UTERUS Posted November 8, 2019 Share Posted November 8, 2019 I found that as long as you were up in rpm that you could check part throttle afr without reversion issues. Quote Link to comment Share on other sites More sharing options...

Yeah i guess part throttle low RPM doesnt really need dialing in on a GN since; 1) Its not fuel injected. 2) It wont be moving. Quote Link to comment Share on other sites More sharing options...

tortron Posted November 16, 2019 Author Share Posted November 16, 2019 So en150s run the same carb and a 115 main jet I could have sworn I saw 115 on the GN manual, but it's a 110 on second look and on opening it up it's a 110 Big hill must have been just enough to lean it out Have some jets. Will have to try a 120 as I got sent two 105s and no 115s Will check with O2 sensor and can move the needle between 3 notches. See how she goes Quote Link to comment Share on other sites More sharing options...

tortron Posted November 16, 2019 Author Share Posted November 16, 2019 So New "genuine" rings in. Looks better than the last set. One was near touching in the bore so filed it open a bit. No data on that in the manual but around 0.2 mm was the maths. Max gap is 0.5mm in the manual 120# main jet in As suspected its rich. About 12.9-13.2 at idle. About that again at very part throttle High rpm cruise about 11.4 WOT 10.2-10.9 So a #115 is likely the correct one 4 Quote Link to comment Share on other sites More sharing options...
tortron Posted November 17, 2019 Author Share Posted November 17, 2019 I scrounged up a #115 jet and went for a tootle around the back roads of East South Auckland. It's an improvement. It's now on the rich side of a good tune throughout the throttle range. Splitting the difference at #112.5 if there is such a thing may be spot on till I get some altitude under me I guess. It is kinda warm today though too. Am I going to become one of those 2 lane blacktop guys, probably not, but the wideband can stay in for a while and the jets can stay in my pocket. So far so good 7 Quote Link to comment Share on other sites More sharing options...

tortron Posted November 17, 2019 Author Share Posted November 17, 2019 It has some more go in the 5-8000rpm range which makes the slow winding roads a bit more fun 1 Quote Link to comment Share on other sites More sharing options...
Popular Post tortron Posted November 17, 2019 Author Popular Post Share Posted November 17, 2019 Put together an extensive tool kit Not quite enough to fully strip the bike and engine, but close enough. And then I figured I may as well make a larger foot for the side stand. It sunk a little in the Motu river bed, probably not a big issue really, but here it is. As big as you can go without modding anything else. 12 Quote Link to comment Share on other sites More sharing options...
Popular Post tortron Posted December 2, 2019 Author Popular Post Share Posted December 2, 2019 Post eastcape thoughts 150cc kit was pretty nice to have. Just leave it in 3rd gear and use it like a twist and go. Top comfortable speed with loaded panniers is about 90kph. Handling on gravel is noticeably wobblier with panniers on the back. Rear tyre is ok. I would quite like a more aggressive/adv tread for gravel. Not desperate but would be an improvement. Leaving Auckland I lost power for a second on the Bombay's and thought I'd cooked it in the same spot it died last time. Carried on and found it was stumbling at over 8k rpm under a good load. Didn't notice this the week previous but I was going easy on it and had no extra weight. Plug looked like it had some brown spots in it (but was the oil contaminated one from the last rings) as a precaution I bunged in a cooler plug and started using 95 octane fuel. The stumble went away except for a small one very rarely at just under wot under load. I tried 91 again leaving opotiki and the stumble came back. Filled with 95 again and it's gone. So I'm thinking the increased compression from the kit is the cause. Cooler plug looks fine but will try again with a fresh standard. Should add that I never gapped the cooler plug so that may explain the infrequent stumble, wideband shows a bump in richness so I'm thinking the spark is the issue. Riding it today with no weight on it it doesn't happen and bangs out to 110 happily. Current jetting is standard main jet (110) and needle lifted from middle to top. This is the same as it was when the rings went, but wideband says rich and 1000km of loaded riding says it's ok. Guessing garbage rings. Mix is ok at idle and wot. Everything else is rich (high 10s to high 11s). Going to need to fiddle with the emulsion tube I think. Have ordered a new standard one from Ali. Will try that to see how different it is from the original and then start drilling. Exhaust header appears to be two layers so it's smaller than it looks. I'm thinking a new one that's actual size will help the top end. Usb in bike is lush for camp site phone charging. Led bar is lush for when headlight bulb shakes itself off. Stuff for next time? I think I could use some even smaller panniers to carry my "sleep system" which weighs like 1kg all up. If staying at similar places I won't need the stove, just need a zip/kettle at campgrounds. Will take a tarp next time, never got around to getting one this year. Bivy is great no moisture inside but would be miserable getting into in a hail storm, plenty of building at campgrounds to shelter under though Possibly don't need to take a puncture kit. If I don't take that then there's no reason to take levers. Tyres are good cond, just don't be unlucky. Don't need a fuel bottle, always had enough to get to the next pump if I couldn't fill at the nearest one for some reason. Wasn't sure on economy with the 150 kit and loaded, but it's only slight more than before. Potentially shift some weight further forward. I think this would improve gravel handling. I sold my tank bag just before I got the bike - because I won't be needing this for a while.... A pace notes holder would be an ideal addition. Anyway. Got home, changed the oil. It's looking perfect. Oiled the squeaky chain, back into commuting duty 21 3 Quote Link to comment Share on other sites More sharing options...

tortron Posted December 6, 2019 Author Share Posted December 6, 2019 Sorted the DR200 header pipe to fit. Flange end needed to be sanded down about 1mm dia. Have to remove tool box from GN. But otherwise it goes on with no issues. Would recommend offsetting the regulator a bit to avoid the heat and perhaps some reflective foil under the battery box. Header pipe ends just under the battery. Not sure what to do about a muffler and how to route it where it's not going to be in the way of panniers/pillions. May have to just make one up to fit in the allocated spot I suspect it will free up some power. The standard pipe appears to be dual layer from the head to the muffler so is smaller than it looks. For noise maybe? 2 Quote Link to comment Share on other sites More sharing options...

tortron Posted December 7, 2019 Author Share Posted December 7, 2019 "Can't" find decent adventure tyres for a 16" rim Looked at a new spoke rear but kinda expensive with postage. Suzuki parts bin comes through I picked up a front and rear gt200 wheel. Both are 18" as was the style of the day, both kinda narrow, but I think I can run a 3.00 tyre on the rear no issues. Some of those cafe racer GN things are running 4.00s but I don't see anyone commenting on how they ride. They don't go fast enough to be an issue I guess. Should look better with something bigger than the pizza cutter on the rear now. Rim is narrower than I would like, but such is the budget Will probably go with a shinko rear, I don't see any heidenaus in the right size any more. Will see how the gearing goes, I was considering a new sprocket, this should gear it up a bit. Probably ok with just me on it, maybe not ok with it heavy. 7 Quote Link to comment Share on other sites More sharing options...
TimShadboltfan27 Posted December 7, 2019 Share Posted December 7, 2019 Throwing star Suzuki rims are amazing. Makes it look like a baby GS! i can fit a 3.00 on the rear of rx125 for reference, or maybe for a /ling Quote Link to comment Share on other sites More sharing options...
