My VFR 750 was running pretty rough following its first outing this year, always run it on super unleaded from a branded station rather than supermarket fuel which seems to run more ethanol in their fuels. New fuel no better, so time for a carb strip which is not fun on a Vee Four
I drained the tank and changing the fuel filter then empty the float bowls no rust, very clean but a slight brown red residue in the filter
But none from the float bowls
Speaking to a colleague at work he suggested an agent that he had used on marine outboards call Sea Foam, its a US product but available here from eBay/Amazon bearing in mind a full set of repair kits would £120+ I thought 18 quid and saving 4 hours of nuckel scraping was worth a try not to mention the language involved
Snake oil or not I purchased the said product. Instructions slightly vague but enough to dose 70 litres of fuel. So not wanting to bung it all in I dose the tank 19litres with 150ml of the stuff that smells like rocket fuel then a 50 mile run. Starts OK but still no better 3000 to 5000rpm runs like a lady dog, above 5000 OK all the way upto 12000rpm. After 50 an improvement yes, rideable yes, still fluffy at low revs but no misfire. Anyway to cut a long story short I've just completed the NC500 rode 1700+ miles and by the forth dosed tankful the VFR was running perfectly, was it the SeaFoam snake oil, I think yes, would I recommend it, yes but will I do a full carb refurb this winter, yes but for less than 20 quid give it a go.
Try not to become a man of success but rather to become a man of value.
