JK1 Posted July 13, 2015 Author Posted July 13, 2015 (edited) The first start of this summer is near! We tried it yesterday, but had a few problems: A couple of the relays had a bad wiring, oil cooler hose was leaking, the injectors work in wrong order... Maybe today! The bike is still missing the wiring for the tacho, warning lights and headlight. The wiring (done properly) takes A LOT of time!J Edited July 13, 2015 by JK1 grammar 1 Quote
JK1 Posted July 13, 2015 Author Posted July 13, 2015 (edited) Success!! A couple of coil connectors were crossed, after fixing that the bike is alive! The engine sounds nice (loud).The fuel is going through the system fast, with a few litres the bike runs about 20 sec. Because of the temporary tank the return line goes to a different can.

spondonturbo Posted July 14, 2015 Posted July 14, 2015 a lot of work gone in to that. looks a lot better now. That tubular arm looks like it needs a lot more adding. keep posting pics please Quote
JK1 Posted July 15, 2015 Author Posted July 15, 2015 We took the wiring harness out for the final fixing. Fuse box, coils, map etc. Basically wiring for the lights and turn signals. Still missing this:This is the wiring harness for the ecu, sensors, coils, injectors etc. J Quote
RojoMojo Posted July 16, 2015 Posted July 16, 2015 As a newbie i am humbled and in awe of the sheer talent a lot of people on this site have. Following this with great interest. 1 Quote
kenty Posted July 16, 2015 Posted July 16, 2015 ive kept out of this section because of stuff like this ....... too much information is a bad thing it can lead to all sorts of ideas forming ..... good skills going on here ,keep the pics and information coming @JK1 , this is going to be worth all the trouble when you get it finished .. ill keep an eye on the build . 2 Quote
KATANAMANGLER Posted July 17, 2015 Posted July 17, 2015 This is definitely a build that is taking the road less travelled. Good to see someone not afraid to make it up as they go along. 1 Quote
snoorder Posted July 17, 2015 Posted July 17, 2015 Seriously cool project! Respect for all the skills! 1 Quote
JK1 Posted July 19, 2015 Author Posted July 19, 2015 (edited) First ride!!! I rode the bike a couple of times around the garage!!The bike has 2 Lifepo4- batteries which work extremely well! Lets see how long The other got a little damaged, maybe too quick discharging.. But its still working. J Edited July 19, 2015 by JK1 correct link Quote
Gixer1460 Posted July 19, 2015 Posted July 19, 2015 why's the lambda guage freaking out like that? Quote
JK1 Posted July 19, 2015 Author Posted July 19, 2015 why's the lambda guage freaking out like that?The phone´s camera f**k´s it up, I guess ?!? It looked fine to me IRL, but I´ll have to check that.J Quote
JK1 Posted July 20, 2015 Author Posted July 20, 2015 Now the fun starts... NOT. A/F ratio is going from lean to rich and back lean. Tuning the fuel chart seems to do nothing... The spark plugs look all the same (dark brown, rich I know). I took a 10km ride, worked ok while rpm was over 3k. The boost climbed to 0,7bar (10psi), then the mixture went rich (wot). After backing up the throttle, it was a little better. Idle is high or nothing There has to be some technical/electrical issue thats causing the problems. I´ll have to try with a new set of plugs first.J Quote
E10 Posted July 22, 2015 Posted July 22, 2015 To bad this kind of troubles.. its sems nixe on the film start... was waiting for some revs.. Quote
JK1 Posted July 24, 2015 Author Posted July 24, 2015 (edited) The engine is getting too much fuel from idle to wot... I got the idle tuned, but now its still getting too rich when I turn the throttle. I need to get it on dyno... Took a 100km trip today....+ The bike got me there and back+ It´s ok to ride+ speedo works and is accurate+ the LiFePo4 batteries work- LOUD- Gets hot in the traffic as someone suspected - Clutch slipping --> fixed (I hope) slave/master cylinder problem- Seat is too hard for longer trips- Fuel tank has a few pinholes in the weld- Oil leak, sump - Cam sensor wire almost broken- Suspension is too hard, need to adjust that.- Rest of the warning lights need to be programmed to ecu/tacho J Edited July 25, 2015 by JK1 More stuff 3 Quote
JK1 Posted August 4, 2015 Author Posted August 4, 2015 (edited) Sun is shining! What a rare thing this summer...With a little changes to the fuel chart, the bike works better and better. I booked some dyno time for next week, I`m really looking forward to that. Maybe not the peak hp, but to get the bike working smoothly.I´m not sure if my lambda placement is messing up the reading for the meter. The lambda for the ecu seems to work ok. Here´s the only picture I have at the moment. The bike has 2 lambdas, one for the meter/rider, and one for the ecu.They are one after another, maybe that creates some kind of magical exhaust flow. J Edited August 4, 2015 by JK1 details Quote
JK1 Posted August 12, 2015 Author Posted August 12, 2015 (edited) The trip to the dyno went ok, the bike is still in one piece. The tuning took 6 hours, but the bike is still not running 100% . It*s either the ignition/plugs or the intake boots(?) are faulty/leaking, After reaching 7000rpm the AFR is getting way lean. The boots don´t look too good, and the intake plenum straps may cause the plenum to move up at higher boost--> intake leak.. J Edited August 12, 2015 by JK1 grammar Quote
Fula28 Posted August 12, 2015 Posted August 12, 2015 Progress jk1 , it maybe small but your nearly there! Sounding pretty good so far. Quote
slingy1157 Posted August 13, 2015 Posted August 13, 2015 (edited) Hi JK1, been following your build. Like it alot. Are you sure it's not the fuel pump not keeping up? Or a restriction in the fuel circuit somewhere. If you keep adding injector opening time but have no gain in afr, it sounds like fuel pressure or flow isn't enough. If it's only doing it above 7k when boosting, then as everything on the intake side is under pressure, if it was leaking, this will result in a drop of boost pressure and thus for a given amount of fuel, it should go richer. but all depends a bit how your fueling is set up to work. Anyway, nearly there keep at it. Edited August 13, 2015 by slingy1157 Quote
Leblowski Posted August 13, 2015 Posted August 13, 2015 What kind off injectors you are running ?? and whats the dutycycle of them while running lean ?? Quote
Gixer1460 Posted August 13, 2015 Posted August 13, 2015 Lambda sensor placement is critical when using a dump pipe! When flow is low it will be fooled by atmospheric air so indicating lean condition.I've got my ecu sensor at the collector pre turbo - against all the advise mind you but if the back pressure kills it after a few '000's miles its not the end of the worldto replace with a new one + its more accurate as direct from cylinders not with added turbo oil ! ! ! Quote
JK1 Posted August 13, 2015 Author Posted August 13, 2015 Thanks guys! The injectors are 1000cc low resistance.. I didn´t pay too much attention to the dutycycle, I´m a real novice with this. The guy at the dyno is one of the best in Finland, so I´m trusting him knowing his stuff.The fuel pump should be enough, the same pump has been used in a 400hp Busa, but I´ll have to check that. The fuel pressure is even 3bar, don´t know about the flow.The lambda sensor for the ecu was giving the same reading as the one in the dyno, and now after the tuning the sensor for the gauge is giving sensible readings.J Quote
