Hitting the rev limiter a little too early?

Recommended Posts

I'm still trying to my bike's jetting dialed in perfectly and it's at a point now where I'm quite happy with it except for one factor, it seems like the rev limiter kicks in way too early.

 

I clocked my bikes speedo with GPS to read about 5 km/h high so I adjusted the speeds:

- 1st: 60 (kph on bike) ~ 56 kph = 35 mph
- 2nd: 84 (kph on bike) ~ 79 kph = 49 mph
- 3rd: 100 (kph on bike) ~ 95 kph = 59 mph
 
With no freeway close to where I live I can't really test out 4th and 5th's limits very easily without risking jail time.
 
Are these what I should expect from the bike? It's an 09 with stock CV carb, corked MRD SSW, DJ jet 155 with a 3x3 that was done too big and I have tapped back down to propper size.
 
Is this the reality of 400cc's or should I expect more kick from this pony?

You're gonna hit the rev limiter if you try. Just remember, it's a single cylinder 400cc dirt bike that makes 33hp stock. It's not an arm stretcher.

Rev limiter kicks in to early.....lol........

 

It's there for a reason o'l mate, if you want it to rev more and destroy your engine I can show you a way to disable it .... :smashpc:

 

Those speeds are fairly decent on a general purpose single 400cc with a CR gearbox...

it's made to grunt and pull nicely to around 7500rpm, then it tapers off. if you change cams and timing of them, you could move the power up to a higher rpm, but then you're at REALLY FAST piston speeds, and i doubt the oiling system is up for it. 

 

btw, living far from the interstate is this bike's dream territory. enjoy it, interstate SUCKS.
