ESE's works engine tuner

[breezy]

morning, is there a specific/ rule of thumb, amount of degrees btdc that the pick up sensor should be positioned in relationship with the raised contact area on the outide of the rotor. this is stock 122 engine ignition.. it think there is info regarding something along these lines somewhere on here, but i cant find it..

sad to hear about Jonah Luma... my mom met him here ,in birmingham england , in a local gym she was a member of, said what a lovely bloke he was, "man mountain", she said!.... Great loss.

Luc Foekema ...facebook page is very good read plenty about 50cc engines.

shhh............. next you'll be telling everyone to check out the Free tech 50 pages from the UK and europe

ooops.... sorry

Cheers Teriks and TZ,

didn't have time yet to fully investigate, worked around it quit easily but the thing was more that the software pointed to the exhaust or carb and I am pretty sure that wasn't where the problem was. (though I'm sure I made some duff mistake somewhere)

Long story short, Neels is always watching Sent him the pack file and then we'll find out what is what.

Hi Breezy, thank you for your comments about Jonah.

On an Ignitech the base advance is measured from the heal of the raised contact area back to the trigger with the piston at TDC. The maximum gap is 30 deg, 20 is probably ideal.

Below are some links to posts about measuring and setting the base advance on an Ignitech ignition. Bucketracer's post has pictures and a video clip, it is well worth a look.

Unless you speak Chec, IgniTech can't realy help you with setup advice.

Once I got my head around the "Base Advance" bit shown in the pics below the rest was easy.

I got the job of setting up NedKellys IgniTech programmable Ignition. This is how we went about it with one of Team ESE's bikes and Mt Eden Motorcycles dyno.

Well in an attempt to get this thread back on track to two strokes, I've got a couple of questions that I am curious about with the NSR300s that we run.

Is running Ram air box a benefit to these bikes on NZ tracks? The reason I ask is there must be a point at which below that certain speed the ram air would have zero effect but at what speed does this become an advantage?

Also what effect does the ram air have on jetting. Is it required to run richer jetting to compensate for the ram air effect of do the carburettors sort themselves out.

For me it seems like a lot of extra complexity for potentially minimal gains, but I have no experience to know if it might be more than a minimal gain!

Anyway here is nice photo of the chambers that I'll hopefully be running for the Suzuki Series this year. We've had no end of problems with the stainless steel ones cracking so with a bit of luck the mild steel ones will be the good. I still plan on continuing with the hydroforming but between Work, Exams, Wedding and race season coming up there are just not enough hours in the day!

I ran ramair on my rgv in f3 an it only worked at puke in the last two gears didn't make any dif ference at any other track , I wouldn't do it again.

TeeZee, where did you found that loncin Ignition? And how much Power does it make when converted to 12Volt?
I have got a few motocross rotors in the shop and need a good stator.

cheers

Not sure how many Watts TZ gets but here is a link to where you can get Loncin race ignitions:- http://www.aliexpress.com/w/wholesale-stator-rotor.html and Ricky Stators is a good source for stators.

Thanks TZ350,i went for 20 degrees. Ive cobbled it together for my bantam project engine, had hoped to set up statically bang on first time, but i have a standard ignition curve graph so i can put a strobe on if it fires up to adjust it up as needs be.

Coo, can someone explain this from that site, . . it seems to have issues.

double ended with a different thread at each end. funny ad though.

[sonic_v]

I wonder what was causing the lack of speed in the Rygers at their recent kart testing session?

[Frits Overmars]

Neil, if I'm not mistaken you're playing with the Profi F2A engine that happened to cross my desk when Profi started producing our MB40 F3D engine.
I dug up some old files: 190° exhaust timing, 140° transfer timing and 0,14 cc combustion volume, does that sound about right?
I found a huge mismatch between blowdown angle.area (good for 26500 rpm) and transfer angle.area (good for 44000 rpm) but as Profi was happy with its performance, he decided not to change it, so all I did was calculate some pipes. If I remember correctly pipe #1 would be delivered with the engine while pipe #2 was experimental.
All pipe lengths are from the piston edge; all diameters are internal. Notice the narrow header and the 4,2 mm stinger diameter on #2?

Neil, I did some more digging and found experimental pipe #3. Forget about #2.

Things are happening behind the scenes as we speak...
Or that's the way I like to see it.
