110 port job

[TheKeener]

OK im still gathering all the internals for my 110 im rebuilding. But i was wondering how much of a difference will it make to port my head. Iv got a 125 piston, performance intake, bigger carb, and a hotter cam. I was also wondering if there are any performance electrical parts out there that can help pep it up, and if there is are they worth it?

When you put hot parts in a motor with a stock or weak head you don't get what you should out of the motor. On the other hand when just port a head on an otherwise stock motor you don't usually get alot out of it, unless it's a particularly weak head. I've been porting heads for 30 years, that all I do, is headwork. Check my profile I've got some pics of some of my work there.

What are you calling portwork? Are you just talking of matchporting the intake to the head? Are you speaking of polishing the intake and exhaust after matchporting. Improper porting can make your trike run worse. In my opinion, for what you are doing to your trike, any real fancy porting will not help you at all. I really don't know what you consider high performance electrical components. I'm not even sure of what year 110 you are rebuilding? There is alot more to rebuilding an engine for performance than just throwing some parts at it. You have to make the parts work together harmoniously. The power is in all the little details. What frame are you running? Will you have fresh bearings in the front hub, the steering stem and the rear axle? How about a fresh chain? There's a reason that the whole system is referred to as the "power train". It all has to work together as smoothly as possible. A bad chain or bad bearings can rob you of alot of power. Also I didn't see you mention anything about an exhaust. Tires and sprocket ratios will affect how your engine runs as well. Are you building a torque producing engine or a top revving and speed engine? There are many factors to consider. What are your riding conditions? Best of luck with your build.

Its an 83 110, when im done everything is going to be new already got over half of my parts. Im trying to get the motor to be as powerful as possible and later when my buddy ,who builds his own custom Harleys, gets done with his latest chopper frame is going to build a fully suspended frame as i want a frame no one else has. I want the head ported and polished to achieve maximum flow. I just don't know if there is much that can be done with that little head, and 60 bucks is too much if im barley gong to gain anything but if the port job turns out like the one on my blaster it will defiantly help. The whole reason im building up the motor is because my buddy doesn't think it'll ever come close to keeping with a 185s plus i tend to go overboard on things. And im wondering if there are electrical components to produce a more powerful spark just for the hell of it. This is the smallest motor iv ever had so im not sure what gains to expect, id hook up co2 if it wouldn't blow the motor which im pretty sure it will

C02?????????????

Yeah... I hear they are filling bottles at the local Burger Kings now...

The cdi engines aren't the best to build. I would build up a 90. I would fix it up with a manual clutch and the hi/lo gear box delete. I would find a nice stroker crank and a big bore piston and the proper cylinder. Cam is up in the air depending on what compression you want to run and wether you want to run aftermaket gas or not or if you have the right piston and want to run alcohol. Once you figure these things out, they you can get a head ported to plaly with as it will make a bigger difference. Depending on your stroke and bore, then you can have around 183cc's or so, which would pretty much give your buddy a nasty shock. But to build a really really fast atc90 engine, you definitely shorten the engines life span considerably, and it's not cheap at all either. The 90 engine won't be a trail engine and it won't make alot of low end power depending on the cam. But part of the deal is, you have to find the parts. Some people have been buying and sitting on these parts for years. Personally, I have some neat stuff sitting on the shelf, but I'm not letting those parts go. Don't expect much from building your 110. Not trying to be mean, just letting you know the realilty since your parts choices were really limited back in the day, let alone now. Best of luck with your build.

c02 gives you an affect like nitrous, just less of a boom when you blow the head off the motor.

[Thorpe]

ya know C02 is used to extinguish fires right?

All i know i rode a 1990 blaster the guy had a bottle on. You hit the push button and it took off like crazy and he said it was co2? Don't think a two stroke could handle nos so not exactly sure what he filled it with.

[TheKeener]

So i called the guy and i was wrong it was propane with co2 mixed to tone it down he says? Rings get blown bout once a year tho.

Propane huh? I remember reading something about that for mountin sleds.

About the porting, if done right, it'll give you a percentage increase in torque and/or horsepower. BUT, a percentage of not much is barely anything at all...
