uman1030 Posted December 28, 2013 Report Share Posted December 28, 2013 Have a couple questions, purchasing a 4 mill Serval cub from F.A.S.T and some VF 4's and i was wondering if i should use my 35mm pwks, would this be beneficial or would this rob it of some low end throttle responce? Iif i do use the 35's i know i can get intakes to fit obviously but if i wanted to use stock airbox (no lid) are their boots that can be bought that would adapt the 35 to fit the airbox and would this be conterproductive by decreasing airflow too much. Athough Id prefer not to use pods on this trail bike as it does occasionally see the random water puddle and soupy mud at the areas I ride. i try to avoid these but depending but sometimes its almost impossible. Im not completely against pods especially if its the best route but i feel that do to my riding environment if possible i should try to keep my filters as dry and mud free as possible for obvious reasons but its difficult at times.Especially at "the Mounds" in MT Morris Michigan. Most of the spring and fall is super wet there especially the wooded areas never seem to dry out. what are your thoughts on these questions, any advice would be appreciated.

WINDYCITYJOHN400 Posted December 28, 2013 Report Share Posted December 28, 2013 PODS FTW. Ditch the air box. Get K&N pods with outerwear's. Airbox is just going to kill the power of a motor that big. I've ridden the entire Badlands after 2-3 inches of rain and they work fine. I even rode the entire length of the river….IN the river! Once or twice a year I'll hit a big puddle and the motor will die (usually after I'm all the way thru) and I'll have to sit for 3-4 minutes till the outerwear's dry off. But that's when I'm telling the "Did you just see that?" story anyways. Quote Link to comment Share on other sites More sharing options...

Was a big water filled trench in trail i didnt know about not enough time to stop i just leaned back and wheelied thru it and this was with box and no lid but later inspection showed filter wasnt fit right alowing a gap.

Well that's a big difference compared to wet filters. Wetting filters just smothers the motor. Submerging filters and hydro locking of quenching hot parts is a fail either way. An air box is just a bathtub your carbs sit in. You dunk that air box and you'll be in deep shit too! The Carbs can suck the air box empty faster than that little drain on the bottom and drain it all out. mild bolt-on modded motors lose power with the air box lid on, so a Serval is going to choke! You wanna treat your machine like a jet ski……buy a YFZ450, leave the air box lit on and don't do any power mods. Otherwise…. K&N's with the water repellant Outerwear's is the ticket.

K&N's with the water repellant Outerwear's is the ticket. ya it wasnt submerged at all. puddle was about 6-8 inches deep max it wsa from a truck offroading at our track. where i ride mostly is a track built by the guys from Magics motorsports in watorford michigan its across the street from them in an empty square mile lot of woods and fields. theres an mx track and also and also some endurance woods trails for bikes as well as a bunch of two tracks. i just got a little spray off it. so im going to assume that cause the gap in the air filter it took on alot more water then a properly fitted filter would let in. Also i dont run a lid on the airbox. its completely open with a K&n filter i may just run pods then like i said im not opposed to it. sure would make working on carbs easier. How about the 35mm carb question do you think this would decrease low end throttle response and do you think its necessary to prvide that much fuel to the serval?

WINDYCITYJOHN400 Posted December 28, 2013 Report Share Posted December 28, 2013 35PWK is the preferred carb for that motor. Quote Link to comment Share on other sites More sharing options...
Starwriter Posted December 28, 2013 Report Share Posted December 28, 2013 While we're on the subject. I know there's water repellant and non water repellant outerwears. Is there any disadvantage to the water repellant outerwears? Do they impede airflow more? If not, why do they even make the non water repellant ones?

hoppedupandcutdown Posted December 28, 2013 Report Share Posted December 28, 2013 I've looked before and their website says the water repellant ones flow the same air as the regular ones, I've couldn't find anything on why they offer both. They also say the water repellant-ness doesn't last but about a year, a can't be re-applied. Quote Link to comment Share on other sites More sharing options...

lms1977 Posted December 29, 2013 Report Share Posted December 29, 2013 I made the mistake of trying to use a airbox with my 465 serval When I put pods on it was like night and day. Quote Link to comment Share on other sites More sharing options...
uman1030 Posted December 29, 2013 Author Report Share Posted December 29, 2013 ya taking others advice and not using airbox, ordered pods as well as a plethora of other stuff. Quote Link to comment Share on other sites More sharing options...
Abe Posted December 29, 2013 Report Share Posted December 29, 2013 Just a FYI. 421 Serval is actually intended to use a .020 base gasket. You may be stuck with the .012 if domes were cut for it but just figured I'd let ya know. Quote Link to comment Share on other sites More sharing options...
uman1030 Posted December 29, 2013 Author Report Share Posted December 29, 2013 ill make note of this, Jeff at fast is taking care of me and cutting domes etc. I have faith he will set me up well. Quote Link to comment Share on other sites More sharing options...
