Changed the exhaust gasket yesterday and today another problem I'm in 3rd or 4th and when I'm reaching near red line on a straight it's just holding the revs there but sounds like power is being losses anyone think of anything it could be ???
It's got 5, I'm the past though I've got to 4th and managed to push it and it keep gaining power then knock into 5th maybe it's just me but I have been riding to and from work without an exhaust gasket too :/
Because you replaced the gasket, the bike is actually running better. If feels different because you have got used to how the bike rides when fucked.
dont think ive explained it properly when its been near the red line previously its held the power if not gave it more but now it seems like it losing it instead
see this is difficult to explain it used to hold it at 10000 rpms in stead its giving in at about 8000 to 9000 and not wanting to push anymore like it used to and ive also uprated the front sprocket to give it more to[p end but im not getting anything :/
Switch back to the normal sprocket and see if it returns to normal....if so....youve found your issue. If not, youve lost nothing bar a few minutes.
That's how it works. Changing the number of teeth changes the sprocket diameter and the final drive ratio. What is referred to as lower gearing has a higher numerical ratio and vice versa if you're looking for another reason to scratch your head. A smaller front sprocket or larger rear sprocket, i.e. lower gearing, raises the rpms required to go at a chosen speed and gets into a higher torque and horsepower section of the engine's power band as the mechanical advantage of the rear drive increases. It also may increase fuel consumption, vibration, noise and engine wear plus limit the top speed. A larger front sprocket or smaller rear sprocket, i.e. higher gearing, lowers the rpms required to go at a chosen speed and reverses the above changes. Note the changes "may" be noticed. Changing the power band and shift points by a gearing change can do unexpected things. For example, a long distance tourer may try higher gearing for better fuel economy by lowering the engine rpms but find no improvement. The engine will probably have lower power and torque numbers at that lower rpm and require a larger throttle opening to compensate. Chain drive bikes make sprocket changes cheaply and easily enough to encourage experimentation. I tried a larger front sprocket once and decided after one long trip that I didn't like it. The power reduction required using a lower gear in many situations than I was used to. http://www.gearingcommander.com/ lets you plug in different gear sizes to see what rpm changes occur.
Cheers mate someone who has same bike as me suggested it to more top speed as I have A roads to get to work a lot so I thought the more top speed would help but I don't know if it's made it worse do get a lot of vibration to at the higher end of my revs and doing a lot of short shifting so I doesn't vibrate lol thanks for the help
Lol this thread is epic. +1 Front sprocket: Slower Acceleration Higher Top Speed =0 Front sprocket: Stock Settings -1 Front sprocket: Faster Acceleration Lower Top Speed You cant go +10 front sprocket for Ultimate top speed of course, because the bike wouldn't have the power to even move the bike along. Your bike is running out of uumph. - Change to stock sprocket.
Ok I changed sprocket back to stock and changed my plug to a previous one that is compatible with the bike, in case it was the problem but no still nothing I got over taken by someone on a bloody moped!!!
