have not been able to get on this site since friday sometime, it seems to happen about every other day, i'm about ready to give up on this place if something doesn't get fixed around here. there are other sites that never go down.
got the pipe and headers finished, vdi installed, nine 1" holes drilled in the top of the lid, the main jets that i had to drill out to 3/32" cause they don't make them any larger than 200's, turned the fuel screws out two turns stock is one, and it hauls. on flat ground i hit the rev limiter in under 500', gps says 58.3mph. it pulls hard all the way, in fact once the belt has reached the top of the primary and it starts to rev higher it feels like it accelerates even faster, its still pulling hard when it bounces off the limiter. a higher clutch engagement rpm will greatly improve the acceleration. the full exhaust system i built made a huge difference, the top end power is amazing. earlier today we shot some video of my teryx drag racing a friends rzr, its no contest the teryx pulls away from the start and keeps pulling all the way. we marked out 550' and at the end its a huge gap. the video was supposed to be up today but we had some issues, we should have it taken care of tomarrow though. i will post a link when its ready, we filmed several races!

YouTube - Teryx vs RZR

in the first one the camera is about 500' away, as i pass the camera you can here me hit the rev limiter, gps read 58.3mph.
the second one we are on a driveway that is only about 300' long so we had to brake quick.
the rest are still loading

Not really, its been dynoed several times that equal length Muzzy headers make more hp than any other pipe on a built kawie V-Twin. The only comparable true duals are the LTE's, but there twice as much as Muzzy!

The FST 840 kit is right around $1500, includes Hi-Comp pistons, sleeves or possible cylinder exchange, custom grind FST cams of choice, heavy duty valve springs and I believe the head gaskets. The FST standard bore kit, includes everything above execpt the sleeves or cylinder exchange and is right around $800. I believe he has the kits in stock ready to ship. Check with Mickey at FST to be sure. He hasnt dynoed this setup in a Teryx yet, but it should be about double the stock output. Dont forget you still need a good exhuast and cdi. As far as clutching, I think Chase is still stock but will be experimenting in the very near future.

i am going to send the primary drive off next week for mods and machine work, need to figure out what is available for the clutch to raise the engagement rpm also. this thing should be capable of 67-68 mph by the end of next week.

i talked to him today also, after seeing the video he posted on one of the other sites telling me i need the clutch work. i ordered the primary puller bolt and the primary spring today that he instructed me to. monday i will next day him my clutch and will have it back on thursday. he says it will accelerate much harder, he actually said it will pull the front tires off the ground. the machine work he does will give it 20% more overdrive, that translates to about 75mph. i also order the programer for the VDI so that i can up the rev limiter, cause its just starting to get into the power at 9200rpm. next week i will post more drag videos and film the speed on the gps if i can find someone to ride along. maybe even race my own 523YFZ on the street just for fun, might be a good one!
