I am planning on building my Raptor for drag racing and I have been looking at the info from most of the engine builder's.Who should I get to build my 727 I have talked with Four Stroke Tech,Spark'sRacing,Trinity Racing,Craycraft Racing,Kenz Cycle Tech all of them realy seem to kow the raptor motor but I would like to hear the input from you guy's.What motor's you have and who built them and how you like them.I was really considering Four Stroke Tech since he isnt that far from where I live here in virginia.Any info will be appreciated.

 

You probably can't go wrong with any of those builders. I chose Kenz mostly out of convenience. Being able to take your bike to the builder is a huge advantage when/if problems arise. Judging from my Dynojet #'s compared to others I've seen, I couldn't be happier with my KENZ CYCLE TECH 727. All the the builders I spoke to ahead of time said I'd be lucky to break 55RWHP with stock carbs. I've already exceeded that and havn't even got it tuned yet. And before you guys all jump up and down about how low 55RWHP looks, realize that a Yoshi piped YFZ only made 38RWHP on the same dyno.

 

Out of those the only one I've dealt with is Craycraft and the work. service and turn around time were excellent. I would highly reccomend them.

 

I personally would go with Craycraft. I haven't heard of a Sparks 727 and if the Trinity 727 is anything like their 686 I wouldn't touch it. All I know of Kenz is what I've heard from RaptorAZ and he seems happy with it.

 

Same as Sixsixt, I've only dealt with Craycraft and haven't regretted the decision one bit.

 

Just my 2cents worth I don't have a rappy but have seen the craycraft rappys run, they are fast I mean real fast & dependable. when I get my kit for the DS yes DS I have no problem taking my motor to him for the build, I have never heard any neg feed back from anyone, not that the others have but customer service is high on my list. again for what it's worth thats my 2cents!
