Upgrading my 421 serval

[WINDYCITYJOHN400]

Taller tires should help.

 

Feather the gas or clutch out of the hole. (Once they start spinning, they keep spinning.)

 

Move butt to back of seat. (Keep a close eye on that front end tho.)

He weighs 73lbs... Body english will not help him .

[dirtydownunder]

how much air pressure ya running ?

[locogato11283]

Tire pressure isn't going to matter much if any on this motor.

 

It's going to need more gear and tire.

 

A set of 22" and 17/41 might get it done. M

 

Ryan weighs about 140 pounds. He doesn't have enough ass to him to get the power down.

88/50 should hook up better than that on the street, i would have thought anyway.

mine should be around that maybe a touch lower on the tq, and im 147lbs, 4,5,6 just does wheelies. with razr2 on 3psi, tho, on dirt it sucks ass.  and just spins.

my old 465 serval with regular yfz450 rear tires would spin 1-5 on pavement with my 320lb ass on it I had a +8 swingarm on it

 

glad to see ya got it running

HP and TQ, what is that 10serval putting down RJD?

 

I posted the dyno chart in the Dyno Forum.

 

It's the one where Snipers kicked the shit out of everything else.

at 2 psi in my razrs i can pitch it sideways in 6th and lay serious rubber. its serious fun but the tires are a serious fail.

[RagunCajun]

Damn that's some bad traction problems. Traction isnt looking good for my build. may have to keep the pro wedge's on my bike. damnit.

[dirtydownunder]

As serious as your seriously serious, serious comment is seriously serious, I don't think your bike could lay rubber let alone seriously lay rubber in 6th gear.

[Coupelx]

of course it wont. every serios person knows cheetahs are a serios joke.

Cheetos

Iv been running 3.5 psi in my tires. I'm sure 22" tires are a must and I will see where I'm at with those before I toss on a 17 sprocket. I'm worried it will make the trails a little rough to ride if I'm sitting that tall. I'll try different things I guess. Maybe a 39 rear sprocket with 22" tires?

I want to see some video. lots of it
