FASTOYS

I agree with Loco on that one. Plus the billet ones wiegh alot more and we all know we wanna go faster. ha

We have built both but prefer the cut domes and ported cyls for 4mm. To see much gain out of a 4mm , you really need the cyls. ported, then you will have a BIG smile on your face !

Thanks Jbooker ! We also have the 4mm Hot Rods for $430 that comes factrory trued/welded. Rather than buying one and sending it in to be welded most of the HQ sponsors carry them on hand or should ! Maybe your stock crank can be trued/welded??

You will need a Metric Cresent wrench and Left handed deadblow !! No really, Common metric hand tools, a Banshee flywheel puller (IF tearing down mtr), rubber mallet, and a impact wrench will really help out a bunch.

It really depends on how it is ported for stock stroke. Who did the porting on it before ? They would be the ones to ask as they did the porting. Generally all the ports will need changed to go to a 4mm and have it run optimal. The transfer height is usally alittle high on a stock stroke dune port to work correctly with the 4mm and you will need to lower the ports for a 4mm along with changing other porting. Will it work just bolted on ? Maybe, but prolly not effiently . : ( Need to get with a builder on that one. Get with Kevin, myself , or any of the HQ sponsors on here for help as a 4mm requires a bit more work and checking to make sure you get a great running combination !

They work flawlessly ! Beware though that the ones i have seen on ebay are not the same as they dont come with both adaptors to fit all size carbs like ours do, only the small one !! http://www.farmandsandtoys.com/partdetail.asp?partid=59

I have some cylinders , pay the frieght and they are yours next day !

LMAO, that was my thoughts exactly but the kids are stuck home too. : ( Guess they need to go sledding for awhile huh? : )

I apologize for any confusion as Im not sure what Nick quoted you as he was without Cody and I and was running ragged, but the cheaper one is $19.90 . http://www.farmandsandtoys.com/partdetail.asp?partid=143 The GOOD one w/needle bearing lever is $31.90 http://www.farmandsandtoys.com/partdetail.asp?partid=144 Plus shipping to both. We are in a blizzard so will prolly be closed tomorrow but your welcome to email me or call and leave a message, we will get back to you! : )

Yes and on any sport quad.

Just give us a hollar in the morning or email and we willl get you taken care of.

Some YFZ rider needs this head as that is a killer price for a ready to go head. This will pick you up at least 3-4 hp and maybe more depending on cam choice. This head will work great on any YFZ and still has stock size valves.

You will love it! Much smoother easier pull. Make sure to lube cable also!

If your on a budget than porting your stock cyls will be the cheapest route. If you have a few extra $$s the Serval Cub will work awesome for your type of riding!

Thanks for the props.. I had heard from others that you were running very F.A.S.T. out there! Our turnaround at this time is about 1-2 weeks.

Do all the bolt on's first then port it. I would go with adj. timing plate, milled head or F.A.S.T. head, and maybe some V Force reeds.
