Web cam question

[Tri-ZNate]

on the site there is the bolt in cam and thenn there is also underneath that a cam core, Performance Valve Spring Only, and you can buy the Performance Valve Spring Kit. now what is the cam core?

[willcamach]

i beleive you need to send them your old cam as the "cor" part. and they send you the upgraded cam

[Tri-ZNate]

i dunno, its $112 for the cam then $60 for the core if you want it.

The core charge is the money they want from you if you don't want to send them your old cam in exchange. If you send them your old cam they will inspect it to see if it can be rebuilt, if so, they will credit you the core charge. They will then rebuild the cam & sell it to someone else.
There are core charges on a lot of rebuildable items such as engine blocks, cylinder heads, starters, alternators, carbs, etc.

Oh ok thanks

Just so you know Webcam does not offer any "bolt in" cams. Any cam you get from them will require the hardend rockers too.

"Bolt in camshaft increases power throughout RPM range."

I only know what I read.

Well I'll tell you the rest of the story and you can do what you want with it. Webcam modifies cams via hard welding. They oversize then grind to spec. This is why they need your cam as a core. Hard welding makes a much stonger surface then your stock rockers. In very short order a webcam will eat at your rockers and ruin them. This is why they offer hard weld rockers. Hotcams and HRC cams are originals, no hard weld, they are drop in cams. The unfortunate thing is they don't have cams for the trikes.

Bottom line is if you put in a hard weld cam, you need to match the surface it will rub against. Other wise you'll just screw up your rockers and have to take it apart again.

thanks for the info.

is there a major advantage/power increse when one of these cams are installed. id like to squeeze a bit more performance out of my 200x but not willing to do so if im going to sacrifise reliability/engine life? or not see any real major gain in power.

Installing a Hi-Perf cam will simply move your powerband up the rpm range, less low end torque amd more high rpm power. Doing any modification will have it's trade offs. For instance, increasing compression gives you more power at all rpm's while causing more wear on starter gears, and increased engine temperature. A freeer flowing intake/exhaust system (when properly jetted), will increase power at the expense of more noise and possibly poorer water/dirt ingress. There is really no "free" ride. LOL LOL but hey, we're guys; we modify! Girls modify too, but mostly to Poodles and boobies !

Wow Rex, I got love for ya but this cam stuff is all wrong. You can get cams to make more power anywhere you want it. They don't shift the power, they make power. Now you can get a cam that just shifts but you don't nomaly see that. That's like saying a better flowing exhaust and intake will only shift power, it's just not true. In a nut shell a better cam opens your vavles more and for different durations so the cylinder can breath better.

Ok rex i agree with oldschoolin86 on this one. Lets take all other restrictions out of the question (carb etc) if you have your 250sx with a standard cam, replacing the cam with a performance one will add power right across the whole range of RPM's. Yes if your racing you will get cams that will make most of there power at the big numbers. but they will also make more power than stock low down. When you loook at buying a cam it will say, for low end power, high end etc. but this doesnt mean you lose low end power if you go for the cam !!! it will just make the most difference in power high in the rev range. Having a cam thats has a short duration and low lift will choke the engine. what you have said is that if a cam with a longer duration and higher lift is added it will only move where the power is.

[willcamach]

so what kind of gains should one expect when going from a stock cam to a mild or hotter cam. will it be like night and day. or just a subtle change in power?
