I don't think that would be good enough as during heavy rain water will be getting to the air filter at all angles, you need a cover that goes completly around, I don't think you will be able to see the air filter much anyway since it will be covered by the fairing.
Got the handguards done now, there great, highly reccomended, or at least mod any none led ones,
Will get some pics during the daytime, got some night time ones not the best pics but you can get a idea of the brightness;

Looks awesome! Were they easy to mount?
Extremly easy, had them on, wired up & finished with in 10 minutes, took the wires down and into the back of the headlight bowl, undone the front of the bowl and pulled the wires through then connected them onto the ground & live of the low\main bulb.
Only nag was the cables dont come with any sleeving\wrap so i picked up 3metres of black on ebay for £3, slid that over the wires so its all water tight & tidy.
Finaly got a daytime shot;

Cheers, I'm glad my posts could be of some help. I also found the Haynes manual to be of great help (I learned most of the stuff I know from it), even though it doesn't cover any specific model of bike they are all built in a similar way and they often share the same engine so you can apply what's in the manual to almost any model of Chinese bike.
I have some upcoming posts on my ongoing projects which includes camshaft regrinding, modifying the stock exhaust at minimum cost and a custom digital instrument panel so stay tuned ;)
Digital display sounds good. I just got a top box so my next job is wiring up a break light into it.
Did you ever find an oil cooler to fit the k157fmi engine? im looking for one, because i dont like the heat coming off the engine in idle, after coming down from 73mph. also i cant seem to find a 16 or 17tooth front sprocket for the engine... although a few months ago i could. but now i have money theyre gone. I have a sinnis trackstar, so very similar bike.
If you really want an oil cooler you can do a custom job if you are good at diy (which is the cheaper option) or buy the complete kit from Taobao, the kit from China would be heavy and international postage is expensive so the whole lot would probably come to at least £100. I'll try and find the link for you.
As for the sprocket you can order the 17 tooth from taobao as well or get a 16 tooth locally, the 16 tooth is probably a better option.

Edit: Sorry I gave up on finding the oil cooler, Taobao is half broken at the moment.
Ok thanks very much for the link mate. (': nice work on your bike by the way. Looks nice, do you u still ride it? I also feel like at some point you said you were fitting a performance crankshaft. I might be wrong, but if you did, was they're any benefit? Or was it unnoticed but just better quality.
Thanks and yes I do still ride it. I don't think I mentioned a crankshaft but I did buy a performance camshaft which has been sitting in my "bike stuff" draw for about 9 months as I am too lazy to fit it.
hello spencer, i think i have read nearly all your posts upgrading your sinnis max, i am about to start adding some mods to my sinnis stealth (quingi qm125 2d) and would like your help and advice along with other, along the way as this is my first project, im new to engines and things, but i do do my own services and im very technical minded.
anyway my first 2 bits i want are an air filter and change my main jet, i know i need size 105, but am unsure which one would fit exactly, also the air filter im not sure if its 38mm or 42mm so again i am unsure which one exactly. i am going to use your half coke bottle idea,
but i was also thinking of removing the box but attaching the cone filter to the main rubber air pipe comeing from the carb,(sorry i dont know the technical name for said pipe,lol) rather than directly to the carb its self, this way the air filter would sit where the original air box was and would not need any water protection. along with this i would carve a nice shape in a perfect curved spot on my side fairing which would send air nearly directly to where the air filter would be, the new holes in fairing would be backed with metal mesh.
This is the main jet that you need:
http://www.ebay.co.uk/itm/Brass-main...item3f2c48e339
You need a 38mm air filter (I just measured to make sure).
You would still need water protection for your filter since rain will be able to get to it through the gap where the air filter box used to be, there are more elegant ways to waterproof it however:
http://www.ebay.co.uk/itm/38mm-SPLAS...item5d48392ff2
I like the idea of cutting holes in the fairings, I don't think it would increase performance but I would look cool.
cheers for the measyrment spencer, i will think about how i will do the air filter as i noticed today i will be unable to put the air filter straight to the carb as my fram will be in the way, i was reading you post on the problems you had with top end speed so i think i will try and look for a size 100 jet to install withe the airfilter instead of 105, and will install size 105 after iv put the exhaust on, im thinking of going for the lextek stainless steele performence exhaust,
If you are refering to the missfiring problems I was having before it was because I increased my main jet to a 120 or something after installing my big bore kit whereas it should be a 110 or 115. When I got my cone filter I had no other mods and I was using a 105 and it was fine. For a cone filter and exhaust a 107.5 or 110 main jet might be better.
I would be interested in hearing how well the lextek exhaust performs if you do decide to get one as I was thinking about buying one.
ahhh ok, iv ordered a 105 jet and a 38mm cone filter, i will be picking them up from bitzforbikes,co.uk store tomoro lunch time, so i will be installing both over weekend.
i think im settled on the lextek slip on pipe as its made by an alright company, and has been purposely designed for 125cc 4t road bikes, so i think i cant go wrong there, ill probably buy it in next 2 week, just looking for an full exhaust pipe now as i want a stainless Steele one to much, also im sure my standard exhaust has got some kind of air restriction in the pipe?? there is 2 welds ion pipe that make me think this, does yours have these welds??
now for your help, can you clarify for me the pipes coming from the airbox apart from the main one to the carb, i have 3 smaller pipes one comes out the bottom and seems to hold no purpose as it has a bung/cap at the end, the other 2 come out of the airbox next to the main carb pipe

you said that one is for the gases from pistons..... and the other is for exhaust emisions,... just wanyt to check my set up is the same as yours to not mess things up lol
thanks again
It looks very much like the 2 welds on your pipe is where the catalytic converter is placed. My exhaust is different to yours but I took mine apart and inside the down pipe there is another pipe which is slightly smaller which is prehaps some form of restriction but the real restriction is in the can / silencer; there are 2 plates inside with 1 small hole in each one (about 1 or 2 cm) for the exhaust gasses to squeese through, I would assume that your's is simula to this.
The pipes comming from the air box are for the SAI valve and the crank case breather, the SAI valve injects air in to the exhaust to burn off any unburnt fuel and thus reduce emmisions and the crank case breather exhausts combustion gasses that leak past the piston rings. You can simple tie off these tubes out of the way where rain is unlikely to get in to them and prehaps secure a piece of cloth over the end of each one as an air filter. The crank case breather only blows gasses out and the SAI valve does not suck air through anything critical (I think) so they do not need propper filtering.
I haven't done any interesting mods to my bike for a while so I thought that I'd make a powerful main beam headlight that doesn't melt everything around it or arc high voltage everywhere like my crappy HID bulbs did.
This headlight uses a 50W LED that I got from eBay for about £4, the great thing about LEDs is that they are way more efficient that standard filament bulbs (i.e. less waste heat and more light output) which means that a 50W LED outputs 10+ times more light than a filament bulb (I don't know the exact numbers). The light is focused with a lens which gives a focus cone of about 70 degrees. The LED requires about 33V to work so a boost converter is required to power it, I made one my self to save money but I think that they are fairly cheap to buy pre-made. I am running it at about 65W but I don't think that it will do much harm as long as it's cooled properly.
100W LEDs are roughly the same price but I have found that my alternator cannot keep up with that kind of power draw even at high RPMs so the battery goes dead.

The LED has to be cooled with a large heat sink since it outputs a fair amount of heat, I used an old CPU heat sink and it seems to do the job, I did not attach a fan as the air rushing around it while moving should be enough. I made a housing with some acrylic and lots of glue to make it as waterproof as possible. I haven't mounted it yet but I plan to put it on the front mud guard.
I haven't done much testing in the dark but it is very very bright; looking at it from any angle is blinding and the beam can make a dark piece of paper smoke at close range so I think that it will do well lighting up country roads, I just have to remember not to flash anyone or risk setting their eyes on fire.
This picture doesn't really do it much justice due to automatic light balance and stuff on my camera but note how the camera had to almost completely black out everything not in the light beam's path to keep the picture from being over exposed.

More pics to come once I stick it on my bike.
Hi Spencer. I know this is an old thread but is there any chance you can remember what air filter you had/have on your Sinnis max 2.
Cheers.
