[color=rgb(51, 51, 51)]Great product. Purchased for my Yamaha FZS 600 Fazer (1999). It had been running very roughly (low revs, inconsistent tickover, low speed running, hesitation etc) since purchase in the spring of 2014. Did all the usual stuff - new plugs, checked plug caps,coils etc (all within spec) even purchased new TPS (ouch!) but problem remained. It was during a conversation with a mechanic that I found out that regular unleaded petrol had up to 10% Ethanol in it. Apparently it goes off after a month and leaves a residue particularly in the pilot jets (hence the poor low speed running). The bike was due to go into the garage for a carb cleaning session (about 2 hours labour ~£100). Read about Profi fuel (21 5* reviews on Amazon) so decided to give it a try. Took a third of the can (90mls) to the garage and filled up with Shell Vmax (less ethanol content) and filled the tank. Pleasantly surprised - running really well after 20 miles; by 50 miles engine is as sweet as a nut! Perfect low speed running, no hesitation and constant tickover. This product also stops the water content in the fuel rusting the tank during winter storage. If you are laying up your bike for the winter its probably better to drain the tank and run the carbs dry and fill up with fresh fuel next Spring. In summary - if you are experiencing poor running give this product a try first, rather than last - you could save a great deal of cash on unnecessary parts and labour costs.[/color]
