well i had an o4 raptor piped jetted filter and the most i could get out of it was 88 so its possable he may hit 100 but i doubt much more than that.however they are fast as hell on the whole shot too amazing torque but i like my ex just as much so hell give him a run see what happens :devil:

[Chin_Chilla]

no hell beat you

if its a 720 its stroked(correct me if iam wrong) a 686 is the highest u can get to with out being retarded iam pritty shure but what do u know that jus what ive read. anything is possible with the right gearing. i doubt he went 130+ cuz the record like 147 on a rocket powered raptor. and u will most likly get beet if your ex is mostly stock.

yea world record is 149. i say his does high 80s mid 90s but soon as i get the 25 stiches out of my hand its on haha were going 2 race on a mx track so will c what happens

There is no way in hell it will go 130mph even if it has a 720 stroker. That thing would have to be geared up so high to go that fast you would have to push it to get it going. It will only rev so high. What is his gearing,tire size,cdi rev limiter? I would laugh everytime he says that it will go 130mph. People think that atc250r's go like 90 and ****. They prolly hit 75 at the most.

Bore alone won't make a trike/quad go any faster on topend then before. It will just get there quicker.

I can testify that with 14/36, 20" tires, and a hi-rev pipe atc250r's will go in the mid 80's, any faster I have serious doubts. Getting there may feel alot faster. That raptor MIGHT go 90 at the highest, but it better have aleast 1 tooth higher in the front and about 4 down in the back. engine mods have nothing to do with top speed, rpm x final drive ratio(with the tranny reduction gearing and tire size calulated in) will calulate top speed.
