The XR100 is a 4 stroke & will be much more reliable + its very easy to instal. the Hp is around the same as a YSR (though it can be moded to produce more.) I have one , but have yet to ride it.
If your going to go the 4 stroke rout, Id recomend a XR200 the Hp is is around 25. (the 4 strokes will be a bit mor heavy = this is because they have valves.)
The Blaster is a 2 stroke, The HP is somthing up around 30 & can run very smooth if balanced & mounted correctly. On the negitave side, you cant get a pipe any longer, so youll need to make one. Hhey handle prity good from what I hear.

A stock blaster motor puts out about 17 HP, which isn't too much.
BUT, it puts out 15LBS of torque. It has a very flat powerband and it pulls really hard all the way from idle to redline. Mine is stock and I had to lengthen the swingarm 4 and a half inches to help keep the front tire from coming up on first and second gears.
The Blaster motor doesn't rev past 8500-9000 RPM and it doesn't have that hard top end pull that you get from a YZ80, but the torque is instant and steady. I like it cuz it means I dont have to play with the gears too much while riding.
Mine got finished around February and I've ridden the crap out of it and it's been VERY reliable. I've been on 80 mile long trips where the average speed is 75mph and no problems. Just be sure to install a CHT guage, that way you ALWAYS know the temp. Get off the throttle if you see the CHT reach around 380 degrees.
As long as you keep your fuel filter and carb clean, and you premix correctly, it will be just fine. Just remember to jet the carb a little richer than needed for some added insurance. If you jet it just right on a hot day and then you go out on a cold winter night you could blow it up. I'd rather lose 2 hp by running it rich than a motor by not.
Parts availability is great, the Blaster quad was in production for a really long time and you can find parts just about anywhere.
If you're nuts for speed you can always do a mild port and get a bigger carb and you'll be hauling more ass than you'll ever need.
The pipe is not a problem anymore. When I was doing my swap Tommy Crawford wouldn't build me a pipe, he quit making them a while back. I called TCR and Susan told me to get the right hand pipe from an RZ350. Guess what? Works like a charm!!! And those pipes are cheap as hell too. All you have to do is shorten the pipe about 3 inches right after the second bend (I will post pics later).
From my own personal experience with the carb I will STRONGLY suggest that you get a stock blaster carb and jet it accordingly. I tried 3 carbs before I realized that the best running one is the stock one.
How much does it cost? Here is a brief list of things and their prices:
Used Motor: any where from 200-600 depending on condition.
I would get the cheapest one and then do a complete rebuild. That way there are no surprises.
Frame and swingarm work by Joe Huminsky. 600 if the price hasn't changed and assuming he still does it. If not you will have to mod the frame yourself. Not impossible if you know how to weld.
You use the YSR's stock wiring harness but you have to get a universal single phase regulator/rectifier so you can run a battery. This will cost about 50 bucks.
12 volt battery: 25-50
The pipe: it all depends on ebay. I got my pipes for 20 bucks (both left and right, even though I only needed one)
Universal clutch perch and Blaster clutch cable: Again it depends, but this stuff is really cheap and easy to come by.
17 tooth front sprocket and 31 tooth rear sprocket. Trust me, this is the best combo of top speed and acceleration (my opinion anyway). I've tried 2 other ratios, 17-34 and 17-28.
I was able to use a 17 tooth front sprocket from a Yamaha BW80. That way I can save money by not having to get custom made rear sprockets cuz I was able to keep the 420 chain.
Now that I know the perfect gearing though, I can tell you that you would need a 28 tooth rear and a 15 tooth front if going with the blaster front sprocket. The rear will have to be custom. But you are only buying one so no biggie. Maybe like 75-80 bucks for one.
It looks like a lot of money. But I would do it all over again. It kicks ass.
