kw04 Posted December 12, 2004 Report Posted December 12, 2004 i just put a stroker in and i was wondering whats a good starting point for the jetting it has stock carbs with toomey throttle cabbles and k&n pods tep is around 50 deg down here Quote
sredish Posted December 12, 2004 Report Posted December 12, 2004 Whatever you do, don't ask locogato, those Missouri boys can't jet for shit.... j/k bro. Hey, I'm gonna take a wild guess here. I have no experience jetting strokers and big bores, but I'm gonna say try some 380s to 400s in the main. I could be totally wrong, but I feel thats where I'd start if it were my machine. Also, it might be time to invest in some bigger carbs to really get the full potential. Later. Quote
Banchetta Posted December 17, 2004 Report Posted December 17, 2004 Start w/ 380 mains, stock pilots, needles 2nd-3rd clip from the blunt end. This is just a starting point, but will get you close...I ran 370's in mine last spring on the dyno around that temp. Let us know what you end up w/...Sredish is right. You should get some 35's, strokers love to breath. Quote
fixitrod Posted December 17, 2004 Report Posted December 17, 2004 I have to agree. 380's to 400's depending on humidity, elevation and temp. You really need some bigger carbs for the motor. You will gain bottom to top. Quote
kw04 Posted December 17, 2004 Author Report Posted December 17, 2004 i have 260 mains in it right now i think it get enough fuel because when it does run it hauls ass. the guy i had build it says it might be the stator. he thinks when it gets hot it stops working right. he is checking my electrical system right now. when i figure it out i will let you guys know but if you have any other suggestions please let me know. what do you think about 34mm pj's Quote
00BANSHEE Posted December 17, 2004 Report Posted December 17, 2004 Get you a pair of pwk 35mm carbs. They are easier to jet then the PJs. You are way to lean running 260 mains in the stock carbs if you have aftermarket pipes. You really haven't told us much about you setup. Quote
kw04 Posted December 17, 2004 Author Report Posted December 17, 2004 heres what i have 400 stroker ported & polished cool head w/22cc domes 3/8 reed spacer v force reeds k&n pods adjustable timing plate advanced 3deg fmf fatty's hinson clutch basket dirt digger clutch toomey throttle cables thats all for right now i need to also get a suspension and probably carbs to big time.

Wallrat Posted December 17, 2004 Report Posted December 17, 2004 Ya your ridiculously lean man. Remember...start rich and work your way down. I think I've got 270's in my bike and all I have is pipes and a filter. At least I think I have 270s...damn been so long since I rode anywhere but glamis that I haven't jetted in like a year! Quote
kw04 Posted December 18, 2004 Author Report Posted December 18, 2004 (edited) see i dont understand because people keep telling me oh just jet like it was just the pipes on there then other people tell me to go bigger on the jets so i think i just might go bigger on the jets. what about the stator assemble because when it stops running on one side or the other it seems like it isint getting spark but it does. but them the engine builder said it could get hot then stop working so im just a tad bit stumped Edited December 18, 2004 by kw04 Quote

That is why these guys are telling you to go bigger. Here is some very useful info I got from someone on this site. http://www.dfn.com/benkaren/jetfaq.html If you read this you will be an expert.

Bensshee Posted December 18, 2004 Report Posted December 18, 2004 That motor needs the fuel, trust banchetta and fixitrod. Fuel is cheap, jets are cheap rebuilding the shee after being extremely lean can get expensive. Quote
kw04 Posted December 18, 2004 Author Report Posted December 18, 2004 thanks for the info but what about the stator do you think that could have anything to do with it Quote
Redlined Posted December 18, 2004 Report Posted December 18, 2004 It could. But I would play with the jetting first. Quote
Wallrat Posted December 18, 2004 Report Posted December 18, 2004 (edited) Ya given that everyone here says your way too lean, focus on that first. If it still runs bad then come back to us and we'll work on the next problem. I doubt its your stator though. Jetting for just pipes is nutty cuz porting/polishing is gonna cause you to have WAY more airflow. Just a guess here but you've probably already done some damage since it sounds like you've been running it alot the way it is. The reason why you always start rich and work your way down is cuz running just long enough to wind it out and get a good read from the plugs is plenty of time to cause some serious damage. I'd check your compression, fire your builder, and get some 380's - 400's. Edited December 18, 2004 by Wallrat Quote
kw04 Posted December 19, 2004 Author Report Posted December 19, 2004 i have only ridden it 2 times since it was built both times it was no more than 15 min but i will heck the compression and then rejet it most definetly. stupid question what do you think the compression should be around? Quote
