HighLUX Posted October 8, 2018 Author Share Posted October 8, 2018 Fuck that Id die. Took it for a hoon up the road and almost stacked it leaning over and dragging the the peg/my steelcap gumboot. Quote Link to comment Share on other sites More sharing options...
HighLUX Posted October 9, 2018 Author Share Posted October 9, 2018 Went down the google rabbit hole on plug chops Getting close but would rather a bit rich for doing 600ks round the coast so swapped the 118 out for 122mj. Run out of daylight/fucks to do another plug chop but will try again tomorrow after work 4 1 Quote Link to comment Share on other sites More sharing options...
Raizer Posted October 9, 2018 Share Posted October 9, 2018 I see the confused reaction @AllTorque, guessing it's at the thread cut off? When doing a wide throttle test over only a short distance the plug won't fully colour up, the smoke ring tells the story better than the tip of the insulator but it's nearly impossible to see properly without cutting the threads off. 3 2 Quote Link to comment Share on other sites More sharing options...
AllTorque Posted October 9, 2018 Share Posted October 9, 2018 Oh, that makes sense. I was trying to figure out how it would spark without the earth. 2 Quote Link to comment Share on other sites More sharing options...

Popular Post HighLUX Posted October 16, 2018 Author Popular Post Share Posted October 16, 2018 Just got back from a succesful 80km test ride, other than almost doing a shakotom and ending up in the native down a bank all is sweet. Bit doughy with the 15t sprocket on but its happy sitting on 70-75kph at 8000rpm on the flat so that better than being tapped at 70kph doing 10000rpm. Still got a weird issue where it sometimes cuts out when you close the throttle at high speed but thinking its too rich on the pilot/idle circuit. Pulled the spanny off to give the head bolts another retorque now Iv done 150kms, piston and bore still look good through the exhaust port so im confident its not going to destroy itself like the first big block kit. 12 Quote Link to comment Share on other sites More sharing options...
Truenotch Posted October 17, 2018 Share Posted October 17, 2018 Good stuff! How many teeth was your original front sprocket and what's the rear? I've just ordered 3 sizes to play around with on my bike - I'll have 11T (standard), 12T, 13T and 14T sprockets to test. Quote Link to comment Share on other sites More sharing options...
HighLUX Posted October 18, 2018 Author Share Posted October 18, 2018 Standard front is 12t and havent counted the rear but its got lots of teeth dirtbike spec. Im hoping with a less rich tune and a tutu with squish it will improve the performance but that can wait til after east cape 1 Quote Link to comment Share on other sites More sharing options...
Truenotch Posted October 18, 2018 Share Posted October 18, 2018 Oh yep, that's roughly a 25% increase in ratio / reduction in torque. Mine will be 27% if I go to the 14T sprocket, but I ordered the smaller ones to get my acceleration back if it ends up too doughy . Quote Link to comment Share on other sites More sharing options...

Famous last words..... Was on my way 2 Ohope to kick off East Cape Ride when just before Edgecumbe it started to bog and die, clutched in and it stopped running. Whipped the exhaust off to be greeted with this sight again. (Interesting that it did almost 80kms of WOT before killing itself again which was the same kms it did when it killed the 1st BBK) AA roadside rescue/sharns thanks to @cletus and @RUNAMUCK got me to J5s place where I jumped on a loaner CT110 and delivered the post round the coast all weekend which was so sweet Whipped the head off at Johns to find a very chooched bore and piston plus a weird flame front burn mark on the combustion chamber, only getting complete burn on the front half of the head/same side as the exhaust port. 2T barry yarns have deducted that I cocked up the squish band when clearencing the head so the piston wouldnt hit it which is fucking with ignition turbulence so its not doing a complete burn- piston gets unevenly hot causing it to not be very round and digs itself into the bore causing the above. Cant do much except get myself in the dogbox by "spending more money on that bloody bike" so have a 3rd(and hopefully final) 70cc kit on the way from Germany plus found a 2nd hand un fucked with head in the UK which is also on its way via Youshop. Been going down the 2T rabbit hole on squish band setup so will actually measure it this time to get it right not just get a bit gungho on the dremel after a few Brianlownes and mexican cigarettes. In summary, 2 strokes are sweet when they are running but they dont like to run that much when I play with them 11 1 Quote Link to comment Share on other sites More sharing options...

HighLUX Posted December 6, 2018 Author Share Posted December 6, 2018 Acquiring a roll of solder to do your squish band measuring trick at this moment 2 Quote Link to comment Share on other sites More sharing options...
HighLUX Posted December 29, 2018 Author Share Posted December 29, 2018 Tutu’d with measuring the squish band then pussyed out on taking too much off the head so slapped it back together with 2 headgaskets and some copper spray so no clearance issues and half pie squish band. Removed the oiling barb from the head and jb welded the port up. Running good enough for me to nang round the farm/backroads for now. Might take it to the pakeha to get the squish band clearanced properly after the holidays 6 Quote Link to comment Share on other sites More sharing options...
flyingbrick Posted December 29, 2018 Share Posted December 29, 2018 Funny. My mb100 also has uneven squish (apparently, i too have uneven piston and had colouring) Bloody pita Quote Link to comment Share on other sites More sharing options...
kicker Posted December 30, 2018 Share Posted December 30, 2018 If taking to a fella get them to chuck a couple dowells in to locate the head concentrically on the cylinder, head bolts are a bit sloppy. 1 Quote Link to comment Share on other sites More sharing options...
HighLUX Posted December 30, 2018 Author Share Posted December 30, 2018 Yeah I noticed the head likes to move as you torque the studs up. Quote Link to comment Share on other sites More sharing options...

HighLUX Posted January 1, 2019 Author Share Posted January 1, 2019 Done 75ks in the last couple of days so whipped the head off to check out whats happening with compustion. As you can see its got the same issue of only burning on the front of the combustion chamber still with the new tutu'd with head. I thought the electrode for the plug being in the way was not helping the cause but they are 180 out on the 2 heads and still no difference. Time to get it booked in at @MopedNZ work the 2T wizards to sort it properly 2 Quote Link to comment Share on other sites More sharing options...
