Quick question on RPM's

[Texan32]

With a stock CDI, how high does the 400 rev?

I'm thinkin like 10,200 but I am not positive on this,,it's not any higher than 10,200 I'm pretty sure about that.

i thought it went to 11,000:huh

I am almost positive that it is 9100 and that is what a Honda page said.

YOu might be right,,cuz I think the number I put in there is with a WB CDI installed now that I think about it..

[DESDAK4]

Yeah because the WB CDI takes it up too 10200 or something like that.

The reason i ask is because i would like to put an analog tach on. I saw some race tractors (beefed up riding lawn mowers) this weekend that had some really sweet tachs on them. I thought they went up to 16 grand and the guy said they got them at JEGS. I just checked the jegs web site and nothing...i will check AUTO-METER's web site when it is back up. But, i also just ran a google search and apparently High-lifter sells a pretty sweet looking tach too. It's 2 5/8 inhces round, tops out at 11 g's, is backlit and weather proof. Looks like they are asking 130 for it. I'm really thinking about getting one. Has anyone else seen one of these? Anyone running one? Someone else go to http://www.highlifter.com/store/tach.html and tell me what you think. I was thinking you could mount it in the dip in the front plastic between the nose and the finder....

It looks pretty good, I like the idea of having the hour meter.

im fairly sure it cuts out at 9600 , which seems to be too low now that i have a pipe. i always find myself hitting the limiter in 2nd and 3rd gear too easily.

i am pretty sure it is 9,300 rpms becaseu it said that the white brothers gives almost 1,000 rpms and that boosts it up to 10,200. I am pretty sure that is right
