupersunc Posted November 20, 2019 Posted November 20, 2019 Spitting normally means the engine is running lean. Check the carbs are balanced too. Unlikely to be the timing. Quote
cheese monkey Posted November 20, 2019 Author Posted November 20, 2019 Could a vacuum leak cause it? There’s a serious bodge of pipes on it at the minute. I’ll rip it all out and see if I can find some proper caps Quote
cheese monkey Posted November 20, 2019 Author Posted November 20, 2019 Fucking right it was vacuum leak one of the bodged pipes was totally open at one end 2 Quote
cheese monkey Posted November 20, 2019 Author Posted November 20, 2019 Well fuck knows where they have gone. 13274-84000 I think? Quote
cheese monkey Posted November 20, 2019 Author Posted November 20, 2019 How about the oil leak though? Pretty sure the union between the solid pipe and flex is gone. Anyone know anyone that makes them? Ive had second hand ones before and they're usually knackered. Can get a new cooler kit but £££ Quote

Got a Pirtek just down the road as it happens. Thought they only did commercial jobs but I will give them a call if I need to. I changed the plug well gaskets (thanks to more top advice on here) as it previously looked like it was leaking from around no3 ex. Fingers crossed that it was just left over oil mess heating up and running off last night. I pressure washed the front end last night which got rid of the worst of it and currently there’s no drips. Just got new caps on the carbs from Fowlers. Idles better now, spitting gone! The previous owner had left the bodge of hoses on from when he balanced them and I admit to ignoring them. Definitely running a bit warm so still probably a bit lean but I’m not too concerned, at least it’s significantly less likely to burn down now and I fucking hate messing about with carbs. It’s not going to be overly lean as it’s still on stock airbox but does have a can on I know this is all fairly pedestrian for this forum but always good advice and always good to write it down for others!

cheese monkey Posted November 21, 2019 Author Posted November 21, 2019 Just got to get a longer bolt for rear engine mount so I can fit crash bars and that’s this series of bodging done. I know crash bars are shit but I’m going elefantentreffen for 1st time so figure it might be wise. Quote
Foz Posted December 4, 2019 Posted December 4, 2019 Carb sneezing is usually a sign of being lean. Quite a lot of bandit 12’s do it , usually a half turn out on the mixture screws sorts it Quote

Quite a lot of bandit 12’s do it , usually a half turn out on the mixture screws sorts it Thanks Foz, you’re right but I’ve sorted it. Major vacuum leak. Turns out with the oil leak I think I’ve fixed the top end one and caused another one by pressure washing the crap off the front of the engine. Doh. 99% sure the starter cover gasket has gone, must have gotten a little close with the jet. Quote
Swiss Toni Posted December 6, 2019 Posted December 6, 2019 Stick a picture of your Pirtek hoses up. Interested to see how 'Industrial' they look! Quote
