Upgrade carb for pulse adrenaline 125

**spencer2004** · 07-30-2012, 10:20 AM

Oh yeah I forgot about the battery, I just held mine in place with some zip ties and it sort of works. If the mounting holes on the new carb don't line up you can either drill new ones or widen them a bit with a small file. As for tuning I found a good guide for mikuni carbs but it should apply to the molkt carb aswell. http://walbro.com/brochurefiles/3368...g%20Manual.pdf

If you get it working right I'd love to know the results.

i checked and the batterys on its own mounting bracket so i can get rid of the airbox if needed but i would moust probarbly make a metal chamber around the filter to keep it dry , anyway the seller sent me a link to this one which is the same as the other but without the filter and it gives dimentions on the listing so i will go measure mine up later to see if its a straight swap , if it will be a lot of messing around to make it go on i wont buy it as it wont really be worth all the work http://www.ebay.co.uk/itm/1608535987...=p5197.c0.m619

Well first of all it's a good idea to order an extra set of gaskets and piston rings since they aren't sold anywhere else and if you do blow a gasket you would have to wait weeks for them to arrive from china, they can be found here and here.

Fitting it is fairly easy; I was able to fit it with almost no prior mechanical knowlage, it would help to buy the haynes manual for chinese 125cc motorcycles as it gives you a step by step guide on how to fit it. The only problem I ran in to was getting the cylinder head nuts off; due the fact that the nuts are pretty poor quality and I was using a crap socket set I stripped one of the nuts and had to hit it with a chizel for 3 hours until it came off. When fitting it make sure that you do everything correctly before moving on to the next step to save your self a load of hassle. Also be sure to run it in correctly.

After fitting my kit I didn't get much of a top speed gain until I fitted a 17 tooth front sprocket and I got a nice little gain after fitting a 28mm carb; I am using a 115 main jet and a 40 pilot jet by the way.

Feel free to ask me any questions if you aren't sure of something, I am usually able to answer pretty quickly.

Remove air filter box, replace with 38mm cone filter

Replace main jet in carb with a size 105

Aftermarket exhausts at a good price are hard to come by so you have to get creative with that one; modify your existing exhaust or have one from another bike welded on.
