Well I have done it took the lc2 to projex and put it on the dyno to sort it out once and for all....1st comment when I was telling him what was wrong it it should not have any flat spots so he went and checked the power value and we found the bloody pulley had broken...however they are great chaps and glued the ting together for me which held out very well so dyno time was back on. ( I had rode 90mls for this!) Now into the detail......bike is standard k31 motor standard cdi etc banshee coils, yam racing reads, airbox snorkels removed and dry filter, 280 main jets 25 pilot and needle on standard clip position and (tsa) kennys pipes road spec. Did try on down but caused missing etc....here is the results.. Basically it's making 65.47bhp at 9960 revs and 35ftllb torque at 8500k........ Obviously really happy and now the pv is actually working correctly it flys.....this results says it all about kennys pipes

that is a really good result, but it is running weak lift the needle a notch to be safe

that is a really good result, but it is running weak lift the needle a notch to be safe View on the dyno was that it was actually running a little rich on the needle and I dropped it one notch but it messed up the midrange. Assume you mean the 5k ish point? See what you mean......will give it a try and see what it does . It's nice when you know exactly where you are starting from.

I would go up one size on the mains to be safe the afr is not perfect for setting a 2 stroke but better than nothing. I aim for 12-12.5 minimun when I do mine. It may knock off 2 bhp off the top but much safer. Best thing is there is more to come if you fitted a zeeltronic kit maybe 68+bhp is on the cards which isnt bad from a std engine mate nice work.

The lower limit in the graph is 12.5the upper line 13.5 and results appear to be generally 13 apart from that spike at 5 ish which it dips down to abut 12.25 do you still think I need to up the main a bit? The zeeltronic I assume would need setting up etc not just a bolt on and ride?

good result, did you do a cruise test as that is probably more important than a full throttle test which only gives you max BHP etc, it does show your fueling generally, but a cruise test shows exactly what is going on at the rev's you spend most of your time at
You probably would benefit from going up one on the main and accept losing a couple of horses off the top end to richen that mid range up, not sure you would get that on the needle if I am honest, as Kenny has pointed out, on a cool autumn or spring day you will be running even weaker if you don't richen it up, which could end up with a hole in a place you could do without ±

He was cruising the motor alot at 5 to 6k because of the slight missing but did not print any graphs however I think the graph shows how it runs a little weak then to rich...on the road all the previous issues has gone at it cruises great at all revs and even pulls top from 5k....this was the pv pulley issue all the time.... Was a great ride home different bike violent power from 6.5 k right to the red line and with the mid and bottom power back it does go well very fast pick up .... Will do as suggested and go up on main hopefully it won't mess the mid up.....5 to 6k is the trouble spot on bike...I was told that a programable CID would help as it may just need advancing or retarding at that point to smooth out...but decided not go that route expense and more hassle......I now want o just ride and enjoy... One thing I would add before I removed the snorkels in the airbox and dried filter I was running 260's with needle dropped one...bet it was a bit week in mid...think I have been lucky with this.. Also appears is fuelling spot on exactly the same on both cylinders....

its a good result nonetheless, yes, get out ands ride it, it should be a lovely thing to ride as the power curve looks very good.
Looks like my posting all that time back about the snorkel has paid dividends for lots of people, makes all the effort and expense of all that dyno time worthwhile when you see results like this, I did another last week, removd the snorkel, re-jetted and it went from 44.5bhp to 50.2bhp, the owner was a very happy chappy when he got it back !

Well back from the dyno and got a best of 67.91bhp at 10,184 let's call it 68 LOL But for those few extra ponies that was a Mick Abbey tune,PWKs,Zeel PV controller (although I didn't adjust it there) it's questionable to go further ? Full Zeel could hit 70 plus but I was running rich on the main (152) and coming down to 150 may have got 1 or 2 BHP more ? But in hindsight I would just say just get a Mick Abbey fast road tune and some Kenny TSA pipes, maybe Vforce reed blocks Wow 68hp. Did you compare the graph with mine by any chance just wondered if you were gaining across the range or just the top end? .just changed jets tonight from 280 to 290 as suggested above yet to see the effect on the road just hope my midrange issue does not come back if it does (think its that real rich spot in the graph) i am going to drop the needle one notch. I guess I would be correct in stating that it would still be running richer that my base dyno test .....overall I hope that it run fine with the 290 s and current standard clip position..

Well you can't knock 68 hp mine is probably now down to about 63 after jetting up so really that's the comparison for both bikes running safe.

Do projex have a selection of main jets available to swap in when on the dyno?

Naff all in it our kid it just nipped the last few ponies at the top,that's all They wanted me to have a fiddle altering the powervalve openings to see if the midrange plumped up but I said another day LOL Jetting down a size and doing the zeel PV box would have probably fine tuned it but I was resting on my laurels LOL That's a really good result with a 31k cdi, a full zeel would get you another few ponies with a little more advance. Know what you mean with questioning doing more, would be good to get mine on the same dyno for direct comparison. Need to get mine re done now the latest mods are done. What torque figure did you get? Makes me wonder if I went over the top Steve

35 ft pounds pretty much from 7000rpm to peak Kenny uses this dyno too That's a nice figure. Think that's where mine benefits most from the extra stroke, makes 35 at 7000 rising to 41 at 9-9400 Would be good to get down but it is a long way down, need to get it checked. Still really impressed by 65 out a standard motor wow Steve

I reckon it will be standard give or take, I've set 2 powervalves (31k's) up over the last month or so, both in standard trim including standard exhausts and after setting them up on the dyno, both made just over 50bhp each, so a set of kenny's pipes and a few tweaks could see 60+bhp without too much trouble.
The results and tests I have done on the exhausts etc I am still sorting out, but one detail I will release now is that Kenny's pipes made 9bhp more than a stock set of LC pipes and that was without any jetting or fiddling to make the bike/carburation run as good as it could, and it was running rich, so I can well beleive the numbers above.
Did you get any acceleration graphs from them?, these are the more telling of the graphs to be honest, max BHP isn't the whole story

oh yes, it makes for interesting reading when you compare them, especially like the ones I have for each exhaust I tested, it tells a tale of 2 stories, big horse power doesn't always equal best pipe !! - but that would be telling now wouldn't it !!

Just for info mine made 35ftlb at 8470 revs It's not just the peak that is good, you have a nice flat torque curve from 7k which is nice. As has been said top end hp is one thing but you need good torque. Good example of this is petrol and turbo diesel cars. a 1.6 petrol and a 1.6 TD will both make around 110 hp but the diesel will trounce it every time, will have more grunt and be more drivable.

yup, and that's what the acceleration graphs show in stark detail, how the torque comes into its own over bhp.
