hey guys im getting my esr 350 cylimder back next week from neil. im super stoked as this will be my first big bore. now im tryna see if anybody has a setup like mine and what are you guys running for jets, gearing, tires, ect. ill have a trx5 pipe, all around porting to match, 38mm a/s carb, vforce2 reeds, airbox with no lid. i think i have 14-38 right now for gearing. any suggestions on where to start for jetting pilot and main?? also whats the power of yalls bikes feel like?? that way i can dream about something!! im hoping my arms rip off at the shoulder and are still attached to the handlebars!! woohooo
-
You will start by loosing the ability to kick the bike over if you don't have a cr ignition. Just a heads up after many broken kickers and boots! I was using 182 main 52 pilot and a DGH needle on the Oregon dunes
-
well terrific news tony thanks!! lol. i have read that before though. thats a future buy but for now ill just kick away!!
-
Keep with Uncle Neil's suggestions. He is the King of the East! :respekt:
-
Oh! And by the way, you are going to be grinning so much, your cheeks will sore! :excitement::Boobies2:
-
neil just gave me a huge list of jets to buy as he is on the east coast and im on the west. he didnt know where i should start. tryna see if there is any duners that had a setup like mine
-
I fire up my nate built 370 on a stock ignition with one or two kicks on race gas
Mat Shearer just built a 363 on a stock ignition aswill making plenty of ponies
-
ahhh.. this my man is great news!! great to hear!!
-
follow tonys approx jetting, hes pry much dead on. your pilot will probably be 52, start a couple sizes bigger on the main and then work your way down. then you should be good to go! dream about the cr ign btw LOL best investment i made!
-
What type of riding was the motor ported for?
You'll be fine if the OEM ignition is in good condition. I haven't experienced any kickback with mine
-
it has all around porting for low-mid-top end.. i ride trails and wanted some top end for the dunes..

One of my ATC's is powered by an ESR 78mm (350) big bore with race fuel dome and Eddie's TRX9 porting, fed by a 38mm Airstryker and ESR reedblock. Exhaust is ESR ATC5.
My jetting was a #52 pilot, DGH needle and 190 main. I still had a little more room to lean the main a size or 2.
I have another ATC that is a stock engine, stock porting, with a PWK36, Boyesen dual stage reedblock and FMF Fatty exhaust. The difference between that ATC and the ESR powered ATC is unbelievable!
I'm currently waiting for my new 41.2mm PWK to arrive from ESR to go on the ESR 350. I can't wait to see how it runs with that carb compared to the 38!
Once you get it broke in and dialed in you won't be disappointed with your ESR350! :D
Tip: Make sure you re-check your cylinder and head nuts after a little bit of run time....

I have a 330 in a ATC its got alot of grunt. Dont use a Ricks electric CDI stick to OEM or the CR set up. I have a bent kicker and a ankle that still bothers me 3 years later for my foot slipping off.
-
^^^I second that!^^^
I made the mistake of running a Hot Shot CDI on my R. It used to kick back hard on warm engine re-starts..got much worse with the big bore, plus it broke up something fierce when trying to run high RPM, mimicking a jetting issue....
I went back to a good OEM CDI and it runs perfect now. Someday I would like to try a CR250 ignition.

I stand corrected. My jetting was 52 pilot DGH with 192 main. The 195 was a hair rich. But when your climbing the big dunes you had better be fat on the main. Back in the day I had a CT tip sheet that gave all jetting with different pipes. I believe it said to use the 192 for the big pipes

Wasn't trying to correct you Sir.. Just figured I would post up what my setup seemed to agree with. Hope you didn't take it that way..

Just the opposite, I don't want Pat using a main jet that will toast his piston. Some think a 182 is fat.... not even close. 190 is in the ball park but it has more to do with elevation. A 195 is needed if you ride like Pinned. But you can get away with a 192 if you blip the throttle alot!
-
hell yea guys this is great info!! thank you all for the suggestions!! i will use them all. also tony i installed that flywheel on yesterday. i started up the bike and while it was warming up started reving super fast so i shut it down. i think the base gasket blew. i have an air leak there. thats just my guess it seems like the gasket is all tore up. idk how since this is the area right under the pipe. nothing touches that area. im gona do a leak down test and replace that gasket. i have another one here. i may just leave the top end off since my 350 is coming next week.. woooohooooooo. hope your ready to ride tony!! is your family gona end up coming?? the more the better

Yes, I built a head board yesterday for their new to them 250r hauling trailer. Just 3 R's in our riding group and always an extra just in case. Maybee I will have to bring a second back up 408 Puma also seeing as one of you guys bikes will have some trouble. I know OJ is planning on the trip.
-
awesome!! and yea bring the puma!! would be awesome to see the power that thing makes

Pat got his 350 Friday morning and then drove to Windy Bay. Got him some o-rings by 10:30 Saturday as they had been misplaced a couple months ago. I can't believe you converted a stock sleeve spacer plate into a clearance for 350 sleeve by hand with a round file. Things that happen in the parking lot are always last resorts. When your 9 hours from home on the weekend ya gotta do what ya gotta do. If you were staying for the week I would have run back to the shop and get you a spacer plate and the collar that goes behind the front sprocket. I would also get my t-handle Allen wrenches and pull this smart carb apart to get it going again. That would have taken over 3 hours. Great to meet you Pat and would have been nice to do some group riding. We will catch ya next time.

yea would be awesome if we could have met up. wish my bike was working better for me. it was just problem after problem man. was so agravated!! the hand file on the spacer sure did take a lil bit and alot of work. did everything i could to get the bike to run. finally it was just getting way to hot i just shut her down. take it back to the garage and try it again tomorrow. when it was running though i could really feel the power and i was happy with what ive gotten so far. thanks for all of your help tony your an awesome guy!! i may need another spacer plate for the 350. would you happen to have one i could buy from ya. i can also paypal you some
more money on top of that for hooking me up with so many parts. got orings and gaskets on the way so should be good on that stuff..
-
Chainsaw file is good for more than just sharpening chains! :D I've used one more than a few times to make something work.
Glad to hear you like your 350 so far.... I'm guessing you had to run the spacer because you have the long rod setup???
Looking forward to hearing how you like it once you get it all dialed in and running good!
-
Wish I had been at home so I could have known about this, I might could have helped, sorry I wasnt.
Tonys right, sometime you got to do what you got to do.
Was a race a few years back at a national TT event, like normal for some, rider ended up the last minute getting his 4 poker engine put together & wouldnt you know it, NO valve reliefs in the top of that new piston, guess what he did.
Did what he had to do & some were walking past with looks on their face & mumbling under their breath watching him, that lasted until the checkers dropped & he waxed a bunch of their tails coming in 3rd in the Pro class & making the podioum pics. So, what ever it takes to get the job done, sometimes thats what you got to do.

lol.. yea i was out there doin all kinds of stuff to get this thing running.. this is i used the wrong sized spacer. if i would used the 5mm spacer i would have been good. i figured since there was a small lip in the dome for the head to sit in that the piston being so minimal above the deck of the cylinder it would work....... wroooong!! lol. ill figure it out though i catch on really quick. learning alot as i go. thanks for everybody's help!!
