If you're not 100% sure that you want to sell the Blaster, don't! That one appears to be in decent shape, and I can say from experience that you will have more fun on the Blasty than on any Warrior, no matter how much aftermarket work has been done to it.
A Blaster engine is also a lot easier to rebuild than the 4-stroke powerplant in a Warrior. I'm not trying to be a jerk, but for a couple hundred $$, you can probably have that Blasty back up and running nicely. Putting just a top end on a Warrior motor is a PITA, and it gets expensive quick. I traded away my '94 Warrior after realizing I'd be in at least $ 400.00 for a rebuild, just for the top end, piston, and machining. And that's only the cost of parts and machine shop fees. I have my own valve seat cutting equipment and can do the assembly/cylinder head work myself. If that wasn't the case, labor costs would drive the rebuild price up even more. Not to mention the additional estimated cost if the engine needed crankshaft or bottom end work. You can't be sure just how 'blown' your Warrior's engine is until you tear into it and start taking a look/measurments.
Have you ever done a valve job? Want to deal with valve springs? How about staggering piston ring end gaps and being sure that the camshaft is properly-timed when putting it all back together? None of these procedures are particularly difficult, but if you don't have a whole lot of experience doing internal engine work, you'd be better off starting with a simple rebuild on a 2-stroke. It shouldn't cost any more than $ 250.00 for a new top end and maybe a carb. kit while you're at it. Lack of spark is also easy to fix. You just have to track down the problem, which many people here have had to do and can help you do. Blaster electrical systems are simple, at least when compared to more complex bikes such as that Warrior. Just my .02. No offense intended. I:I
