I currently have my motors top end tore apart. Awaiting the arrival of Bo's port and polished head, new piston and cam. Would it be worth putting in a stroker crank in at this point? Is it hard or should it be paid to get done. It seems like alot of work having to split the case and take tranny gears out? Any answer would be much appreciated. I would rather spend the money now while its this far into the project.
If your going to do it, now is the time since you already got allot apart :thumbs:
I've heard its not an easy one to do. I wouldn't mess with it unless its something you feel comfortable with.
It's a time consuming job, I just did another one yesterday. It went way faster for me the second time around but it still takes some time and patience. Not a real tuff job to do, just time consuming and you will need to pay attention to all of the little details.

Troy, since you've become quite the master of putting in these +5 cranks do you think you could ever do a write up with pictures? It would be nice to see how its done.
Personally, it depends on how comfortable you are with your mechanical skills. As mentioned earlier, it is a huge job and you will need a good clean bench to lay out your parts.
I did my own and had no prior experience with a Raptor motor. I do however have extensive automotive and street bike experience.
NOTE: IMO, the BEST upgrade I have ever done to the Raptor was putting the stroker kit in.

So where do you live? My engine is in the garage waiting for you.
:lol:
A good work bench is a must to get this done faster. I went out and bought the crank splitter tool and the stator puller tool and a nice stainless work table that rolls around the garage for this second time around. Another nice thing to have is the really big zip lock baggies. I put everything from the left side of the engine in one and everything from the right side in another one. I also use little ziplock bags for the smaller stuff that I want to keep the bolts straight like the oil pump, water pump, crank gears, counterbalancer gears, etc. This will save a ton of room as all of your bagged up parts can hang on the wall until you're ready for them, and when you are you will use everything in the bag and not worry if you are missing something. It also makes the job seem alot easier doing it one bag at a time. I love my new work bench, I keep all of my tools in the bottom and roll it to the bike and everything I need is within reach, that alone saves a couple of hours on a job like this. Next time I do one I'll take pics of everything and do a good write up on it. I don't know if everyone should do this project but I do know that these stroker cranks are the way to go, way worth the time to put it in and in the case of these little plus 5 Hotrod cranks, they are way worth the money too. Time will tell if they are reliable as the more expensive units. I will tell you guys they are nicer than a stock unit so they should be fine.
I just finished putting a stroker crank in the wife's Z400. It took me forever, not because it was hard, but because I'm a lazy procrastinator. I managed to do it without the splitter tool, but the flywheel puller is a must. As was already mentioned, the workbench is a necessity, I used two benches as I had two motors apart and didn't want to mix the parts (one motor was a donor for the broken case on the "good" motor). You definitely need to be pretty mechanical to handle a job like this. If you don't have a big box full of tools, I wouldn't really recommend trying this as a first big project. Don't even think about it without the full shop manual.
You used a shop manual? :confused:

OK, do you need me to bring my wife down to keep you out of my hair while I install the crank?
Hell yeah! You can start installing mine from here on out :clap:
Go for it!!! The experence will do you good,YOU ONLY LIVE ONCE!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! :clap: :thumbs:
Installing a stroker Is like losing your virginity.As long as It wasn't her.

DAMN! It would take one hellova stroker crank to get that one moving :confused:
Troy, how long have you been running the +5 crank?
I've had mine in since Labor Day.
How many hours do you think you've put on it?
Probably 40 to 50 so far

I bet they are all drag race hours too.
I know if I were'nt getting into XC racing I would be shipping my bottom end off to Troy with a NEW, CRISP one dollar bill inside :thumbs:
The +5 would be great for xc, just a little crazy out of the turns.
:rofl:
I don't think a small stroker crank has any real disadvantages anywhere, but it's probably not needed at all for xc, the rappy has plenty of power for that and it comes down to rider ability more than anything at that point.
This probably wouldn't be something I would like to tackle myself! How much do you think the dealer would rape me for to do the bottom end?
Were are you located? Isn't there some local talent on this forum to assist you? Or even a local performance shop for quads. Screw the dealer.
None, that Im aware of. Kennewick, WA.
Any good motorcycle or atv shop should be able to put in a crank.

Get ahold of Rooster Built in Auburn WA 253-333-8533 they can do anything you need on your 700R and give you a first class dyno tune as well..... :thumbs:
Im with Randy on that. It would be worth the drive to drop it off with David at Rooster Built and pick it up tuned and ready to go. You wont be disappointed.
For sure! I will be giving them a call as soon as my builds done. I think I do the stroker next year!
This is the first I hear about a stroker crank for the 700. What are the benefits, more torque throughout the range, how much more? Does the 11:1 piston and CNC head match the stroker gain? Does anyone have before and after dyno curves? What is the displacement after the install? What are the drawbacks? I do mostly trail riding but I like to drag race with friends. I would like more power everywhere and definitely don't want to lose any more low end. I am looking for the most bang for the buck and want to do it right but not lose any reliability. I plan on installing a custom mapped dynatek ignition next but then what after that? ??? ??? ??? :help:
