So this injection system has a lambda and is going into the exhaust ,,,did it come with the pipe or do you have to mod an existing header tube? I have to mod the existing pipe. They include a bung.... I went ahead and ordered additional bungs because I'm going to go ahead and pull off all my exhaust pipes on all my scoots and install a bung on all of them. The Ecotrons stuff I have is two separate kits: ALM (Accurate Lambda Meter) is an air/fuel ratio (lambda) meter which uses Bosch LSU 4.9 wideband oxygen sensor and Bosch driver chip CJ125 to accurately measure the exhaust air/fuel ratio (AFR) of variant combustion engines. Small Engine Fuel Injection Kit – 35cc to 300cc Reason I'm isntalling bungs on all my scoots is so I can tune them with the ALM... You can use it to fine tune your scoot then uninstall it, cap off the bung and scoot about your merry way. ------------------------- I should have expanded a little more in my previous post... It's not just about getting her running perfect... Tuning these carbs is probably where I'm least experienced. No scoot mechanic is worthy of the wrench (errr actually, I should say screwdriver) he's using if he can't manage to tune a GY6 carb IMO... So, it's a learning curve for me also....Besides, I can pull a carb, rejet it and have it re-installed in about 5 minutes flat...I'm having fun doing it so I wouldn't call it a waste of time... I've found a few good sources like on totalruckus's GY6 swap section, but you would be surprised at the lack of information about 4 valve builds... Luckily, I have access to Taida's chief technician and that's who I have been going to for help. These forums are good for the noobs who have question like hey, wht type of CDI do I have... But when you're into the kind of builds that I'm doing, these forums aren't very good sources of info.... If I start a thread that says exclaims i'm building a 4 valver and the chain doesn't fit, It's very unlikely the thread will even get a response simply cause no one knows... Taida is like Lamborghini as to where Hoca and NCY types are like a camaro / firebird.... Taida products are what wins at the races and their engineers are helping me.  Why would I take that as a shot at me? I know sometimes people get into "pissing matches" on here and I even enjoy reading a good spirited debate, but on my end, I'm not about all that.... My purpose for participating in these forums is to learn and share what I have learned (and to meet new people, make some new friends)... While I have learned a lot, I still have a lot to go and never take good advice as a shot at me or in any other way than appreciative... I want to hear new ideas or if I'm wrong, be corrected... I appreciate your advice brother! We all have busy lives and your taking time out of yours to share what you know... It's appreciated! Yeah, I've got a few torque monsters on the bench right now.... This 155cc I just built was a last minute engine that I decided to build so I could get some experience before going on to my taida engines.... What I have on the bench right now: Another Taiwan Kit like this with the same type of 4 valve head, however the cylinder kit is a 63mm with a stroker of +3mm making for a 190cc. This is a rare a-case with the same style oil cooling as a b-case (oil ports on the crankcase)... I have 2, of the 180cc power kits that Partsforscooters sells (picked them up on sale) - These are 2 - valve B-case motors Then I have 2 Taida engines... Both are liquid and oil cooled, One is is a 191cc (63mm with a +3.5 stroker) and the other is the king of GY6's, it's a Taida 232cc.... 67mm piston with with +8.8mm crank... Both of these engines have custom made pistons to accommodate the stroke and both, are 4 valve... The 232cc will be the ultimate that can be done with a GY6 150cc... Man, this sure got long winded... Sorry for such a long post.... I feel like a wind up toy, you get me started talking and I just don't shut up  |

Man now i am really jealous!!! doesn't sound like you need the practice,,,,you can probably imagine what the big boy taida will produce,,,and also probably why your not seeing to much info on the 4 valve is that most people (not all) don't feel the need or have the extra resources to get into aggressive builds like you're doing,,,also some race teams/engine builders are tight lipped about the technical aspects of this kind of build and tuning,,,it's almost like a black art to them so most don't share the info and techniques they've learned over the course of years to get where they are,,it's really great of taida to let you have access to their tech staff,,,this is the sign of a very good company,,,now you've gone and done it tho,,,i have to do one

Yeah, the SMAX kit is sweet... I can convert it to a 180cc without having to cut the case, the big head and more aggressive cam for only $450.00... I was the first American to know about it... I have a working relationship not only with Taida's engineers, but I am also a VIP re-seller... I have access to all of Taida's products before they hit the general public.
If you're going to select Taida products for your build, I will get your foot in the door and give an intro to the sales staff... Don't order from the web, either order from me or if you're spending a min of $200, I can hook you up direct with my good friend Fanny Syong who is Taida's top US sales agent. She works at Taida HQ and will send parts direct and modify the parts to fit your build.
I finished uploading all my videos of the build of this 155cc... I'm just an amature at making these videos and haven't learned how to edit all that well ye so they're just hosted as filmed... But I think I got enough useful info here to make sure peolple find something useful...
It's a playlist of 8 videos....

I haven't cruised their whole site yet,,,I don't know if I would want to do a BB build on Chinese cases,,,I'll have to research it,,,you will be the first to know when I'm ready as I will source parts only from you,,, now I need to find a victim,,eeeerrr I mean bike I can work on with a decent chassis,,,probably be a sym or kymco ,,I'll see what presents itself,,,,oh and just by looking at what's entailed with this kind of build,,,I would think I'd be lucky to pull it off for a grand,,and knowing me it will take more than that to get it done

I kind of liken the GY6 to a 350 Chevy when it comes to parts to availability... What I mean by that is they're a dime a dozen and the parts are every where.... I know what it is you like about Kymco, I'm a big fan a Taiwan products too. Taida products are all Taiwan products... When I gave the Lambo/Camaro analogy, it even holds true on pricing. A Taida engine will set ya back some, sure, but if ya want the best, you have to pay for the best... Some of the great things about Taida, everything is top notch, Taiwan B-blocks with oil port in the r crankcase, all BBK's have option like ceramic coating, forging / high compression, strokers are balanced with their corresponding BBK's, TPI bearings, NJK seals, everything is top of the line Taiwan products... In my 232cc, nothing was made in China, not even my block. (Taida has their own blocks) ... You can not get more Taiwan than Taida. When the parts arrive, you can just tell how much higher the quality is... While they're not polished, they're nice and shiny and every part is engraved with the Taida and Taiwan lettering... The blocks come bare ... No bearings, bushings or seals... This is awesome if ya want to powder coat the engine..... ------------------------------ Another nice Taiwan Kit is 180cc Power kit the PFS sells... You need a donor motor but it's right around $450 and you can catch it on sale for cheaper... It's a decent kit... |

Just to chime in here. dmartin, you have done a great job both in your build and sharing your information. Even us old farts learn a thing or two. Keep it up Jim Thank you! I referenced your build you published as if it were a Chilton! Don't know if everyone else has seen it or not, but RapidJim also published a build ( right here's the link)..... It was my inspiration to actually build one of these motors... Without the thread you created, I may have been too hesitant because the lack of information out there.... So a big thanks goes out to you and all the guys like you who take the time to help other people!  |

Why would I take that as a shot at me?
