Hey guys have a trip planned for little sahara this coming week. Im jetted pretty close to spot on according to my piston wash at 75 degrees. The weather there looks to be 45-65 degrees during the day there. Im wondering how much I should jet up. I really don't wanna burn down my motor out there. Mods are 4mil long rod, HJR dune hillshoot port , ported cases, 185-190 compression/straight 110 fuel, +6 timing, vforce 4 reeds, Cpi inframes, 35 pwk carbs with pods. jetting is 155 main, 50 pilot I believe and needle is one notch up from middle position. Just bring a couple bigger mains and be good?

Hey guys I’m planning a trip out the little Sahara. I have a 4mil stock cylinder, dune ported. 185 psi 35 pwks timing plate with CPI pipes. Wondering what is all needed to go out there, sense this is my first trip. What are good paddles that won’t break the bank. I live in central Wisconsin. Will I need to rejet for the elevation difference?

Larry I have and it’s deffonly rich on the main. Just trying to get a starting point or as why it’s not idling very good. Now like before the pipe comes on it has a big flat spot but will pull through to the pipe. Only does it if your not Reving it hard. I’m trying to figure out if it’s s rich bog flat spot in midrange or if it’s a lean one. Which way on the middle does what. I get so confused. From the small end that goes into bottom of carb if your raise the clip you lean it out?

Hey guys my brother recently bought a banshee, it’s suppose to be a 4mil stock cylinder. 155 psi both cylinders 35 pwks with pods t5 exhaust. No timing advance. We are at 1200 ft for elevation isn’t running worth shit. It has a 168 main, 48 pilot and clip on 4th groove. It idles rough and hitting harder on left side. Carbs are synced. I moved clip to middle didn’t make a real difference. Is he that rich on pilot.? I have a 4mil with cpi dune hillshoot port timing plate 190psi 35pwks vforce 4 reeds and I’m at a 155 main 50 pilot needle in the middle and it runs good.

Just bought some 35 pwks, looking for a starting point on jetting. I have a 4mil stock cylinder dune hillshoot port, timing plate cut domes for straight 110 vforce 4reeds with cpi inframes. Elevation is 1200 will be riding in 70-90 degree summer temps. Had knock off 34 pwks and hjr had a 155 main 50 pilot and clip on middle I believe. Just wasn’t sure how much the jetting changes between these two carbs. Thanks

Looking for a good set of 35 pwks. Got a 4mil with knock off pwks and not having much luck.

Thanks for help guys I think my breather was pitched rerouted it and blew in it I could hear air inside case. I did put the old seal pack in and ripped it hard didn’t come back out. Hoping it will be fine for the ride.

I’ll go check, figuring it’s building to much pressure. Seal looks good motor only has about 10hrs sense full rebuild. Do I need a new seal?

Hey guys having issue with my banshee and don’t know we’re to start. Motor was redone by hjr runs amazing. Other day oil was spraying out of my front sprocket area. Got it home and found out my sproket seal popped out. Took everything off seal looks good. Put everything back to see if it would do it again. Popped back out once motor got good and hot. What is causing this.? Pressure in my case? Was hoping to ride this 4th but not looking promising. Any help would be great

Thanks, I’ll have to order just need a heavy duty clutch sense I use it a lot with hillclimbs

Hey guys have a question regarding clutches and springs. Recently got my motor back new whole new clutch besides plates sense mine were good builder said. Everything is in adjustment my issue is I seem to be having a lot of clutch fade, whether I’m slipping clutch or just riding hard on the black top. clutch don’t slip as of now will heavier springs take this away.? Oil is changed regularly I do have some mods but not built to them moon bike is, 40over dune ported vforce reeds with stock carbs and pods i do a lot of road running and hill climbs

Toy breaker question for you when you say 2clips from bottom is that the blunt end or point end been having issues with mine with 30 pilot needle on 4th clip or second down from blunt end. Won’t run decent down low with those settings unless air screws are almost seated

Ya Kevin ported the cylinders knowing I was gunna be running t5s these pilots were in when I bought the quad which was along time ago back then it just has t6 pipes and lid of airbox. As far as the needle what is the leanest the the first clip from blunt end.? Sorry I’m new to this jetting to get it really on target always just messed with the main on my race sled but banshee is deffinly little different as far as the needle and stuff.

No I havet tried a different needle, Kevin at hjr built my motor he suggested with my set up should be running between 340 and 320s. Plugs seem to like the 340s for me I do a lot of top end riding so I’d rather be rich up top then lean. road today and ran awesome but that’s with the air screw quarter turn out from seated if I go anymore it will stumble from idling around to 8th throttle. Runs amazing up top. And right now I’m running t5s with this set up.

Ya it doesn’t seem right. Don’t have any air leaks and bike runs amazing from quarter throttle on up. Just if your in that one throttle ranch it cuts out and burbles unless air screws are in almost seated Sent from my iPad using Tapatalk

Or is it the other way if you have to have the air screws almost all the way in you need a bigger pilot? Sent from my iPad using Tapatalk

Thanks for the reply I do have some 25s I could try. Like I said tonight I had the air screws all the way in maybe alittle off seated and it was good. From what I read that means I have to big of a pilot.? Sent from my iPad using Tapatalk

Hey guys need some advise with my carbs. My bike is dune ported stock stroke vforce4 reeds 40over and stock carbs with pods, running pump fuel. Ive had this issue before I got my motor ported there is a miss/cut out of idle to 8th throttle. I’ve always left it but trying to get it tuned perfect to get the most out of my port. Elevation is 1200, carbs are 340 mains/ needle on 4clip or second down from top. And have a 30 pilot. This problem gets better the farther I have the air screws in if I got 1.5 turns it gets worse. Do I need a smaller pilot? It’s just in that throttle range from there all the way up top it’s a arm puller.

Thanks for the advise guys I believe his air screws are messed up along with what you said carbs out is sync I messed mine up on purpose and had same running results.

As everyone knows I got my motor back from Kevin at hjr. Stock stroke dune ported 40over reeds and pods. Motor is a arm puller for what's done. Raced my buddies 250r last night and all I can say is wow. I killed him with those mods. Is isnt ported or nothing but piped reeds and no airbox. It wasn't even close from start to up top I can't imagine how hard the 421s pull. Straight up addiction and worth every dime I spent. Brap on 👍

Alright guys and will there be any difference in performance with the 28s and pods over the stockers?

I'm looking at upgrading my carbs. My motor is stock stroke dune ported 40over stock carbs and pods t5s and reeds. My question is will 28s make a difference or do I need some 33s. Also with either of those carbs do I need different intanks

Need some direction, my cousin has a 87 banshee ran fine down the road last weekend and then on the way home went to running on one cylinder. We put new plugs, went though his carbs he even got new ones. Reeds are good, compression is good. It will rev decent once you get it started and give it gas past half throttle. Once you let off the gas it dies . Right side is hot left side just warm. Bad stator or Cdi? He's lost on what else to check.

Ya I wish I would have, just didn’t have the extra cash at the time, damn lay off season. How hard are those timing plates to put on and get going? As far as the coolhead what size domes?
