Webcam welds used camshafts to build up the material, then grinds then down to new lobe profiles and overlaps.
You'll pay $131 for welding a regrinding a cam. That is a service, not a part.
There are a few options of the source of the cam that is welded and reground for you:
1) You pay $121 for a used cam that Webcam welds and regrinds for you. This $121 core charge is in addition to the $131 charge for the welding and regrinding. Webcam ships the reworked cam to you. You pay $252 for your new cam.
2) You pay $121 for a used cam that Webcam welds and regrinds for you. This $121 core charge is in addition to the $131 charge for the welding and regrinding. Webcam ships the reworked cam to you. When you ship your original cam to Webcam, and IF it passes inspection as good enough to be welded and reground, Webcam will refund your $121 core charge. If the cam cannot be welded and reused, you are out the $121. This way you have minimal down time, but you risk the $121. You could pay $131 for your new cam or $252.
3) You pay for a used cam and ship it to Webcam. There are a number of models that can be sent in, XT225, TT-R230, some 4-wheelers, etc. Webcam welds and regrinds for you for $131 charge for the welding and regrinding. Webcam ships the reworked cam to you. This way you have minimal down time and your new cam costs whatever you paid for it plus $131.
4) You buy a new replacement cam for ~$90 and have it shipped to Webcam. You pay Webcam $131 to weld and regrind that new cam. No down time, but you pay $221 for your cam.
5) You pull your cam and send it to Webcam. The inspect the cam and tell you whether or not they will rework it. If no, you'll revert to one of the previous options. If yes, you'll pay only $131 for the welding and regrinding. You get your original cam back with a new lobe profile. Your motorcycle cam be down for weeks waiting for shipping, inspection, welding, and grinding.
6) You'll pay for the springs and retainers separately.
7) You'll pay all the shipping charges in addition to everything else.
All of a sudden, having a new cam shipped directly to Webcam really doesn't sound like that bad of an idea.
