3) To adjust the idle RPM you must have a warm & running engine. To reduce the RPM turn the screw clock wise. To increase the RPM turn the screw anti-clock wise. Be gentle with your movements and don`t just turn the screw heavily in one shot.
Change the battery. Or recharge it. Alternatively, put the bike into second gear, hold the clutch in, push it until it`s at a decent speed, release the clutch it will start. Take out the air filter, if it`s dirty replace it.

Yamaha YZF-R15 0-60 mph in 10.00 seconds.
A non-cranking condition could be due to a dead battery, blown starter-motor fuse, faulty starter-motor relay, a safety override (like the kickstand being down while the bike is in gear), or perhaps even something as basic as the kill switch being in the off position.
Yes you can purchase the R15 V3 as it is beginner friendly bike. But remember to ride it slow with protective gear and a good frame slider.
Yamaha R15 Version 3.0 carries the most powerful of all 150cc engines available internationally. The 155.1cc, single cylinder, liquid cooled and fuel injected motor is good for 19.3 HP at 10,000 rpm and 14.7 Nm at 8,500 rpm.

Bad Battery Symptoms

If the cranking of the engine is sluggish, like your vehicle is harder to start on cold mornings, it starts inconsistently, or there`s no sound and interior lights when you try to start, suspect a failing battery, a loose or corroded connection or electrical draw.

If a motorcycle won`t start after falling over, the biggest reason may be due to fuel delivery issues such as too much fuel leaking into the engine cylinders. The motorcycle may also have an internal switch that has malfunctioned or have a disconnection in the electronics because of the fall.

I have a 1996 yamaha wave venture 1100….ran greatsat for 2 yrs..started but only ran for spray into carbs….drained fuel started and ran good. Started about month later and would only run as long as primed with starter fluids…checked fuel filter(ok)…fuel flow to fuel pump ok…output of fuel pump appears ok….but engine will only run as long as starter fluid/gas is sprayed into carbs. I don’t think it’s the carbs as it ran great a month ago…now it’s starving for gas flow….so it appears to be a fuel delivery problem…what would be the sequence of tests up to tearing into the carbs? is there a fuel filter inside the carbs? remember it fires off great when primed…until the fuel spray is consumed…
ANSWER : Check the on/off/reserve valve

My 50cc mini bike starts then dies 5 secs after starting. why?
ANSWER : It sounds like you may have 2 problems

Bad gas
dpossible loose spark plug( bad compression) Solutiondump out the gas put new inRemove the spar plug and examine the plug if it is wet and black it is fouledif it is white ad dry it is not getting gasIf you can replace the spark plug if not just clean it with a wire brush put back in and tighten Finally make sure the spark plug wire is not loseBest of luck to you

2005 4 stroke yamaha 150 550hrs. normally use every week but due to surgery not used for 10weeks. Just before I went down I changed internal fuel filter, and zincs in motor. finally put in sunday. motor started fine left dock hit the power and started to come up on plane then stuttered and died. changed the external fuel/water seperator pump up the primer and started up again. with in a minute died down again. limped back to dock checked fuel filter and plug wire connections. pumped up primer and left dock went right onto plane for maybe 150yds then coughed and died. I could pump up primer and it would run but then die out. the fuel filter at the front of the engine would run dry until I pumped it up again. If it were a car I would suspect a leak in a fuel line but I can’t find any sign of one.
before we launched I put 10 gallons of fresh fuel in and added another bottle of ethanol stabilizer (CRC brand)
what proceedure should I follow to isolate the problem? I am a fairly competent mechanic as far as cars and trucks go. I don’t really want to have to take it to a marine mechanic.
ANSWER : This is going to be the fuel pump is not pumping any fuel. The primer is acting as a fuel pump. When you prime it, it gives the engine enough fuel to run for a little bit. But as soon as the fuel runs out, the engine is dying. So this is going to be a bad fuel pump.

I continually get code 90 (low/NO flow) from my 8111. I have disassembled, cleaned EVERYTHING, including the inlet port AT the pump (remind everybody to check this as stuff gets past the filter basket and will plug the pump inlet).

There is No air in the system and I get superb pressure at the outlet, yet I still get code 90. I again removed the flow sensor and put my ohm meter across the flow sensor terminals and activated the flapper and measured an open circuit. I used a heavier magnet to see if I could get make the internals of the sensor move to get an ohm reading, but I get nothing but an open circuit, ie: no measured resistance.

Can I simply bypass the defective flow sensor to trick the 8111 to think it has full flow without damaging the ‘brain’ of the system.?

Intex corp is useless at these questions. They have been out of stock on this sensor for months and are telling me “two weeks” for two months and now it’s “end of August” which I do not believe. Meanwhile I am making no chlorine while the 90 code is showing.

I love the 8111, this is the first problem I’ve had with it, and I’m frustrated that I can not get such an important part from them.

Thanks for listening!

ANSWER : Have you been able to find a solution to this problem. I am having the same issue.

I have a 2001 Yamaha XL700Z Waverunner. The compression on both cylinders is about 120, it starts and runs fine – dry. Won’t quite idle, but I can start it and rev it up fine (for a short period, of course). However, as soon as it gets in the water, it will barely run – it will start and sputter and you cannot get it to run more than a few seconds or rev up. Take it back out, let it dry, starts & revs fine. It is not getting any water in the casing that I can tell, its almost as if water is getting something wet through the cooling system that I cannot see?
ANSWER : Try cleaning the carbs and the fuel lines, filter

I have a 2004 60 hp yamaha 2 stroke outboard engine that doesn’t start or run well. Once warm and in the water it will idle in nuetral and also in gear. It accelerates in neutral but will die or lack power if I increase throttle while in gear. Engine will somtimes get to top speed but often while running at top speed engine will start to slow rapidly. Engine has full range of operationout when out of the water where there is no load on engine but is still difficult to cold start. Before these recent problems the engine sat up for several months and I had to change the impeller and spark plugs. Spark plugs fire, cylinders have proper pressure of 100, 100, and 110. I cleaned some fuel lines and filters and got new gas.
ANSWER : Every sympton you are describing here can be attributed to fuel starvation due to blocked jets and or water in carbs, when your engine dies does it die with dry plugs, or wet oily ones?

I have a problem with my machine, on occasion, not recognizing when I’m starting, and the display will not start. I have to remove one of the batteries or it will stay on forever. When it starts up, it works fine, no complaints whatsoever. But lately, I’ve not been able to use it due to the start-up problem. I put the batteries in, the display comes on, but it will not start up when I begin motion. The control buttons will not work, either. Please inform me what it is I can do to fix this problem. Thank You
ANSWER : Troubleshooting on this model is very limited to anyone but the vendor. I would recommend sharing the symptoms with a representative from fitnessquest here.
Good luck
