I am trying to find out who is making big bore stroker kits for the Raptor. I called Speed Tech today, and they told me their kit is not available yet. Can you tell me the name(s) and number(s) of anyone producing such a kit? Thanks in advance for any help you can provide to me.

 

You need to call FST (Four Stroke Tech) and you will talk to Mickey. He only takes calls between 3 and 5 CST. Unfortunately, I don't have the # with me today. If you have the last issue of either (can't remember) Dirt wheels or 4 Wheel atv, they did a write up on his kit. I spoke to Mickey on Friday, last week. He said his kit is 40 over bore and I beleive it was a 10.25-1 compression. As you would expect, he said the Raptor is now unbeleivable. I am looking for a stock bore, high comp piston for my Raptor but, have only found Powroll offers them. I always like to speak with several Companies to see what their veiws are. If you happen to know of others offering a stock bore high comp kit, let me know. I hope this helps, find the last issues of those magazines.

 

Powroll told me that there is a problem of breaking some kind of gear when the power gets pumped up enough with a big bore or stroker cranks.

Does anyone have an idea of what gear this may be? They were a little secretive when telling me about it.

 

swytak,

I haven't been able to locate the number for 4-Stroke Tech; it must be a brain fart or something. Anyways, I'd really appreciate if someone could post their number here. Thanks.

 

BluByURaptor8,
Well the best I can do is get you the # tomorrow. I did speak with a couple of other companies today. Speed Tech, is working on some copression kits but won't be ready for atleast 6 weeks. They want to throughly test the kit prior releasing it for sale.
Vito's, aren't even working on anything for the Raptor.
Trinity Racing, is working with a European company that has been working with the European version of the 660 motor. This motor has been around for atleast 6 years. Trinity, will not offer anything for atleast 4 weeks. Again, they want to do extensive testing prior to releasing the kit.
Another company you may want to talk with is Bike Worx. Again, I don't have the # with me today. I will get the 2 #'s for you tomorrow.
As it looks, these kits are in the R&D stages and seem to be a bit premature at this point. I'll let you know if I find anything, later.
Good Luck!

It will be interesting to see how Big Bore Raptors hang with Trick Banshees in the Dunes.

 

Bikeworks in Maynard, Massachusetts sells them also. Not sure on the number but area code is 978. Call information to get it. 978-555-1212.

BluByURaptor8U,
OK, I got the #'s for you.
Bike Worx is (978)897-0044
FST is (814)842-6159, Mickey is who you want to speak with. They only take calls from 3-5 CST and you have to keep calling because you will get a busy signal, due to the times he takes calls.
When and if you get any info, post it for others to see what is available.
Good Luck!

 

Thanks for the info. guys! I'll let you know if and when I uncover any good information. Take care all.
