9500 average stock maximum RPMs.

 

 

The usable RPM range stock is probably 5000 to 9000 or so.

ya so 9500 is the max for a stock one how baout a moded one pretty moded out liike a 4 mil all that stuff so when u hit the powerband its about 5000 to 9000 what are new 4 strokes compared to that are they that high for stock

well, a 4mil will do less than a stock stroke, the bigger the stroke, the more torque and LESS RPM.

 

so if you put like a -4mm, it will do more rpm... a modded banshee with top end pipes would do about like 1 or 2k more i BELEIVE.

okso if u pipe it it might get up in the 10000 to 11000 range

Usable power is finishes off before 9K. 10K is a good spooling motor, 11K is getting it on a small bore motor.....

allright so they are more then a craptor or anything like or no

[jbooker82]

My patriot drag ported 4mill.stopped making power at 9100 to 9200 with cpi pipes and pwk carbs.

[mopar1rules]

i think the raptors are limited by the OEM rev box to 7800 or so. i could be wrong tho. i know they have big gun rev boxs to add more max rpms.

[dirtydownunder]

the yfz 450's rev higher than the yfz 350's.

some 450 rev box's have a rpm limit of 11,700rpm.

 

but only 2 strokes sound good up in the revs

Thread is 10 years old. But in case somebody else wanted more info.

My Banshee is stock bore stock crank, T5 exhaust, shaved flywheel, 19cc coolhead domes. 93 octane.

Power band hits at 5500 and starts to drop off at 11,000 I can run 13,000 but you start to really notice the power loss.

 

Also! Once engine temps get over 150. You will notice decreased performance. And anything over 200 it's a real dog.

What are you changing to get up to 13,000?

[Deets]

For stock bore and stroke I’d think they could make HP at more rpm than 9,000. 
That would be determined by the pipe at what rpm peak power is made. This would most likely result in poor power down low I’d assume though.

your t5s carry peak power up to 11 k?

Probably has a tach in 1 pulse per cycle mode lol.
