    Exhaust system Problems

    I put everything back together on my bike (changed oil and put back in a known good jetting setup FCR MX 39) and the exhaust has some kind of problem now for sure...seems extremely hot at the baffle and restricted...the air doesn't seem to be flowing correctly I've taken the Spark Arrestor out and ran it without but same problem... its loud and strong and choppy...I had an exhaust leak and I used copper RTV to seal the slip joint from mid pipe to baffle a couple weeks ago...then I wrapped it in muffler foil tape and used a t bolt clamp to clamp around the slip joint...the exhaust fumes are terrible...Im carbon fowling plugs, pull the plug and its extremely covered in black soot...happened 3 times now...Im going to remove the entire system and check it out from head to baffle and re fit the entire thing...any idea what the hell this could be? the sound of bike is not smooth its a rough strong put put put noise...doesn't sound like it did before...Its a full yosh rs-2 purchased about 6 months ago...

    My bike only has about 3k miles on it...its a 2008 DRZ S. I've tested the engine and checked valves and seems the piston rings are holding pressure just fine...

    i am going to put some gas in the carb before putting it back in the bike and see if my shot is too early...I feel like it will hit the slide where its set but there is no play between the rod and the arm...the pump touches the diapphram and starts pumping the moment that throttle moves

    True that - I got to put the carb back in today and see what happens...I got the AP rod just barely touching the diaphram now so I think I got the shot close...I will let you know if I got it...

    I just tore the entire thing down to double check everything...carb is out of the bike and airboot and intake manifold all off the bike. Pulled the plug and its extremely carbon fowled??? I did add extra oil a few days ago - not that I had a leak but the dipstick was reading really low after warmup and I had to leave for work so I dumped some oil in there as better safe then sorry...i figured really ripping it and high rpm plus a lot of wheelies (just figured out how to wheelie recently) maybe i burned some oil.. Could over filling oil that fowl the plug? I took it for a spin before disassembling and the bike just has erratic idle. One min it starts surging and next minute its extremely low...I sprayed brake cleaner all over the intake boots and didn't find a definitive leak... Im really lost now but I have to get things back to where they were a few days ago... I did a leak down test and valve clearance check yesterday, cylinder holds pressure and barely any leakage register on my test gauges and valve clearance hasn't changed since last time I checked when i changed to e cams... Im going to drain and replace the oil (i don't have a new filter but i guess just drain both plugs and open oil filter area and get out what I can) Ill be putting back in the jetting i had prior to these issues as i know that ran well and what else can I do? I got the carb out so I will try to reset the AP timing with method people in this thread have suggested... going to lift subframe to re fit the carb...hoping this time i put it back together and it runs as it did before...

    Haha -- I don't think I can do that... I'm telling you for sure that EMN w 45 pilot and 160 main is way rich ...JD red needle is better but the FPro needle kicks ass of all that I've tried EMN, EMR, JD red & blue...way more snappy and responsive all around...JD Red I could barely power wheelie. I have everything exactly how i want it just the AP timing and pilot circuit got me confused... I feel like I can get the AP back to where it was but the pilot circuit is whats throwing me off..I never need choke to start and I never can get the bike to stall w fuel screw in...other than the pilot circuit my jetting is perfect for me. Even with the rich pilot circuit the bike runs incredibly well. Im just confused as to why I cannot get a pilot jet that I can use choke to cold start and make bike stall w fuel screw in...I just want to make changes to other jets in order to make the pilot circuit work w a 40 pilot. Im thinking the richness is from the needle diameter too rich, not the pilot...Thats how I came up with ideas like, I can try to put bigger pilot air jet w a pilot 40 or raise the float to accommodate for the rich diameter of needle. Also to use choke when cold start maybe I can change the starter jet?

    I think JD recommends 2.75mm baseline. I did change that to the 2.75mm baseline...3mm that I measured was too late of squirt and caused bike to stall...the 2.75mm causes the bikes idle to dip very low and if I am ripping the throttle and doing wheelies then come to a stop the idle also drops very low...around 11-1200, sometimes around 14-1500rpm

    Anyone here find the powerbowl useful for adjusting AP ? Just wondering if it would suit me as there are many people who have said it is great and others say totally not needed for TT fcr mx.. I really want to put the carb and jetting behind me at this point. i had my fun tinkering w the jets and no longer want to chase the ultimate jetting. I got some sm forks and triple clamp that are waiting to get installed next and the carb has taken me away from that project

    Yea i set it by measuring gap and it's off. Its causing my idle to dip really low if i crack the throttle slightly while stopped. Should i advance the squirt or delay it? I also checked it visually. Just missed the slide from what I can tell. Neverused to do this before I messedwith it t

    The intake bell was from the TT store kit...I have a spare E air intake boot and spare E airbox not in use...maybe I should look at getting a different bell mouth adapter like the E adapter or another bell mouth adapter, any suggestions...any suggestions? I took my carb out and cleaned it with compressed air and come carb cleaner solvent...38 pilot still didn't respond to fuel screw after cleaning...Im convinced I must have a leak somewhere thats causing these problems. The exhaust is sounding off again, like a Goped scooter not crisp or smooth like before...last time it did this the exhaust valve was tightening up and out of spec and has since been adjusted but I gotta check that again to see if it moved again. Also there was a leaking connection mid pipe to muffler connection that I sealed with rtv and exhaust tape...not sure what is going on now but I hope it is just an exhaust leak and a jetting issue because the bike is running like complete garbage all of the sudden... It is that the idle slows all of the sudden in lowers RPMS and it just stalls out if I don't keep the rpms up. Or all the sudden the bike is idling and it starts surging like 2-3k rpm while stopped... All of the sudden this started happening, seems like a leak somewhere just hope its not in the engine...

    Yes, I understand however the bike doesn't stall instead idle speed increases when the fuel screw is fully seated with bike at slowest idle possible..If I raise the float to 10mm it will lean everything out but especially in the lower throttle...Either that or try a 35 pilot and see if that will give me the correct reaction from fuel screw...or go with 40 pilot and a bigger pilot air? I come up with these ideas (thinking too much), then I put them in action and I don't get the result I was expecting...i understand what your saying but I'm not sure what to do if Im not getting that reaction... what would you do... A) Raise Float to 10mm b) Larger pilot air jet c) Smaller pilot fuel jet d) Run it rich and fuhhhgetta bout it I can't help but keep tinkering until I get it right, i try to stop and leave it alone but it draws me back in and here i am.. I really appreciate your help and taking the time to respond.

    Im thinking must be needle diameter causing this issue in the pilot...the needle is so much better all around then every other needle I've tried. If I get needle exact same everywhere else but with a little leaner diameter maybe that will help...going to try to get that today.

    Idle speed was too high - you're right I read this a couple of weeks ago and dialed it in with the slowest idle possible...even doing this the idle does not slow with fuel screw fully seated...any idea what else i can do? I did set the slow air back to 100 when I put in the 38 pilot...

    My engine is stock displacement. But I have e cams. AP shot is pretty much there now- no bog and pulls like a train w my jetting. I got it running nicely from bottom to top. The only thing is my pilot circuit. Switched to a 38 pilot and the slight bog in the closed to 1/4 throttle was gone but the fuel screw does not slow the idle when turned in!?!? I guess I am going to try a 35 pilot??? I dont know what else to do. I have an adjustable pilot air jet in the bellmouth -- maybe if I up the pilot air jet to a 150? I tried a 40 pilot w 125 pilot air and didnt help. Float level is dead on 9mm. Maybe I should up it to 10mm? Any thoughts??
