locogato11283 Posted July 12, 2004 Author Report Share Posted July 12, 2004 Where are your needle jets set? iffy as like it runs ok but not like when it it's the pipe? My shearer pipes are ok in the lower power rpm range, Lug to on the pipe than it is OH Shit Grin and SHIFT. It goes so fast threw the upper power band It's unreal. Mine still is peaky style powerband , COuld be my carbs or the Shearer pipes But i still have alot of tuning to do. SO time will tell. needle is right in the middle. im thinkin about takin it up one notch and see what happens. the top end is unreal, it pulls forever and i dont eve nhave my rocket pipes on it yet.

23champ Posted July 12, 2004 Report Share Posted July 12, 2004 loco, if your motor runs like mine,which I'm thinkin it does because we live about 15 miles away from each other, it pulls hard down low when you first nail it, then it acts like its to rich (has kind of a blubbering dead spot and doesn't really want to pull). This occurs right around 3/8 throttle or maybe a little before. Then by 1/2 throttle it has cleaned up and starts pulling hard again. I think the problem is on the slide cutaway. Im going to get 1 size leaner cut away on my slides and see if that cleans up the rich spot. By the way, I hope you blow Perrys ass away. He's been kinda doggin on my motor since i had it done.

Blue Duece Posted July 12, 2004 Report Share Posted July 12, 2004 im running pwk35's with 170 mains and 48 pilots. its got a toooon of top end, its great. from 1/8 till about 1/2 is iffy tho. i cant tell if its sposed to be like that or not. the power comes on at about 3/4 throttle and if i let off the power drops off. im sure the pilot is right on and so is the main. ive done plug checks and its perfect color. maybe i need to do something with the needles? any ideas? i really wasnt this thing runnin perfect. it is rediculous tho. i was runnin 13/41 gearing with some minor porting and it would take out in 3rd when i dumped it on dirt. now itll spin 4th with 14/41 gearing. its fuckin wild. but yea, any ideas on what to do with the midrange? when im draggin and i clutch it to shift, itll lose power. but when i dont clutch and just shift it hard, its fine. not sure about this. id try a 50 pilot, 170 main should be cool,i keep mine a pinch rich on the top end with 118 octane and 927, im running 34's i supose the 35's would be close, with delta 2's it should roll right on, off an idle, i presume your timing is advanced? 14/41 is geared fairly low for that motor, geared that low you should be able to do a slow roll in 2cnd and smack the throttle and loop it, im not savy on the rocket pipes, but jetted right you should have outstanding bottom end, its gonna haul big ass on top thats just a by product of a good port job, ive had a ton of CR-500's and i know you have one, thats how your shee should run now, just start getting squirly right when you punch it, rolling slow over whoops just snap it on and it lifts, just like the CR, no clutching, im geared 17/40 and mine will rattle your cheeks from 60-100mph, my needles are center position also with a single K&N, my plug chops look brown closer to black than tan and allways wet, i think the 118 burns a little different than the pump stuff, you should be running at least straight 108, i ride between 3500 and 1000 feet mostly, anywhere from 40-90 degrees......i think from what you describe it wants more fuel on the bottom, and then when your 170 kicks in off you go but im not a jetting guru, but jetted right i know it shouldnt have any flat spots, thats whats so cool about jims motor, its hard to do with dual carbs but try and pull your chokes (both if you can) and see if it gets snappy or falls on its face.....

Blue Duece Posted July 12, 2004 Report Share Posted July 12, 2004 (edited) thats funny you mentioned idle, did you put the smaller plot in to make it idle?, mine wont idle without taking up the slack in my throttle cable, but runs like shit without the 50 are you able to adjust your idles at the choke pull knob and raise and lower the idle? jim will tell you his motor aint known for its idling skills.......i still think you should try the 50 and see if it wakes up the bottom end.........ive been burried at work so i havnt been on as much Edited July 12, 2004 by Blue Duece Quote Link to comment Share on other sites More sharing options...

sredish Posted July 13, 2004 Report Share Posted July 13, 2004 so is it replacing the 500 as your new hillclimber? honestly, how would you compare the two motors now? Quote Link to comment Share on other sites More sharing options...
locogato11283 Posted July 13, 2004 Author Report Share Posted July 13, 2004 so is it replacing the 500 as your new hillclimber? honestly, how would you compare the two motors now? its not replacing, just joining. the cr500 is the reigning champion right now. we will see sunday how the new engine performs on a hill. before it was runnin 7.0's and the cr500 banshee was runnin 6.8's. surely with all this new shit itll be runnin at least 6.8's and hopefully faster. i really wanna drop down to 6.7's cuz it has never been done on a quad yet there. ill have videos to show my results Quote Link to comment Share on other sites More sharing options...
Blue Duece Posted July 13, 2004 Report Share Posted July 13, 2004 i tried the smaller plots and my bike cackled in the mids, so i went back to the fiftys, maybe its the 34's...that midrange snap is where all the balls are at in that engine though.....when im riding it a idle isnt my concern......

sredish Posted July 13, 2004 Report Share Posted July 13, 2004 the engine def pulls hard, the top is crazy. that's awesome. maybe we'll put it to the test when we hit LS. See how it compares to my fatties and lightened flywheel. Quote Link to comment Share on other sites More sharing options...

Justintoxicated Posted July 13, 2004 Report Share Posted July 13, 2004 (edited) I have Jim's 12-port which is different than his stroker, but I have PWK 33's and the 48 pilot idles fine, Starts on first kick...I had a 168 for the mains and it look like it was race jetted (White all the way down to bottem then a small brown ring. I put in some 172's and also bought some 170's jsut to be safe, if it does not bog thats where I'll leave it. But I didn't make the Glamis trip last weekend because the guy I was supposed to meet up with shot himself with a nailgun or someing So I have not had a chance to test it out. I also have more restrictive pipes... I love jetting these carbs with clamp ons, 100x easier than with my stock carbs TORS and the airbox! Supposed to go to Corral Canyon this weekend and the alt is around 3000 feet higher, so I'll probably end up re-jetting again. And switching my tires back....What a fucking waste of time!
